Abstract

|
|
Periodic sampling and analysis were done of consumer tap water in a model region of the radius of 3㎞ within Daehwa industrial complex in Taejon Meteropolitan City. Based on this analysis, a probabilistic risk analysis for the ingestion and inhalation of hazardous pollutants in drinking water was made by using Crystal Ball. From the analysis, the 95th percentile cancer risk by chloroform and bromodichloromethane is estimated to be 1.0×10-4 and 9.8×10-5 for men and women, respectively. This percentile risk for either men or women is higher than a risk standard of 10-5∼10-6. If a risk standard of 10-5 is assumed to be acceptable, then the cancer risk for about 60% of men and about 55% of women in the model region exceeds the risk standard.
The meaning of the study results is more or less restrictive because of limited concentration data and other input data. However, the study shows explicitly that the probabilistic risk analysis is more advanced approach to get a real picture of risk and provides much more useful information to risk managers and the public.
