Assessment for Environmental Health of Small-scale Water Supply Source Based on Triangular Fuzzy Technology
Employing the triangular fuzzy technology, the article establishes a health risk assessment model for small-scale water supply source. By using this model not only the value of probable risk indexes of specific substance influencing peoples health but also their corresponding membership degrees (or relative confidence levels) can be obtained. The model is applied to assess the environmental health risk of the small-scale water supply source in Southwest of China. The result shows : the cancerous risk indexes caused by As and the total risk reach 2.014.05 X 10~4a-land 2.19-4.14 X 10-4a-1 respectively, exceeding the acceptable levels recommended by lCRP (5.0X10-5a-1); the non-cancerous risk indexes caused by all pollutions arel.58-3.36X10-8a-1, less than the acceptable levels recommended by ICRP. The research shows that it is feasible to assess water health risk by the triangular fuzzy technology.
