摘要
生活饮用水安全风险评估系统具有一定灰性,运用多维灰聚类理论,将生活饮用水毒理学指标中氟化物、铬、硝酸盐氮作为安全因子的3个评估指标,对2014年中部地区某市生活饮用水水质监测数据进行了安全风险综合评估.结果表明:中部某市生活饮用水不合格样本都属于低风险类型,符合实际情况.此法明确了生活饮用水毒理指标的安全风险等级,对中部某市生活饮用水的监管控制具有参考价值.
Based on the uncertainty characteristics of the safety risk assessment system on drinking water, a theory Of the multidimensional grey cluster was performed in monitoring data of drinking water in central China in 2014 to conduct comprehensive risk assessment. The toxicological indexes included fluoride, chromium and nitrate. The assessment results showed that the unqualified samples were almost low risk types, in line with the actual situation. The theory not only determines the risk of unqualified samples of toxicological indexes in drinking water, but also provides the reference value for supervision and regulation.
