Subject: Bioaccumulation of Heavy Metals in water, sediment and some selected Fishes from different aquaculture ponds of Badarpur, Karimganj district, Assam
Keywords: Heavy metals, fish species, accumulation
Abstract: In the present study the selected heavy metals, such as zinc (Zn), cadmium (Cd), chromium (Cr), lead (Pb), copper (Cu) and nickel (Ni) were determined in water, sediment and gill, liver, muscle of fish H. fossilis, L. rohita and O. niloticus from different aquaculture ponds of Badarpur, Karimganj district, Assam. The concentration of heavy metals varied significantly among fish species and their organs. Among the three organs muscles contained the lowest concentrations of all metals. In most studied fishes, the liver was the target organ for Cu, Zn and Fe accumulation. Pb and Cd, however, exhibited their highest concentrations in the gills. The result of the study revealed that the concentration of heavy metals in water, sediment and in different species were within the recommended limit set-up by different organizations and are considered to be safe for human consumption.

Subject: Quantification of CO2 sequestration by Campus Trees
Keywords: CO2 sequestration, Global warming, wood density
Abstract: Enhancing carbon sequestration in biomass is presently considered one of the major strategies for reducing atmospheric CO2 concentration. The present study focused on the identification of tree species in the Christian college campus, Thiruvananthapuram, Kerala, India which would efficiently respond to global warming due to the enhanced CO2 sequestration. The primary data were collected by non-destructive methods from a total of 253 individual trees. Tree height and girth at breast height were measured using a clinometer and measuring tape, respectively. Wood density of different tree species was obtained from an authentic database and parameters, namely above ground biomass (AGB), biomass ground biomass (BGB), total biomass, carbon store and the average amount of carbon dioxide sequestered by each tree were calculated. The highest total biomass was recorded by Tamarindus indica followed by Caesalpinia pulcherrima and Anacardium occidentale. The highest biomass in Caesalpinia pulcherrima can be attributed to the increased wood density in the species. Tamarindus indica exhibited the highest CO2 sequestration followed by Artocarpus heterophyllus, Caesalpinia pulcherrima, Anacardium occidentale, Delonix regia, Tectona grandis and Syzygium cumini. The amount of CO2 sequestered by Tamarindus indica was 70372.73 kg, followed by Artocarpus heterophyllus (25567.29 kg). Of the 30 families present on the campus, CO2 sequestration was highest in Fabaceae followed by moraceae. The major share of CO2 sequestration in the campus was provided by fabaceae, moraceae, myrtaceae and anacardiaceae. Present analysis revealed a perfect positive correlation between total plant biomass and CO2 sequestered with a correlation coefficient of 0.9721.

Subject: Recent Developments of Effective Sorbents Materials for Oil Spill Cleanup: A Review
Keywords: Oil spill, Sorbents, Carbon nanotube, Sorption capacity
Abstract: Oil spill in the offshore sea has been proved to be catastrophic to the marine ecology. Various cleanup methods have been proposed and tested using different methods and materials. This paper intends to discuss the recent developments related to sorbents, which play a critical role in the remediation of the oil spill. The synthesis of these materials is highlighted and the potential absorbing properties are discussed here. Some porous sorbent materials have been found with excellent absorption capacity to remove the oil from water. This study could guide further development in sorption efficiency research and applying those materials for oil spill cleanup. The modified carbon nanotube, graphene, magnetic nanoparticles and melamine sponge have carried good sorption capacity and the modification methods are capable of enhancing the hydrophobicity of these sorbents. So, an attempt was made to understand the potential oil-absorbing sorbents material and their efficiency to combat the oil spill scenarios. The cost-effective sorbent materials with eco-friendly and good recycling options would be more acceptable for future study.

Subject: Phytomediated Adsorption of Acid Blue 113 using Ananas comosus Crown, Artocarpus heteropyllus Leaves and Spent Tea Leaves
Keywords: Jackfruit, Ananas comosus, acid blue 113, phytoremediation
Abstract: Dyes and heavy metals are major toxicants found in industrial wastewater that hampers the free release of this water into water bodies. Conventional methods for removal of such pollutants from wastewater are costly and involve harsh conditions which, therefore, urges cheap methods to treat such effluent. Phytoremediation is a ‘green’ alternative for cleaning up the environment through the use of plants and plant based waste instead of mechanical removal and treatment. The objective of the present work involves the study of the removal of dye by jackfruit leaves, pineapple crown leaves and spent tea; these materials are low-cost, abundantly available, highly efficient and eco-friendly. The plant material used as adsorbent was characterized for its physico-chemical properties and surface morphology. Of the substrates used for the removal process, Ananas comosus crown leaves and Artocarpus heteropyllus leaves were found to be efficient by showing removal of 90% of the azo dye acid blue 113 compared to that of spent tea leaves. A combination of all the three substrates yielded a better removal efficiency of 99% thereby suggesting the potential of these substrates in the treatment of pollutants from the industries.

