Abstract
This paper reviews the extent of heavy metal contamination in Chinese vegetables. Increasing amounts of heavy metals are discharged into the environment in China. Metals such as cadmium and lead have become major contaminants, as well as chromium and mercury to a lesser degree. Factors influencing heavy metal contamination in vegetables and their control in China are analyzed and discussed.
