In the Shunde Area of Foshan, Pearl River Delta Economic Zone, 208 topsoil samples were collected from vegetable fields to measure the contents of copper, nickel, chromium, arsenic, lead, zinc, cadmium, and mercury. The results showed that the average concentration of all these eight heavy metals were higher than their background values of Guangdong Province.  According to the pollution evaluation, 21.7 percent of the study area is suffered from moderate and severe pollution, indicating the requirement of modifications in agricultural cultivation practices in these areas.
