  • Fragranced consumer products: effects on autistic adults in the United
           States, Australia, and United Kingdom
    • Authors: Anne Steinemann
      Pages: 1137 - 1142
      Abstract: Fragranced consumer products, such as cleaning supplies, air fresheners, and personal care products, can have adverse effects on both air quality and health. This study investigates the effects of fragranced products on autistic individuals ages 18–65 in the United States, Australia, and United Kingdom. Nationally representative population surveys (n = 1137; 1098; 1100) found that, across the three countries, 4.3% of adults (n = 142) report medically diagnosed autism (2.3%), an autism spectrum disorder (2.4%), or both. Of these autistic adults, 83.7% report adverse health effects from fragranced products, including migraine headaches (42.9%), neurological problems (34.3%), respiratory problems (44.7%), and asthma attacks (35.9%). In particular, 62.9% of autistic adults report health problems from air fresheners or deodorizers, 57.5% from the scent of laundry products coming from a dryer vent, 65.9% from being in a room cleaned with scented products, and 60.5% from being near someone wearing a fragranced product. Health problems can be severe, with 74.1% of these effects considered potentially disabling under legislation in each country. Further, 59.4% of autistic adults have lost workdays or lost a job, in the past year, due to fragranced product exposure in the workplace. More than twice as many autistic as well as non-autistic individuals would prefer that workplaces, health care facilities, and health care professionals were fragrance-free rather than fragranced. Results show that vulnerable individuals, such as those with autism or autism spectrum disorders, can be profoundly, adversely, and disproportionately affected by exposure to fragranced consumer products.

  • Analysis of fungal contamination in vehicle air filters and their impact
           as a bioaccumulator on indoor air quality
    • Authors: Simone Aquino; José Eduardo Alves de Lima; Ana Paula Branco do Nascimento; Fabrício Caldeira Reis
      Pages: 1143 - 1153
      Abstract: Studies on air quality within automotive vehicles are an emerging research area in Brazil, especially in the city of São Paulo, one of the most polluted cities in the world and with the largest fleet of vehicles in the country. Indoor air quality is an indicator of environmental health that takes into account, in addition to thermal comfort, factors that interfere in precarious air conditions, such as the presence of fungi, bacteria and carbon dioxide in indoor air-conditioned environments. The objective of the present study was to analyse the fungal contamination in air-conditioning filters collected from 21 automotive vehicles and the study found 17 fungal genera in all samples collected (100%), including toxigenic fungi such as Penicillium, Fusarim and Aspergillus, indicating that indoor air quality can compromise the health of a portion of the population, such as professional drivers. Among the Aspergillus genus, the results showed the presence of the A. flavus, A. niger, A. fumigatus, A. ochraceus and A. clavatus species, which cause severe allergic and pulmonary respiratory diseases. Air in artificially heated environments should provide comfort to its occupants but it may pose a risk to human health if the car filtration system is contaminated by pathogenic fungi.

  • Comparing different methods for statistical modeling of particulate matter
           in Tehran, Iran
    • Authors: Vahid Mehdipour; David S. Stevenson; Mahsa Memarianfard; Parveen Sihag
      Pages: 1155 - 1165
      Abstract: Particulate matter has major impacts on human health in urban regions, and Tehran is one of the most polluted metropolitan cities in the world, struggling to control this pollutant more than any other contaminant. PM2.5 concentrations were predicted by three statistical modeling methods: (i) decision tree (DT), (ii) Bayesian network (BN), and (iii) support vector machine (SVM). Collected data for three consecutive years (January 2013 to January 2016) were used to develop the models. Data from the initial 2 years were employed as the training data, and measurements from the last year were used for testing the models. Twelve parameters, covering meteorological variables and concentrations of several chemical species, were explored as potential predictors of PM2.5. According to the sensitivity analysis of PM2.5 by SVM and derived explicit equations from BN and DT, PM10, NO2, SO2, and O3 are the most important predictors. Furthermore, the impacts of the predictors on the PM2.5 were assessed which the chemical precursors’ influences indicated more in comparison with meteorological parameters. Capabilities of the models were compared to each other and the support vector machine was found to be the best performing, based on evaluation criteria. Nonetheless, the decision tree and Bayesian network methods also provided acceptable results. We suggest more studies using the SVM and other methods as hybrids would lead to improved models.

