中文摘要: 摘要：本文以云南省昆明市东川主要河流及附近土壤、植物为研究对象，并对其进行采样分析，并根据美国环境保护署（US.EPA）推荐健康风险评价方法对东川流域多种环境因素进行了重金属的健康风险评价。结果表明，水环境中致癌物质造成的风险最大，风险值在2.35-8.27×10-4之间， 达到U.S.EPA推荐的最大值10-4，植物根部的健康风险值为0.40-7.00×10-1，茎叶部分的风险值为2.42-15.24×10-2，根部存在的重金属对人体的健康风险约为茎叶部分的5倍；土壤中非致癌物质的健康风险影响较大，健康风险值区间为0.63-3.50×10-1。
Abstract:Abstract: Water, plants and soil samples in the domain basins of Dongchuan, Yunnan Province were collected, investigated and analyzed. And health risk assessments of heavy metals in these environmental factors were conducted according to the U.S.EPA health risk assessment model. Results show the largest health risk was found to be carcinogenic risk (2.35-8.27×10-4 ) in aquatic environment, which has achieved the maximum level recommended by EPA(10-4). Considering the risk levels in the roots(0.40-7.00×10-1) and stems(2.42-15.24×10-2) of plants, health risk levels of heavy metals in roots were about 5 times higher than in stems. In soil, non-carcinogenic risks levels (0.63-3.50×10-1)were found larger than carcinogens.
