Keywords: Polyethylene, Pollution, Degradation, Energy dispersive X-ray, Fourier transform infra-red spectroscopy
Abstract: Polyethylene has emerged as the most used plastic material around the globe. Main benefit of polyethylene being used widely is its durability and resistance to numerous chemicals. These properties of polyethylene have made it resistant to degradation leading to its accumulation in the environment, ultimately results in major environmental pollution. In order to deal with plastic pollution, researchers are engaged in finding eco-friendly ways to degrade plastic, like polyethylene. Commonly there are three types of methods for degrading polyethylene, like biological, chemical and physical methods. So, in the study presented here the chemical way of dealing with the low density polyethylene waste has been done. Basically three chemical surfactants sodium dodecyl sulphate (SDS), cetyl trimethyl ammonium bromide (CTAB) and Tween 80 in different concentrations were used for the study. The results of energy dispersive X-ray, X- ray diffraction and Fourier transform infra-red spectroscopy revealed that SDS was found to be more effective in oxidizing polyethylene.

Subject: Impact of Air Quality Variations on COVID-19 Determinants: A Study of Four Selected Cities of India
Keywords: SARS-CoV2, COVID-19, Air quality index, Air pollution, Fine particulate matter
Abstract: Governments across the world are making considerable efforts in confronting COVID-19, from nationwide lockdowns to hygiene measures and maintaining social distancing. But at the same time, role of aerosols or/and the high concentrations of fine particulate matter or/and AQI levels in infection transmission and increasing the prevalence, morbidity and mortality of pandemic has been largely unexplored specifically in India where pollution attains peak in October and November every year. In the present study, we collected data regarding air quality index and COVID-19 determinants of four Indian cities : Bangalore, Delhi, Mumbai and Shillong from 1 October 2020 to 16 November 2020. We performed an analysis of variance on the regression model to estimate and quantify the strength of relationship between COVID-19 determinants and air pollution index (AQI). Results show that AQI has a significant impact on both response variables, that is COVID-19 cases as well as mortality (p<0.05 at 95% confidence level) in Delhi, Mumbai and Bangalore (p<0.05) but in Shillong no impact of AQI on COVID-19 cases and AQI (p=0.343), as well as deaths (p=0.664), was observed. We conclude that it is both conceivable and reasonable to suspect the role of increased AQI levels in aggravating COVID-19 morbidity and mortality. Thus, we recommend that critical meteorological conditions, like haze/smog caused by factors, like stubble burning or firing crackers should be predicted and monitored more systematically as they may lead to deterioration of respiratory problems. As the whole world is striving to fight against the deadly pandemic, it is extremely imperative to focus not only on human health as a part of response but also on global planetary health. Short term measures that can minimize supplementary risks, like adverse weather situations including pollution, poor air quality should be considered more meticulously and judiciously so that new flares of COVID-19 morbidity and mortality can be restricted.

Subject: Human Health Risk Assessment due to Arsenic in Drinking Water: A Case of Bhojpur, Bihar
Keywords: Arsenic, groundwater, Sinha block, Monte Carlo simulation, Exposure assessment
Abstract: This study discusses the risk posed to the residents of Sinha block, Bhojpur district, Bihar due to consuming reportedly high levels of arsenic-contaminated groundwater. Samples have shown an elevated level of arsenic concentration in the range of 43.32-395.20 µg/L with an average of 186.26 and a standard deviation of 110.64. The average daily dose (ADD) was calculated using the integrated risk assessment system (IRIS) developed by USEPA, for three age groups, namely children (0-6 years), teens (6-16 years) and adults (>16 years). Results showed 100 times greater ADD than the safe limit of 0.0003 mg/kg/day. The mean hazard quotient had shown a very high value of 36.1 which can be concluded as a severe non-carcinogenic risk threat to the study area. Carcinogenic risk (CR) value >10-6 indicates potential risk and the safe limit of carcinogenic risk is <10-4 when results were compared to these values, we found a very high risk of 10-2. Children and the adults in the study are found to be more susceptible to risk. For assessing uncertainty and sensitivity of inputs variables Monte Carlo simulation was used.

