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...

Regionally Based Assessment of Persistent Toxic Substances

Semi-quantitative risk assessment of health exposure to hazardous chemical agents in a petrochemical plant

Background: Chemical contaminants present in the work environments include gases, vapors, and solid and liquid suspended particles. The number of factories producing chemicals has increased significantly. Each year, new products are introduced into the market. Consequently, the number of employees at risk of exposure to these materials is increased. Hazardous chemicals are used in the petrochem...

Risk Assessment of Occupational Exposure to Cement Respirable Particles and Crystalline Silica in a Cement Factory

Introduction: Cement factory workers exposure to airborne particles containing crystalline silica in Portland cement chemical compound can caused pulmonary diseases, including silicosis and lung cancer. The aim of this study was to assess the risk of occupational exposure to respirable cement dust and crystalline silica in a cement factory in Khorasan Razavi province. Methods: In this cross-se...