  • Characteristics of PM 2.5 and its chemical constituents in Beijing, Seoul,
           and Nagasaki
    • Authors: Eun Ha Park; Jongbae Heo; Setsuko Hirakura; Masahiro Hashizume; Furong Deng; Ho Kim; Seung-Muk Yi
      Pages: 1167 - 1178
      Abstract: Ambient fine particulate matter (PM2.5) samples were collected from September 2013 to May 2015 in three cities in East Asian countries (Beijing, China; Seoul, South Korea; and Nagasaki, Japan) in order to analyze the spatiotemporal trends of PM2.5 chemical constituents including organic matter (OM), elemental carbon (EC), water-soluble inorganic ions (NO3−, SO42−, and NH4+), and trace elements. The average PM2.5 mass concentration were 125 ± 6.80 μg m−3, 44.6 ± 0.84 μg m−3, and 17.4 ± 0.37 μg m−3 in Beijing, Seoul, and Nagasaki, respectively. Higher carbonaceous concentrations were observed during winter in Beijing and Seoul, while higher concentrations were found during spring in Nagasaki. The highest seasonal averages of organic carbon (OC) to EC ratios were found during spring in Beijing, winter in Seoul, and fall in Nagasaki. The concentrations of secondary OC and its ratio to OC were high during fall and winter. For ion species, NO3− was dominant in Beijing and Seoul, while SO42− was dominant in Nagasaki. Increased contributions of mobile sources in Beijing and Seoul were observed, with higher NO3−/SO42− ratios than those in Nagasaki. Three groups of air masses were found for the three cities using cluster analyses based on 72-h backward trajectories. The cluster from the Bohai economic zone had the highest concentration of PM2.5 for Beijing. For Seoul, a cluster that originated from the Yellow Sea near an industrial area in Liaoning Province and passed through a highly polluted industrial area in southwestern Seoul had high PM2.5 concentrations. A long-range transported cluster that originated in and crossed through heavily industrialized areas in China and South Korea for Nagasaki had higher ion species concentrations. The results of this study are useful to identify the current levels of PM2.5 and its chemical properties to establish a control plan for PM2.5 for Northeast Asia, including China, South Korea, and Japan.

  • Spatio-seasonal variation in ambient air pollutants and influence of
           meteorological factors in Coimbatore, Southern India
    • Authors: A. Manju; K. Kalaiselvi; V. Dhananjayan; M. Palanivel; G. S. Banupriya; M. H. Vidhya; K. Panjakumar; B. Ravichandran
      Pages: 1179 - 1189
      Abstract: Air quality is used worldwide to confirm the current status of air pollution level and associated health risks to the public. Several air pollutants reach very high concentrations in many regions across India. In this study, air pollutants were measured in an urban city of Coimbatore, Tamil Nadu, Southern India, during 2013 to 2014 based on season and location, and the influence of meteorological factors. Air pollutants (PM10, PM2.5, SO2, NO2, CO, and O3) across eight locations including industrial, residential, traffic, and commercial areas were assessed. The results showed that PM10, PM2.5, and CO were the most serious pollutants and their average concentrations ranged from 65.5 to 98.6 μg/m3, 27.6 to 56.9 μg/m3, and 1.58 to 8.21 mg/m3, respectively, among various locations. Significantly higher concentration of air pollutants was recorded in industrial areas followed by traffic and commercial areas. Comparatively higher mean concentration of O3 (2.22 ± 0.75 μg/m3) and CO (7.73 ± 1.86 mg/m3) was recorded during the summer season, whereas the concentration of PM10 (80.3 ± 24.4 μg/m3), PM2.5 (45.1 ± 17.7 μg/m3), SO2 (7.86 ± 1.55 μg/m3), and NO2 (13 ± 1.81 μg/m3) was higher in southwest monsoon. Ozone (O3) and CO positively correlated with temperature and negatively correlated with relative humidity. The level of PM10, PM2.5, and CO concentrations exceeded the National Ambient Air Quality Standards (NAAQS) guidelines. The present study’s results emphasize the need of effective air pollution control in Coimbatore. Precautionary measures to be taken to avoid exposure of air pollutants to the public and minimize pollutants. This study further suggests an investigation on the adverse impact on human health and environment using appropriate risk analysis techniques.

