某金矿区农田土壤重金属污染的人体健康风险
Human health risk under the condition of farmland soil heavy metals pollution in a gold mining area
摘要
Abstract
Human health effects of heavy metal pollution have constituted a major environmental problem at present. Mining activi-ties lead to different degrees of accumulation or excess of heavy metals in soil, groundwater and crops in a gold mining area. The di-etary structural parameters were obtained through sample collection and population exposure questionnaire. Based on the average con-tent of heavy metals in the sample and using human health risk assessment model recommended by USEPA, the authors calculated adult health risk probability derived from oral ingestion (soil, groundwater, wheat, corn, vegetables), skin contact (soil, groundwater) and other exposure pathways. The results show that there are unacceptably high non-carcinogenic risks and cancer risks that threat human health because of the existence of heavy metals pollution in the study area. The severer the heavy metal pollution in soil, the higher the human health risks. There are some important factors that harm human health, such as chromium in groundwater, mercu-ry in soil as well as vegetables and grains growing in polluted soil. Therefore, the following measures seem to be very important in protection of human health:to persuade local people not to drink groundwater with high chromium content and not to eat contami-nated crops, to remedy polluted soil, and to adjust crop planting structure.关键词
