摘　　要：以五氯酚及其钠盐(统称为PCP)为研究对象,选择曾长期使用五氯酚钠杀灭钉螺的江苏省金坛地区为研究区域,使用膳食暴露模型计算评价了当地居民的人体暴露水平.结果表明,该地区成年人日均PCP摄入量最高值为8μg·d-1,该值低于世界卫生组织推荐的每日允许摄入量180μg·d-1;饮水和植物类食物是人体摄入PCP的主要途径,分别占总摄入量的42%和39%.此外,不确定性分析表明,模式运算结果呈偏态分布,偏度、峰度系数分别为3.51和19.7.Human exposure to pentachlorophenol and its sodium salt （generally called PCP was used as a molluskacide against oncomelania for a long time. The CalTOX Food inhabitants. The maximum adult average daily-intake of PCP in this city was 8 μg·d PCP） were studied in the city of Jintan, Jiangsu Province, where exposure model was used to assess the human exposure level of the , which was lower than the Acceptable Daily Intake （ADI） of 180 μg·d^-1 recommended by the World Health Organization （WHO）. Drinking water and vegetables were the main sources for human intake of PCP, accounting for 42% and 39% of the total PCP intake, respectively. The influence of uncertainties of input parameters on the model results was studied by uncertainty analyses, which indicated that the calculated outputs of the model showed a skewed distribution, where the coefficients of skewness and kurtosis were 3.51 and 19.71, respectively.
