  • Applicability of Used Tea Leaves for Heavy Metal Retention from Industrial
           Effluents

    • Authors: Md. Misbah Uddin; Khayrun Nahar Mitu
      Pages: 187 - 191
      Abstract: Heavy metal pollution is one of the significant concerns in Bangladesh. Due to complex behavior, heavy metal requires specialized treatment; among them, adsorptive retention from aqueous solutions proved as a cost-effective technique. This study investigates the usefulness of used tea leaves for adsorptive retention of Cu2+ ions from synthetic wastewater. Series of batch experiments identify the factors affecting adsorption, such as the adsorbent dose, agitation time, and the initial metal ion concentration. Maximum 95.1% Cu2+ retained on used tea leaves within 120 minutes of agitation time. The equilibrium data show compatibility with Langmuir and Dubinin-Radushkevich isotherms. High retention capacity proves used tea leaves as one of the excellent alternative adsorption materials.

  • Ecological Perspective on the Density and Diversity of Periphytons from
           Ragda Gad Stream from Garhwal Himalaya, India

    • Authors: Pratibha Baluni
      Pages: 192 - 198
      Abstract: The present study deals with the study of Physico-chemical characteristics and the periphytic algal community of the Ragda Gad stream in district Pauri Garhwal, state Uttarakhand, India. The coordinates of this spring-fed stream are 30° 11’15” N and 78°46’22” E. During the investigation it was found that the periphytic algal community of Ragda Gad stream mainly comprised 25 taxa belonging to 3 major class namely Bacillariophyceae (Cymbella sp., Synedra sp., Fragilaria sp., Gomphonema sp., Navicula sp., Tabellaria sp., Achnanthes sp., Bacillaria sp., Diatoma sp., Amphora sp., and Nitzchia sp., etc), Chlorophyceae (Cladophora sp., Oedogonium sp., Spirogyra sp., Microspora sp., Volvox sp., Zygenema, Ulothrix sp., Closterium sp., Cosmarium sp. and Geminela sp,) and Cyanophyceae (Nostoc sp., Anabaena sp., Rivularia sp. and Phormidium sp.). The dominance of Chlorophyceae in the stream indicates the healthy condition of the stream ecosystem. It is having crystal clear water and is free from pollution. Further, as a result of less anthropogenic pressure, the quality of water is rather superior.

  • Influence of Forest Canopy Gaps on Establishment of Mikania Micrantha
           Kunth, an Invasive Plant, in a Tropical Forest in Southern Western Ghats,
           India

    • Authors: N P Sooraj; R Jaishanker, C R Sajeev, V Saroj Kumar, D Lijimol, J Ammini
      Pages: 199 - 206
      Abstract: Tropical forests are more resistant to plant invasion. However, reports of the occurrence of invasive alien plants within tropical forests have surged in recent years. The invasibility of the tropical forest ecosystem is enhanced with the disturbance mediated environmental fluctuations. The upwelling of natural light on the forest floor and associated resource fluctuation due to canopy gaps facilitate the establishment of light tolerant, invasive plants. Here the authors report the effect of the canopy gap on the establishment of M micrantha in a protected forest in Kerala, India. A significant direct relationship between the abundance of M micrantha with canopy openness and light intensity reveals how the forest canopy gap in the study area acts as a gateway to plant invasion.

  • Water Quality Assessment Using Water Quality Index and Principal Component
           Analysis: A Case Study of Historically Important Lakes of Guwahati City,
           North-East India

    • Authors: Pallavi Sharma; Priyam Jyoti Bora
      Pages: 207 - 217
      Abstract: This study evaluates the water quality of ten ancient lakes of Guwahati city, located in North east India, using water quality index (WQI) and multivariate statistical methods.The surface water samples were subjected to comprehensive physico-chemical analysis involving important physical parameters (pH, EC, TDS, alkalinity, total hardness, DO, BOD, COD, turbidity); major cations (Ca2+, Mg2+, Na+, K+), and major anions (HCO3-, Cl-, SO42-, NO3-, F-, PO43). Principal component analysis (PCA) has been used to assess the factors which influence the quality of water. The results revealed that water quality variations are mostly affected by dissolved mineral salts along with anthropogenic activities in the areas contiguous to the lakes. The present study points out that pH, DO and BOD played a central role in affecting the WQI of these lakes. The WQI values range from 74.78 to 178.55, indicating that majority of the lakes fall in “very poor” and “unsuitable” category. It also reveals an alarming fact that none of the water tanks fall under good category. Hence, the water is not fit for drinking, and is also becoming toxic for the aquatic fauna. The analysis of hydro chemical facies of the pond water shows that most of the water samples belong to Ca-Mg-HCO3 type of water. These findings will be useful for decisions making regarding water quality management and can also be applied in water modelling for better environmental management and planning perspective.

