摘　　要：新冠肺炎疫情期间,选取12个水库型饮用水水源和4个河流型饮用水水源作为研究对象,采用发光细菌法监测了生物毒性,通过单因子法评价了毒性级别和安全性。结果表明:两种类型饮用水源的生物毒性相对发光值变化范围为77%~115%,绝大多数集中在90%~100%之间;从生物毒性平均值来看,相对发光值范围为88%~98%,无毒级(相对发光值>90%)饮用水源13个,低毒级饮用水源3个。During the epidemic of COVID-19,12 reservoir-type drinking water sources and 4 river-type drinking water sources were selected as the research objects in order to monitor the biological toxicity by the luminescent bacteria method,and evaluate the toxicity level and safety by the single factor method.The results show that the relative luminescence value of the biological toxicity of the two types of drinking water sources varies from 77%to 115%,most of which are between 90%and 100%.The relative luminous value of average bio-toxicity is between 88%and 98%.There are 13 non-toxic grade(relative luminous value>90%)drinking water sources and 3 low-toxic grade drinking water sources.
