| 摘 要： | 砷(As)是一种持久性、毒性强的致癌污染物。近年来我国As污染事件频发,故制定As的人体健康水质基准具有重要意义。以辽河铁岭段为研究对象,采集并分析水样和不同营养级的鱼样中As含量。结合文献调研,确定As的污染物毒性参数与辽河铁岭段饮水相关的部分人群暴露参数;基于线上问卷调查,计算本地居民人均第2、3、4营养级鱼类摄入量分别为0.0268,0.0323,0.0027 kg/d,进而推导出当地代表性鱼类As的第2、3、4营养级国家生物累积因子为8.256,9.281,10.197 L/kg。根据以上参数计算出辽河铁岭段As的人体健康水质基准值为1.976×10-5 mg/L,研究结果可为辽河流域制定水质标准提供参考,为更加科学有效地管控污染物排放和保护人体健康提供依据。

| Abstract: | Arsenic is a persistent and toxic carcinogen pollutant.In recent years,arsenic pollution incidents occur frequently in China.It is of great significance to establish human health water quality criteria for arsenic in China.Taking the Tieling Section of Liaohe River as the research object,the content of arsenic in water samples and fish samples of different nutritional levels were collected and analyzed.Combined with literature research,the toxicity parameters of arsenic pollutants and the exposure parameters of some people related to drinking water in the Tieling Section of Liaohe River were determined.Through the online questionnaire survey,it was calculated that the per capita fish intake of the second,third,and fourth nutritional levels of local residents was 0.0268,0.0323,and 0.0027 kg/d.Then it was derived that the second,third,and fourth trophic national bioaccumulation factors were 8.256,9.281,and 10.197 L/kg of local representative fishes.According to the above parameters,it was calculated that the reference value of human health water quality criteria of arsenic in the Tieling Section of Liaohe River was 1.976×10-5 mg/L,which provided a reference for the formulation of water quality standards in Liaohe River Basin,and a basis for scientific and effective pollution control and protection of human health. |
