[Accumulation Characteristics and Dietary Exposure Estimation of Heavy Metals in Vegetables from the Eastern Coastal Region of China].

The levels of six toxic metals and five essential metals in five groups of vegetables marketed in the eastern coastal region of China were analyzed using inductively coupled plasma mass spectrometry. The results showed that the concentrations of six toxic heavy metals in all the vegetables did not exceed the maximum residue limits. The health risk assessment indicated that consumption of vegetables may not pose a potential noncarcinogenic risk to consumers, while there is a carcinogenic risk level of 10-5 level from inorganic arsenic exposure through vegetable consumption. Additionally, a similar trend was observed for the accumulation of toxic and essential metals. Furthermore, compared with other vegetable groups, edible fungi have a high potential to accumulate toxic and essential metals, which indicates that pollution monitoring of edible fungi should be strengthened.
