Subject: Effect Of Anthropogenic Activities On The Water Quality Of Community Pond In Keshpur Block Of Paschim Medinipur – A Survey Report
Keywords: Potability, community pond water, Keshpur block, Paschim Medinipur, West Bengal
Abstract: During the survey of potability of water (2017-2019) in Keshpur block, Paschim Medinipur, West Bengal, it has been noted that the local inhabitants of the area regularly use pond as source of water for bathing of human and domestic animals, washing clothes, utensils, vegetables and other materials; watering livestock, also used in some cases for domestic and worship purposes too. The present work deals with the study of water quality standards by analyzing the viable coliform alongwith other water borne bacteria present in water samples collected from ten randomly chosen major community ponds of Keshpur block in Paschim Medinipur district, West Bengal. This preliminary study may provide some important information about potential public health risks associated with the use of ponds water in the highly populated area, possible source of contamination, like cow dung, vermicompost and poultry litter. In this paper, we review the bacterial composition of cattle manure, poultry litter as well as methods engaged in the control of pathogenic microbes present in manure and recommendations that need to be respected and implemented in order to prevent microbial contamination of the environment, animals and humans.

Abstract: The municipal solid waste generated in urban areas is creating a severe environmental problem in absence of its proper handling and management. This paper is based on a study related to municipal solid waste management, seasonal variation in waste generation from residential households, total waste generated per day, constituents of solid waste and the potential of waste to energy in Alwar city of Rajasthan. The study has been conducted for more than one year period from May 2018 to May 2019 so as to study the effect of seasonal variation in waste generation including all the seasons of a year. The study area consisted of the whole urban area of Alwar city comprising municipal corporation boundary and it was divided into four zones for the ease of investigation. Each zone of the study area comprised of residential areas. From each zone, 30 samples were collected in a period of three months. The samples were analyzed for their composition and seasonal variation. During the study, the calorific values of the waste material have also been calculated after segregation of reusable and recyclable material and on the same way, analysis of the potential of waste to energy has been carried out. The study indicates that there is an immediate need for proper monitoring at the level of the government to take steps towards segregation, collection, transportation, treatment and disposal of solid waste as per the latest municipal solid waste (management and handling) rules, 2016. Alwar city has a good potential of waste to energy as much as 2.27 Mw and the electricity generated can be utilized either for revenue realization or for electrification in the city by the local body administration of the city.

Subject: Study Of Physico-Chemical Quality Of Groundwater In Tyikomiyne Region Of Community Of Talssint (Eastern Morocco), By Application Of Principal Component Analysis
Keywords: Spring waters, Talssint, Principal component analysis, major elements of pollution
Abstract: For the purpose of the management and conservation of the aquatic environment of spring waters in the Tykomyine-Talssint region of eastern Morocco, principal component analysis (PCA) of physico-chemical parameters and major elements were studied during the low-water period (May of the year 2011). The visualization of the results allowed us to show that the pH, T°, SO42-, Ca2+, Mg2+, K+, Na+ and conductivity are positively correlated with the F1 axis, contrary to the ions: NO3–, Cl– which is associated negatively on the two main axes F1 and F2. Thus the application of the principal component analysis on these results shows that we have two groups of stations: the first group of stations in the positive part of the F1 axis, characterized by waters with high concentrations in pH, T°, SO42-, Ca2+, Mg2+, K+, Na+ and conductivity at the S1 and S5 stations. The second group of stations in the negative part of the F1 axis, characterized by waters with a high concentration of Cl–, NO3– at the station S2. This enrichment in major elements is to be related to the geological context of the studied region.

Subject: COVID-19 Lockdown : A Blessing Or Blight For Wildlife?
Keywords: COVID-19, Lockdown, Wildlife protection, Environmental conservation, Impacts of COVID-19
Abstract: This research aims to show the positive and negative impacts of COVID-19 lockdown on wildlife. The study shows that since the lockdown came into effect, there have been improvements in environmental conditions, the resurgence of marine life in coastal waters and privacy for wildlife. On the other hand, the lockdown has also bought some negative impacts, such as increasing in poaching activities, human-wildlife conflicts, hunger issues for urban wildlife and the reopening of wet markets. The study also provides solutions to keep the wildlife safe during and after the lockdown period, such as the use of technology to monitor unauthorized human movements in wildlife parks, providing economic assistance to keep villagers away from wildlife poaching and use of carbon credits to ensure the continued flow of revenue during a time like these. There is a chance that once the lockdown is lifted, all global activities will return and people will go back to their old ways and all the positive impacts of the lockdown will disappear. Hopefully, the current situation will facilitate us to reconsider our way of life and our relationship with nature and encourage us to make the necessary changes that are long pending.

