摘要

Supervision of urban water source area and the safety of drinking water is one of the important tasks in China9s current environmental protection work. By reviewing screening methods of characteristic pollutants in urban water source area, screening system of pollutants based on the framework of environmental risk is introduced in detail ： establish database of pollutants→determine the evaluation purpose→determine testing end and screening standard→assignment calculation→prioritization. At the same time, the application of health risk assessment and technology in the risk assessment of urban water source area is introduced, so as to provide technical support and theoretical basis for management and protection of urban water source area.
