Subject: Biodegradation Of White Chicken Feather Waste Pollutants By Bacteria
Keywords: Bacillus licheniformis DAS-2-NKR6, SDS-PAGE, chicken feathers, Biodegradation
Abstract: Biodegradation of white chicken feather by isolated keratinolytic bacteria, like NKR1-NKR9 was most effective. The bacterial strain Bacillus licheniformis DAS-2-NKR6 was more effective for degradation of chicken feathers. The other identified bacterial strain NKR1 grew very well till 550C but its keratinolytic activity was restricted to 460C. NKR6 bacterial strain was also grew well but it produces peptidase only between 20-450C. The keratinase enzyme was purified by ammonium sulphate precipitation. The highest purification factor of our strain was 3.7-fold for strain NKR-6 and the final yield was 17.6%. Specific activity of enzyme had 34.02 U/mg where feather keratin act as substrate. SDS-PAGE was used for the determination of molecular weight of purified enzyme. Purified enzyme showed single band with molecular wt. of 43 kDa whereas crude enzyme showed multiple bands, compared with the protein marker range 14-80 kDa.

Subject: Measurement Of Nitrogen Dioxide Emissions From The Industrial City Of Sahab In Jordan
Keywords: Nitrogen dioxide, Air pollution, Statistical analysis, Sahab industrial estate, Meteorological parameter
Abstract: The average emission rates of nitrogen dioxide (NO2) have been measured in the city of Sahab, southeast of Amman, Jordan. Sahab is a famous city for its industrial estate. Data obtained from the Ministry of Environment for 6 years for pollutant emissions and meteorological conditions (February 2010-December 2016). The results from the monitoring showed that the average annual NO2 concentration was 19.8066 ppb, compared to the monthly average of 17.34 ppb. The most recent monthly average was 1.358 ppb in July 2015 also the highest average of all months in all years in April, it was 23.638 ppb. The findings of the statistical review indicate that the annual NO2 average does not surpass the Jordanian ambient air quality limits allowed by the guidelines. The forecasted variability in the season shows that the level of NO2 was typically higher in winter than in summer, due to low temperatures, high average moisture and increasing NO2 sources which increase NO2 emissions. In order to understand the high NO2 concentrations at the residential site, environmental data have been analyzed (mainly wind and wind directions). The research has shown that the winds hit calm and south. This ensures that such winds do not disperse or minimize pollution but increase the concentration of pollutants. More than 77% of the wind is blowing at 0-5 m\s level. This wind blow contributes to the accumulation of its concentrations. There has been a negative association (r =-0.5217, p<0.001) between NO2 concentrations and wind speed. This situation shows that air pollution dilutes with dispersion when the wind speed is high. The negatively correlated between NO2 and wind direction (r= -0.6932, p<0.001) is also found. It may be clarified that the most commonly occurring wind path at the measurement site increases air pollution mitigation.

Subject: Potential Of Biochar Derived From Crop Residues In Soil Remediation And Controlling Air Pollution Due To Stubble Burning
Keywords: Biochar, Crop residues, Soil properties, Greenhouse gas, Climate change
Abstract: The burning of agricultural waste (stubble) in open fields (locally known as Parali) by the Indian farmers in Punjab, Haryana, Uttar Pradesh, Rajasthan, Madhya Pradesh and other nearby states during last four-five years has drawn attention of the Central and State Governments, Hon’ble Supreme Court of India and the National Green Tribunal (NGT) alongwith the common public because it is alleged to be one of the reasons for creating exceptionally high air pollution and smog in Delhi during months of September to November every year. One of the novel and feasible solutions to this problem may be converting the agro-waste into a useful product, biochar, which can be applied back to the fields for remediation of contaminated soil, improvement in soil properties as well as for reducing the entry of harmful gases into the environment. A novel method of producing biochar has been developed by the authors wherein the crop residues can be converted into biochar by an individual farmer on field itself without much investment and technical skills. Many researchers have studied the factors involved in the production and use of biochar for soil amendment; but in India, not much work has been carried out yet, as it is relatively a new concept in terms of using crop residues for biochar production. Therefore, in this paper, it has been tried to summarize the research done so far alongwith a critical assessment of various studies and their findings to help decide upon the future course of research and action, especially in Indian context where agricultural waste is produced in large quantities and its disposal creates environmental air pollution when burnt in open fields. There is a need to create awareness among the farmers about this novel approach of biochar production and application.

