Several of the major incidents resulting in potential human exposures to polychlorinated dibenzodioxins (PCDDs) and/or polychlorinated dibenzofurans (PCDFs), polychlorinated biphenyls (PCBs) and related compounds which have occurred in the U.S. in recent periods have resulted from improper disposal of hazardous chemical wastes. Prominent examples of such environmental contamination episodes are...

Electronic waste recycling operations in some parts of Asia are conducted using rudimentary techniques which result in workplace and environmental contamination with toxic metals and persistent organic pollutants. This study reports concentrations of 14 polybrominated diphenyl ethers (PBDEs), from tri- to deca-brominated, in 31 samples of soil, sediment, dust or ash collected in the vicinity of...

Porcelain and plastic materials constitute bulk of household wastes. Owing to resistibility and slow degradability that accounts for higher residence time, these materials qualify as potential hazardous wastes. Retention of water permits these wastes to form a congenial biotope for the breeding of different vector mosquitoes. Thus porcelain and plastic wastes pose a risk from public health view...

Metal bioaccessibility is an alarming issue in croplands of mining sites due to overloading of toxic metals. Hence, the present study is aimed to determine the overloading of toxic metal in croplands across the Tawag village, Hutti, Raichur, India. Correspondingly, to identify the soil bacterial growth, physiological oxidative stress enzyme activity and surface macromolecular functional group e...

Healthy soils are essential for progressive agronomic activities. Organic fertilization positively affects agro-ecosystems by stimulating plant growth, enhancing crop productivity and fruit quality improving soil fertility. Soil health food security the key elements of Agriculture 3.0. Landfilling and/or open-dumping animal wastes produced from slaughtering cause environmental pollution releasi...

During the industrial processing of agricultural or animal products, large amounts waste are produced. These wastes, generated in throughout seasons year, can be considered most abundant renewable resources on earth. Due to availability and richness components these raw materials, there is a great interest their reuse, both from an economical environmental point view. This based fact that high ...

Supercritical CO2 fluid leaching (SFL) method using supercritical CO2 fluid containing a complex of HNO3 tri-n-butyl phosphate (TBP) was applied to removal of uranium from radioactive solid wastes. Sea sands, incineration ashes and porous alumina bricks were employed as matrixes of simulated solid wastes. Real radioactive incineration ash wastes and firebrick wastes were also subjected to the S...

conclusions considering the weight percentage of food wastes (70%), solid wastes of babolsar city could be used for composting. also as large quantities of infectious wastes were produced by hospitals of babolsar, it is recommended that sterilization systems (hydroclave) be used for decontamination of these hazardous wastes. materials and methods this study was a descriptive and cross-sectional...

Electric vehicles technology has been identified as being key in reducing future emissions and energy consumption the mobility sector The 90s have brought us to an era of environmental crisis. We are faced with problems air pollution, both indoor outdoor acid rain, water hazardous wastes, toxic landfills leaking storage tanks our soil, name a few. Our rapid advances into industrial technologica...

electronic wastes (e-wastes) is the most rapidly growing segment of the municipal waste stream. e- wastes comprise 2-5 percent of municipal solid wastes, including many different electronic products. iran is the biggest consumer of electronic products in middle east. approximately, 1.2 million computers are assembled in iran every year. there are more than 40 million active cell phones in iran....
