퇴적물에서 어류체내로의 DDT, DDE 이동예측과 위험평가

Abstract

The health risk was assessed for human population exposed to DDT and DDE by consuming fish dwelling in a contaminated aquatic environment. Aquaweb model was used to estimate the body burden of DDT and DDE in hairtail (Trichiurus lepturus) and red seabream (Pagrus major) with the conceptual foodweb model. The body burden of pollutants varied depending on the fish species and the other environmental parameters. We assessed the ecological risk for these fish by calculating No-Observed-Adverse-Effect-Level based Toxicity Quotient (NOAEL-TQ). The carcinogenic risk and noncarcinogenic hazard indices (HI) for human population also varied widely with environmental conditions. Better understanding on the trophic transfer of contaminants in the food web would be necessary for the construction of ecosystem model for the management of contaminated sediments.
