Abstract
The most common 8 phthalic acid esters (PAEs) and adipate in sediment were measured 5 times from 1999 to 2001 at 11 sites of river in Korea. Ultrasonication extraction with dichloromethane was done for extraction of the sediment. After concentration GC/MS-SIM analysis was performed. Three compounds (DEP, DBP and DEHP) among eight phthalic acid esters were detected from the sediment samples, and the other PAEs were not detected in any samples. DEHP (27.3~63.6%) was detected with higher frequency than any other compounds for sediment samples. And this compound had shown the highest average concentration (81.7~427.6 ng/g).