Subject: Comparison Of Effect Of Backwashing Methods On Overall Performance Of Rapid Sand Filter
Keywords: Partial backwashing, Filter resting, Extended terminal sub-fluidized wash, Ripening period, Filter run length, Performance indicator
Abstract: Almost all water treatment plants in India use sand filter to purify water. Air scouring followed by conventional back-washing of filter media is a common process followed. Recently, a huge amount of research is done across the world in the field of back-washing and its significance on the overall performance on a sand filter. As a part of performance optimization, investigation of the effect of various back-washing techniques on overall filtration cycle is of great significance. The objective of the research explained in this paper is to compare few recently developed backwashing methods, like partial backwashing, filter resting and extended terminal sub-fluidized wash with the conventional method of backwashing. The comparison is based on the parameters, like water requirement for backwashing, the effect on ripening period and succeeding length of filter run. This study was carried out in association with Ichalkaranji Municipal Council by installing a pilot scale model at Ichalkaranji municipal water treatment plant having a total capacity of 108 MLD (millions of litre per day). As it is very difficult to judge one particular method out of these four as every method has certain advantages and certain limitations, one common performance indicator is derived based on various factors of comparison. This performance indicator is quite easy to apply, flexible enough to modify as per need and age of water treatment plant.

Subject: Physico-Chemical And Bacteriological Profile Of Effluents Collected From Electroplating Industries
Keywords: Heavy metal contamination, Bioremediation, Electroplating industries, Electroplating effluents, Physico-chemical parameters, Bacteriological profile
Abstract: The present study was envisaged to the various physico-chemical and bacteriological properties of electroplating industrial effluents collected from GIDC estate of Vatva, Ahmedabad and GIDC estate of Kalol, kalol. The various parameters, like pH, total dissolved solid (TDS), total suspended solids (TSS), ammonical nitrogen, fluoride, chloride, sulphate, phosphate, chemical oxygen demand (COD), biochemical oxygen demand (BOD), hardness, calcium, magnesium, sodium, alkalinity as CaCO3, total organic carbon (TOC) alongwith heavy metals, namely zinc, copper, nickel, iron, cadmium, lead and chromium were tested from electroplating industrial effluents. The comparison of various parameters of the effluents with standards prescribed by the Central Pollution Control Board (CPCB), results perceived that pH of inlet effluents were lower than standard pH range. TSS values were within the standard range. Phosphate was found higher than prescribed standards. However, heavy metals, like copper, nickel, iron and chromium were also present in higher concentration and these metals are very much toxic for environment. Thus, the electroplating effluents are dreadfully polluting the environment and entail proper treatment before disposal. From bacteriological study total 57 isolates were isolated, 30 isolates from vatva GIDC electroplating industrial effluents and 27 isolates from kalol GIDC electroplating industrial effluents. Out of 57 isolates 10 were found Gram (-ve) and 47 were Gram (+ve). Out of total isolates, 47 were found motile and 10 were found non-motile in nature. These isolates were morphologically characterized; five isolates B2, B7, B8, B10 and B17 were found to be morphologically distinct. The isolates were also screened in different parameters of biochemical and environmental condition, namely salt concentrations and temperature. These indigenous isolates can be used as a bioremediation purpose for removing heavy metals from the industrial effluents. The bioremediation of heavy metals using microorganisms has received a great deal of attention in recent years, not only as a scientific novelty but also for its potential application in industry.

Subject: Assessing And Scoring The Corporate Sustainability Reports Of The Leading Indian Cement Companies Using GRI G4 Guidelines
Keywords: Sustainability, Sustainability reporting, Cement, GRI, Disclosure, Triple bottom line
Abstract: The global environmental and social issues have forced the corporate entities to pay attention to the social and environmental aspect of their business. Over the years, this concern witnessed a paradigm shift from traditional reporting of financial performance to non-financial performance as well. Majority of the companies utilize a comprehensive framework of the sustainability reporting in order to measure and disclose their non-financial performance based on the sustainability reporting guidelines. Sustainability reporting continues to be an evolving trend in India and is becoming a standard practise in order to compete with the global counterparts. This study aims to compare the sustainability reporting practices followed by big selected companies in the Indian cement industry. India is currently home to the world’s 2nd largest cement market, both in terms of production and consumption. Cement has a heavy environmental footprint as the production of cement releases CO2, as well as the production process consumes a lot of energy. Thus despite the popularity and profitability of the cement industry it is one of the highly polluting industries and contributes majorly to the global greenhouse gas emissions. In the backdrop of this, the current paper attempts to assess the sustainability performance of the leading companies in Indian cement industry and analyze their reporting trend on environmental, social and economic dimensions based on GRI G4 guidelines.

