소각로 인근에서 재배되는 농산물의 다이옥신류 모니터링 및 위해도 평가에 관한 연구 = A Study on Risk Assessment and Dioxins Monitoring of Agricultural Products Produced near Incinerators

다국어 초록 (Multilingual Abstract)

Dioxins(PCDDs; Polychlorinated dibenzo-p-dioxins, PCDFs; Polychlorinated dibenzofurans) are accumulated in the body through the food as a representative environmental pollutants. Dioxins are flowed into the environment through the incineration of chemical products and electrical products containing PCBs. Dioxins generated from incinerators can pollute the atmosphere and soil, and it were accumulated in the body through food. Therefore, the dioxins monitoring of agricultural products produced near incinerators are required to ensure the safety of agricultural products. In this study, the analysis of dioxins was carried out on the basis of the law of the U.S Environment Protection Agency (EPA) Method 1613 and Korean Food Standards Codex Method SOP. The fifty agricultural products were collected in the field around the incinerators. As a result, the concentration range of detected dioxins was (0.0507~0.5824) pg/g. In the range of concentrations that reflect the toxic equivalent factor is (0.00002~0.01631) TEQ pg/g. The contribution of agricultural products to the dioxins intake is not equally distributed: tomato (74%), Corn (15%), Cabbage (9%), Green pepper (2%), red pepper (0.04%), Blueberries (0.0006%). The estimated daily intake of Korean Population through agricultural products was 0.00430 pg TEQ/kg body weight/day, and it was estimated at about 0.11% of tolerable daily intake(TDI) of Korea. Consequently, Dioxins exposure levels of agricultural products produced near incinerators has been found to be very safe.
