Keywords: Polyethylenase, Plastic biodegradation, Polyethylene terephthalate, Microbial degradation, Esterase
Abstract: Plastics have been a huge nuisance to the world. In order to degrade the most widely used polyethylene terephthalate (PET), this research has been conducted. Organisms were isolated using minimal media along with shredded PET plastic provided as the sole carbon source. Eight individual colonies were isolated and were named PET1 to PET8. Organisms were identified by Gram staining and biochemical assays. Thin layer chromatography was performed along with standard to check the presence of terephthalic acid produced as a result of PET degradation. High pressure liquid chromatography was performed to confirm the production of terephthalic acid. A colourimetric assay was standardized using bromocresol green to quantitatively measure the terephthalic acid produced following the degradation of the plastic. Lowry’s method was performed to check the presence of protein. Since the enzyme is the only protein available in the media it is a confirmatory test used to check the presence of the enzyme. PETase theoretically being an esterase should utilize tributyrin as a substrate. Hence esterase activity was viewed by well diffusion method on tributyrin agar. A colourimetric assay was standardized using p-nitrophenyl acetate to analyze the amount of PETase produced by the organisms. The temperature, pH, shaking and static conditions were standardized and optimum characteristics for the production of the enzyme were determined. The highest producers were given for 16s rRNA sequencing. The weight of the plastic was determined before and after the degradation. The surface of the plastic was studied using scanning electron microscopy. The enzyme was purified and sodium dodecyl sulphate polyacrylamide gel electrophoresis was performed. Plasmids were isolated and then transformation was carried out into E. coli DH5a. This analysis is the need of the hour and further the enzyme activity can be studied and the enzymes can be used to treat the plastic filled dump yards.

Subject: Removal Of Cutting Oil From Wastewater Through Novel Adsorbents Developed From Waste Coconut Fibres
Keywords: oily wastewater, Adsorbents, adsorption equilibrium, kinetics, thermodynamics
Abstract: Oil contained wastewater discharged into the environment poses a serious threat. Removal of oil from wastewater is difficult mostly when the oil is present in a stable oil-in-water emulsion. Adsorption has emerged as a cost-effective technique due to the recent trend of developing adsorbents from agro-waste. This research focuses on developing novel adsorbents from waste coconut fibre in untreated raw coconut fibre (UCF), acid-alkali treated coconut fibre (ACF) and carbonized coconut fibre (CCF) form and comparatively evaluate the impact on oil adsorption capacity on these adsorbents developed through chemical and thermal treatment. Batch experiments were conducted to understand the influence of important operation parameter, namely pH (2-10), time of contact (10-150 min), adsorbent dose (0.5-7.5 g/L) and initial oil concentration (100-2000 mg/L). On comparison of equilibrium study, it revealed that thermo-chemically treated fibres (CCF) have higher adsorption capacity (16.22 mg/g) than chemically treated (8.81 mg/g) and raw coconut fibres (6.82 mg/g) and the present adsorption process fits Freundlich isotherm. The kinetic study indicates that it follows a pseudo-second-order kinetic model for UCF, ACF and CCF. Thermodynamically the process is endothermic and enthalpy value for CCF is 38.11 KJ/mol, ACF is 17.73 KJ/mol and UCF is 15.5 KJ/mol.

Keywords: pan evaporation, artificial neural network, climate change, environmental modelling, water resour-ces
Abstract: Evaporation, as a key process in the earth’s ecosystems, is a key factor in water resources and hydrometeorological research. Avoiding the expensive evaporation prediction methods, the pan evaporation technique is one of the most widely used and accepted methods. In this study, a multilayer neural network tool (ANN) and a multivariate non-linear regression technique (MNLR) are utilized to estimate the daily and monthly pan evaporation in the arid environment of Kuwait. Estimation results are compared to two empirical methods, the Cuenca and Christiansen models, employing the so-called combination method FAO-56 PM for the same raw data and input variables, daily average air temperature, wind speed, relative humidity and solar radiation. Cross-validation, 10-folds for the daily time scale and 5-folds for the monthly time scale, procedures are implemented to examine the model’s reliability and consistency. Evaluation metrics, like RMSE, R, MAE and NSE are applied to assess model performance. In general, it is demonstrated that the ANN model outperforms the MNLR model, however, the standard deviation among the cross-validated k-folds of the MNLR is lower than that of the ANN model. The monthly performance outperformed the daily output by achieving better statistical indicators with R=0.9084, 0.9092, 0.8961 and 0.9002 than the daily ANN, monthly ANN, daily MNLR and monthly MNLR models, respectively.

