为评价农村居民饮用水中微量金属的暴露水平，采集了中国8个省222份农村饮用水样品，采用电感耦合等离子体质谱仪（ICP-QMS）分析了其中18种微量金属。基于金属浓度，计算健康风险评估，如慢性每日摄入量（CDI）和危害商数（HQ）。结果表明，青海、云南、湖南等地的饮用水中大部分重金属含量较低，总体水质较好，但As、Pb、Zn等重金属含量高于世界卫生组织（WHO）和中国饮用水标准。CDI和HQ值表明，中国农村居民饮用水的健康风险可以忽略不计。然而，青海省饮用水中高浓度的砷将对当地居民构成严重的风险。Zn、Pb、As含量应引起重视和深入研究。
In order to assess the exposure of rural residents to trace metals via drinking water ingestion, 222 drinking water samples of rural areas from 8 provinces in China were collected and 18 trace metals analyzed by inductively coupled plasma mass spectrometer (ICP-QMS). Based on metal concentrations, the health-risk assessment such as chronic daily intakes (CDI) and hazard quotient (HQ) were calculated. Results showed that most metals occurred in the drinking water at very low concentrations, indicating a general good quality, while the concentrations of As, Pb and Zn in some samples from Qinghai, Yunnan and Hunan provinces were higher than World Health Organization (WHO) and Chinese guidelines for drinking water. The values of CDI and HQ indicated a negligible health risk for most Chinese rural residents via drinking water. However, high concentrations of As in drinking water from Qinghai province would pose a serious risk to the local inhabitants. More attention and intensive study should be paid to Zn, Pb and As contents.
