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.
The drinking water safety risk assessment system has a certain degree of grayness. By using the multi-dimensional gray clustering theory and using the fluoride, chromium and nitrate nitrogen in drinking water as the safety factor, City drinking water quality monitoring data to conduct a comprehensive assessment of safety risk.The results show that: a city in the city of drinking water non-conforming samples are low-risk type, in line with the actual situation.This method of life drinking water toxicological indicators of safety risk level , The central city of drinking water regulation and control of a reference value.