Keywords: Cheyyeru watershed, Water quality index, Landuse and land cover
Abstract: An experimental study on water quality index has been carried out to assess suitability of groundwater quality for drinking purposes in Cheyyeru watershed, YSR Kadapa district. This was done by subjecting groundwater samples from fourteen locations, to comprehensive physico-chemical analysis. Twelve parameters, namely pH, alkalinity, acidity, total hardness, calcium, magnesium, chlorides, nitrates, sulphates, electrical conductivity, total dissolved solids and bacteriological index have been considered for calculating the water quality index (WQI). The computed WQI shows that 15% of water samples fall in good quality category and 50% fall in moderate and rest in poor category which are not suitable for drinking purposes under normal conditions. High value of WQI is found due to the higher values of TDS, total hardness and sulphates. Factors influencing quality of groundwater were analyzed and found that improper landuse and land cover in the basin are the main contributing factors for poor quality of water.

Keywords: Freundlich adsorption isotherm, Halsey adsorption, Jovanovic adsorption isotherm, Regression coefficient, Biodegradable, nelumbo nucifera, Typha latifolia
Abstract: The present investigation explores the efficiency of low-cost agrowaste adsorbent for removal of octylphenolethoxylate surfactant from industrial wastewater. The stem of two aquatic weeds Nelumbo nucifera and Typha latifolia have been used as an adsorbent bed. They were named as non-carbonized nelumbo nucifera (A), carbonized nelumbo nucifera (B), non-carbonized Typha latifolia (C) and carbonized typha latifolia (D). Biosorption capacity of these adsorbent beds was analyzed by pH meter and UV-visible spectrophotometer. The efficiency of adsorption capacity of surfactant was validated by three adsorption isothermic models (Freundlich, Halsey and Jovanovic). The result show that regression coefficient (R2) values of Jovanovic adsorption isotherm from pH meter were 0.942, 0.986, 0.930, 0.972 and from UV-visible spectrophotometer were 0.979, 0.983, 0.969, 0.971 for the agrowaste A, B, C and D, respectively. These values are higher than the rest of the two isotherms. Adsorbent B showed higher values among all beds by both techniques. It indicates carbonized nelumbo nucifera has more potential to interact with molecules of surfactant than the rest. Particle size of agrowaste was analyzed by SEM images, it showed bed B was more porous than other beds. FTIR spectra indicate the presence of functional groups of alkaloids and flavonoids in the absorbent beds, which gives sites for adsorbtion of surfactants. Statistical analysis was done by single factor ANOVA considering significant value p=0.01. Thus, the removal of octylphenolethoxylate from the industrial wastewater maybe possible by the agrowaste, which is eco-friendly, chemical free and biodegradable in nature.

Abstract: The bench-scale experimental study aims in accelerating the vermicomposting process by modifying the conventional vermicomposting into engineered vermicomposting. The acceleration was done by enhancing the vermi environment and encourage the worms to participate actively in the digestion process. The engineered process composes of pre-processing the waste and augmenting air artificially with airflow rate of 0.62 L/min in the Vermibin. The aeration was done in vertically elevated Vermibin with five different airflow durations (2 hr, 4 hr, 6 hr, 8 hr and 10 hr) by naming the bin as A1, A2, A3, A4 and A5, respectively. The optimum airflow duration was identified based on the substrate volume reduction and biomass growth in the Vermibin. In parallel, the nutrient status of vermicast also assessed, in order to characterize the vermicast generated in the reactors. Results reveal that 4 hr aeration with airflow rate of 0.67 L/min performance better and provide suitable environment for vermicomposting process.

