  • Selective Recovery of Estrogenic Endocrine Disruptors from 48
           Environmental Samples Using a Substrate for Activity-Specific
           Concentration

    • Free pre-print version: Loading...

      Abstract: Abstract hER-MIP is a molecularly imprinted polymer (MIP) that has been shown to selectively collect human estrogen receptor (hER) binding active substances. However, environmental samples contain various chemicals depending on the location and regional differences, and the hER binding activity depends on the sample type. Thus, the general applicability of hER-MIP to actual environmental samples must be elucidated. In this study, 48 environmental samples were collected and screened with hER-MIP, and a yeast assay was performed to evaluate the adsorption characteristics of the samples according to the adsorption and elution fractions. The results showed that hER-MIP collects hER binding active substances almost selectively but does not collect constitutive androstane receptor (CAR) binding active substances selectively. CAR binding activity was detected in the adsorbed fraction because several hER binding active substances also demonstrate CAR binding activity.

  • Behavior of the Uptake of Ibuprofen in Five Varieties of Horticultural
           Crops Irrigated with Regenerated Water

    • Free pre-print version: Loading...

      Abstract: Abstract The current use of regenerated water in agriculture has led to the emergence of new forms of pollutants, such as pharmaceutical compounds (PCs) which are not fully eliminated in wastewater treatment plants (WWTPs). Therefore, if the effluents of such WWTPs are to be used for agricultural irrigation, the presence of PCs must be analysed and their concentrations determined. The main objective of this study was to evaluate the uptake of ibuprofen (IBP) in horticultural crops irrigated with WWTP effluents and its subsequent effect on human health due to their incorporation into the food chain. The study involved five varieties of crops (lettuce, parsley, cabbage, zucchini and broccoli) grown in a greenhouse and irrigated with WWTP effluent water, in which IBP was analysed. Of the varieties of regenerated water-irrigated horticultural crops, only the leaves of mini-romaine lettuce presented detectable levels of IBP, but without meaning any risk to human health.

  • Influence of Drought Stress and Post-Drought Rewatering on
           Phytoremediation Effect of Arabidopsis thaliana

    • Free pre-print version: Loading...

      Abstract: Globally, plants face large amounts of environmental stresses, which can inhibit their growth rate and element uptake capacity. Droughts are a critical limitation to plant growth in arid and semi-arid areas. Effects of drought stress and post-drought rewatering on the compensatory growth and Cd phytoremediation efficiency of Arabidopsis thaliana were estimated using slight and moderate drought conditions. Results showed compensatory growth can be induced by post-drought rewatering, as manifested by the increased dry weight and photosynthetic efficiency of the species under drought stress (particularly slight stress) as compared to those of the control. Slight stress increased concentrations of Cd in roots and leaves of A. thaliana by elevating its transpiration rate, whereas moderate stress induced the opposite effect. When the species was subjected to slight stress, Cd concentrations in plant tissues surpassed those in the control after rewatering, indicating that post-drought rewatering can compensate for the detrimental impacts caused by slight drought in A. thaliana. At the end of the experiment, slight and moderate drought stresses increased the Cd extraction ability of the species by 48.9% and 12.7%, respectively, compared to the control. This study demonstrates compensatory effects of post-drought rewatering on the Cd phytoextraction capacity of A. thaliana and suggests that suitable water deficit irrigation practices can enhance soil remediation efficiency and simultaneously save water in the field.

  • Phytoremediation for Co-contaminated Soils of Cadmium and Polychlorinated
           Biphenyls Using the Ornamental Plant Tagetes patula L.

    • Free pre-print version: Loading...

      Abstract: In this study, pot-culture experiments were conducted to investigate the single effect of Cd, PCBs, and the combined effect of Cd-PCBs with Tagetes patula L. The study highlights that the minimum concentration of PCBs (100 µg kg−1) could enable the growth of the plant with an increase in biomass by 27.76% when compared with the control. In all the experiments performed, the Cd concentrations over the surface parts were found to be above 100 mg kg−1. Significant positive correlations were observed between the Cd and PCBs concentrations accumulated in tissues of the soil and plants (p < 0.05). T. patula exhibited high tolerance to Cd and PCBs, and the plant promoted the removal rate of PCBs. The removal rates of PCB18 and PCB28 were up to 42.72 and 42.29%, respectively. The study highlights the potential and suitability of T. patula for phytoremediation of Cd and PCBs in contaminated soils.

