| The Evaluation of Health Risks in Soils and Vegetables around an Industrial Area in South China |
| 100 samples of vegetables and 145 samples of soils were collected around an industrial area in south China. Their health risks were evaluated, and high lead pollution-tolerant vegetables were selected through calculating bioconcentration factors (BCF). Lead accumulation in soils was obvious. Lead concentrations of 135 soil samples exceeded the second level of Environmental Quality Standard for Soils promulgated by Chinese Government. Lead concentrations in vegetables were in the range of 1.41–303.10 mg?kg-1. According to Maximum Levels of Contaminants in Foods promulgated by Chinese Government, lead concentrations of all vegetable samples were above the limitation. Lead content of leafy vegetables was higher than that of gourd and fruit vegetables as well as rootstock vegetables. Lead bioconcentration factors of gourd and fruit vegetables were the lowest, while their lead pollution-tolerance was the highest. Rootstalk vegetables and leafy vegetables may pose a serious health risk to local residents. |
