Abstract: To get the general knowledge of heavy metals pollution in vegetables in Hangzhou as well as their health risk， the heavy metal contents in vegetables cultivated in main vegetable bases in Hangzhou were investigated. It was shown that the contents of heavy metals were relatively high in leafy vegetables， root vegetables and eggplants， yet were relatively low in allium vegetables， melons and leguminous vegetables. The main sources of heavy metal pollution in root vegetables and eggplants were joint\|contamination of Pb， Cd， Cr and Pb， respectively. The leafy vegetables were safe in general， but a few species reached the warn level or exhibited slight pollution due to the joint contamination of Cu， Zn， Cr or Pb and Cr. The allium vegetables， melon and leguminous vegetables were still within the clean level. Based on health risk assessment， As， Cu and Cr were the chief threats to local residents.