  • Can houseplants improve indoor air quality by removing CO 2 and increasing
           relative humidity'
    • Authors: C. Gubb; T. Blanusa; A. Griffiths; C. Pfrang
      Pages: 1191 - 1201
      Abstract: High indoor CO2 concentrations and low relative humidity (RH) create an array of well-documented human health issues. Therefore, assessing houseplants’ potential as a low-cost approach to CO2 removal and increasing RH is important. We investigated how environmental factors such as ‘dry’ (< 0.20 m3 of water per m3 of substrate, m3 m−3) or ‘wet’ (> 0.30 m3 m−3) growing substrates, and indoor light levels (‘low’ 10 μmol m−2 s−1, ‘high’ 50 μmol m−2 s−1, and ‘very high’ 300 μmol m−2 s−1) influence the plants’ net CO2 assimilation (‘A’) and water vapour loss. Seven common houseplant taxa—representing a variety of leaf types and sizes—were studied for their ability to assimilate CO2 across a range of indoor light levels. Additionally, to assess the plants’ potential contribution to RH increase, the plants’ evapo-transpiration (ET) was measured. At typical ‘low’ indoor light levels, ‘A’ rates were generally low (< 3.9 mg h−1). Differences between ‘dry’ and ‘wet’ plants at typical indoor light levels were negligible in terms of room-level impact. Light compensation points (i.e. the light level where the CO2 assimilation equals zero) were in the typical indoor light range (1–50 μmol m−2 s−1) only for two studied Spathiphyllum wallisii cultivars and Hedera helix; these plants would thus provide the best CO2 removal indoors. Additionally, increasing indoor light levels to 300 μmol m−2 s−1 would, in most species, significantly increase their potential to assimilate CO2. Species which assimilated the most CO2 also contributed most to increasing RH.

  • Roadside atmospheric pollution: still a serious environmental problem in
           Beijing, China
    • Authors: Wei Chen; Aijia Li; Fan Zhang
      Pages: 1203 - 1216
      Abstract: China has made great efforts to reduce ambient atmospheric pollutant concentrations in the past few decades. The air quality in northern China has improved greatly. However, most research has focused on atmospheric pollution in non-roadside environments that have little influence from traffic flow and are impacted by less vehicle exhaust. In this study, hourly air quality monitoring data were collected at four traffic stations and four nontraffic stations in Beijing from June 2014 to September 2017 to analyze the spatial-temporal variations of atmospheric pollutants related to traffic. The traffic stations had higher concentrations of PM2.5, PM10, SO2, NO2, and CO but lower concentrations of O3. Although the overall air quality in Beijing is improving, the pollution rates of PM2.5, PM10, and NO2 in the traffic stations were still high at 47.91%, 50.71%, and 61.22% concentrations, respectively. The air pollution levels in traffic environments are systematically higher than those in nontraffic environments, during both daytime and nighttime, except O3. Furthermore, the traffic stations near ring roads with large numbers of diesel trucks were even more polluted, suggesting the influence of traffic emissions. Under adverse meteorological dispersion conditions, both the traffic and nontraffic stations had high pollution levels, but the pollution at the traffic stations was much higher. To reduce the air pollution level, a series of vehicle restriction rules have been imposed, including license plate restriction. Our analysis revealed obvious cycles associated with license plate restriction rules, suggesting the possibility for further improvement in vehicle restriction rules. The results from our study suggest that roadside environments with heavy traffic in Beijing, China, are still highly polluted and need further efforts to improve.

  • Influence of different complexity levels of road traffic models on air
           quality modelling at street scale
    • Authors: Bruno Vicente; Sandra Rafael; Vera Rodrigues; Hélder Relvas; Mariana Vilaça; João Teixeira; Jorge Bandeira; Margarida Coelho; Carlos Borrego
      Pages: 1217 - 1232
      Abstract: Urban mobility accounts for 38 and 19% of nitrogen oxide (NOx) and particulate matter (PM) emissions at European urban areas, respectively. Despite of all the technological development around automobile industry, urban areas are still facing problems related to exposure to high levels of air pollutants. Increasing the accuracy of both emissions and air quality modelling from road traffic is a key-issue for the management of air pollution in road transport sector. This study assessed the influence of using different road traffic emission models on the accuracy of air quality modelling with street-level resolution, having as a case study an urban area located on the centre region of Portugal. Two emission models, with different complexity levels regarding the ability to characterise the traffic dynamics were analysed, namely, transport emission model for line sources (TREM) and vehicle-specific power (VSP), based on data obtained in an experimental campaign. To perform the air quality simulations, the pollutant dispersion in the atmosphere under variable wind conditions (VADIS) model was used and two pollutants were analysed: NOx and PM10. The results showed that the magnitude of PM10 and NOx concentrations were result of a conjoint influence of traffic dynamics and meteorological conditions. Comparison between measured and modelled data showed that the VADIS model could track the evolution of NOx levels, for both emission models considered, displaying a high correlation (> 0.8) between traffic-related NOx emissions and NOx concentrations. For PM10, VADIS model is more sensitive to the differences in the emissions calculation; however, it was observed that the traffic-related PM10 emissions accounts 1.3–8.4% to the PM10 concentration levels at the study area.

