摘要
为研究宁夏清水河汛期水环境健康风险,2012-2016年5月在清水河7个典型断面进行了水样采集和水质检测,综合考虑各种饮水途径,对流域上游周边男童的饮水和饮食进行抽样问卷调查和实际测量,研究获得当地男童夏季饮水摄入率,并对清水河水环境污染物通过各种饮水途径对男童所致健康风险进行了研究。结果表明:(1)化学污染物通过各种饮水途径所致健康风险特点均为:城市男童>农村男童,致癌物>非致癌物,总液体摄入>直接饮水>间接饮水;(2)不同男童群体饮水摄入率受区域、城乡、饮食、生活习惯等影响而存在明显的差异性,并在同一污染背景下,不同男童群体所受健康风险水平和构成主要取决于其饮水摄入率;(3)12种化学污染物通过总液体摄入途径所致健康总风险的数量级在10-6/a^10-5/a之间,整个流域水环境质量总体上在逐年好转,下游为重点控制区域,泉眼山为重点控制断面。
In order to study the water environment health risk of Qingshui River in Ningxia during the flood season, water sample collection and water quality detection are carried out in seven typical sections of Qingshui River in May from 2012 to 2016, taking into account various drinking water pathways, a sample survey and actual measurement are carried out on the drinking and diet of boy in the upper reaches of the basin so as to study the summer drinking water intake rate of the local boy, and the health risk from chemical pollutants is studied by using boys as subjects. The results show： ①The characteristics of health risk from chemical pollutants through various drinking water pathways are ： urban boys〉 rural boys, carcinogens〉non-carcinogens, total fluid intake〉direct drinking water〉indirect drinking water. ② The drinking water intake rate of different boys is obviously affected by urban and rural areas, diet and living habits. Under the same pollution background, the level of health risks and composition of different groups of boys mainly depend on their drinking water intake rate. ③The total health risk of 12 chemical pollutants passing through the total fluid intake pathway is in the order of 10^（-6） ～ 10^（-5）/a, and the water quality of the entire basin is generally improved year by year. The downstream is the key to control. In the area, Quanyanshan is the key control section.
