Abstract: This study is based on the quality of wastewater from Hawassa University surroundings, which was assessed to determine its suitability for irrigation purposes. Grab samples of influent and the treated water was taken for assessing quality parameters. The study revealed that the treated water could be used for irrigation purposes with some moderate restrictions. Even though EC and TDS permit to irrigate fruit trees and fodder crops, there is a risk of soil degradation due to the high value of SAR. Results also indicated that carbonate, potassium and phosphate exceeded the specified limits for wastewater reuse in agriculture. Despite increased nutritive elements, continuous use of treated sewage water for irrigation will make the soil acidic. Analysis of soil parameters indicated that there is an increase in nitrogen, phosphate and potassium nutrient levels considerably to benefit crop production but an increase in soil EC is a serious concern.

Subject: Design and Eco-utilization of Blast Furnace Slag Generated from Rourkela Steel Plant by using Statistical Analysis at Odisha
Keywords: Blast furnace slag, Water absorption capacity, Compressive strength, Eco-utilization
Abstract: In this work, we developed brick by using the granulated blast furnace (BF) slag produced from the Rourkela Steel Plant with lime and sand. Two types of bricks are developed; one is the mixture of granulated BF-slag and lime whereas the other one is a mixture of granulated BF slag, sand and lime. The volume and weight were measured and the bricks were characterized by compressive strength, water absorption capacity and efflorescence testing. From the experiments and analyzed data, it was found that for M-4 sample of lime-slag brick having composition of 20% lime and 80% slag, the compressive strength is the maximum and water absorption (%) is minimum, whereas in the case of lime-sand-slag brick the compressive strength is the maximum at M-6 sample having composition 30% lime, 30% slag and 40% sand whereas water absorption is minimum at M-4 sample having composition 20% lime, 20% slag and 60% sand. The efflorescence test shows that no soluble salts were dispersed over the tested brick indicating a high quality of brick relative to conventional bricks. Hence, from the analyzed data, we conclude that the brick developed with 20% lime and 80% slag is better in quality than the conventionally manufactured bricks.

Subject: Metabolic Responses of Agricultural Soil Bacteria to Glyphosate and Paraquat
Keywords: Bacterial physiology, Tolerance, Herbicides, Bacteria strains, Bacterial adaptation
Abstract: Much of the scientific literature and the lay community consider that the herbicides are specific against the weeds in the agricultural system, however, their application in the soil can affect the bacterial population deleteriously. The toxic effect of herbicides on non-target microorganisms may influence the degradation of organic matter resulting in changes to nutrient cycling. There is, therefore, a need to obtain data on how herbicides physiologically affect agricultural soil microbiota. In the present study, different strains of bacteria incubated in media containing different concentrations of glyphosate and paraquat were assessed over two incubation terms. In this study the negative impact of the glyphosate and paraquat on the bacterial population was observed. The greatest bacterial population developed in media containing concentrations of glyphosate and paraquat was observed with strains Pseudomonas graminis, while Bacillus megaterium showed the lowest biomass production in response to all concentrations of glyphosate and paraquat. Based on the results obtained, Pseudomonas graminis was determined to be resistant to the herbicides examined and may be useful for future bioremediation studies of these compounds in soil. The positive or negative effect of herbicide on the bacteria depends on the different factors like herbicide dosage, bacteria strain, incubation time and chemical conditions of the culture medium. An increase in the bacterial population in the high concentration of glyphosate and paraquat (>100 mg/kg) reveals that these bacteria are resistant to high doses of herbicides and this result can be helpful in polluted soil adaptation and remediation.

