Abstract

In order to reveal the influence of harmful substances in reclaimed water quality on human health, this paper carries out the research from the perspective of risk assessment. Firstly, according to reclaimed water reuse applications and water quality requirements, the characteristics of its safety evaluation were analyzed and summarized. Then deducing risk scenario and analyzing the consequences to determine the risk transfer path of reclaimed water reuse, and the framework of water safety evaluation index system was put forward based on the result. Finally, by combining the traditional risk assessment theory and the USEPA’s four-step method with the characteristics of human health risk for reclaimed water, the procedure and model of human health risk assessment for reclaimed water were established.