Subject: Imidacloprid Pesticide residues: The estimation of Lipid peroxidation and Osmotic Fragility effects
Keywords: Imidacloprid, Residues, In-vitro, Lipid peroxidation, Hemolytic activity
Abstract: The objectives of this study are to quantify the imidacloprid pesticide residues in cucumber samples; to study the in-vitro effects of this pesticide on lipid peroxidation and hemolytic activity and finally, based on the mathematical models we estimate the values equivalent to the concentrations of pesticide residues detected in the vegetable samples. For the extraction of pesticide residues from vegetable samples we used the FaPEx kits. Agilent Technologies 1260 infinity high performance liquid chromatography having UV/visible detector was used for the identification and quantification of pesticides residues. The results of this study proved the presence of pesticide residues in cucumber tested with higher values compared with their corresponding MRLs. The in-vitro study of the effects of the imidacloprid pesticide on lipid peroxidation and hemolytic activity demonstrate significant effects of the different concentrations on both activities. The estimation by mathematical models of malondialdehyde quantity and hemolytic activity equivalent to the concentrations of the pesticide residues detected in vegetable samples proved the non-toxicity effects of these residues.

Subject: A Survey on Statistical Methods used in Air Quality Prediction
Keywords: Autoregressive integrated moving average, forecasting, kriging, multivariate linear regression analysis, air pollution
Abstract: Air quality is a matter of prime concern nowadays. When the air gets contaminated or has exceeded the permissible concentration values of some constituents, it is termed air pollution. It may harm the ecological system as well as the natural conditions for the existence of humans. This situation has motivated scholars to conduct significant research work in this area. In such research, the prediction of air quality has been the focus. Prediction of air pollution provides a basis for taking effective precautionary pollution control measures. This article deals with the statistical techniques for the analysis and prediction of air pollution. For this, databases were searched for the relevant literature published during the decade. Studies were reviewed and the methodologies adopted were analysed by comparing their advantages and disadvantages. Non-linear techniques are better than linear techniques to predict air pollution. Among the technologies developed so far, multivariate linear regression analysis is the most common and widely used technique. Artificial neural networks (ANN), support vector machines (SVM) and hybrid models have shown the calibre for better prediction in future. It has been found that there is further scope to improve the accuracy of prediction. Thus, this area is quite open, unsaturated and promising and therefore, it is hoped that the present review will provide helpful guidelines for the forthcoming researchers in this domain.

Keywords: Spark-ignition engine, Alternative fuels, Exhaust emissions, Catalytic converter, Air injection
Abstract: Health hazards, environmental impact and greenhouse effect caused by spark-ignition engine emissions of carbon monoxide (CO), unburnt hydrocarbons (UBHC) emissions and nitrogen oxide (NOx) are to be immediately addressed. Alcohols are important substitutes for gasoline, as their properties are comparable to gasoline fuel, especially their cetane numbers are higher than that of gasoline. If the engine is run with alcohol, carcinogenic aldehydes are also to be checked. Investigations were carried out to control pollutants from a four-stroke, variable speed, variable compression ratio, single-cylinder, spark-ignition (SI) engine, with normal butanol, blended gasoline (80% gasoline and 20% butanol by volume) provided with catalytic converter with copper as a catalyst and compared with conventional SI engine (CE) with neat gasoline operation. Exhaust emissions of CO, HC and NOx were evaluated at different values of brake mean effective pressure of the engine. A microprocessor-based analyser was used for the measurement of nitrogen oxide levels and CO/HC in the exhaust of the engine. Formaldehyde and acetaldehyde levels were measured by wet-method. The engine was provided with a catalytic converter with copper as a catalyst along with air injection. Catalytic converter with air injection significantly reduced pollutants with test fuels.

Keywords: Fishes, heavy metals, haematological changes, pollutants, physiological changes, water
Abstract: Heavy metals are metallic elements with high atomic weight and a much greater density (atleast five times) than water. The attractive name for the group of elements is ‘trace metals’. There are more than 20 heavy metals. The heavy metals, such as cadmium (Cd), chromium (Cr), copper (Cu), mercury (Hg), nickel (Ni), lead (Pb) and zinc (Zn), among which lead (Pb), cadmium (Cd), mercury (Hg) and inorganic arsenic (As) show harmful effects to human health. The fish is a bio-marker of aquatic medium. Fishes have been perceived as a good gatherer of natural and inorganic pollutants. Against this backdrop, the present study has been assessed. Heavy metals (Pb, Zn, Cu, Cd) in selected water bodies of Rajapalayam taluk and accumulation of heavy metals (Pb, Zn, Cu and Cd) in the selected freshwater fishes (Oreochromis mossambicus, Catla catla, Mystus aor, Channa striata) and their haematological changes (total RBC count, WBC count, haemoglobin content) and physiological changes (opercular movement and oxygen consumption) were studied.

