简介
Heavy metal pollution in peri-urban areas in China is serious and complex. We thus developed an integrated evaluation method to assess heavy metal pollution and potential health risk to residents in a typical peri-urban area with diverse anthropogenic emission sources and cropping systems. Ecological risk was evaluated using Nemerow's synthetical pollution index (P n) and Potential ecological risk index (RI). Then polluted areas and responsible emission sources were identified by GIS mapping. Health risk caused by food intake and soil exposure was calculated by accounting for the influence of anthropogenic emissions and cropping systems. Agricultural soils in the study area were polluted by cadmium (Cd), mercury (Hg), lead (Pb), and arsenic (As). High concentrations mainly occurred near the mining area and along the roadsides. The accumulation of heavy metals in crops followed the order of tea leaves …