Subject: A Review On Fluoride Concentration In Groundwater From Industrial Cluster – Hard Rock Aquifers Of Tiruppur Taluk
Keywords: Fluorides, Hard rock, Spatial distribution, Correlation, Tiruppur taluk, Tamil Nadu
Abstract: The intent of the present study is to comprehend the geochemical processes of fluorides in groundwater from Tiruppur taluk of Tiruppur district, Tamil Nadu, India. Geologically, the region has base rocks of Archaean group of charnockite, hornblende biotite gneiss, pink granite, anorthosite and amphibolites. Outstanding fluorides (F–) in groundwater were observed in semi-arid of hard rock areas. This study result posits the groundwater is characterized by sodium (Na+): bicarbonate (HCO3–) facies. The fluorides of study environ vary from 0.12-2.34 mg/L with an average of 1.2 mg/L. Since the total samples collected 30% of fluoride indicates fluoride concentration surpasses the maximum allowable limit of 1.5 mg/L. This study suggests spatial variation noticed in fluoride substance emerge due to fluoride bearing minerals, grade of weathering of rocks, contact interval of aquifer material with water and the related geochemical process. A correlation attempted has been made between the fluoride concentrations with water type, the relationship of fluoride with HCO3–, fluoride with Na+ and pH (parts of hydrogen) were studied and proves that HCO3– has a better correlation with fluoride than the other parameters. The weathering of rocks causes the release of Na+ and HCO3– ions, which controls the water chemistry by strong acid by intensive ion exchange. Hence this correlation reveals Na+, Cl– (chloride) and Mg2+ (magnesium) ions play a vital role in controlling water chemistry of this area.

Keywords: Biological oxygen demand, Dissolved oxygen, Chemical oxygen demand, pH, Total dissolved solids, Temperature, Linear regression, Multivariate linear regression model
Abstract: Water samples were collected from 20 stations of the Godwar region where human and animal activities were elevated. Multiple samples were analyzed for dissolved oxygen (DO), biochemical oxygen demand (BOD), chemical oxygen demand (COD), pH, total dissolved solids (TDS) and temperature (Temp.). The total data points were used to ascertain relationships between the parameters and data were also subjected to statistical analysis. First, a linear regression model was established between DO/BOD, COD/DO, BOD/COD, COD/pH, BOD/pH and DO/pH. A high to moderate correlation coefficient was observed as R2 ranged from 0.889 to 0.034 for these parameters. Then a multivariate linear regression model was setup for BOD and COD as dependent variables and DO, Temp., TDS and pH as four independent variables. The performance of the multivariate linear regression model was justified with statistical variables like average square root error (ASRE) and universal efficiency (UE). The predicted value of BOD and COD by model and regression analysis was in close agreement with their respective measured value. It was found that the pH parameter has more effect on BOD and COD as compared to predicting another parameter. ASRE was 37.8 mg/L for BOD prediction and 79.6 mg/L for COD prediction in a multivariate linear regression model.

Keywords: Nutrient additions, Vellode lake, Sediment, Bird density
Abstract: A multiplicity of floral and faunal species is an inimitable feature of tropical freshwater lakes. Preservation of the tropical lakes by an understanding of the process is a conservation action for numerous biotic species. Various studies reported that the accumulation of nutrients has been considered as a foremost menace of the inimitable tropical lakes due to bottom sediment and dominant biotic groups. However, the course of action is not clearly established. The study was conducted at Vellode lake, Erode district, that lies between 1108’04.04″ N and 77037’52.42″ E, South India. Characterization of water and sediment analysis was conducted to measure the seasonal changes and variations. The bird populations were surveyed with the assistance of field guides and lake managers. The correlation between the chemical features of the lake sediment and water was calculated. Correlation analysis between biodiversity indices of bird populations (independent) and water quality index (dependent) was calculated to find the impact of bird populations on the water quality of the lake. Role of bottom sediment on the hydrology of the lake, impact of bird droppings on hydrology and seasonal influence on the nutrient additions was tinted. Current research revealed that the high volume of bottom sediment and density of aquatic birds were identified as the major factors for the depletion of water eminence. Based on the annotations appropriate strategies are recommended to manage base sediment by engineering, chemical and physical methods and cultural techniques for other components responsible for the deterioration of the tropical lake quality.

