risk assessment of hazardous impacts on urbanization and industrialization activities based upon toxic substances

Risk assessment of hazardous impacts on urbanization and industrialization activities based upon toxic substances

A risk assessment study was conducted to predict the expected hazardous influence on the ecosystem resulted from urbanization and industrialization activities at Helwan area, Egypt. To achieve these goals, soils, plants and water samples were collected from Helwan area, and their total concentrations of inorganic contaminants (Cd, Cr, Co, Cu, Fe, Mn, Ni, Pb, and Zn) and organic pollutants; such...

It is needless for occupational health doctors and scientists to mention about the importance of risk assessment of hazardous substances used in workplaces. Since the US Supreme Court sentenced the " benzene verdict " requiring better ground for the occupational exposure limit (OEL) for benzene in 1980, the research and scientific knowledge on risk assessment for hazardous substances have been ...

Regionally Based Assessment of Persistent Toxic Substances

Impacts of Forest-Based Activities on Woodland Characteristics

The purpose of this study was to investigate the impacts of forest-based activities on the conditions of the Ganaveh woodland in the southern Zagros, Iran, and to suggest strategies for improving the implementation of forest resource management plans. Woodland inventory data was gathered in 2003, accompanied with data from interviews in 2008, were used in this study. The results show that there...

Advisory Committee on Hazardous Substances

I. Review information and studies on the environmental exposure and effects of nanoparticulate silver; II. Comment on known or predicted environmental exposure levels and whether these present a human health or environmental risk; III. Comment on the nature of appropriate measures to minimise risks, if these are felt to be necessary at this point in time; IV. Consider what action should be take...