  • Performance of silver, zinc, and iron nanoparticles-doped cotton filters
           against airborne E. coli to minimize bioaerosol exposure
    • Authors: Attarad Ali; Maohua Pan; Trevor B. Tilly; Muhammad Zia; Chang Yu Wu
      Pages: 1233 - 1242
      Abstract: To overcome limitations of existing air-cleaning filters in capturing and deactivating aerosolized microorganisms, this study was embarked to evaluate novel Ag, Zn, and Fe nanoparticle-doped cotton filters (AgCt, ZnCt, FeCt), as biocidal filters for bioaerosol attenuation. To evaluate the biocidal activity of the nanocomposite filters, the survival of lab-generated E. coli after collection on each filter material was compared to collection on an undoped cotton control filter and in a BioSampler. Relative humidity (RH) affected the survival of bacteria on the filters, and the optimal RH was found to be 50 ± 5%. The physical removal efficiency (PRE) determined by an optical particle counter was 99.9 ± 0.7% for ZnCt, 97.4 ± 1.2% for AgCt, and 97.3 ± 0.6% for FeCt, where the control showed only 77.4 ± 6.3% for particles > 500 nm. The doped filters showed 100% viable removal efficiency (VRE). Importantly, the VRE of the nanocomposite filters after four cycles remained nearly 99% and was greater than the cotton control filter at 76.6 ± 3.2%. Adding to its benefits, the AgCt filters had a lower pressure drop than the FeCt and ZnCt filters and the cotton control. The permeability for the cotton control filter was 3.38 × 10−11 m2 while that for the AgCt filter was slightly higher (3.64 × 10−11 m2) than the other filters as well. Overall, these results suggest that nanocomposite-doped filter media, particularly AgCt, can provide effective protection against airborne pathogens with a lower pressure drop, elevated collection efficiency, and better disinfection capability as compared to untreated cotton filters, which are all important features for practical biocidal applications.

  • Asian dust storms and diabetes hospitalization: a nationwide
           population-based study
    • Authors: Yun-Shan Chan; Joshua Chen-Yuan Teng; Tsai-Ching Liu; Yu-I Peng
      Pages: 1243 - 1250
      Abstract: This study analyzed the association between Asian dust storms events and diabetes hospital admissions during 2000–2009 in Taiwan using time-series autoregressive model with explanatory variables. Data came from National Health Insurance Research Database, Taiwan Environmental Protection Agency, and Central Weather Bureau. There were 1,283,509 diabetes hospital admissions and 55 ADS events. Our study showed that Asian dust storms were positively associated with diabetes hospital admissions for women, but the connection was delayed rather than immediate. The females who were aged above 74 and who were active in the labor market were more vulnerable to Asian dust storms.

  • Decontamination of Diesel particles from air by using the Counterfog®
    • Abstract: The existence of particles with diameter under 10 μm in air is strongly correlated with respiratory diseases. These particles are profusely produced by heating systems, traffic, and Diesel engines creating a serious problem to modern cities. Natural mechanisms removing particles from the atmosphere are too slow to deal with the huge amount of particles daily released by human activity. The objective of this work is to measure the effectiveness of a new technology called Counterfog® to eliminate airborne particles. The results show that Counterfog® is able to wash out PM10, PM5, and PM2.5 Diesel-generated airborne particles quite efficiently.

