Subject: Effect of acidic Environment on Concrete
Keywords: Acid assault, Acidic environment, Reuse of copper slag
Abstract: Due to the alkaline composition of concrete, it is vulnerable to acid assault. Globally, the socio-economic costs associated with infrastructure degradation as a result of acid assault reach billions of dollars. A controlled experiment was conducted to determine the most effective acid for immersion. Batch tests were performed to determine the effect of 2% H2SO4, 2% HNO3 and 2% HCl in acid immersion. It was observed that H2SO4 immersion resulted in the greatest loss of compressive strength in concrete and that HCl immersion resulted in the least loss of compressive strength. In batch tests, sand was substituted with 20%, 40% and 60% copper slag to determine the effect of copper slag on the strength of concrete in an acidic environment. It is found that copper slag concrete mixes exhibit a much lower percentage loss of compressive strength than standard concrete mixes throughout all durations of acid exposure. It was observed that the mass of compressive strength lost by conventional concrete is almost twice that of copper slag concrete after H2SO4 acid immersion. The findings indicated that copper slag concrete is acid resistant in terms of mass loss and compressive strength loss.

Subject: Comparative Study of RUSLE and USLE Soil Erosion Models using Remote Sensing and GIS for the Ganga River Basin in Fatehpur District, Uttar Pradesh, India
Keywords: Remote sensing, Soil erosion, RUSLE/USLE, Ganga river, GIS
Abstract: Soil erosion is a major problem for agricultural land in different parts of the world which is mainly affecting the top layer of the soil. Hence, the main aim of this research was to evaluate the average annual soil loss using geospatial tools and techniques with different models for the Ganga River basin in Fatehpur region, Uttar Pradesh, India. In present research work, a comparative study of revised universal soil loss erosion (RUSLE) model and universal soil loss erosion (USLE) model has been done to estimate the annual soil erosion loss in tonne/ha/year. In this study, various datasets have been acquired from different authentic sources for the study area and a conceptual methodology has been applied to calculate the annual average soil loss factor (A). These datasets were processed in ESRI ArcGIS 10.5 and ERDAS imagine software with key informant interview (KII) to prepare the digital thematic layer of input parameters, such as rainfall erosivity factor (R), cover and management factor (C), supporting conservation practice factor (P), slope length and steepness factor (LS) and soil erodibility factor (K). Furthermore, the raster layer of annual soil loss factor (A) has been classified into four categories, such as no erosion, low erosion, moderate erosion and high erosion. As a result, polynomial relationship, using trend analysis, between these two models was analysed as y=0.0119x2+0.362x+2.97 with R2 value to be 0.998. This study would be beneficial for administration for mitigation of soil erosion in the river basin as well as socio-economic activities for the local people.

Subject: Enhancement in California Bearing Ratio values of expansive soil sub-grades using Bagasse ash and Geosynthetics
Keywords: Expansive soil, Bagasse ash, Geotextile, California bearing ratio, Multiple linear regression analysis, Artificial neural network
Abstract: The pavement structure retort depends on the sub-grade characteristics, which provide the support base. Problems allied with the construction of pavement become far more critical, particularly in regions where the sub-grade consists of expansive soils. For the design of pavements, the California bearing ratio (CBR) value is a required parameter that decides the strength of the sub-grade soil. An attempt has been made in the present study to estimate the soaked CBR of highly compressible clayey (CH) soil stabilized with bagasse ash and reinforced with geotextiles. The soil is treated with sugarcane bagasse ash (BA) in varying percentages and geotextile reinforcement in varying layers. The CBR test on the stabilized and reinforced soil specimen is conducted to assess the strength of the soil specimen. The impartial of this paper is to predict the CBR value by correlating the optimum moisture content, maximum dry density, plasticity index, percentage of BA and the number of geotextile layers. The linear relationships between the above-mentioned properties and CBR value using multiple linear regression analysis resulted in a strong correlation between the parameters.

Subject: Noise Pollution, its Causes and Health Consequences in Bangladesh
Keywords: Bangladesh, Dhaka, Noise pollution, Human health, Urban life
Abstract: Noise pollution is, in addition to water and air problems, one of the emerging hazards that affect the quality of life in Bangladesh, especially in its capital city Dhaka, badly. The level of noise pollution in most parts of the metropolitan region exceeds stipulated standard limits by upto 20 dB. Even in the morning hours, it does not fall below 55 dB in the so-called silent zones. The World Health Organization (WHO) reported a number of adverse effects of long exposure to moderate level noise or sudden exposure to excessive noise. The majority of Dhaka (the capital city of Bangladesh) residents are reportedly unaware of the negative impacts of noise pollution. Even they do not think of noise as a pollutant and treat it as a part of their daily life. However, people nowadays start realizing the adverse impact of noise pollution and the importance of noise pollution control. But, people are not properly aware of the issue. Therefore, there is still much work to be done to educate the people in this regard. The concerned authorities’ actions in this regard are not adequate enough to address this burning issue properly. Moreover, the existing environmental regulations in Bangladesh are also not satisfactory to deal with this invisible enemy. The existing paper aims to determine the causes of noise pollution and its impacts on urban life; scrutinize the prevailing related laws and policies and conclude with recommendations to stop noise pollution.

