Abstract
Determination were performed for the presence of three common environmental endocrine disrupting compounds (EDC), namely nonylphenol (NP), octylphenol (OP), di(2-ethylhexyl)phthalate (DEHP) in rainwater, distilled water, millipore water, groundwater, tap water, and bottle water in market, using OASIS cartrige extraction and GC/MS-SIM. Octylphenol was not detected in any water samples. The order of nonylphenol concentrations were increased in rainwater < millipore water < distilled water < groundwater < tap water < bottle water. The concentration of nonylphenol in bolltle water was <TEX>$0.44{\mu}g/L$</TEX>(ppb) at highest. Di(2-ethylhexyl)phthalates were detected in every water samples, and the concentrations were to be <TEX>$1.70{\sim}2.92{\mu}g/L$</TEX> in rainwater, <TEX>$8.7{\sim}31.7{\mu}g/L$</TEX> in distilled water, <TEX>$0.6{\sim}5.6{\mu}g/L$</TEX>(mean: <TEX>$2.5{\pm}0.3{\mu}g/L$</TEX>) in millipore water, and that were very stable values than other waters, <TEX>$1.1{\sim}6.0{\mu}g/L$</TEX> in groundwater at near Jeonju, <TEX>$3.1{\sim}5.8{\mu}g/L$</TEX> by means in tap water, <TEX>$0.5{\sim}67.6{\mu}g/L$</TEX> in bottle water from market. The concentration of DEHP in bottle water samples from market were in higher than USEPA regulation at over 40%.
