摘要
由于饮用水是人体暴露于有毒物质的重要暴露源,因此饮用水的安全对人体健康至关重要.为了定量描述饮用水中污染物对暴露人群所造成的危害,需要针对饮用水的健康风险评价做水质数据基础研究.以校园宿舍楼内生活饮用水配水支管为研究对象,对管网末梢水质进行了感官性状指标、一般化学指标及细菌学指标的研究分析,研究表明滞留水(在自来水水管中滞留6h以上的自来水)是对人体健康影响最大.研究作为饮用水健康风险评价的前期工作,为其在校园饮用水安全的进一步发展提供了基础性的数据.
Since drinking water is an important source of exposure for humans to be exposed to toxic substances,its safety is essential to human health.Many factors affect the quality of drinking water.To quantify the harm caused by water contaminants on the exposed population,you first need to get water quality data for the health risks of drinking water evaluation.Firstly,researchers need to study about water quality data for the health risk assessment.The experiments have found that the water for the campus life are affected by the quality of imported water,pipe materials and secondary water supply facilities.