  • Influence of Water Resource Recovery Facility Effluents on the Presence of
           Selected Trace Organic Contaminants (TOrCs) in the Reedy River, South
           Carolina

    • Free pre-print version: Loading...

      Abstract: Wastewater reclamation facilities are known sources of emerging contaminants associated with human health and sanitation. This study evaluated the contribution of trace organic contaminants to a previously unmonitored river by water resource reclamation facilities. Six sampling events were conducted on the Reedy River in South Carolina. Sampling locations included sites upstream and downstream of two WRRFs located on the river to examine potential contributions under drought conditions where WRRF effluents comprise a large proportion of total stream flow. Five target analytes were monitored including atrazine, carbamazepine, 17β-estradiol, perfluorooctanoic acid, and sulfamethoxazole. On a mass basis, the WRRFs contributed additional loadings of carbamazepine ranging from 5.4 g/d to 7.2 g/d (mean: 6.3 ± 0.4 g/d), PFOA ranging from 8.6 to 31.9 g/d (mean: 20.0 ± 4.9), and sulfamethoxazole ranging from 49.4 g/d to 75.1 g/d (mean: 62.1 ± 4.8). 17β-estradiol was detected once and atrazine was not detected.

  • Long-Term Toxicity of Gadolinium to the Freshwater Crustacean Daphnia
           magna

    • Free pre-print version: Loading...

      Abstract: The lanthanides are considered emerging contaminants but information on their long-term toxicity to aquatic species under environmentally relevant conditions is scarce. We aimed to fill this gap by evaluating the long-term adverse effects of gadolinium on the freshwater model—crustacean Daphnia magna. The exposure of D. magna for up to 39 days to 0.1 mg Gd/L (a 21-days chronic toxicity NOEC value derived by us formerly) in the lake water had no negative effect (p > 0.05) on vitality, size and reproduction of parent animals as well as their offspring. Thus, assumingly the current Gd contamination levels of surface waters pose no hazard to aquatic crustaceans that in general are very sensitive to various pollutants. Moreover, presence of 0.1 mg Gd/L in the lake water even mitigated the long-term toxic effect of 0.2 mg Ni/L (studied as a model co-contaminant) to D. magna’s vitality and productivity.

  • Physiological, Biochemical and Defense System Responses of Roadside
           Vegetation to Auto-Exhaust Pollution

    • Free pre-print version: Loading...

      Abstract: This study determined the effects of traffic pollutants on plants (Nerium oleander and Ricinus communis) growing along Faisalabad to Okara (R-1) and Okara to Lahore (R-2) roads in Pakistan. The photosynthetic pigments, photosynthetic rate, transpiration rate and total soluble proteins of roadside vegetation were significantly lower than control plants (50 m away from road). The average decrease in photosynthetic rate of Nerium oleander and Ricinus communis was 33.90% and 27.94% along R-1 and 41.85% and 32.409% along R-2 road, respectively. The decreased photosynthesis in roadside flora resulted in higher water use efficiency and substomatal CO2 concentration. However, higher antioxidant activity and free amino acid contents were noted in roadside plants that might be due to their defensive response to traffic pollutants. N. oleander was more affected by traffic pollutants and R. communis showed more resistance. Thus, N. oleander could be used for biomonitoring and R. communis for phytoremediation of vehicular pollution.

  • Do Manganese and Iron in Association Cause Biochemical and Genotoxic
           Changes in Oreochromis Niloticus (Teleostei: Cichlidae)'

    • Free pre-print version: Loading...