Abstract: Air pollution, a silent killer ravaging across big metropolitans can easily affect the susceptible population of certain ages very rapidly than the rest because of the level of exposure to various categories of pollutants. Of this section, the traffic police occupy the most vulnerable sect to be continuously exposed to vulnerable concentrations of air pollutants; majority of whom are above permissible limits. The consequences of heavy exposure can be seen in various anatomical systems of the body of the person. This rostrum is aimed at the analysis of the upshot of different pollutants on the health of individuals presented in line of duty in traffic. The study was concluded with the utilization of medical tests and questionnaires. After analysis of the report, it was found that both the populations are moderately to severely affected by air pollution. Small sample size has hindered procuring any further conclusions on the health status of older generation population (40-60 years old age group).

Keywords: Municipal solid waste, Landfill site selection, Gegographic information system, Multi-criteria decision making, Analytical hierarchy process, Urban local bodies
Abstract: Disposal at landfills is still one of the most preferred methods for municipal solid waste in India, though it should be the least preferred option. Most of the time government regulations and public opposition makes it extremely difficult for city planner to find a new landfill site. The combination of geographic information systems (GIS) and multi-criteria decision analysis (MCDA) can be applied successfully in such situations. The complex procedure considers various technical, environmental, economic, political and social factors. This paper uses a methodology and application of GIS for the sanitary landfill site selection for Patna, capital city of Bihar, India. Analytical hierarchy process (AHP) has been used to give weights to factors based on expert opinion and extensive study. The results indicate that there are three locations where adequate land seems available and these sites are under ‘most suitable’ category for sanitary landfilling.

Abstract: A detailed study was carried out to evaluate the geochemical processes regulating groundwater quality and to assess the suitability of waters for agriculture in Ilkalhalla sub-basin of Bagalkote and Koppal districts of Karnataka, India. The area is composed of sandstone, pink and grey granite, granodiorite, metasediments and metavolcanics. The above studies were carried out by collecting 77 representative water samples each during pre-monsoon and post-monsoon seasons. Collected water samples were subjected to physical and chemical analysis following standard operating procedures. Based on the results of analysis, irrigational parameters, such as SAR, Na%, RSC, PI and KI were calculated. Based on the TH values almost all the samples are falling in category of hard to very hard (>150 mg/L) during both seasons. Based on RSC values 7 and 20 number of water samples during PRM and POM, respectively are found to be unsuitable for use in groundwater. Based on USSL diagram, most of the water samples are falling into class of high salinity hazard type during both seasons which indicates that high salinity and low sodium waters are moderately suitable for irrigation purposes.

Abstract: SARS COVID-19 pandemic has threatened the world at various levels resulting in human loss, economic loss and environmental loss. In order to prevent the further transmission of COVID-19, a number of protective measures have been recommended and adopted by people, namely use of sanitizers, goggles, aprons, face covering, gloves and personal protective equipment (PPE) kits. Use of PPE kits has been very effective for health workers, such as doctors, nurses and policemen, however, the associated challenges including aftereffects of using PPE kits cannot be ignored completely. Same situation is being faced globally as people are using a giant volume of PPE in order to protect themselves from COVID-19 pandemic and its excessive use is generating huge quantity of PPE waste. This waste is causing huge environmental degradation, namely contamination of water, air and soil quality. In this paper an attempt has been made to describe the impact of PPE kits on human beings and global environment due to improper disposal methods. It also highlights the skin and respiratory problems confronted by healthcare workers caused by the use of PPE kits for extended hours indicating its long term impact on healthy living. A sustainable way of disposal and management of PPE waste has also been described.

Keywords: Mathura city, Noise pollution, Sound level meter, Federal Highway Administration, Health hazard, Road traffic noise pollution
Abstract: This research paper studied the background noise level of Mathura region. Exposure to a high level of sound pollution may lead to stress on the auditory and nervous systems. Traffic on some state highways at many locations, presence of heavy electricity generators and development of commercial zones are the main source of sound pollution in Mathura city. The study was conducted in March 2021. The traffic noise along highway corridors on national highways (NH–19) passing near Mathura city was administered at 4 different zones (silence zone, residential zone, commercial zone and industrial zone) with 5 specific locations with background level meter (Bruel and Kjaer, SL-4030) to access the day and night sound levels in Mathura city. The traffic noise prediction was completed with the assistance of the Fed us points within Mathura city at different locations near the highway during day hours were 52.2 dB and 92.4 dB and in night hours were 36.3 dB and 85.6 dB. The extent of noise was found to tend to the prescribed noise standard level of CPCB. Thus, it shows that Federal Highway Administration (FHWA) model is often used for the predictions of traffic noise in India under its limitations of accuracy. Day by day the noise pollution levels cross the given standard limits everywhere on the earth, so this often have a greater health risk to the exposed population, therefore, control measures should be initiated and supported on priority basis. Additionally, this research paper reviews the study on noise monitoring and noise mapping directed in several countries by many scholars. It reveals that only 10% of data are focused on the residential, commercial and industrial areas and rest 90% of data used in noise monitoring studies are focused on traffic noise pollution.