  • Interannual Variation of NDVI, Precipitation and Temperature during the
           Growing Season in Langtang National Park, Central Himalaya, Nepal

    • Authors: Ranjana Regmi; Yaoming Ma, Weiqang Ma, Binod Baniya, Barjeece Bashir
      Pages: 218 - 228
      Abstract: Vegetation is an essential component of terrestrial ecosystem, and its responses to the climate change has been recognized as a key indicator for monitoring global climate. This study analyses the temporal and spatial changes of Normalized Difference Vegetation Index (NDVI) in the Langtang National Park (LNP), Nepal, during 2000 - 2018, using the MODIS 16-day NDVI product, and the ERA-5 precipitation and temperature reanalyzes. Regression models were applied to estimate temporal trends in NDVI, and Pearson correlations between NDVI and climatic variables (i.e., temperature and precipitation) were employed to assess vegetation responses to climate change. Average annual NDVI increased significantly (0.002yr-1, p = 0.001), and the average growing season (AGS: April-October) NDVI also increased significantly (overall, 0.0023yr-1) including in spring (April-May, 0.003yr-1) and autumn (September-October, 0.002yr-1). During summer (June-August), NDVI increased by 0.002yr-1 (p> 0.05). Temperature and precipitation both increased significantly during the growing season, and significant increases in NDVI during spring in LNP indicate high levels of photosynthesis, biomass accumulation and productivity. The NDVI relative change ratio (RCR) was 12.79% during the last 19 years in LNP. The spatial distribution of NDVI increased by 30% (p < 0.05) of the area during growing season. Overall, during the AGS, 66% of the study area showed a positive correlation with temperature, of which 9.09% was significant. Positive correlation was observed between temperature and NDVI, and negative correlation between precipitation and NDVI, in the forest, shrubland, grassland and agriculture vegetation types. In the AGS, NDVI was positively correlated with temperature, but weakly related to precipitation. The results demonstrated that increasing temperature promotes vegetation growth. Quantifying the spatial response of NDVI to temperature and precipitation will support further studies on conservation and on vegetation responses to climate changes across this Himalayan national park.

           Fetida

    • Authors: B. Reddi Bhargavi; Ravi Kumar Vellanki, Rajanikanth Akurathi, Jagadeeswara Reddy Kanala
      Pages: 229 - 232
      Abstract: In this study, Eco-Genotoxic effect of two commercially available pesticides mixtures, Deltamethrin 1% + Triazophos 35% EC (D+T) and Profenofos 40% EC + Cypermethrin 4% EC (P+C), being used widely in agriculture were evaluated on earthworm Eisenia fetida. Initially LC50 for each pesticide mixture was determined by conducting acute toxicity study followed by exposing earthworms to three lowest concentrations of pesticide mixtures for 72 hours. At the end of the exposure period, the coelomocytes were isolated from the earthworm and processed for comet assay. Acute toxicity test revealed that the toxic concentration of D+T (EC) and P+C (EC) at 0.6mg/ml and 0.5mg/ml of distilled water, shown LC50 value of mortality as compare to control set of experiment. The behavior of Earthworm has been changed like body folded and less active as per the increased the dose of the toxicants. On analysis it was observed that D+T (EC) induced strand breaks at a concentration of 0.3mg/ml, whereas P+C EC induced strand breaks at 0.3 and 0.6mg/ml. From the results it is concluded that the pesticide mixtures evaluated in the study could be moderately genotoxic to earthworm Eisenia fetida.

