Abstract |
Occurrence of non-dioxin like PCBs (62 congeners) and indicator PCBs (7 congeners) were thoroughly investigated by analyzing a total of 210 food samples collected from 5 major cities in Korea. For the validation of the test method, extraction efficiency and cleanup patterns of multi-column for various food samples have been tested.
In food, the highest mean contamination level was observed in fish and fish derived products followed by eggs,milk and its products, and meat and its products. Most congeners of non dioxin-like PCBs were detected in food and T4CB and P5CB were the majors among them. In case of fish and shellfish, the indicator PCBs (#138, #153and #101, #118) were main congeners. Simple regression analysis between non-dioxin like PCBs (62 PCBs) and indicator PCBs showed strong correlation. The ratios of indicator PCBs (7 congeners) to non-dioxin like PCBs (62 PCBs) in each food groups were 29%-42% and the sum of the 7 indicator PCBs was on average close to two times higher than the sum of the non-dioxin like PCBs (62 PCBs) in animal origin food. |