Subject: Comparative Analysis of Artificial Neural Network and Long Short-term Memory Techniques for Predicting Air Quality in Smart Cities: Ahmadabad City
Keywords: Air pollution, Air quality prediction, Machine learning, Artificial neural network, Long short-term memory, Ahmedabad, Gujarat, India
Abstract: Over the last few decades, air quality has turned into a critical environmental issue which has made more prominent effect on human health. Because air quality greatly affects the everyday existence of human, it is essential to examine the changes in air quality and predict them precisely. Our investigation focused on gauging and foreseeing the air quality of 145 crossways/intersections for smart urban communities, like Ahmedabad, Gujarat in India independently because air quality varies from intersection to intersection as it depends on several parameters, like traffic, industrial area, time of the day, etc. The significant issue with this investigation is the accessibility of the dataset for every crossway of the city. To address the issue we have created the estimation information for the air quality index (AQI) for Ahmedabad city from a similar approach as the dataset produced for Aarhus city, Denmark. The aftereffect of this examination is promising to foresee the air quality index for the intersections, utilizing artificial neural network (ANN) and long short-term memory (LSTM). At last, we examine and compare the correctness of different configurations using root mean square error in the prediction of the actual vs predicted AQI using the proposed configuration. In this paper air quality index for Ahmedabad city is generated from the same methodology as the data of Aarhus city, Denmark generated for the period of 1/8/2018 to 1/10/2018. The previous studies were based on predicting an AQI for the whole city. The novel part of this study is to develop a dataset for the Ahmedabad city, Gujarat, India and junction wise prediction of the AQI. Moreover, the paper has proposed the client-server model to get the prediction of AQI for different 145 crossways in the city. Paper derives the conclusion that for the given dataset, the LSTM predicts AQI more accurately than the ANN. This paper is a critical inspiration for inquiring into urban air quality as well as to help the administration to design gainful strategies

Subject: A Critical Analysis of Covid-19 with Special Emphasis on Air Quality and its Consequences during Lockdown
Keywords: SARS-CoV-2, Medicinal, Spread, Lockdown, Air pollution, Environmental
Abstract: SARS-CoV-2 (Covid-19) has taken over the world. The deadly virus causes serious respiratory infections in humans. A number of research are ongoing to contain the spread of the virus. The aim of this review is to assess the impact of air pollution and environmental factors which may influence the transmission of the disease. The utilization of indigenous natural sources as remedial measures has also been explored. The studies cited in the review have been sourced from journals, books and digital media reports. The research papers indexed in databases such as PUBMED, SCOPUS and MEDLINE, etc., have been included. Evidence has suggested that the spike in air pollution may exacerbate the number of infections and the improved air quality during the lockdown period may influence the faster recovery rate. Environmental factors, like temperature, humidity and air pollution have been explored as contributing factors for the facilitated spread of the infection, or atleast in making people more vulnerable to it which makes it an issue of considerable attention in developing countries, like India, due to the high air pollution levels in megacities.

Abstract: Environmental noise is an important public health issue, featuring among the top environmental risks to health. Central Pollution Control Board in association with State Pollution Control Boards established a national ambient noise monitoring network covering metropolitan cities in the country. Under this monitoring programme, the ambient noise level of Chennai city is being monitored on real-time basis at ten stations since 2015. The noise level recorded in these ten stations during 2020 was analysed on a daily, monthly and annual basis. The daily data reveals that daytime Leq varies from 30.38-92.50 dB(A), L10 varies from 63.61-87.34 dB(A), and L90 varies from 44.38-64.82 dB(A). The nighttime Leq varies from 30.23-90.47 dB(A), L10 varies from 57.90-88.16 dB(A) and L90 varies from 40.82-65.62 dB(A). The monthly average data reveals that two stations exceeded standards in all the months. The annual average data reveals that seven stations exceeded standards. The main source of noise is the road, rail and air traffic, construction, commercial, industrial, social and entertainment activities. Ambient noise can be controlled by various mitigation strategies including traffic management, control of vehicle speed and maintenance of roads, mass awareness, removal of encroachments and providing noise barriers, like tree plantation, zoning of areas to maintain separation from excessive noise zone, ban of the bursting of firecrackers, ban of air horns, loudspeakers, limiting the use of construction equipment at night, engaging quieter vehicles for waste collection and other public services, limiting the use of loud machinery and equipment, subsidize acoustical retrofits (for example double pane windows, mechanical ventilation) for existing residential buildings near traffic noise sources, proper land use planning and comply the noise standards.

