Screening method and application of characteristic pollutants in river basin water based on carcinogenic risk

Abstract

The invention relates to a river basin water body particular pollutant screening method based on carcinogenic risks and an application thereof and belongs to the field of environmental sciences and health risk assessments. According to the river basin water body particular pollutant screening method based on the carcinogenic risks, pollutants in a plurality of water environment pollutant lists serve as candidate particular pollutants, a two-stage factor comprehensive scoring method is utilized to comprehensively take information of pollutant carcinogenic grade, environmental pollution status, emission intensity of pollution sources and the like into consideration, quantitative scoring is performed on 10 factors such as times of ultra standard of surface water, surface water over standard rate, overall detection rate of the pollutants and environmental medium universal detection rate of the pollutants, screening is performed according to total scores and a final particular pollutant list is determined. The river basin water body particular pollutant screening method based on the carcinogenic risks provides reference pollutant objects for environment management departments to take targeted treatment measures and carry out targeted environmental health monitoring work and has significant scientific significance and a practical value for reducing environmental carcinogenic risks of population in an object region.

Description

technical field [0001] The invention relates to the fields of environmental science and health risk assessment, and is a method for screening characteristic pollutants and its application, more specifically, a method for screening characteristic pollutants in river basin waters with an eye on carcinogenic risk control of crowds. Background technique [0002] With the increasing pollution of river basin water and the improvement of awareness of protecting river basin water, the demand for monitoring and treatment of water pollutants in related river basins is becoming increasingly urgent. However, water pollutants are becoming more and more complex. The pollutants entering the water have the characteristics of various types, wide pollution areas, and strong toxicity. It is impossible to formulate standards for each pollutant and implement control. Some key pollutants should be controlled. Among the many pollutants, it is necessary to develop a screening method to screen out ...