  • Examination of in-cloud sulfate chemistry using a different model
    • Abstract: We first examine characteristics of in-cloud sulfate chemistry of a mid-latitude convective cloud using a different model initialization. Specifically, we studied the relative importance of convection on sulfate aerosol transport and redistribution. The analysis is focused on 4 April 2000, when considerable dust transport is evidenced with high concentration and wet deposition of sulfate aerosol measured at the European Monitoring Environmental Program (EMEP) station located in the western mountain part of the Republic of Macedonia. The cloud-resolving model coupled with aqueous sulfate chemistry module has been employed to simulate the sulfate aerosol aqueous chemistry and wet deposition. The modeled results and sensitivities under various initializations are evaluated and compared with a ground-based measurements and laboratory analysis. The results indicate that the local environmental profiles derived from 2.5 km-scale WRF model provides a better cloud model initialization, capable of realistic representation of sub-grid-scale processes which are not adequately resolved by the WRF model with a coarser grid resolution. The method also shows a relatively good performance in simulation of cloud physical processes which take place in-cloud and the near cloud environment, cloud-chemistry interactions, relevant to sulfate acidification and sulfate deposition, which allows a more accurate quantitative assessment of sulfate concentration and pH values. Analysis also indicated that scavenging and oxidation are the principal processes affecting sulfate production, participating with 33 and 46%, respectively. Turning off the ice-phase processes leads to overprediction of sulfate aerosol production for about 8% relative to the base run. The verification analysis indicates that the numerical simulation initialized with a 2.5-km-scale WRF model shows a higher correlation coefficient with observations compared to other runs. This approach of initialization based on WRF conditions provides a scientific contribution by evaluating simulations of convective clouds in Macedonia against ground-based meteorological and chemical data, as well as by using the model to understand the driving processes affecting sulfate production and wet deposition.

  • (1 → 3) β-Glucan induces multimodal toxicity responses in parallel
           exposures of model human lung epithelial cells and immature macrophage
    • Abstract: Many epidemiological studies have associated bioaerosol exposures with a variety of adverse health effects; however, the role of bioaerosol components in the development and manifestation of hypersensitivity and non-infectious respiratory diseases remains unclear. Despite many studies which have examined allergic responses to bioaerosols, less is known about non-allergenic effects. In order to elucidate the mechanisms by which bioaerosols can exert non-atopic stresses on a cellular level, there is a need for improving existing in vitro approaches. In response, a cohort of toxicology assays were optimized to create a robust analytical suite for studying the effects that biogenic atmospheric pollutants generate on two model human lung cell lines (A549 epithelial line and GDM-1 immature macrophage line). To demonstrate the utility for studying the cellular responses to select bioaerosols, cells exposed to curdlan (a linear (1 → 3)-β-glucan) were examined in a composite cytometry platform. Results suggest that curdlan has the potential to elicit significant responses in A549 and GDM-1 in two or more toxicological modes associated with exposure to airborne particulate matter. As designed, this suite provided a more powerful tool for characterizing curdlan-induced toxicological potential than any individual assay. Responses to curdlan were distinctly modal and cell line dependent, suggesting that the use of a suite of toxicological assays, in a common platform on different cell lines, can help provide important insights into the formative toxigenic responses that primary bioaerosols can induce in respiratory cells.

  • Temporal and regional change of some air pollution parameters in Bursa
    • Authors: Mehmet Cetin; Ayse Kalayci Onac; Hakan Sevik; Busra Sen
      Abstract: Air pollution is one of the most important problems that modern urban life brings nowadays. Every year, thousands of people are affected by air pollution and it even causes deaths. There are certain places and hours that the air pollution is more intense in the cities, which is especially problematic for people with various health problems and this situation affect people’s quality of life negatively. For this reason, measuring regional and temporal changes of air pollution by scientific studies will guide the determination of the precautions to avoid negative effects of air pollution on people’s health. The purpose of this study is to evaluate the air quality based on CO2 amount and amount of particulate matter in 6 different dimensions (0.3-μm, 0.5-μm, 1.0-μm, 2.5-μm, 5.0-μm, and 10.0-μm dimensions), and to determine the change in sound level on a regional basis depending on the time of day and the season in different areas of Bursa city center. The results of the study showed that the effect of season on noise and CO2 was statistically insignificant, but the particulate matter dimensions are affected at statistically 99.9% confidence level by season. On the other hand, results of the analyses held during the study showed that time factor affects all parameters except noise parameter and the amount of large size (5 and 10); and the place factor effects all the parameters except the amount of particulate matter of size 2.5 and 5.0. The location season time factor was found to be effective at 99.9% confidence level over all parameters.