Abstract: Groundwater quality and availability are essential for human consumption, domestic and irrigation purposes. Since water quality has a significant impact on human health, it demands compulsory continuous monitoring to ensure water quality. The water quality of Theni district, Tamil Nadu was studied by a field survey for a period of three years (2018-2020). Various water quality indices were calculated and analyzed for the purpose of drinking, domestic, irrigation and corrosivity nature. The analysis of spatial distribution map of domestic water quality index and corrosivity index revealed that north-west part of the area has good water quality. Based on the analysis of spatial distribution map of irrigation water quality indices, south-west part of the study area was excellent for irrigation. The spatial distribution of all calculated water quality indices reported that south-east part of the study area needs special attention in terms of monitoring and sustainable management.

Subject: Development of a Composite Material for the Adsorption of Heavy Metals from Aqueous Solution
Keywords: Adsorption, Composite adsorbent, Heavy metals, Fly-ash
Abstract: A new composite adsorbent was developed in this study to remove the heavy metals from the aqueous solution. Flyash, activated carbon (regenerated from the water filter system installed at homes) and iron oxide were mixed in 2:1:1 and then followed several treatment processes to form composite adsorbent. Batch study was performed to investigate the effect of adsorption parameters (pH, contact period and adsorbent dose) on the removal efficiency. The adsorption process was found to be much more dependent on pH and dose of adsorbent while contact period did not play a significant role. The pH between 7 and 9 was most favourable for adsorption in this study for all the selected heavy metals. At a minimum contact period of 15 min, there was a removal efficiency of around 70-80% while the equilibrium period was in the range of 60-120 min. The adsorption capacities for the selected heavy metals were in decreasing order of Fe (12.04 mg/g) > Zn (11.425 mg/g) > Pb (11.206 mg/g) > Cu (0.69 mg/g). On the observation of the result of this study, the prepared adsorbent has the potential to remove heavy metals from aqueous solution.

Subject: Evaluation of Water Quality of Harmu River: a Tributary of Subarnarekha Basin using Multivariate Analysis
Keywords: Harmu river, Water quality, Water quality pollution level, Factor analysis, Principal component analysis
Abstract: Water quality observation data were collected from 10 representative monitoring sites located in the mainstream of the Harmu river and its tributaries between 2017 and 2021. Based on these data, the water quality and characteristics of harmu river were evaluated by conducting multivariate statistical analysis for 8 pollution indicators. Monitoring site M1 is starting point of the river harmu in city Ranchi and monitoring site M10 is located downstream of the Harmu river, exhibited high-concentration tendencies. The monitoring sites located near the city and midstream and downstream of the Harmu river exhibited high pollution levels in the investigation. To analyse the spatial and temporal variations in the water quality at 10 major monitoring sites in the harmu river, a tributary of Subarnarekha basin, principal component and factor analyses were conducted by separating the average water quality data based upon (a) monitoring site and (b) season. As a result, three factors were obtained for (a) and (b), respectively. In the Harmu river, the first factor was shown to be organic pollutants (total organic carbon and chemical oxygen demand) and as a result of cluster analysis, two statistically significant groups were classified. The results of multivariate statistical analysis indicated that the monitoring sites with high levels of pollution were mostly those sites going through the heart of the city or the sites affected by residential sewage directly, as well as the sites located midstream and downstream of the Harmu river. The water quality pollution level was calculated based on the above study results and priorities for water quality improvement items required in future watershed management were determined in order to facilitate efficient water quality management.

Abstract: The environment is never spared from the pollution which threatens its elements, in particular the soil, especially if it is in an industrial activity zone. because of its direct impact on human health and other living organisms, its preservation and protection have, therefore, become everyone’s business. In order to confirm it, this study has come to assess the concentration of certain heavy elements, such as cobalt (Co), manganese (Mn) and lead (Pb) in the surface soil of the area of Touggourt industrial activity, using the latest indicators of environmental pollution. the highest contamination factor (CF) values for cobalt, manganese and lead were 0.277, 0.008 and 0.292, respectively. While the enrichment factor (EF) values were 41.79 for cobalt and 50.49 for lead. The maximum value of the pollutant load index (PLI) was recorded as 0.133. According to these pollution indices, the results of this study have indicated that human effects or industrial wastes and traffic in particular were the sources of heavy metal contamination in the studied region.

