Risk Assessment Method Of Drinking Water Under The Traditional Process

In view of various environmental problems caused by social progress, the quality of life for people demand are gradually improved. Drinking water is an indispensable resource in daily life and work for residents. We’ll pay more attention to water quality security issues, drinking water quality risk evaluation is imperative.Compose hazard identification for all kinds of pollutants possible in drinking water through the particularity of drinking water medium and follow the basic framework of the health risk assessment; We analyzed and compared the main exposure parameters in exposure assessment; People aslo made the final risks description and uncertainty analysis, discussed the health risks acceptance under the different routes of exposure for people who drinking water; Get a risk assessment and risk management model for population with different gender, age, lifestyle in drinking water pollution exposure, for the measured data of one given evaluated region we can make some extent analysis and find the corresponding conclusions of exposure risk; Improve water treatment technology provides a theoretical basis for the area according to their risk conditions of water quality.Due to differences in individual and behavior patterns, theoretically risk assessment of drinking water should be divided a variety of factors such as age, gender, and region in order to improve accuracy; The main route of exposure is drinking water exposure, so developing good habits of drinking water is very important, but cannot ignore the other forms as bathing, swimming, etc.; Try to use the exposure parameters which is more conformed with China’s national conditions to improve the accuracy of results;Contaminants in drinking water can not be fully understood limited to technical means,so the final health risk values can be seen as a theoretical minimum value from aconservative estimate;Uncertainty analysis is important in risk assessment for improving the reliability of evaluation and promoting the improvement of management.Risk evaluation of drinking water is a long-term unslack work, and during the study researchers still need to continue to strive for improvement.