  • The effects of roadside vegetation characteristics on local, near-road air
    • Authors: Parikshit Deshmukh; Vlad Isakov; Akula Venkatram; Bo Yang; K. Max Zhang; Russell Logan; Richard Baldauf
      Abstract: Roadside vegetation has been shown to impact downwind, near-road air quality, with some studies identifying reductions in air pollution concentrations and others indicating increases in pollutant levels when vegetation is present. These widely contradictory results have resulted in confusion regarding the capability of vegetative barriers to mitigate near-road air pollution, which numerous studies have associated with significant adverse human health effects. Roadside vegetation studies have investigated the impact of many different types and conditions of vegetation barriers and urban forests, including preserved, existing vegetation stands usually consisting of mixtures of trees and shrubs or plantings of individual trees. A study was conducted along a highway with differing vegetation characteristics to identify if and how the changing characteristics affected downwind air quality. The results indicated that roadside vegetation needed to be of sufficient height, thickness, and coverage to achieve downwind air pollutant reductions. A vegetation stand which was highly porous and contained large gaps within the stand structure had increased downwind pollutant concentrations. These field study results were consistent with other studies that the roadside vegetation could lead to reductions in average, downwind pollutant concentrations by as much as 50% when this vegetation was thick with no gaps or openings. However, the presence of highly porous vegetation with gaps resulted in similar or sometimes higher concentrations than measured in a clearing with no vegetation. The combination of air quality and meteorological measurements indicated that the vegetation affects downwind pollutant concentrations through attenuation of meteorological and vehicle-induced turbulence as air passes through the vegetation, enhanced mixing as portions of the traffic pollution plume are blocked and forced over the vegetation, and through particulate deposition onto leaf and branch surfaces. Computational fluid dynamic modeling highlighted that density of the vegetation barrier affects pollutant levels, with a leaf area density of 3.0 m2 m−3 or higher needed to ensure downwind pollutant reductions for airborne particulate matter. These results show that roadside bushes and trees can be preserved or planted along highways and other localized pollution sources to mitigate air quality and human health impacts near the source if the planting adheres to important characteristics of height, thickness, and density with full coverage from the ground to the top of the canopy. The results also highlight the importance of planting denser vegetation and maintaining the integrity and structure of these vegetation barriers to achieve pollution reductions and not contribute to unintended increases in downwind air pollutant concentrations.

  • Emissions from dryer vents during use of fragranced and fragrance-free
           laundry products
    • Authors: Nigel B. Goodman; Amanda J. Wheeler; Phillip J. Paevere; Giovanni Agosti; Neda Nematollahi; Anne Steinemann
      Abstract: Fragranced laundry products emit a range of volatile organic compounds, including hazardous air pollutants. Exposure to fragranced emissions from laundry products has been associated with adverse health effects such as asthma attacks and migraine headaches. Little is known about volatile emissions from clothes dryer vents and the effectiveness of strategies to reduce concentrations and risks. This study investigates volatile emissions from six residential dryer vents, with a focus on d-limonene. It analyses and compares concentrations of d-limonene during use of fragranced and fragrance-free laundry products, as well as changes in switching from fragranced to fragrance-free products. In households using fragranced laundry detergent, the highest concentration of d-limonene from a dryer vent was 118 μg/m3 (mean 33.34 μg/m3). By contrast, in households using only fragrance-free detergent, the highest concentration of d-limonene from a dryer vent was 0.26 μg/m3 (mean 0.25 μg/m3). After households using fragranced detergent switched to using fragrance-free detergent, the concentrations of d-limonene in dryer vent emissions were reduced by up to 99.7% (mean 79.1%). This simple strategy of switching to fragrance-free products significantly and almost completely eliminated d-limonene emissions. Results from this study demonstrate that changing from fragranced to fragrance-free products can be a straightforward and effective approach to reduce ambient air pollution and potential health risks.

