高虹镇稻米中重金属污染状况及健康风险评价
Heavy metal pollution in rice of Gaohong Town with a health risk assessment
摘要
Abstract
To assess the heavy metal contamination in rice and human health risks induced by rice consumption in Gaohong Town, Zhejiang Province, 51 local and 37 commercial rice samples were collected and analyzed for heavy metal concentrations. This was followed by a pollution index calculation, correlation analysis, and cluster analysis. In addition, potential health risk through rice consumption was evaluated using a hazard index (IHI) based on the data and questionnaire surveys. Results showed that rice samples were contaminated by Cr, As, and Pb in Gaohong Town with concentration ranges of 0.03-13.45 mg·kg-1 for Cr, 0.01-1.64 mg·kg-1 for As, and 0.04-7.84 mg·kg-1 for Pb. Of the rice samples that exceeded the National Food Safety Standard, 70.59%were Cr, 31.37% were As, and 27.45% were Pb. The comprehensive pollution index of local rice reached 3.01, which implied a moderate pollution level. By comparison, the pollution index of commercial rice from external sources was 1.95, meaning a mild pollution level. The IHI value of local rice samples was 3.50, and for market rice samples it was 2.18. Thus, the overall health risk from heavy metals induced through local rice consumption was higher than commercial rice.关键词
