Risk Assessment for Petroleum Contamination Exposure in Groundwater

This paper presents a human health risk assessment approach based on fuzzy transport simulation (HHRA-FTS) to create the response relationships between contaminants transport and human health. Compared to the conventional methods, HHRA-FTS employs the fuzzy transport simulation to model the concentration and fate of contaminants, and takes into account different exposure pathways of pollutions in risk assessment. It has the advantage of avoiding miscalculation of results in terms of giving an interval values for the concentration of contamination by the fuzzy simulation. The HHRA-FTS approach is applied to a real-world PH-contaminated groundwater system in Pinggu County, located in northwest of Beijing, China, for demonstration studies.