Keywords: Groundwater, physico-chemical parameters, hydrochemical facies, hydrolysis, salinity hazard
Abstract: Groundwaters undergo changes in their chemistry and quality as they pass through rocks, soils and human settlement areas. The modification is manifested in variations in their cation and anion constituents. Attempt has been made to classify groundwater on the basis of their chemistry, the sources of the major ions and to categorize quality of groundwater for irrigation purposes. The physical parameters, such as pH (7.5 average 8.5), EC (400-3268 mmhos/cm) and TDS (1166-2451.25 mg/L) found to be higher in groundwater samples near the sugar factories. Average values of cations and anions were in the order of Ca (107.04 mg/L), Na (67.46 mg/L), Mg (61.31 mg/L), K (11.44 mg/L) and Cl (245.38 mg/L), HCO3 (192.50 mg/L), SO4 (59.51 mg/L), respectively. Average sodium adsorption ratio (SAR) was 1.35. Calcium – magnesium, cation hydrochemical facies is most dominant with 92% followed by 8% of sodium – calcium facies. Anion hydrochemical facies is dominated by chloride – sulphate – bicarbonate facies (65.39%), bicarbonate – chloride – sulphate facies (19.23%) and chloride – sulphate facies (15.38%). The dominance of calcium – sodium facies can be attributed to the leaching or ion-exchange reactions. Because of medium to high salinity hazard ground water is by and large suitable to moderate to high salt tolerant crops demanding for reclamation of soil for better agriculture yield.

Subject: Impact Of Pre-monsoon Cyclonic Storm Fani Along The Coastal Tract Of Odisha : A Geospatial Assessment
Keywords: Cyclone, Fani, Odisha, Chilika, Shoreline, Pre-monsoon
Abstract: The coastal tract of Odisha along the Indian east coast witnessed a rare pre-monsoon severe cyclonic storm Fani on 3rd May 2019. The storm was unique with respect to its timing, strength and trajectory wherein contrary to normal observations, it intensified to a category – 4 cyclones from a tropical depression as it approached the Indian subcontinent. Current research findings portray the impact being catastrophic taking away 64 lives and opening up 4 new mouths along the largest lagoon of Asia, the Chilika. The study indicates noteworthy erosional and accretion activity along the shoreline. These changes are going to affect the sensitive coastal ecosystem of Chilika lagoon due to saline water transgression. Hence, it is suggested that better preparedness, adequate beefed-up infrastructure as well as eco-sensitive measures, such as cyclone-resistant plantations should be given a thrust for sustainable management of this susceptible coastal tract.

Abstract: Drivers are exposed to significant amounts of health-damaging air pollutants. The aim of the present investigation was to study the risk of respiratory disorders among professional bus drivers. This case-control study was carried out on 170 bus drivers and 94 control groups. Work history, respiratory symptoms, smoking habit, etc., were recorded. Lung function parameters of the participants were determined by a portable spirometer. The pulmonary parameters of bus drivers were significantly lower than those of controls. Lung function indices of the drivers decline with an increase of duration of exposure. A significant decline in lung function parameter was observed among smokers compared to non-smokers. The prevalence of different respiratory symptoms among bus drivers was significantly higher than that of control participants. The risks of restrictive and chronic obstructive pulmonary disorders among bus drivers were 9.31 times and 2.83 times higher than that of control participants, respectively. The likelihood of having a dry cough, productive cough, chest tightness, dyspnea and chest pain were significantly higher among bus drivers than the controls. The present study revealed that exposure to vehicle emissions leads to a significant risk of different pulmonary disorder among professional drivers. Driving with a smoking habit can be termed as a dreadful combination with respect to pulmonary health.

Subject: Methyl Geranate: A Novel Quorum Quencher As An Anticorrosion Agent To Prevent Metal Biocorrosion
Keywords: Biofilm, Biocorrosion, Quorum sensing, Quorum quenching, Methyl geranate
Abstract: Microbial colonization causes damage to the integrity of metal surfaces which lead to microbiologically influenced corrosion (MIC). Consequently, it becomes a serious problem for aquatic and marine industries globally. Despite the availability of biocides to control corrosion, most of them are ineffective due to its toxicity. Hence, to address the problems with toxic biocides, in the present study, the anticorrosion activity of a quorum quencher molecule methyl geranate (MG) known to interfere with bacterial signaling was investigated. Experimental stainless steel (SS-316) coupons were submerged in pond water for 10-30 days in the laboratory. Biocorrosion was evaluated by determining the structure of the biofilm covered on stainless steel (SS 316) coupons submerged in pond water by scanning electron microscopy (SEM), confocal laser scanning microscopy (CLSM) and fluorescence microscopy imaging of the coupon surface. Adding up, MG significantly reduced the secretion of biofilm EPS by 57% without affecting the bacterial growth. MG treated stainless steel coupons indicated the reduced oxygen reduction current at the metal surface as evident from applied electrode potential measurements which was associated with significant changes in the composition of bacterial biofilms on the steel surfaces. These results demonstrate the potential of the quorum quencher MG to prevent biocorrosion on metal surface.

