Among the phthalic esters, di-butyl phthalate (DBP) and di-2-ethylhexyl phthalate (DEHP), which are categorized endocrine disrupting chemicals, account toy up to 80％ of the world production. Nine phthalic esters were quantitatively determined in water and in sediment samples from Gawngyang Bay and Seomjin River estuary. This might be the first report in contamination of phthalates in the marine environment of Korea. DBP and DEHP were detected with the high concentration and high frequency, while the other phthnlic compounds were below the detection limits. The aveyage concentyations of DBP and DEBP in sediment from Gawngyang Bay were 33.8 ng g$^<$TEX>-1/ and 67.4 ng g$^<$TEX>-1/ on a dry weight basis, respectively. The concentrations in surface watey from Seomjin River estuary were in the range of 62.7∼333.8 ng L$^<$TEX>-1/ for DBP and 25.6 ng L$^<$TEX>-/∼116.1 ng L$^<$TEX>-1/ for DBHP. In sediments from Seomjin River estuary, DBP ranged 9.1∼149.3 ng g$^<$TEX>-1/, and DEHP 46.3∼156.3 ng g$^<$TEX>-1/. Phthalic esters concentrations found in Seomjin River estuary were much less than those in other rivers in Korea. Distribution pattern of DBP and DEHP concentrations in Seonliin River estuary indicates that both compounds aye introduced to Gwangyang Bay through run-off.