Subject: Monitoring of Trace Elements in Snow of the Northern City Agglomeration
Keywords: Trace elements, Snow, Pollution, Total reflection x-ray fluorescence spectrometry
Abstract: The study of snow for the content of various contaminants is one of the methods for monitoring the state of the atmosphere. In urban agglomerations, the study of the content of trace elements is relevant. The purpose of this study is to analyze the pollution and distribution of trace elements in a large city in Northern Europe – Arkhangelsk. The snow samples were collected in March 2015, 2019 and 2020. The snow samples were collected at 14 crossroads with maximum transport load. The concentration of trace elements was assessed in melt snow water using total external reflection x-ray fluorescence analysis. The obtained values of the concentrations of trace elements were evaluated in comparison with the standard values established as the maximum permissible in the Russian Federation and the EU and the calculation and comparison of the total pollution indices and pollution indices according to Nemerow were carried out. The results indicate that in 2015, an excess of the MPC level was recorded for such elements as iron (exceeding from 1.9-92.0 MPC levels), zinc (exceeding from 1.6-36.0 MPC levels) and manganese (exceeding from 1.1-1.2 MPC levels). The situation improved in 2019 and 2020, but the zinc content was still well above the maximum permissible content. We also calculated the total pollution indices. We found that in 2015 all the crossroads of the city of Arkhangelsk belong to the heavily polluted V class in terms of trace elements content. In 2020, these indices have dropped significantly. Statistically comparing the data obtained, it was found that the studied trace metal has a single source.

Keywords: Advanced oxidation process, Photocatalysis, Metal isonicotinate, Dye degradation, Acid Orange 7, Xylenol Orange
Abstract: Advanced oxidation processes involving the use of H2O2 as the green oxidant in presence of UV light and a catalyst are very effective in the oxidative degradation of water pollutants. Herein a few such processes involving metal (II) isonicotinate tetrahydrates, M(INA)2(H2O)4 (M=Fe, Co, Ni and Cu; INA=isonicotinate anion), as photocatalysts for oxidative degradation of Acid Orange 7 (AO7) and Xylenol Orange (XO) dyes are described. Optimization of parameters, such as initial dye concentration, catalyst dosage, pH and oxidant (H2O2) concentration influencing dye degradation efficiency has been carried out. The metal-organic catalysts being easily isolable and cost-effective complexes showing high degrees of activity in the degradation of the selected dyes, the presently developed method may be viewed as being highly promising. In terms of catalytic efficiency, while Fe(INA)2(H2O)4 is the most effective catalyst for the degradation of XO, Cu(INA)2(H2O)4 is found to be most effective in catalyzing the degradation of AO7.