Abstract: To determine the anthropogenic effect on the water quality and plankton biodiversity, a study was conducted at four sites along Ganges (Hooghly) river estuary and another four sites at Gangasagar, extreme southern part of Sagar island, western part of Indian Sundarban. Two different events, namely idol immersion after Durga puja and Gangasagar mela (GSM), which hugely responsible for the deterioration of the total aquatic heath, was chosen for this study. The hydrological parameters showed considerable heterogeneity for both the events – idol immersion and Gangasagar mela. Dissolved oxygen (DO), also correlated with pH, showed the maximum (5.81) and minimum (4.09) value during GSM and immersion, respectively. The turbidity value was found to be maximum at Babughat (19.5) during the immersion of idol. On average, maximum chlorophyll a concentration was recorded during post event periods, coinciding with maximum abundance and diversity of phytoplankton. The pattern of tintinnid ciliate (dominant microzooplankton) distribution exhibited relatively lower values during the events and an increasing trend towards the end of the events. Maximum (557 in/dL) and minimum numerical abundance (51 in/dL) of tintinnids were noticed during post and during the event, respectively. Our data support a positive relationship with the spatial and temporal fluctuations of phytoplankton with tintinnids.

Keywords: Landuse/land cover, Change rate calculation, Geo-spatial indices, Korba coalfield region, Chhattisgarh
Abstract: This present study has been made carried out for the analysis of landuse land cover (LULC) changes in Korba Coalfield, Chhattisgarh, from last 19 years of data (that is 2002-2021). Remote sensing and GIS datasets were adopted to analyse spatial-temporal changes. LULC classes were classified mainly into barren land, built-up area, cropland, forest area, mining area and water bodies. The maximum likelihood method of supervised classification (ArcGIS software) was adopted to classify selected images into suitable LULC classes. The changes in land cover are detected on 5–7 year time interval using satellite data of Landsat 4-5 TM, Landsat-8 OLI and TIRS with different geo-spatial indices, like normalized difference vegetation index (NDVI), normalized difference water index (NDWI) and normalized difference soil index (NDSI). The observations show that cropland and forest area indicate maximum degradation and decreased with net change by 58.57 km2 in 2002 and 82.54 km2 in 2021(-16.03 km2) and 40.69 km2 in 2002 and 32.24 km2 in 2021 (-8.45 km2) whereas built-up area and mining area have increased with net change by 29.38 km2 in 2002 and 39.64 km2 in 2021 (+10.26 km2) and 28.48 km2 in 2002 and 38.81 km2 in 2021 (+8.33 km2), respectively. Apart from this, barren land and water bodies were also increased with net change by 22.86 km2 in 2002 and 26.53 km2 in 2021 (+3.67 km2) and 6.59 km2 in 2002 and 8.81 km2 in 2021 (+2.22 km2). Net change, percentage change and rate of change in land cover of different classes were also calculated. Therefore, these used indices are very reliable for mapping as well as monitoring different land cover changes over a large extent in mining areas.

Subject: Zero Waste Package Free Shops in India: The Green Road Ahead
Keywords: zero-waste, package-free shops, Sustainable development
Abstract: Package-free stores or zero waste stores are emerging as an innovative sustainable concept these days. This paper attempts to analyze the modus operandi of package free stores in India, their main features and the challenges that they face. Data was collected from five package-free shops in India among which one store has multiple branches across the nation. As of today, these stores cover almost the entire population. The findings suggest that these stores promote sustainable consumption among the people and also meet three important sustainable development goals (SDGs). They uplift the local economy and contribute to the economic prosperity of local residents and businesses by supporting local and regional farmers. It provides toxic-free products contributing to a healthy society by renouncing plastic completely. It protects the environment thereby increasing the growth of the local economy. Since the movement towards sustainable economic practices is inadequate, proactive steps should be taken to adopt innovative practices.