Keywords: Biosorption, Zinc(II), Chlorella, Volvox, Zygnema
Abstract: The heavy metals discharged into the water bodies are toxic to human beings and other life forms even at low concentrations. Biosorption of heavy metals using dried algal biomass can be an effective process for the removal of zinc ions from industrial wastewater. In this study, the batch removal of zinc ions from electroplating industrial wastewater using dried green algal species (Chlorella, Volvox and Zygnema) are investigated. The zinc uptake by biosorbents was dependent on the contact time, sorbent dosage, initial pH and the initial zinc ion concentration. Langmuir and Freundlich isotherm models were fitted with the equilibrium data. The maximum zinc removal efficiency was found to be 84.7, 79.0 and 69.8% for Chlorella, Volvox and Zygnema, respectively. The zinc uptakes by the three algal species were best described by the Freundlich isotherm model. This study verified the possibility of using green algal species Chlorella, Volvox and Zygnema as valuable biosorbent materials for the removal of zinc from industrial wastewater.

Abstract: Plastic is used as a polymer substitute for natural materials. It has become an essential aspect of our lives and there was a considerable intensification in the production of plastic in the last few decades. This research aims to evaluate the possibility of using granulated plastic waste material to partially substitute for the fine aggregate in the concrete specimen. In this M30 grade, concrete design strength of mix ratio of 1:1.3:2.44 and 0.42 w/c ratio were used. Five different percentages (0%, 10%, 20%, 30%, 40%) of recycled polypropylene plastic granules waste were used to replace the fine aggregate and in addition to this GI wire fibre, 2% by weight of concrete was added to improve the mechanical properties of concrete. GI wire fibre can be used as a low-cost alternative to steel fibre in concrete. The physical properties test was conducted on cement, fine aggregate, coarse aggregate and plastic granules. The workability and density were improved by the addition of plastic granules. The compressive and split tensile strengths for the specimens were determined to find the optimum percentage of recycled polypropylene plastic (PP) granules. The test result revealed that the compressive strength increases upto 20% and tensile strength were increased by 10% compared to the normal concrete.

Keywords: E-waste, Asia Pacific, Recycling, Resource recovery, Extended producer responsibility, Public-private partnerships
Abstract: Sound management of used electrical and electronic equipment (EEE), known as e-waste, is generated at a higher rate than most other waste streams in many countries. According to the United Nations, the world produced 53 million metric tonnes (Mt) of e-waste in 2019, mostly from the Asian region. E-waste contains many toxic compounds, poorly managed could cause severe environmental and human health issues. E-waste also contains valuable metals for resource recovery. Environmentally sound management (ESM) of e-waste is inadequate in many developing countries due to a lack of financial resources, infrastructure and the informal recycling sector’s dominance. Many countries have been developing regulations based on extended producer responsibility (EPR) concepts. This paper aims to review the business and economic potential of e-waste resource recovery in the Asia Pacific countries.

Abstract: p,p’-DDT (1,1,1-trichloro-2,2-bis(4-chlorophenyl) ethane is a colourless, odourless organochlorine insecticide. WHO recom-mends DDT as an indoor spray for controlling malaria as a part of integrated vector management. At present, in India, DDT is banned for agricultural purposes but is still used for controlling vector-borne diseases. Widespread and reckless use of DDT caused considerable harm to the wildlife population. In this study, removal of p,p’-DDT from an aqueous system was carried out with four different natural adsorbents. The natural adsorbents employed for the adsorption studies are granular activated carbon, powdered activated carbon, chitosan and carbon-coated chitosan film. The adsorption capacity for the natural adsorbents is in the order of powdered activated carbon (irrespective of pH) (99.63%) > chitosan at pH 7 (95.18%) > granular activated carbon at pH 7 (89.18) > carbon-coated chitosan film at pH 11 (88.3).