Subject: Toxicity Assessment of Wastewater from Sewer System of Aurangabad City and Waluj Mahanagar Area, Maharashtra, India
Keywords: Wastewater, Heavy metal ions, Bioassay, Mortality, Toxicity, Guppy fish
Abstract: The wastewater generated from Aurangabad city area (S1) and Waluj Mahanagar, Maharastra, India suburban residential area near to industrial area (S2) is flowing through sewer systems and meets the Kham river at different places and finally meets to Jaikwadi reservoir. The treated industrial effluent from CETP containing toxic chemicals and heavy metals are discharged in Kham river somewhere near Pandharpur and Patoda villages. The sewage mixed with treated industrial wastewater may impart toxicity which was studied in test organism Guppy fish. The contaminated water of Kham river is being used for domestic and irrigation purposes in the downstream areas. The present investigation deals with the testing of physico-chemical parameters and heavy metals contents of the wastewater flowing in Kham river near Pandharpur and Patoda villages. The physico-chemical parameters, such as temperature, pH, TDS, DO, COD, BOD, SO4, PO4 and NO3; ions, namely Ca, Mg, Na and heavy metals, namely Cr, Cu, Ni, Zn, Cd and Pb were determined in year 2017. As some heavy metal ions, such as Cu, Ni, Zn and Cd contents were determined significantly in wastewater. Therefore, the toxicity assessment of wastewater was carried out in Guppy fish (Poecilia reticulata) in terms of its LC10 and LC50 through bioassay test in laboratory. The results of toxicity study of wastewater near Waluj area show the mortality in Guppy fish confirming its toxic nature. The increasing concentration of wastewater during bioassay shows the increase in mortality percentage. The quality parameters of wastewater samples from S1 and S2 sites were found, COD (131, 910 mg/L), BOD (146, 279 mg/L), SO4 (12.2, 56.3 mg/L), Ca (8.01, 4.01 mg/L) and Zn (2.19, 2.39 mg/L) respectively. The COD, BOD and Zn were recorded higher in quantities than the prescribed limits of Central Pollution Control Board, India. The LC10 and LC50 were determined to wastewater samples at 24, 48, 72 and 96 hr exposure period for samples collected from sampling sites S1 and S2. The initial percent mortalities in test organism Guppy fish were recorded as LC10=11.4853 and LC50=18.6208 for 24 hr to the wastewater collected from Waluj Mahanagar area (S2), whereas LC10=3.3551 and LC50=1.1310 for 48 hr were recorded in wastewater collected from Aurangabad area (S1) with the above results noted that initial mortality of 24 hr recorded in S2 sampling site whereas, 48 hr exposure period required in site S1. The toxic nature of wastewater indicates that there might be presence of poisonous heavy metal contents significantly which might be responsible for imparting mortality in test organism after exposure.

Subject: Theocentric Environmentalism and Man’s Role in the Preservation of Ecology – A Study
Keywords: Environment, depletion of resources, Human attitude, Society, ecological destruction, Theocentrism
Abstract: This paper is a reflection on man’s role in the utilization and depletion of God-given bountiful resources on this earth. It expands on the important aspects of theocentrism and its relevance especially in the current situation when we are faced with alarming statistics of terrible natural disasters, most of them caused by man’s indifference and carelessness. Theocentrism challenges the use of the earth’s resources and is very staunch in its approach against the unrestrained materialism and consumerism of today’s society. It challenges mankind to move beyond being selfish by seeking satisfaction from nature and perceiving nature as God designed it. It demands that it is morally right to consume in moderation and recycle or reuse resources to the utmost. This article also chronicles the history of our co-existence with nature wherein we see that it has been influenced by several factors possessing sociological and cultural colouring. There is a growing interest in studying these contexts to understand the implication of such influences on human attitude and behaviour towards nature. A lot has been done to mitigate the mistakes of the past but a lot more has to be done and at a faster pace. The authors have surveyed how people of different age groups perceive this mammoth problem of ecological destruction and devastation taking place around them.

Subject: Degradation and DT-50 of Acenaphthylene in River Sediment under Ambient Conditions and Effect of Nutrients: An HPLC and GLC Analysis
Keywords: DT-50, Acenaphthylene, Degradation, River sediment, NPK nutrients
Abstract: The degradation of acenaphthylene in river sediment was investigated in a 60 days experiment under two different chemical environments. GLC and HPLC analyses of soxhlet extracts in DCM and methanol solvent, respectively were done to find out the concentration of remaining hydrocarbon. By applying the method of integration on the results on concentration as per HPLC analysis, the rate of the chemical process was found to follow first-order kinetics. Disappearance time for 50% in days, that is DT-50 of the PAH was determined by using half-life equation of first-order reaction. It has been found that the DT-50 value under ambient conditions was found to be 41 days. Gas liquid chromatography was done for 53 min of two samples. The GLC report of first 10 min analysis exhibit that the total number of n-hexane soluble compounds in the acenaphthylene applied to soil decreases from 30 to 23 under the influence of NPK nutrients. These 23 peaks cover a total area of 96.765% in the chromatogram against 98.161% by the 30 peaks of the sample without NPK nutrients. This indicates that the presence of NPK nutrients accelerates the removal of the hydrocarbon and its derivatives from the soil.

