초록

빗물, 증류수, 정수기 물, 지하수, 수돗물, 시판생수에 포함된 주요 환경호르몬 물질로 알려진 nonylphenol(NP), octylphenol(OP), di(2-ethylhexyl)phthalate(DEHP)를 OASIS 카트리지로 추출한 후 GC/MS를 이용하여 정량하였다. Octylphenol 은 어느 물 시료에서도 검출되지 않았으나, nonylphenol 의 경우는 그 존재량이 빗물<정수기 물<증류수<지하수<수돗물<시판생수의 순으로 증가하였으며, 시판생수의 경우 최고 <TEX>$0.44{\mu}g/L$</TEX>(ppb)가 포함되어 있었다. Di(2-ethylhexyl)phthalate는 모든 물 시료에 포함되어 있었으며 빗물의 경우 <TEX>$1.7{\sim}2.9{\mu}g/L$</TEX>, 증류수는 <TEX>$8.7{\sim}31.7{\mu}g/L$</TEX>, 정수기 물은 <TEX>$0.6{\sim}5.6{\mu}g/L$</TEX>(평균: <TEX>$2.5{\pm}0.3{\mu}g/L$</TEX>)로 다른 값에 비하여 매우 안정한 값을 나타냈고, 전주근교 지하수는 <TEX>$1.1{\sim}6.0{\mu}g/L$</TEX>, 수돗물은 평균 <TEX>$3.1{\sim}5.7{\mu}g/L$</TEX>, 시판생수는 <TEX>$0.5{\sim}67.6{\mu}g/L$</TEX> 이였으며 시중의 시판 생수 중 40% 이상이 USEPA기준을 초과하고 있었다.

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%.
