Abstract
Determination were performed for the presence of three common environmental endocrine disrupting compounds (EDC), namely nonylphenol (NP), octylphenol (OP), di (2-ethylhexyl)phthalate in sewage sludge from 67 wastes plants, using Soxhlet extraction and GC/MS-SIM. NP and DEHP were detected in almost every sludges but OP was not detected. The range and mean value for NP of all sludge samples were nd~593, <TEX>$62{\mu}g/g$</TEX> dry and the two statistic values for DEHP of those were 13~4733, <TEX>$1176{\mu}g/g$</TEX> dry respectively. DEHP content was 20 times greater than NP in sludges. Concentrations of NP and DEHP in sludge from individual area were increased as following order ; Jeolla South and North Province (Cheju) < Chungcheong South and North Province (Kwangwon) < Gyungsang South and North Province < Wide City < Kyunggi Province.
