DDTs are still potential hazard chemicals due to the properties of POPs, even though they have been banned in Korea since the 1970s. To assess pollution levels of the sediment we analyzed DDT isomers of 109 sites in 39 major lakes in Korea. For this assessment, we used sediment quality guidelines, analyzed the relationship of total DDTs concentration to particle size and total organic carbon concentration, and estimated the time when the DDTs came into the sediment by analyzing the isotopic composition ratio of total DDTs. Analysis Results are, the total DDTs concentration in the range of N.D.(<0.2 ng/g-dw)~14.6 ng/g-dw (2.32 ± 2.34 ng/g-dw) was similar to the study result of rivers in Korea and was relatively lower than the study result of rivers in other countries. Pollution assessment results showed that there were no sites exceeding probable effect concentration(PEC), but Chuncheon 2, Chuncheon 3 and Boryeong 3 sites exceeded the threshold effect concentration(TEC).The DDTs concentrations were not associated with particle size while it showed a correlation with total organic carbon(p<0.05). Isotopic composition ratio analysis, showed relatively recent influx of DDTs in to the Boryeong 3. Considering this result, the sites that the DDTs exceeds the TEC should be checked for impact on benthos or human health, accordingly assessing the improvement of sediments in the sites. Also, is necessary to investigate areas surrounding the sites. The sediment quality guideline used for this study is based on toxicity data from other countries. It is expected that the follow-up study would establish the data base of DDTs concentration in sediment and the toxicity on the benthos inhabiting the Korea, providing the base to develop guidelines reflecting Korean sediment quality and ecosystem.