Subject: Fabrication, Characterization and Evaluation of Photocatalytic Efficiency of CdS/Fe2O3/TiO2 under Solar Light Irradiation
Keywords: CdS/Fe2O3/TiO2 ternary composites, Reactive Black 5, Solar light irradiation, anatase phase, Reusability
Abstract: The ternary heterojunction composites have been prepared and evaluated from their activity in the degradation of reactive black 5 in the presence of UV-visible light. The mineralization of reactive dyes with triazine groups has been reported to be more difficult in most treatment methods. However, at higher concentrations, the dye solutions, especially chlorotriazine dye transmit only very small portion of photons to reach the photocatalyst surface. Hence, degradation of these dyes at higher concentration levels is more difficult by using single photocatalysts. However, in most cases combination of two or more photocatalyst are found to be more efficient than the individual photocatalyst for the degradation of higher concentration dyes. Hence, CdS/Fe2O3/TiO2 ternary composites (CFT) showed higher photocatalytic activity than that of CdS, TiO2, Fe2O3, CdS/TiO2 and CdS Fe2O3/TiO2. CFT ternary composites show favourable photocatalytic activity at pH 3. All the photocatalysts show anatase crystalline phase was confirmed by X-Ray diffraction analysis. The CFT ternary photocatalyst shows an absorption threshold extended into the visible region and also has smaller particle size compared to binary and bare photocatalytic systems.

Keywords: River Yamuna, Dissolved oxygen, Biochemical oxygen demand, Heavy metals, Vigna radiata, Vigna mungo, Growth parameters
Abstract: In current years, water quality of river Yamuna has degraded drastically due to rapid socio-economic development and various anthropogenic activities. As per Central Pollution Control Board (CPCB) the water quality of river Yamuna is of category E which makes it fit only for irrigation, industrial cooling and controlled waste disposal. Current study revealed the effect of Yamuna water on cultivars of two economically important crop legumes, that is Vigna radiata (PUSA1431 and PUSA9531) and Vigna mungo (KU6 and MASH114) collected from PUSA (Pulse laboratory). Water samples were collected from two locations one is entry point of Yamuna in Delhi, that is stretch of Wazirabad and one is exit point from Delhi, that is Okhla route. Different water quality parameters, such as pH, colour and odour have been recorded while collection, total dissolved solids (TDS), total suspended solids (TSS) and heavy metals have also, been determined. Dissolved oxygen (DO) and biochemical oxygen demand (BOD) of water samples have been determined by Winkler’s method and dilution method, respectively. Effect of different water samples on cultivars of Vigna radiata and Vigna mungo were determined by observing different growth parameters including percentage germination, length of roots and shoots, weight of fresh and dried seedlings at different time intervals.

Abstract: Landslides are one of the major natural hazards that accounts for hundreds of lives, damaging properties and blocking connection links every year. It is a very common phenomenon in the Himalayas. The area chosen in the present work is the Bhimtal region of Nainital district, Uttarakhand having a 22.6 km2 area. Bhimtal township located in the Kumaun Lesser Himalaya is known to be vulnerable to landslides in the past. Kumaun Lesser Himalaya is lying between Nepal and Himachal Pradesh borders. It is considered one of the most fascinating segments of the Himalayas and has unique geological settings. Bhimtal town is situated at an altitude of 1370 m above mean sea level. It is located between 29°18‘N and 29°28‘N latitudes and 79°32‘E and 79°37‘E longitudes. It is fast becoming a tourist region where lots of hotels and resorts are coming up consuming the already depleting land. The main road that passes through the study area has been affected by landslides before. The main aim of this research work is to create a landslide hazard zonation (LHZ) map based on total estimated hazard (TEHD) which is calculated for each facet based on factor ratings and to analyze the stability of roadside hill slopes using geotechnical investigation, so it can be used for effective and efficient disaster management. ArcGIS 10.3, Google Earth Pro 7.3.2, Excel software have been used for creating factor maps, exporting features and calculating total estimated hazard (TEHD), respectively. The study also includes the primary investigation of the site, collection of soil samples, testing of samples, analysis of test results and conducting slope stability analysis. The slope stability analysis is supplemented by using a numerical equations based on soil parameters. Soil samples were collected and were tested for water content, sieve analysis, hydrometer analysis, Atterberg‘s limit, specific gravity and unconfined compressive strength (UCS) by following the Indian Standard method for soil test procedures.