Subject: Adsorption of wastewater using green nanoparticles synthesiszed from Murraya Koenigii and Coariandrum sativum
Keywords: Wastewater, Nanoparticles, Curry leaves, Coriander leaves, FTIR, Adsorption
Abstract: Nanoparticles are usually synthesized from metals, such as silver, gold, platinum, copper and zinc. There are several methods used for the synthesis of nanoparticles, such as physical, chemical and biological. People all over the world use different kinds of personal care products (PCPs), like soaps, sunscreen lotions, hair styling products, hair removers, shampoos, conditioners, moisturizers, anti-agers, nail and cuticle care products, oral care including toothpaste and whiteners. Curry leaves are part of a regular diet in India and many parts of the world, it may also serve as a possible nutritional intervention and the extract itself or fractions obtained there from may be used also as a future nutritional supplement to combat oxidative stress-induced tissue damage in the people exposed to lead. Plant mediated synthesis of silver nanoparticles and the study of their size and properties are of fundamental importance in the advancement of recent research. The size and shape of the nanoparticles form a basis for the wide variety of applications. In the present study, biosynthesis and characterization (UV-visible spectroscopy and FTIR) of green nanoparticles from aqueous extract of curry leaves (Murraya Koenigii) and coriander leaves (Coriandrum sativum) was performed and the same was subjected to adsorption studies for wastewater treatment to find out the optimum pH, dosage and time of action for effective removal. The initial absorbance value of household wastewater was 0.788. After treating with zinc nanoparticle synthesised from curry and coriander leaf extract was found to be 0.422 and 0.615, respectively. In this, Murraya koenigii (curry leaves) proves more efficient for treating household wastewater.

Keywords: Solid waste management, Biological problems, physico-chemical problems, Hazardous wastes
Abstract: Collecting, treating and disposing of a discarded solid material is called solid waste management. Wastes heap up causing problems due to improper waste disposal systems by waste management teams. Biological and physico-chemical problems are caused to the environment due to the solid wastes from companies, like toxic metals, hazardous wastes and chemicals. When hazardous wastes, like pesticides, batteries containing lead, mercury or zinc, e-waste and plastics are mixed up with paper and other scraps, dioxins are produced and causes various diseases like cancer. The hazardous wastes usually mix up with other ordinary garbage and flammable wastes while amassing solid waste thus these results in the risky disposal process. Another waste management method is proposed in Coimbatore City Municipal Corporation as a case study for the reduction of solid waste at compost yard.

Subject: Case Study And Analysis Of Water Supply System For Pillur Water Supply Improvement Scheme’s Area
Keywords: Water supply, Water treatment, Pillur, Bhavani river
Abstract: Sufficient water of appropriate quality and quantity has been one of the most important issues in human history. People began to transport water from other locations to their communities. A water supply system consists of infrastructure that collects, treats, stores and distributes water between water sources and consumers. This project concerns the design of urban and rural water distribution system in Coimbatore and Tiruppur districts. Sedimentation, aeration, filtration, chlorination of raw water is the main treatment in the collection of raw water from Pillur reservoir through Headworks. Clear water pumping main and distribution of treated water to the public is ensured.

Subject: Repair And Rehabilitation Of Amaravathy Dam In Tiruppur District: Case Study
Keywords: Amaravathy dam, Repair and rehabilitation of dam structure, Seepage, Reaming, Epoxy coating
Abstract: Irrigation is the backbone of the Indian economy which is the cornerstone in Tamil Nadu agriculture development on which the livelihood of more than 60% of the population is depending on it. In Tiruppur district, Tamil Nadu, Amaravathy Dam was constructed across the Amaravathy river during the year 1953-58 for the benefit of irrigating the 22116 ha of irrigation land and basic domestic water needs in Tiruppur and Karur district. Amaravathy Dam is a composite structure made with both earthern type and masonry types dam. The dam was in service for the past 7 decades. So, the dam has been affected by seepage water through dam structures. Rehabilitation of structures in dam components is the need of the hour. Seepage is the main problem in the masonry portion of this dam and chokage in drainage systems. Repairing or rehabilitating the dam structure will enhance the life and durability of the structure. Reconstruction of chute and toe drains is also considered as effective. In this article, detailed study has been carried out to control the seepage and chokage problems in the dam structure, methods, like reaming, epoxy coating and injection grouting are followed.