  • In situ NO abatement by photocatalysis—study under continuous NO
           injection in a 10-m 3 experimental chamber
    • Authors: Jivko Topalov; Julie Hot; Erick Ringot; Alexandra Bertron
      Abstract: Air pollution is a serious public health concern in France and many other countries. Nitrogen oxides (NOx) include nitrogen monoxide (NO) and nitrogen dioxide (NO2). They are mainly outdoor pollutants produced during combustion of fossil fuel. These gases can easily infiltrate buildings and thus increase indoor pollution. The recommended guideline values for NO2 are 200 μg/m3 (short-term exposure) and 40 μg/m3 (long-term exposure). Although no guideline values exist for NO, this gas can be oxidised by atmospheric ozone and thus produce NO2. This paper studies the depollution efficiency of photocatalysis towards indoor NO. Experiments were conducted at real scale, in a 10-m3 experimental chamber developed at the LMDC and used as a reactor. The interior walls of the chamber were equipped with painted plasterboards treated with photocatalytic coating (3 g/m2 of TiO2). Gas was continuously injected into the chamber according to a specific procedure: (1) pollutant injection at high flow rate to reach 200 ppb of NO, (2) pollutant injection at low flow rate in order to keep the NO concentration constant at 200 ± 10 ppb and (3) photocatalysis activation by switching on the light. Typical indoor lighting systems (fluorescent tubes, LED and halogen bulbs) were tested and UV fluorescent tubes were also used to optimise the photocatalytic efficiency. Results showed that NO indoor concentration was reduced by photocatalysis in real-world conditions. Significant NO degradation was obtained under visible light. In addition, using the experimental procedure presented in this paper, a new method for evaluating air depollution efficiency by photocatalysis at real scale is proposed.

  • Analysis of dust wet deposition in the mid-latitudes of the Northern
    • Authors: Zhenxi Zhang; Wen Zhou; Liangui Yang
      Abstract: Wet deposition is the efficient removal process for fine dust aerosol. Dust wet deposition in the mid-latitudes of the Northern Hemisphere is investigated in this study by analyzing the dust simulations with the Global Ozone Chemistry Aerosol Radiation and Transport (GOCART) model, measurements from Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations (CALIPSO), and the meteorological and hydrological fields from Modern Era-Retrospective Analysis for Research and Applications (MERRA) reanalysis. The dust aerosol optical depth (AOD) and dust extinction coefficient from CALIPSO observation and GOCART simulation, in conjunction with the wind field from MERRA, show that the dust plume extending eastward from Asia to Pacific in the mid-latitudes becomes strongest in spring, while Taklamakan, Sahara, and Gobi dust are the main components and distribute vertically in the upper, middle, and lower parts of the dust layer across North Pacific, respectively. The wet deposition of dust in the mid-latitudes is mainly in the large-scale wet removal process, which becomes strongest in spring. The occurrence of wet deposition is accompanied by dust loading or transport. The comparison of wet deposition from GOCART simulation with the cloud water mixing ratio and precipitation production rate from MERRA indicated that wet deposition is mainly related to the water amount in ice cloud, and has a positive relationship with the precipitation in ice cloud layer. On the other hand, over arid and semiarid regions in central and eastern Asia with high dust loading, the absence of cloud water caused by the semidirect effect of dust (Huang et al., Geophys Res Lett 33(19), 2006b), can lower the amount of wet deposition. The comparison of wet deposition from GOCART simulation with the cloud water mixing ratio and vertical pressure velocity from MERRA demonstrates that a large-scale dynamic process, the ascending motion in the subpolar low-pressure system over the North Pacific, can increase the water amount in cloud and cause much more wet deposition of dust, which explains the occurrence of the largest wet deposition over the North Pacific.

  • Day-night variability of PM 10 components at a Mediterranean urban site
           during winter
    • Authors: Nuria Galindo; Eduardo Yubero; Jose F. Nicolás; Montse Varea; Álvaro Clemente
      Abstract: Daytime and nighttime PM10 samples were collected during winter at an urban site in Southeastern Spain. Samples were subsequently analyzed to determine the concentrations of water-soluble ions, carbonaceous species, and metals. PM10 daytime and nighttime concentrations were 26.1 and 20.6 μg/m3, respectively. This difference may be mainly attributed to the reduction in the number of vehicles during nighttime. Traffic-related components such as EC, Ca and other crustal elements, Cu or Zn, showed statistically significantly higher concentrations during daytime, suggesting that traffic emissions were more relevant than day-to-night differences in meteorological conditions. In contrast, no significant differences between daytime and nighttime levels of secondary inorganic ions (SO42−, NO3− and NH4+) were found. Primary and secondary organic carbon concentrations were estimated using the EC tracer method. As expected, POC levels were greater during the day due to increased vehicle exhaust emissions; conversely, higher SOC concentrations were registered during the nighttime period. This was most likely the result of a significant contribution of nighttime chemistry to the formation of secondary organic aerosols.
