摘要

中文摘要: 四川盆地饮水问题一直是人们关注的区域。本文以四川盆地典型山丘区名山区为研究对象，在调查区域饮水氮污染源、介水性疾病的基础上，采用USEPA推荐的健康风险评估模型对饮水和皮肤接触两种途径的水质健康风险进行了评价，利用ArcGIS10.0软件插值生成了健康风险空间分布图，结果表明：（1）部分农村饮用水中硝酸盐、氨氮含量超过《生活饮用水卫生标准》（GB5749-2006）中限值(10mg•L-1)，属轻度污染程；（2）硝酸盐、氨氮、亚硝酸盐的饮水途径非致癌风险明显高于皮肤接触途径非致癌风险，3种污染物的非致癌风险均小于风险可接受水平1，即不会对当地居民的身体健康产生慢性毒害效应，但硝酸盐污染需引起相关部门的重视；（3）硝酸盐、亚硝酸盐、氨氮的非致癌风险在空间上变化显著，且年际间的空间变异性较大。

Abstract

Abstract:Drinking water safety in Sichuan Basin is an important issue. Here

Mingshan District as a typical mountainous and hilly area in the Sichuan Basin was selected as the study area. Pollution sources of drinking water and waterborne diseases therein were investigated. Health risks arising from the exposure pathway of drinking and skin contact were evaluated by adopting the USEPA Health Risk Assessment (HRA) Model. Temporal and spatial variation characteristics of health risks with support of Geographic Information System(GIS) technology. The results showed that: (1) the contents of nitrate and ammonia were exceeded the upper limit of Standards for DrinkingWater Quality (GB5749-2006) in some of the rural drinking water sources; (2) the non-carcinogenic risk of skinexposure to nitrate

nitrite and ammonia was lower than the drinking water exposure’s

and the non-carcinogenic risk of nitrogen was all within the acceptable level 1

in another word

it would not harm the residents’ health; (3) the non-carcinogenic risk of nitrate

nitrite and ammonia varied relatively greatly at time and space.
