Abstract

Investigation of the vegetable garden soil in Foshan City 4 kinds of heavy metals Cu, Pb, Zn and Cd in the total and different forms of content, while also investigating a variety of vegetables and edible part of the Cd content. The results show that, Foshan City, the heavy metal content in vegetable field exceed the national and the background value of Guangdong Province, the pollution index to the maximum Cd, Cu, followed by, Cd elements of the highest validity coefficients. Foshan City, edible part of vegetables found excessive Cd, leafy soil Cd content and Cd the full amount of exchangeable manganese content and the amount of state showed a significant positive correlation. The state of heavy metal content of vegetable soil in Foshan city was investigated. The total content and available content of 4 heavy metal elements (Cd, Pb, Zn, and Cu) were analyzed and measured. The result indicated that the heavy metal content of vegetable soil in Foshan city was greater than the average in other areas throughout Guangdong Province or even the whole country. The valid coefficient of Cd element was the greatest. The content of Cd in vegetables was greater than the state vegetable sanitation standard. In different kinds of vegetables, the content of Cd in leaf-vegetable had very significant correlation with the content of different sort Cd in soil. which indicated that the content of Cd in vegetables was affected by the content of Cd in soil.