Subject: Exposure Assessment Of Respirable Dust For Opencast Limestone Mine In India
Keywords: Respirable dust, Crystalline silica, Limestone, Mine regulation
Abstract: Respirable dust is harmful to human beings and can cause silicosis, bronchitis, respiratory problems especially miners all over the world depending upon their concentration, percentage of crystalline silica, nature of the respirable dust and exposure time. The objective of the paper is to assess the exposure of dust and crystalline silica generated during the opencast limestone mine as per the Director General Mining Safety (DGMS). Sidekick 51 MTX gravimetric dust sampler (GDS), UK, approved by Director General of Mines Safety (DGMS), was utilised for personal dust exposure assessment of limestone miners. The presence of crystalline silica was determined by FTIR using Opus software and followed the NIOSH-7602 methodology. A total of 54 airborne respirable dust samples (29 personal dust and 25 area dust samples) were collected from May 2016 to May 2018. It was observed that 8 hr time weighted average (TWA) concentration of airborne respirable dust at all sampled locations of opencast limestone mines were within the permissible limit (that is 3 mg/m3) as prescribed under Regulation 124 of Metalliferous Mines Regulation 1961. 31 dust samples analyzed for crystalline silica (SiO2) content were below 5% except for one sample near the hopper area was below the permissible limit.

Subject: Investigation Of The Efficacy Of Water Hyacinth (Aquatic Plant) For The Treatment Of Dairy Effluent
Keywords: Water hyacinth, Aquatic plants, Adsorption, Industrial wastewater, Biological treatment
Abstract: The disposal of wastewater is one of the most serious problems in the industrial era of the urbanizing world. It affects the quality of land, water and also its surrounding environment significantly. The present study focused on the cost-effective biological treatment of dairy effluent by using aquatic plant (water hyacinth). The major objective of our study is to investigate the filtration potential of water hyacinth (an aquatic plant) in treating wastewater, that is discharged from the small-scale dairy industries. The water quality parameters, such as pH, electrical conductivity (EC), total hardness (TH), alkalinity, total dissolved solids (TDS), chemical oxygen demand (COD), calcium (Ca), magnesium (Mg), sulphate, potassium, sodium and chloride, were tested for the detention period of 15 days and 30 days with varying plant growth density. The results were analyzed and compared with the irrigation standards to evaluate the treatment efficiency. The analysis results show greater efficiency in removal of TH, Ca, Mg, EC and COD as 80, 85, 64, 63 and 73%, respectively and moderate efficiency in removal of Na, K and SO4 as 43, 57 and 59%, respectively. Thus, the present biological treatment system will provide outlet water of upgraded quality by considering the efficient removal of COD, TH, Na, K and SO4 that can be discharged directly into the public drains and watercourses without affecting the assimilating capacity of streams. The present study can be continued to analyze the various aquatic plants in order to construct artificial wetland based treatment facilities for uptaking the pollutants from wastewater that can be used for secondary uses, such as gardening and landscaping purposes.

Subject: Assessment And Characterization Of Water Quality Of Imphal River Using Hydrogeochemical And Multivariate Methods, Manipur
Keywords: Hydrochemistry, Multivariate analysis, Water quality index, Ecohydrology, Irrigational water, Urban runoff, Sewage disposal
Abstract: Water quality and hydrogeochemical assessment of Imphal river water within Imphal city were carried out for pre-monsoon and post-monsoon seasons. Significant downstream variations in water quality parameters were observed for pH, temperature, EC, oxidation reduction potential (ORP), turbidity, total hardness, DO, NO3–, PO43-, SO42- and more distinct changes were observed during the post-monsoon season. Geochemical evaluation indicates Na+-K+-Cl–-HCO3– and Na+-K+-Cl–-HCO3–-SO42- type of water during pre-monsoon and post-monsoon, respectively. Statistical investigation indicates the factors controlling the Imphal river water quality as well as identifies the source of variation among the samples. Factor analyses were carried out for 4 factors that account for around 82.34% and 77.79% of the variability of the data during pre-monsoon and post-monsoon, respectively. Irrigation water quality was evaluated using an irrigational water quality index that exhibits overall satisfactory to good quality water.
