摘要
水质安全是饮用水安全的重中之重,直接关系到人体健康。健康风险评价将环境污染物与人体健康效应联系起来,以致癌风险和危害指数分别反映污染物对人体的致癌危害和非致癌慢性毒害作用的程度,定量评价饮用水水质对人体健康的影响,为饮用水水质安全管理提供更深入的科学依据。依据健康风险评价的结果,能够更加科学合理地指导水源地管理、饮用水处理技术的选择以及水质的分级风险控制。
Drinking water quality impacts people＇s health directly, so quality safety is the most important part in drinking water safety, Heahh risk assessment can evaluates impacts of water quality on human body, which assesses carcinogenic and non-carcinogenic hazard of contaminants in drinking water represented by cancer risk and hazard index respectively, so it can provide more deeply scientific support for quality safety management on drinking water. Based on health risk assessment, risk management mode will be introduced to administer water source management, selection of drinking water treatment technique and hierarchical risk administration on water quality.
