THE NATIONWIDE MONITORING OF PAHS AND OCPS IN SURFACE SEDIMENTS FROM THE FOUR MAJOR RIVER BASINS IN KOREA
We analyzed micropollutants contamination (13 organochlorine pesticides OCPs and 16 polycyclic hydrocarbons PAHs) in sediments from major 4 river basins in Korea and tried to investigate the source identification of these contaminants. The ∑PAHs concentration in river sediments ranged from ND to 1756 ng/g and the average values of Han river, Nakdong river, Yeongsan river and Geum river were 103.3±300.1, 66.6±167.2, 44.1±44.3 and 50.5±49 ng/g-dry, respectively. The highest ∑PAHs concentration was detected near the petro-chemical factories. Particularly, 3- and 4-ring PAHs (Phenanthrene, Fluoranthene, Pyrene, Benzobfluoranthene, Chrysene, Benzoaanthracene, Anthracene and Benzokfluoranthene) were most abundant. ∑PAHs concentration in sediments from the lake was higher than those from river. The average concentration of ∑PAHs in lake samples was 205.4 ng/g ranging from 4.0 to 2,987 ng/g-dry. The ∑DDTs concentration ranged from ND to 9.04 ng/g-dry with an average 1.03±0.69 ng/g-dry. p,p- DDE was dominant compound and accounted for 61％ of DDTs.
