Abstract

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$\^$-1/ and 67.4 ng g$\^$-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$\^$-1/ for DBP and 25.6 ng L$\^$-/∼116.1 ng L$\^$-1/ for DBHP. In sediments from Seomjin River estuary, DBP ranged 9.1∼149.3 ng g$\^$-1/, and DEHP 46.3∼156.3 ng g$\^$-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.

광양만과 섬진강 하구에서 내분비계장애물질의 일종인 프탈레이트 화합물의 분포 특성을 국내에서는 처음으로 연구하였다. Di-butyl phthalate (DBP)와 di-2-ethylhexyl phthalate(DBHP)를 비롯한 9종의 프탈레이트 및 adipate를 분석 대상으로 선정했다. DBP와 DEHP가 가장 높은 빈도와 농도로 검출되었으며, 다른 화합물은 거의 검출되지 않았거나 검출한계 이하였다 광양만 표층퇴적물에서 DBP와 DEHP의 평균 농도는 각각 33.8 ng g$^{-1}$와 67.4 ng g$^{-1}$이었다. 섬진강 하구에서는 표층수에서 DBP가 62.7∼333.8 ng L$^{-1}$농도 범위로 검출되었으며, DEHP는 25.6∼l16.1 ng L$^{-1}$ 범위로 검출되었다. 섬진강 및 하구 표층 퇴적물 시료 중의 DBP의 농도는 9.1∼149.3 ng g$^{-1}$, DEHP는 46.3∼156.3 ng g$^{-1}$으로 검출되었다. 광양만에서 DBP와 DEHP는 공단 일대와 생활 하수가 배출되는 하천 주변부에서 높은 농도를 보였으며, 광양만 외해로 갈수록 농도가 적어지는 경향을 보였다. 섬진강에서는 안쪽에서 높은 농도를 보이다가 서서히 감소하지만 일부 정점에서 높은 농도로 검출되었다. 이러한 분포 경향은 하천을 통해 광양만으로 DBP와 DEHP가 유입되고 있음을 시사한다.