Abstract: Pure PVAc and PVAc-MgO (polyvinyl acetate-magnesium oxide) nanocomposite membranes were fabricated by solution casting and solvent evaporation methods. Nanocomposite membranes were characterized by the x-ray diffractometer (XRD), differential scanning calorimetry (DSC) and thermogravimetric (TGA) analyser to study the effect of MgO nanoparticles loading on structure, glass transition temperature (Tg) and thermal stability of membrane. The performance of prepared membranes was evaluated in terms of permeability and selectivity of gases to study the effect of MgO loading on gas transport properties. CO2 + H2 mixed gas permeation test was carried out at fixed 24ºC temperature and 3 bar pressure. Obtained result shows that addition of MgO nanoparticles enhances the amorphous regions, thermal stability and glass transition temperature of membrane. Mixed gas permeation test shows that addition of MgO nanoparticles in the PVAc increases permeability of both CO2 and H2 and decreases H2/CO2 selectivity. The highest permeability of CO2 and H2 gas for PVAc-20% MgO nanocomposite membrane was found to be 9.889 and 12.120 barrer.

Subject: Development of Handmade Geomesh from Paddy Straw for Erosion Control and Air Pollution Abatement
Keywords: Paddy straw geomesh, Rainfall intensity, Slope erosion control, Tensile strength
Abstract: Paddy straw, abundantly produced in northern India is stacked in the field after its harvest. Financial liability to clear straw from their field for next crop forces farmers to take desperate decision to resort to open field burning causing severe air pollution. Global climate change also has catastrophic impact on the built environment in the form of incessant rains to cause erosion of slopes of newly built embankments. Control of erosion of such slopes would increase security and safety of the infrastructure. In the present work, paddy straw is used as an alternative to high ended materials, like jute and coir, to manufacture rolled erosion control products (RECP). The claim of paddy straw is justified since it has same chemical composition as that of jute and coir. Thus using IS15868 part 1 to 6, a mesh type rolled erosion control product (RECP), made from stems of paddy straw, using handmade technique and labelled as 6PSG-12 (12 referring to aperture size in mm) is proposed [1]. Paddy straw geomesh (6PSG-12) was tested and found to possess important index properties, like tensile strength, drapability and durability. Similarly bench scale testing has confirmed effectiveness of 6PSG-12 in controlling slope erosion in the field.

Subject: Implementation of Qual 2K Model for Water Quality Simulation in a Selected Stretch of Gomti River
Keywords: Gomti river, QUAL 2K, River pollution, Drains, Point sources, Water quality prediction, Simulation
Abstract: Gomti river, the main tributary of Ganga river receives huge amount of untreated effluents through various point and non-point sources along its stretch. The application of QUAL 2K model simulates the water quality of some major drains applied as point sources for a selected stretch of Gomti river. The analysis involved the calibration of winter season (Dec-Jan 2018) data and validation of summer season (April-May 2019) data for flow discharge (Q), pH, dissolved oxygen (DO), biochemical oxygen demand (BOD5) and total suspended solids (TSS). The performance of the model was measured by statistical method of correlation coefficient (R2)=±0.30 to ±0.57 (moderate to high degree) between two variables, observed and simulated data. The results showed that there was continuous deterioration of DO (6.4±0.7), while increase in BOD5 (2.6±108) signifies that the water is neither suitable for drinking nor for aquatic life and also unfit for irrigation. The results of simulation were validated and showed close relationship with observed values. Assessment of the present status of the Gomti river indicates that stringent measures (wastewater treatment plants) and soft measures have to be taken to save sanctity of the river.

Subject: Large variation in concentrations of ultrafine (PM1) and coarse (PM10) mode particulate matter during lockdown and unlock phases of Covid-19
Keywords: COVID-19, Coarse particulate matter, gaseous pollutants, Lockdown phases, Ultrafine particulate matter
Abstract: Due to the strict enforcement of lockdown, the air quality index improved drastically in the cities across the globe within a few days of lockdown globally. The present study was conducted in Jaipur city to evaluate the effect of lockdown phases on the concentrations of PM10, PM1, NO2, SO2, CO and O3. Among the selected pollutants PM1 (-61.15%) and PM10 (-40.50%) witnessed the maximum reduction in the lockdown phase 1. Among others, gaseous pollutants also showed a declining trend, as NO2 (-69.61%) witnessed maximum reduction followed by CO (-25%) and S O2 (-13.74%). In contrast to this, the O3 (+24.26%) showed the opposite trend. The decreasing trend of pollutant concentrations continued upto the 2nd phase of lockdown, after which conditional relaxations in restrictions led to an increase in pollutants. In comparison to last year (that is 2019) during the same period, the concentration of atmospheric pollutants in 2020 was found to be very low. Ultrafine particulate matter showed a decreasing trend throughout the study whereas coarse mode particles shows a decreasing trend till the 3rd phase of lockdown and increased later on. Whereas, most of the gaseous pollutants show a decreasing trend in almost all phases except O3 showing a reverse trend.