Abstract: The present study reports the preparation and usage of Prosopis spicigera L. wood carbon-iron sulphide composite (PsLw carbon-iron sulphide composite) for the effective removal of Rhodamine 6G (Rh 6G) from aqueous solutions. The characterization of the adsorbent was made by FTIR, SEM, BET and potentiometric methods. The effect of the adsorption of dye was measured in terms of pH, contact time, initial concentration, temperature and in the presence of other ions. The batch and kinetic study were performed at pH=6.0. The maximum adsorption capacity is found to be 33.14 mg/g for an initial concentration of 20 mg/L at pH=6.0. The adsorption isotherm fits Langmuir isotherm and adsorption kinetics follows pseudo-second order model. Thermodynamic studies exhibit the adsorption to be feasible, spontaneous and endothermic in nature. Column analysis was evolved with Thomas model.

Keywords: Halon alternative, Fire safety, Aerosol, Pyrotechnic, Firefighting, Environment safety, Gas generator, Fire extinguisher
Abstract: In 1987, the Montreal protocol determined halon as ozone-depleting agent and subsequently, the U.S. Environmental Protection Agency (EPA) banned its manufacture. Thus, against the urgent background of this elimination of halons, research and development efforts in pyrotechnically generated hot aerosol as a fire extinguisher resulted as one of the significant halons substitute technology. Unlike conventional fire suppression agents, like halon, water mist, foam and inert gas, pyrogenic aerosol-based suppression agents do not require pressurized gases to drive out the suppression agent and are more efficient than haloalkane extinguishing agents and can extinguish class A, B, C, D and K fires at fire extinguishing concentration (FEC) of 30-200 g/m3. Moreover, the ozone depletion potential (ODP) and global warming potential (GWP) values of aerosol extinguishing agents are nearly zero. This has provided thrust for research and development units to research aerosol-forming composites for many defence and civilian applications, especially for effective operation in hard to reach areas, such as in aircraft hangar and airfield, ammunition storage, vehicle engine compartment, ship engine room, aircraft engine, electronic equipment bay and wing pods, etc. Here, the application of condensed aerosol-based fire extinguishers and real fire test scenarios conducted by the defence and civilian laboratories of various countries has been reviewed. In addition, some of the limitations and concerns, like thermal hazard, occupational hazard, corrosivity and toxicity associated with these systems have been discussed. Nevertheless, enhancement for a highly efficient, much cleaner and non-corrosive aerosol-based fire extinguishing agent is still desired.

Subject: Utilization of Construction and Demolition Waste in Self Compacting Concrete
Keywords: Recycled coarse aggregate, Water absorption, Construction and demolition waste, Old mortar, Self compacting concrete, Sulphate attack
Abstract: Recycled coarse aggregate and natural coarse aggregate are two different aggregate, one of aggregate consist of old mortar over it and that is recycled aggregate whereas natural aggregates are fresh. This paper presents results of an experimental investigation using construction and demolition waste, that is recycled coarse aggregate (RCA). The RCA was obtained from IL and FS Environmental Infrastructure and services Ltd., New Delhi. Due to the large construction activity, it requires to find the suitable material to replace natural material for manufacturing concrete. In this investigation influence of different quantity of RCA on self compacting concrete (SCC) in fresh and hardened state was undertaken. The properties obtained from SCC using RCA were compared with SCC having 100% natural coarse aggregate (NCA), that is control concrete. The NCA was replaced with RCA by a quantity of 20%, 40%, 60%, 80% and 100%. The fresh characteristic of SCC was investigated using slump flow test, V-funnel test and L-box test. The hardened properties obtained were compressive strength tests after 7, 28, 56 and 90 days of curing and tensile strength after 28 days of curing. It was observed from the result that fresh properties of concrete made with RCA changes slightly upto 40% and considerable changes was noticed above 40% as compared to concrete made with natural coarse aggregate due to high water absorption. In the hardened state results of different strength properties, show that upto 60% replacement level there is slight decrease in strength but above 60% it increases. Main disadvantage noticed from the research work was as increasing the percentage of RCA, water absorption also increases. Durability of SCC using RCA was observed by keeping the sample for water absorption test, alkalinity test and sulphate attack. The water absorption increases with increasing the RCA content.

Keywords: Water, Physico-chemical parameters, Water quality index
Abstract: The characteristics of water, air and soil having physical, chemical and biological changes are undesired changes. So, people around the world are under tremendous threat. Water is highly polluted day by day with different harmful contaminants. This is happening due to man-made activities, like increased human population, use of large amount of fertilizers and industrialization. natural water is contaminated due to leaching of soils, industrial processing, residential waste, municipal waste and weathering of rocks. Various water borne diseases occur in human beings due to use of contaminated drinking water. So, it is necessary that at regular time intervals the quality of drinking water should be checked. The availability of good water quality improves quality of life while prevent disease. So, for testing water quality different physico-chemical parameters were used for the calculation of water quality index.