      Pages: 233 - 238
      Abstract: Good water quality is a basic need for human health and water is naturally or artificially overlying with different trace and heavy metals. These metals have an important physiological role with the body, but the bio-toxic effects of many metals are of great health concern. Therefore, contamination of water by heavy metals could be a major concern for human health and as well as for the ecosystem. The present study deals with the elemental screening of drinking water and to compare the seasonal variation of trace and heavy metals in natural source water and their corresponding tap supply from habitat sites of Champawat district, Uttarakhand, (India). The detection of trace and heavy metals were assessed in ppm according to official method by using an Atomic absorption spectrometer. The study revealed that the concentration of trace metals such as iron, copper, manganese, zinc, and heavy metals like chromium, lead, and mercury was found within the permissible limits as prescribed by the WHO. Hence, it is concluded from the study that the amount of essential trace elements is within the permissible limit while the heavy metal was below the detectable limit. Therefore water from natural sources and their corresponding tap supplies are safe as far as trace and heavy metals are concerned.

  • Spatial Variations of Heavy Metal Content in the Surface Water of Yamuna
           River, India

    • Authors: Anita Singh; Sudesh Chaudhary, Brijnandan S. Dehiya
      Pages: 244 - 253
      Abstract: Fast-growing urbanization, industrialization, and encroachment of the river banks have increased the pollution load in the rivers. The concentrations of heavy metals like Cadmium (Cd), Chromium (Cr), Copper (Cu), Iron (Fe), Lead (Pb), Magnesium (Mn), Nickel (Ni) and Zinc (Zn) in the waters of river Yamuna were studied. Sampling was done at 41 sites from upstream in the mountainous region to confluence point with River Ganga near the city of Prayagraj. It was found that the samples from the upstream sites in the mountainous region (falling in the state of Himachal Pradesh) were less polluted than those of Delhi stretch of the river suggesting huge influence of the anthropogenic activities along the Delhi stretch of the river. Fe, Pb, Ni, Cu, Cd and Mn concentration surpassed the prescribed maximum permissible limits for drinking water all along the river, while Cr, and Zn concentration remained within the permissible limit throughout. The peak concentration of Fe, Ni, Mn and Cd were recorded along Delhi stretch and downstream from Delhi suggesting contributions from the industrial effluents of various industries such as nut-bolt industry, electroplating, and Galvanizing and cycle industries in the region. The status of various heavy metals in the water of the Yamuna River has been discussed in the present study with respect to the heavy metal pollution index (HPI). HPI for Yamuna water was found highest along the Delhi-stretch. The mean concentrations of heavy metals in sampled water of Yamuna followed the order as stated here Fe>Zn>Cu>Ni>Mn>Pb>Cr>Cd in water.

  • Antibiotics Sensitivity Patterns and Plasmid Profiles Analysis of Some
           Selected Bacteria Isolated from Septic Tank Sewage

    • Authors: Oyem Ifeanyi Mirian; Atuanya Ernest Ikenna
      Pages: 254 - 260
      Abstract: The antibiotics sensitivity patterns and plasmid profiles of some selected bacteria isolated from septic tank sewage in the region under study was evaluated. Three replicate samples from Locations A, B and C representing Agbor, Benin and Sapele regions of Delta and Edo States, Nigeria respectively was collected from both the influent tank (raw sewage) and the effluent chamber (semi treated sewage) between November 2018 and January 2019 for testing. A composite sample was formed from the three samples collected. Antibiotic resistance testing was done to determine the resistance profile of the isolates using Mueller-Hinton agar plates which were prepared and appropriately labelled. These plates were inoculated with standardized microbial broth cultures by spread plate technique and left to dry for 30 minutes. Commercially available antibiotics discs containing varying concentrations of various types of commonly used antibiotics were placed at adequate distances on each of the seeded agar plates and incubated for 12h. Plasmid DNA from all tested strains was obtained by using alkaline lysis method. Cells were grown overnight at 37oC in a nutrient broth in a 1.5 ml micro tube. The growth was harvested by centrifuging at 3,000 rpm for 10 minutes. The plasmid DNA was visualized by placing the gel in an ultraviolet transilluminator in a photo documentation system. The overall prevalence of antibiotic resistance was highest in Amoxicillin (90.5%) and least in Augmentin (40.5%). There was no significant difference (p>0.01) between antibiotic resistance in raw sewage and in the semi-treated sewage. Escherichia coli had the highest MAR index (0.9) while Proteus sp. had the lowest MAR index (0.4). Plasmid analysis of 9 bacterial isolates showed that 4 (44.4%) possessed plasmids each of molecular weight 23.1kb while 5 (56.6%) had no plasmid DNA.