      Abstract: The present study aimed to evaluate the toxicity of the association between Fe and Mn in Oreochromis niloticus through genotoxic (micronucleus test and comet assay) and biochemical (CAT and GST enzymes) assays. The tested treatments were T1 = control group (without metal addition), T2 = 2.60 mg L−1 of Fe + 0.2 mg L−1 of Mn, and T3 = 4.40 mg L−1 of Fe + 3.49 mg L−1 of Mn, during 96-h bioassays. All animals exposed to the metals showed a significant increase in erythrocyte micronucleus frequency and DNA damage. The hepatic GST activity increased two times in animals exposed to T3 compared to the control group. The results indicate that Fe + Mn caused genotoxic and biochemical changes in exposed fish. Therefore, excess metals in ecosystems, even those essential for organisms, can be dangerous for the local biota due to the risk associated with high concentrations of these metals.

           of Congo Red Dye by Aspergillus Species

    • Free pre-print version: Loading...

      Abstract: In this work, Aspergillus terreus GS28 and Aspergillus flavus CR500 isolated from industrial waste sludge examined for the decolorization of Congo red (CR) dye. The rate of CR decolorization raised due to optimum pH, temperature, carbon, nitrogen, and heavy metals. In the comparative study, A. terreus has the maximum ability (95%) to decolorize CR (≈ 100 mg L−1) as compared with A. flavus (92.96%) under optimized condition after 120 h. GC–MS and FTIR analysis of the fungal-metabolite and fungal-biomass shows bio-degradation and biosorption processes respectively. The degraded products were benzenepropanic (Rt-26.147), 3, 4-diaminonapthelene-1-sulfonic acid, and benzenedicarboxylic acid (Rt-26.660) by A. terreus, and benzenedicarboxylic acid (Rt-41.467) by A. flavus. The phytotoxicity assay revealed that a decrease in toxicity of the degraded product towards the growth and germination rate of two plant seeds compared to CR. Thus, the finding suggests that both the fungi act promising CR remediation candidates, induces restoration of CR polluted wastewater and save soil-land.

           Soil Cr, Ni, Zn Heavy Metals in Tailings Area

    • Free pre-print version: Loading...

      Abstract: The large-scale rapid monitoring of heavy metal pollution has become a hot topic due to increasing contamination of Tailings soil by heavy metal. In order to explore the possibility of using soil spectrum to estimate the content of heavy metals in soil and realize the rapid monitoring of soil heavy metals in the Yangshanchong tailings area in Tongling, China. The spectral reflectance of soil and the content of heavy metals (Cr, Ni, Zn) in soil were determined. The optimal bands of Cr, Ni and Zn elements in soil appeared at 467 nm, 467 nm and 468 nm respectively, and the maximum correlation coefficients were − 0.716, − 0.685 and − 0.630. The inversion model of element Cr constructed under the Reciprocal Transformation Second Derivative has a better effect, and its determination coefficient R2 is 0.613; It is better to construct the model of elements Ni and Zn in the form of Reciprocal Transformation First Derivative, and their determination coefficients R2 are 0.724 and 0.603, respectively. The results of the single factor index method showed that the pollution degree of heavy metal elements in the soil in the study area is Ni > Zn > Cr; the Nemerow comprehensive pollution index method showed that the three elements in the study area were polluted to varying degrees, and the comprehensive pollution index was in order Ni > Zn > Cr; Comprehensive potential ecological hazard index evaluation, the pollution degree and ecological risk of the study area were low.

  • Selenium in Soil–Plant-Microbe: A Review

    • Free pre-print version: Loading...

      Abstract: Selenium (Se) plays an important role in geochemistry and is an essential trace element for humans and animals. This review summarizes the transformation and accumulation of Se in the plant-soil-microbe system. As one of the important reservoirs of Se, soil is an important material basis of its entry into the food chain through plants. Soil with an appropriate amount of Se is beneficial for plant growth and plays a valuable role in a stress-resistant environment. Among the many migration and transformation pathways, the transformation of Se by microorganisms is particularly important and is the main form of Se transformation in the soil environment. In this review, the role and form transformation of Se in plants, soil, and microorganisms; the role of Se in plants; the form, input, and output of Se in soil; the absorption and transformation of Se by plants; and the role of microorganisms in Se transformation are presented. In addition to describing the migration and transformation laws of Se in the environment, this review expounds on the main directions and trends of Se research in the agricultural field as well as current gaps and difficulties in Se-related research. Overall, this reviews aims to provide necessary information and theoretical references for the development of Se-rich agriculture.