Keywords: Statistical analyses, Microbiological and physico-chemical pollution, Oued Larbaa and its tributaries, Northern Morocco
Abstract: The objective of this study is to study the spatio-temporal dynamics of different bacterial populations of faecal origin (total aerobic mesophilic flora, faecal coliforms, total coliforms, faecal Streptococci and sulphite-reducing anaerobes) as a function of physico-chemical variables at the level of the Oued Larbaa and its tributaries. In order to illustrate the impact of physico-chemical parameters on the distribution of bacterial flora in this aquatic ecosystem, a multi-dimensional statistical study using principal component analysis (PCA) in combination with hierarchical ascending classification (HAC) was carried out during two different environmental conditions (summer and rainy season). Our results showed that the distribution of faecal microorganisms in the environment is most often influenced by environmental factors in the receiving environment, in particular biodegradable organic matter, dissolved oxygen, suspended solids, pH, temperature, as well as parameters indicative of water mineralization in terms of electrical conductivity, salinity, dry residues and total dissolved solids. These correlations established between bacterial loads and environmental factors significantly control the survival of these bacteria, which become more or less adapted to these environmental changes and maybe the cause of possible infection. This variation in the level of bacterial contamination is further accentuated by the input of raw domestic wastewater discharges and the practice of market gardening on the banks of this ecosystem, which is very much frequented by livestock and domestic animals.

Abstract: The emergence of severe acute respiratory syndrome coronavirus 2 in late December 2019 has led to the global outbreak of coronavirus disease (COVID-19). Due to its large infectivity and transmissibility, the spread of COVID-19 has put lives and livelihoods at risk. Even though the COVID-19 global outbreak has been termed a defining event, the wider implications have been felt for a longer period. In recent decades, there have been growing concerns within the health and environmental sectors due to climate emergency. Noticeably, there has been a marked increase in the frequency of extreme events, zoonotic diseases and climate-related disasters, posing a substantial threat to society while pushing them beyond their carrying capacity. Thus, the ongoing pandemic and climate crisis may have a tenuous causal association. Conversely, the outbreak has also emanated multiple positive environmental manifestations. The pandemic has resulted in cleaner air and water, alongwith a significant reduction in the emission levels while allowing wildlife and biodiversity to bounce back. The current study aims to assess the immediate and short-term effects of the pandemic while forecasting the medium and long-term impact on the global environment. The study explores the possibility of adopting a global blueprint using the concept of one health and planetary health for long-term sustainability. This study can be a great help for environmental scientists, policymakers and climate professionals to formulate environment responsive climate action plans in a post-pandemic world.

Subject: Assessment Of Toxicity Of Marine Sediment And Aromatic Hydrocarbon Samples Using Marine Algal Toxicity And Phytotoxicity Tests
Keywords: Acute toxicity, Phaeodactylum tricornutum, Aromatic hydrocarbons, Sinapsis alba, Marine sediment
Abstract: The aim of this study is to assess the toxicity of marine sediment and representative aromatic hydrocarbon samples on the growth of microalga Phaeodactylum tricornutum and the seed of Sinapsis alba. The methods employed for the toxicological evaluation involve physico-chemical analysis of the marine sediment, marine algal toxicity test using microalga Phaeodactylum tricornutum and phytotoxicity testing using Sinapsis alba (mustard seed). The results showed that both Abonema and Nembe waterside sediment samples had higher fractions of physico–chemical parameters than Onne sampled locations. Marine algal toxicity testing revealed that the positive control (K2Cr2O7) had the highest EC50 value of 8.07±0.03 mg/L with CV and r2 values of 68.61% and 0.99 while pyrene Nembe sediment had the least EC50 value of 4.63±0.01 mg/L with CV and r2 values of 78.27% and 0.98 with very strong significant positive linear relationship between an algal number and sample concentrations (P<0.05). The phytotoxicity testing also showed that the most inhibitory effect was produced by pyrene + Onne sediment sample with GI and CV values of 7.14±0.023% and 0.37% while the least inhibitory effect was produced by xylene + distilled water sample with GI and CV values of 28.57±0.03% and 0.18%. These observations revealed aquatic and terrestrial toxicity potentials of these test samples and prompt measures should be deployed to abate their menace in the Rivers State marine environment.
