在线生物毒性监测系统在饮用水源地水质监测中的应用

摘要

The dosage effect was analyzed on biotoxicity of Hg, Cd, Cr, Pb and As, to evaluate the early warning function of biotoxicity monitoring method on water quality monitoring of drinking water source.It showed that the biotoxicity rank was Hg>As>Pb>Cd>Cr.Combined with the biotoxicity data of Dam water source of Nanjing, the dynamic alarm limit was established to evaluate the water quality.%通过对汞、镉、铬、铅和砷的生物毒性剂量效应分析，评估生物毒性监测方法在饮用水源地水质监测中的预警作用，结果显示，几种元素的生物毒性大小依次为：汞＞砷＞铅＞镉＞铬。结合南京上坝饮用水源地的生物毒性监测数据，建立动态报警限，用于评价水质安全。