  • Study on Mercury Adsorption and Desorption on Different Modified Biochars

    • Free pre-print version: Loading...

      Abstract: To develop high-performance biochar adsorbents, the adsorption ability and rate of untreated (BC-CK) and six modified biochars with amino (BC-NH), epoxy (BC-C2H2O), ethoxy (BC-C2H5O), hydrosulfuryl (BC-SH), selenium (BC-Se), and chitosan (BC-Chitosan) on Hg(II) and MeHg were investigated by simulated experiment. The results indicated that the some modified biochars (BC-NH, BC-C2H2O, BC-C2H5O and BC-Chitosan) showed lower adsorption capacity than the untreated, possibly due to the decreased specific surface area and pore volume. Whereas, BC-SH and BC-Se was improved immensely by forming stable –SH–Hg and Hg–Se with the adsorption capacity 1.26 and 1.51 times as much as BC-CK, respectively. In spite of that, Hg desorption capacities and rates of all biochars were extremely low, exhibiting great adsorption stability of biochars on Hg in another way. In addition, BC-Chitosan performed the highest adsorption speed. These provided insights on the adsorption effectiveness for Hg in the aqueous solution that was critical for evaluating the application of modified biochars.

      Abstract: Inland waters are the main medium transporting microplastics to the ocean. Aggregation, vertical settlement, and horizontal transport will occur when microplastics enter the inland waterbodies. This paper reviews these behaviors of microplastics in inland waters and their influencing factors. The aggregation of microplastics were divided into homogeneous aggregation and heterogeneous aggregation, which are critical for the settlement of microplastics. The settlement of microplastics in inland water bodies is influenced by microplastic properties (size, density, and shapes) and environmental conditions (microorganisms, sedimental properties, hydraulic conditions, and so on). Horizontal transport of microplastics in water is influenced by hydrologic conditions, rainfall, river morphologies, dams, vegetation, etc. Future perspectives including laboratory simulations and numerical models involving multiple factors, the behaviors of degradable plastics, and the influence of hydrologic conditions have been proposed.

  • Quantification of Microplastics in Soils Using Accelerated Solvent
           Extraction: Comparison with a Visual Sorting Method

    • Free pre-print version: Loading...

      Abstract: Visual sorting is a method that is widely used in microplastic analysis, but it has limitation in the quantification of small-size microplastics. Accelerated solvent extraction (ASE) which frequently used in the analysis of organic contaminants in soils and sediments was used here for the microplastics quantification. A recovery experiment using different spiked polymeric microplastics separately indicates that ASE was useful in the extraction of low-density and low-melting point polymeric microplastics. High recoveries and low matrix effects were observed for the polyethylene, polypropylene and polystyrene microplastics. A further comparison between ASE and visual sorting was conducted for seven soils from agricultural land used for long-term mulching with plastic films. The results confirmed that ASE was capable of microplastics quantification for farmland soils and polyethylene film in the ASE extracts could be identified by Fourier transform infrared spectroscopy. Meanwhile, ASE conducted on small samples (3.0 g) gave results that showed close agreement with the visual sorting method.

  • Pollution Characteristics of Microplastics in Mollusks from the Coastal
           Area of Yantai, China

    • Free pre-print version: Loading...

      Abstract: Microplastic pollution to the marine environment is a global issue. This study investigated microplastic pollution in ten species of different mollusks. Microplastic shape and size were determined under a microscope. Additionally, the polymer types were identified using Fourier transform infrared microspectroscopy (μ-FT-IR). The results showed that the microplastic abundance varied from 0.19 to 1.76 items/g (wet weight) and 4.3 to 36.6 items/individual. Four types of microplastics were observed, including fibers, fragments, films, and pellets. Fibers smaller than 500 μm were the most common. Cellophane (CP) and polyethylene terephthalate (PET) were the main polymer types. The microplastic abundance in the buried bivalve Ruditapes philippinarum demonstrated the highest level of microplastic contamination assessed by wet weight (1.76 ± 0.95 items/g). Furthermore, the Spearman correlation test showed that there was a significant negative correlation between the microplastic abundance calculated by weight and the biometric parameters (shell length, shell height and soft tissue wet weight). Our results will provide valuable information for assessment of the potential health risks of microplastics in China’s seafood.