Subject: Biosorptive Removal of Mercury from Farmland Soil Vicinity of Industrial Area
Keywords: Mercury (II), Biomass, Adsorption, Column mode, Atomic absorption spectrophotometer, FTIR
Abstract: Effective removal of Hg (II) from contaminated soil was carried out using biosorption plant as a derived material. Consequently, a native shrub, Cicer arietinum was observed as the most acceptable biosorbent. The plant biosorbent was observed by different parameters, such as concentration, pH, dosage, temperature, equilibrium time and the appropriate adsorption models. The most favourable pH observed was 4.0 with a contact time of 50 min at room temperature (26±2°C). Data obtained from experiment was well fitted to the graph of adsorption isotherms and the uptake capacity of Hg (II) was noted as 18.91 mg/g in column mode. Concentration of Hg ion was identified using atomic absorption spectrophotometer. It shows that concentration is high near power plant industry (50 m) as 1.901 mg/kg and low away from industry (4500 m) as 0.011 mg/kg. The removal of mercury in bioadsorbent was confirmed by Fourier transform infrared spectroscopy (FTIR). Involvement of hydroxyl (-OH), fluoro (C-F) and alkenes (=CH) group was indicated by the FTIR analysis which shows chelate – metal binding. The bioadsorbent was taken for the removal of Hg (II) in real soil samples collected around power plant industry. It is also remarkable that at the high concentration of 100 mg/L, the bioadsorbent shows about 92% removal. Result found the efficiency of C. arietinum as very good biomass for the removal of Hg (II) from contaminated soil.

Abstract: Groundwater characterization and exploration require detailed information about the sub-surface condition. Such information is possible to obtain from geophysical techniques. A vertical electrical sounding (VES) is an important approach to detect the vertical variations in the geo-electrical parameters. The changes of resistivity below the measuring point are utilized in characterizing the sub-surface conditions. The present study involves the geo-electrical characterization of the selected places at 11 locations in Kasaragod and Kannur districts of Kerala state, India. This study helps to understand the status and hydrological behaviour of the area. Schlumberger method has been used for conducting the VES surveys in the study area. The study provides the information needed for groundwater management in the study area.

Subject: A State of the Art Review on Air Quality at Visakhapatnam During Lockdown
Keywords: None
Abstract: Post reporting of deadly virus infecting mankind in city of Wuhan (China) major changes in socio-economic conditions have been encountered. Being reported on 31st December 2019, later named Covid-19 disease has been declared global pandemic on March 11th, 2020 by WHO. Assuming 40-60% people of entire world might get affected due to this virus, lockdown was imposed as an immediate action. This was to curtail transmission of virus through physical contact. This lockdown has shown significant impact on air pollution on a global scale which needs to be analysed for further requirements. It is a known fact that air pollution impacts human respiratory system. Hence analysis of particulate matter and air pollutants post-lockdown and pre-lockdown during Covid pandemic may yield significant results. Even though treatment and prevention of Covid-19 is a big challenge right now, role of nanotechnology should not be ignored. Since nanotechnology is a multidisciplinary and focused field, it is capable of pivoting solutions for problems posed due to this virus and could relieve the excess strained hospitals. Since Covid-19 work on a nanoscale idea of using nanotechnology may offer significant results in the biomedical field that include both diagnostic and therapeutic approaches. In this context an attempt was made to review some of the published results related to the nature of virus and role of nano and microparticles on Covid-19 as well as to analyse particulate matter and air pollutants for a coastal, urban, industrial station in Visakhapatnam India.

Abstract: Passive downdraft evaporative cooling (PDEC) system is a traditional technique of air cooling in hot and dry climates of deserts of Iraq, Tehran, Turkey and Egypt. In present work, PDEC system is restudied for its usefulness, limitations and drawbacks and probable modifications have been suggested to suit energy requirements of built forms. In the present work, efforts have been made to study and design to modify traditional PDEC system and improve its cooling efficiency with help of design of field experimentation, experimental variables, controls and treatments. Theoretical modified PDEC models has been suggested for field experimentation based on the shower model given by B. Givoni. Geometric design of wind catcher has been altered in innovative ways to improve its wind capture efficiency. Modified PDEC shaft square in cross-section is reduced to half of its size from top to bottom to increase wind flow rate of cooled air. Nocturnal water cooling techniques are used to improve air cooling efficiency. Three different water treatments have been studied for wind-catcher conditions for field experimentation model.
