Abstract:Pollution of the 15 PAEs by oral media including groundwater, soil, crops, in a total number of 346 samples in Taihu Lake Basin (southern Jiangsu) include Wuxi, Changzhou and Zhenjiang City was analyzed. Four-step health risk assessment recommended by US EPA combined with the measured exposure parameters were used to scientifically evaluate Taihu lake basin residents by the oral way PAEs health risks. The results showed that the basin by oral medium except some vegetables had detected PAEs, the higher proportion of PAEs in groundwater, soil, staple food include rice and wheat, vegetables include lettuce, leeks, eggplant, soybean, potato vine, Malabar Spinach, asparagus bean, amaranth, peppers, spinach, cucumber, pumpkin vine were DNP, DCHP, DBP, DNP. PAEs by oral exposure risks was 4.88×10-5 for male, and was 4.29×10-5 for female, and DEHP had maximum contribution rate. Males PAEs exposure by oral health risks was greater than females, in summer and autumn risks of PAEs by oral exposure for male was equal to the spring and winter, in spring and winter risks of PAEs by oral exposure for female was greater than in the summer and autumn. The risk of basin population by oral exposure was higher than the acceptable health risk level of 1×10-6 recommended by the Royal Society, but lower than the acceptable health risk level of 1×10-4 recommended by the U.S. Environmental Protection Agency.