  • Effect of Polyvinyl Chloride Microplastics on Bacterial Community and
           Nutrient Status in Two Agricultural Soils

    • Free pre-print version: Loading...

      Abstract: Knowledge of the influence of microplastics on soil microbiome and nutrients is important for understanding the ecological consequences of microplastic pollution in terrestrial ecosystems. In this study, we investigated whether polyvinyl chloride (PVC) microplastic pollution at environmentally relevant concentrations would affect soil bacterial community and available nitrogen/phosphorus content. The results showed that although PVC microplastics at 0.1% and 1% levels did not have a significant effect on overall bacterial community diversity and composition in soil over the course of 35 days, a number of bacterial genera were significantly reduced or enriched by the presence of microplastics. Potentially due to their effect on certain functional groups, microplastics caused a significant change in soil available P content. It is noteworthy that, depending on soil type, pollution level and plasticizer presence, contrasting effects of microplastics may be observed. Further research is definitely warranted to gain a clearer picture of the threats posed by microplastic pollution in soil environments.

  • Occurrence of Microplastics in Fish and Shrimp Feeds

    • Free pre-print version: Loading...

      Abstract: Plastics with particle sizes of 100 nm to 5 mm are known as microplastics. The contamination of seafood-based feeds by larger microplastics (20 μm to 5 mm) is a growing concern. Here, we analyzed fish and shrimp meals. Microplastics were extracted using density separation methods and characterized using scanning micro Fourier transform infrared spectroscopy (μ-FT-IR). The average microplastic abundance in shrimp meal was 10.7 microplastics·100 g−1. In fish meal, 1.02% of the microplastics were smaller than 1 mm, while most of the microplastics in shrimp meal were 1–5 mm. Eight colors of microplastics were observed; black, red, and orange microplastics have been rarely reported in previous studies. The microplastics found included films, fibers, and fragments, with film-type microplastics being the most common. The main chemical components of fiber-type microplastics were olefins and polyester, while film- and fragment-type microplastics were mainly paraffin and polyethylene. Additional in-depth studies of microplastics in feeds are necessary to provide data support for feed safety assessments.

  • Characteristics of Plastic Pollution in the Environment: A Review

    • Free pre-print version: Loading...

      Abstract: Plastics are ubiquitous in the environment and have become a hot topic in academic circles. Extensive studies have focused on analytical methods, source, abundance, transport, fate, degradation of plastics in the environment and threats to natural surroundings, wildlife or even human health. However, characteristics of plastic pollution, which are critical to understand this emerging problem, remain unknown up to now. Here, this paper reviews the major characteristics of plastic pollution in the environment to enhance present understanding of this issue. These characteristics, including diversity, persistence, global issues, combined pollution and threats to organisms and human health, are critically summarized in this work. Further, “plastic cycle” in the environment, namely, aquatic, atmospheric, and terrestrial system, is also discussed in this review. Finally, we highlight current challenges of plastic pollution posed to the public and also recommend the research trends in future work.

  • Socioeconomic Relation with Plastic Consumption on 61 Countries Classified
           by Continent, Income Status and Coastal Regions

    • Free pre-print version: Loading...

      Abstract: In this study, World Bank socioeconomic data of 61 countries during 2009–2015 combine with a semi-systematic literature review was applied to analyze the relationship between plastic consumptions and socioeconomic levels statistically. Based on a total data volume of 5551, we found that all countries can be divided into different groups like the continent, income status, and coastal countries. It is showed that most plastics were consumed by North America, Europe, high-income countries, and coastal countries in the Pacific and the Atlantic Ocean. A potential relation occurred in plastic consumptions with different socioeconomic parameters like Gross National Income (GNI) per capita, Gross Domestic Product (GDP) per capita, life expectancy, agriculture land use, etc. The results indicated the need should continue to support initiatives to cover identified gaps, either geographic or thematic, to address plastic consumptions.
