Abstract: RCRA §1004(27) defines a solid waste as, "any garbage, refuse, sludge from a wastewater treatment plant, water supply treatment plant, or air pollution control facility, and other discarded material, including solid, liquid, semisolid, or contained gaseous material, resulting from industrial, commercial, mining, and agricultural operations and from community activities." It is essentially any waste material generated by human activity, though even animal waste can sometimes be included in it. It is usually low in liquid content, hence being termed as Solid waste.

Abstract: Vegetable oils obtained from fruits and seeds have a rather important part of the diet. They are some underutilized oilseeds species as Raphiahookeri. Physicochemical properties of oil extracted from Raphiahookerimesocarp was analyzed before and afterepoxidation reaction. The results showed that the extraction yield was 53.46%. The epoxidation reaction gave a conversion of 99.8% and a selectivity of 52.4%. Before epoxidation, refractive index, relative density kinematic viscosity, iodine index, acid index, peroxide index, saponification index, unsaponifiable......

Abstract: The recent paper underline the nowadays questions emerged and related with climate change, disaster displacement and migration. It's deal with people' vulnerability, consequences and legal framework. The newest researches suggest that half a billion people could be pushed into poverty as economies around the world shrink because of the coronavirus outbreak. Background: Risk is all around us. After the events of 2020, it's not surprising that the level and variety of risks we face have become more pronounced than ever. This is especially important for global risks that have a direct or indirect impact on the national security system, as a key element of the country' critical infrastructure. So the risk assessment became one of the most important.......

Abstract: The present study was done to assess the suitability of groundwater for portability and other consumption purposes. Seven different Physico-chemical parameters were taken into account to calculate the Water Quality Index (WQI) based on a recommended agency like the Bureau of Indian Standards (BIS) and the World Health Organization (WHO). The total alkalinity of groundwater in the Heeranagar village was observed higher. The mean value for parameter nitrate is 68 mg/L, and the standard deviation calculated is 15.13 which is higher than the BIS (IS 10500: 2012) acceptable limit of 45 mg/L. The mean value of the parameter fluoride for the assessment period is 1.64mg/L, and the standard deviation calculated is 0.49 which isalso higher than the acceptable limit. Due to higher concentrations of nitrate, fluoride, and higher the values of TDS, WQI is not excellent for the selected village sample source.

Abstract: Considering a global issue pertaining to impact of heavy metals on environmental components, this overview covers the action-packed progression of 'Bioremediation' at diversified level. An augmentation of heavy metal in water bodies alongwith the soil in close environs to industries making it lethal and for scheming it, bioremediation is brought into task including a sequence of processes, with the aid of metal resistance microorganisms, followed by accumulation of metal like Zinc, Cadmium and Arsenic. Moreover, amongst the microorganisms, capable of bioremediation of the major pollutant elements, namely, lead, cadmium, arsenic and mercury, encircling their individual allowable limits, in context to foods and beverages, Saccharomyces cerevisiae has been revealed to be an appealing preference.......
