Abstract
Gwangyang Bay located in the southern coast of Korea is a semi-enclosed embayment including a big steel mill plant and petroleum refinery plant complex around the bay. Organic toxicants of PAHs, PCBs, DDTs, Hexachlorocyclohexane (HCH), chlordane (CHL), butyltins (BTs), alkylphenols (APs) and phthalate esters (PHs) in surface sediments were quantitatively analyzed. Among the toxicants, PAHs showed the highest concentration in the range of 87 – 9436 ng/g on a dry weight basis. Relatively higher PAH concentrations were found in the creek sediments. Total PCB concentrations were higher in the creek (1.78 – 24.2 ng/g) than in the bay (0.61 - 2.20 ng/g). Organochlorine pesticides demonstrated similar concentration ranges of 0.14 – 6.20 for DDTs, 0.09 – 0.83 for HCHs, ND - 2.60 ng/g for CHLs in both the creek and the bay. Total butyltin concentrations in the bay sediment ND – 54 ng/g, which are lower end of the butyltin levels in surface sediments found in Korea. Among the eight alkylphenols and bisphenol A, nonylphenol and less extent octylphenol were major phenolic compounds in the bay sediment with the range of not detected – 74.3 ng/g. Diethylhexyl- and dibutyl-phthalate were only detected in the bay sediment among the 11 phthalate analytes including diethylhexyl adipate. Relatively high concentrations of PHs were found at Sts. 12 and 22 near the mouths of Sueo River (270 ng/g) and Seomjin River (501 ng/g).
