Health and Ecological Risk Assessment of Heavy Metal Pollution in Esfarayen Surface Soils
Introduction: Due to the continued urbanization and industrialization in most parts of the world, metals are constantly being introduced into the soil environment and posing a major threat to human health. The purpose of this study was to investigate the contamination of Esfarayen surface soils with heavy metals and its hazards to human health. Methods: Surface soil samples were collected from ...
متن کاملPotential ecological risk assessment and prediction of soil heavy-metal pollution around coal gangue dump
The aim of the present study is to evaluate the potential ecological risk and trend of soil heavymetal pollution around a coal gangue dump in Jilin Province (Northeast China). The concentrations of Cd, Pb, Cu, Cr and Zn were monitored by inductively coupled plasma mass spectrometry (ICP-MS). The potential ecological risk index method developed by Hakanson (1980) was employed to assess the poten...
متن کاملEnvironmental Assessment of Heavy Metal Pollution and Human Health Risk
Heavy metals are normally occurring elements that have a density at least 5 times higher than of water. Their plentiful domestic, industrial, agricultural and technological usages have led to their widespread distribution in the environment; raising worries over their possible impacts on human health and the environment. The toxicity of heavy metals relies on numerous factors including the dose...
متن کاملSoil Heavy Metal Pollution and Risk Assessment in Shenyang Industrial District, Northeast China
To investigate the soil heavy metal pollution characteristics and ecological risk factors, 42 samples and six typical soil profiles were collected from the Shenyang industrial district in northeast China and were analyzed for contents of titanium (Ti), copper (Cu), lead (Pb), zinc (Zn), cobalt (Co), nickel (Ni), chromium (Cr) and arsenic (As). Through statistical analysis, it was found that the...
متن کاملEffects of heavy metal pollution on the soil microbial activity
The effects of heavy metals on soil microbial processes were investigated over a period of six weeks. Analytical grade (Sigma) sulphate salts of copper, zinc and nickel were added individually and in combinations to soil samples and incubated in different plastic pots. Samples were taken from the pots forthnightly and the rates of microbial carbon and nitrogen mineralization, microbial biomass ...