Keywords: Periphyton, Autotrophs, Heterotrophs, Reducers, Biotic periphyton index, Saprobic index, Diatoms, Mineraliza-tion of water
Abstract: Due to the increase in anthropogenic factors, such as the expansion of industrial production, urbanization, the development of virgin lands, the construction of new roads, the use of various methods of irrigation, etc., there is an inevitable deterioration in the quality of water, both for drinking and recreational purposes. At the same time, there is a need for wider use of tools for assessing various pollution of water sources. The article provides information on the ecological state of water bodies in terms of fouling or periphyton. Periphyton (fouling) – (from the Greek perijnw- to grow, overgrow) A.L. Benning, 1924)), communities of organisms living on a variety of underwater (living or dead) substrates, raised above the bottom, regardless of their origin (hydraulic structures, walls of water pipes, on concrete slopes and snags, on aquatic plants and animals [1]. The composition of fouling includes representatives of three main functional groups: autotrophic organisms – producers (algae); heterotrophic organisms – consumers (protozoa, rotifers, worms, molluscs and others) and decomposer organisms (zoogloeal, filamentous, rod-shaped, coccoid and other forms of bacteria and fungi). Periphyton, due to its confinement to the substrate, plays a primary role in assessing the quality of water and allows one to judge its average pollution for a certain period of time prior to the study. In other words, analysis of periphyton can indicate a prior deterioration in water quality that has not been detected in one-time chemical samples. Periphyton is indispensable in studies related to the assessment of the ecological state of water systems.

Subject: Wetlands in India: A Review of Ecological Implications, Distribution, Vulnerabilities and Conservation Strategies
Keywords: Wetlands, Ecological services, Carbon sink, Anthropogenic activities, Ecological implications, Conservation strategies
Abstract: Wetlands, as the world’s most productive natural ecosystems, render enumerable ecological services, chiefly purification of water, flood control, carbon sink and stability of shoreline at a local and global scale. Globally, the wetlands are under tremendous pressure due to negative socio-economic and anthropogenic activities. In Indian subcontinent too, the issue of wetland degradation has cropped as a serious environmental concern. Aquatic habitats, namely tanks, ponds and lakes are under tremendous pressure due to unsustainable practices leading towards their degradation. Besides, conservation values and socio-economic significance of the wetlands have been deeply hampered due to the unavailability of authentic and updated information related to their development of policy, distribution on the Indian subcontinent, legal framework and government policies, etc. In the aforesaid backdrop, the present manuscript critically reviews the ecological implications of wetlands, their distribution, vulnerabilities and conservation strategies concerning the Indian subcontinent.

Subject: Treatment of Brackish Water Using Acrylic Solar Still with Concentrating Dish
Keywords: Solar still, Fins, Brackish water, Concentrating dish
Abstract: Water is essential for each and every living organisms residing in the earth. Nowaday’s earth is facing a severe water scarcity. According to the research which was done in 2019 it has been found that world will suffer severe water scarcity by the year of 2021. It is found that about 97% of water in the earth is saline water. The major cause for the water scarcity is the rise in population. It is a basic need to convert the saline or brackish water into the potable drinking water. The acrylic still enclosed with concentrating dish is a simple device which is used for converting brackish water into the potable drinking water. This paper presents a study about the acrylic solar still enclosed with concentrating dish. It gives the good productivity value and the water scarcity also be reduced by this method. This can be adopted in future for the purpose of converting brackish water into usable water and this process has the good efficiency value.