  • An Exploratory Study of Impact of Lockdown on the Air Quality of Delhi

    • Authors: Nisar Khan
      Pages: 261 - 268
      Abstract: Delhi is among the most polluted cities in the World. The level of air pollution is many times the unsafe limits as prescribed by the WHO and Indian government. There have been many interventions by the government to contain the pollution like Odd-Even scheme of vehicle rationing, prohibiting heavy traffic into the city, condemning old vehicles, construction of peripheral highways etc. However, none of the interventions have been effective to provide the desired results. On the contrary the ongoing Lockdown due to Covid-19 pandemic has brought overwhelming improvement in the air quality in not only Delhi but entire country. Multiple media reports have mentioned about clear skies, cleaner air, improvement in quality of water in rivers etc. While the deterioration of environmental conditions is linked with the anthropogenic activities, the absence of these activities during the Lockdown has brought the impact into prominence. While the Covid-19 pandemic is an unprecedented health and economic crisis, it also provides a rare opportunity to study this impact. Author has carried out this exploratory research in his city of Delhi to determine the impact of Lockdown on the Air Quality.

      Pages: 269 - 272
      Abstract: Currently Nanoparticles are utilized in various fields and have a different clinical application. In our research, we have developed the Cobalt oxide (Co3O4) NPs using the Sol-gel technique from the Cobalt chloride precursor. The synthesized nanoparticle was characterized by using X-Ray Diffraction (XRD), Scanning Electron Microscope (SEM), Dynamic Light Scattering (DLS), and Fourier Transform Infra-Red Spectroscopy (FTIR). The cytotoxicity studies were evaluated on the Vero cell line (African green monkey kidney cell line) by using MTT assay at 72 hrs. The Cell viability which was observed during the process depends upon the concentration and time exposure. Moreover, the In-vitro cytotoxic effects of Co3O4 NPs showed a better result at the concentration of 50 µg/100µl in Vero cell.

      Abstract: Nowadays nanoparticles comprising the diversity of applications have been synthesized and used up in various fields. In our research, Manganese tetroxide NPs (Mn3O4) was synthesized by precipitation method. In the present investigation, antibacterial activity, as well as In-vitro cytotoxic effects of Mn3O4 NPs, have been evaluated. The cytotoxicity studies on the Vero cell line (African green monkey kidney cell line) were studied by using MTT assay at 72 hrs. The Cell viability which was observed during the process depends upon the time exposure and concentration. The antibacterial activity was evaluated against the bacteria such as Bacillus species, Escherichia coli, and Enterobacter sp. The synthesized nanoparticles were characterized using X-Ray Diffraction (XRD), Scanning Electron Microscope (SEM), Dynamic Light Scattering (DLS), and Fourier Transform Infra-Red Spectroscopy (FTIR). Moreover, In-vitro cytotoxic effects and the antibacterial activity of Mn3O4 NPs showed a better result at the concentration of 50 µg/100µl in Vero cell and the Zone of inhibition was measured for Enterobacter. This proves Mn3O4 NPs as promising biocompatible material.

    • Authors: R. Pavitra; Dr. A. Raja
      Pages: 282 - 286
      Abstract: Various textile industries are discharging toxic effluents containing azo dyes and they adversely affect the aquatic life, water resources, soil fertility and ecosystem integrity. With the goal of using microorganisms as the agent for the bioremediation in the waste water treatment containing dye has been done over the last two decades, to our best of knowledge considerable work has been not been done using actinomycetes in the treatment of dye containing waste water. In the present study, actinomycetes strain namely Micromonospora sp were isolated from textile effluent adopted soil of Tiruppur district, Tamil Nadu, India and screened for their ability to decolourize Reactive Red 35 at different parameters includes pH, agitation, nitrogen source and medium. Comparision of decolourising capacity data revealed that more effective decolorization occurs by using minimal media with peptone under static and moderately decolourised under shaking condition. The decolourising capability is found to be high at pH 8 followed by pH 6. FTIR spectrum was compared between the spectrum of RR35 and the products obtained after decolorization confirmed the biodegradation of dye. This decolorization potential suggests the applicability of this isolate for dye removal in effluent from textile industries.

During the three months study from March to May, 2018, peak colony size was observed in the month of May. At Pan Bajar roosting site, the total colony size of Indian flying fox was 1,137±10 in March, 1,345±10 in April and 1,380±10 in May. Eight species of roosting trees were observed which included Eucalyptus globusus, Delonix regia, Ficus religiosa, Ficus benghalensis, Tamarindus indica, Polyalthia longifolia, Mangifera indica and Grevillea robusta. In the Judge filed roosting site, only two types of roosting trees were observed namely Eucalyptus globusus and Polyalthia longifolia. Here, the total colony size of was 152±10 in March, 170±10 in April and 179±10 in May. In both the cases, the bats have chosen large, tall and well exposed tree species as their roost. The roosting sites were also seen to be in close proximity to water bodies. The study also showed that increase in the built up area was posing a threat to the species which is playing a very important ecological role in seed dispersion and pollination. Further felling of trees in this rapidly growing metropolitan area will lead to complete extinction of this species from the urban landscape of Guwahati city.

      Abstract: Drought is a prolonged shortage in the water supply and considered to be the most complex but least understood of all-natural hazards. The current study utilizes 47 years of data for drought assessment to understand drought patterns and severity. All drought-prone districts in the study area experience famine that is still slow-onset, creeping, and a recurrent occurrence. The spatio-temporal behavior of meteorological drought was investigated by calculating the Standard Precipitation Index (SPI) and spatial distribution of droughts by ArcGIS software. The SPI index is useful for the determination of drought conditions at diverse time scales and monitoring different types of drought. This index captured the collected deficit (SPI< 0) or extra (SPI> 0) of precipitation over a specified period. In the current investigation, 1972, 2000, and 2014 chosen as representative drought years based on negative SPI trends. The spatial pattern shows the area of agricultural drought increased during the kharif crop season (June - Oct). Based on the acquired result it is reveals that the SPI is an indicative parameter for assessment of agricultural drought in the Marathwada region. It also provides useful information to create a decision support system for agricultural drought or arid condition avoidance, mitigation, along with irrigation management improvement.

  • Assessing the Effects of Land Use/Land Cover Change on Discharge Using
           SWAT Model in River Ruiru Watershed, Kiambu County, Kenya

    • Authors: Ann Waithaka; Shadrack Murimi, Kennedy Obiero
      Pages: 303 - 314
      Abstract: Watersheds and water resources are highly vulnerable to land use/land cover changes (LULCC) as they directly influence hydrological characteristics in terms of water quantity. This study aimed at assessing the effects of land use/land cover changes (LULCC) on Surface runoff contribution to discharge (SURQ), lateral flow contribution to discharge (LATQ) and groundwater contribution to discharge (GWQ) of River Ruiru watershed, Kiambu County. The study integrated the use of remote sensing, GIS and hydrological modeling to collect and analyze data. Results of the study indicated that built-up areas, annual crops (mixed farming) and perennial crops (Tea and coffee farming) increased by 1.83%, 15.05% and 10.90% from 1984 to 2017 while grassland, shrubland and forestland decreased by 6.21%, 11.92% and 10.06%. Consequently, SWAT model results indicated that land use/land cover changes that occurred in River Ruiru watershed between 1984 and 2017 had effects on Surface runoff (SURQ), lateral flow (LATQ) and groundwater contribution to discharge (GWQ) which increased from 30.25 mm/yr, 8.48mm/yr and 9.95mm/yr to 181.25mm/yr, 11.44mm/yr and 10.66mm/yr respectively. The results from this study will help in understanding the effects of LULCC on the quantity of discharge which is one component of the knowledge base required in applying the principles of integrated water resources management (IWRM) thus providing critical input to the decision making on water resources management and planning.
