Abstract

PFOS (Perfluorooctane sulfonate) and PFOA (Perfluorooctanoic acid) are environmental hormones which belong to potential future persistent organic pollutants (POPs), and it is easy to exposure to human because they are used in a wide variety of consumer products. We studied exposure route and the relativity through determining and monitoring of PFOS and PFOA in Korean plasma of metropolis, small town, rural area and industrial area. And we monitored the concentration of PFOS and PFOA regarding the gender and age. The older age is, the higher concentration of PFOS is. The mean concentration of PFOS and PFOA in men (4.74 ng/mL, 2.20 ng/mL) was higher than that in women (3.53 ng/mL, 1.17 ng/mL). In the comparison of residential areas, the mean concentration of PFOS and PFOA was the lowest in metropolitan plasma (2.47 ng/mL, 0.79 ng/mL) whereas it was the highest in the industrial area (6.57 ng/mL, 2.19 ng/mL).

PFOS (Perfluorooctane sulfonate)와 PFOA (Perfluorooctanoic acid)는 POPs 물질로 환경호르몬 중의 하나이다. 이 물질들은 포장재, 일회용품 등 널리 사용되어지고 있는 소비상품에 함유되어 있기 때문에 사람에게 쉽게 노출될 수 있다. 본 연구에서는 노출경로에 대해 연구하기 위해 대도시, 중소도시 및 시골의 주거지역과 산업지역에서의 PFOS, PFOA에 대한 인체 혈장 중에 함유된 수준을 조사하였으며, 성별과 연령별도 조사하였다. 고령일수록 PFOS의 농도는 높아졌으며, PFOS와 PFOA의 평균농도는 남자(4.74 ng/mL, 2.20 ng/mL)가 여자 (3.53 ng/mL, 1.17 ng/mL)보다 높게 조사되었다. 거주지역을 비교해보면, PFOS와 PFOA의 평균농도는 대도시 거주자(2.47 ng/mL, 0.79 ng/mL) 의 경우 가장 낮았으며, 산업지역 거주자(6.57 ng/mL, 2.19 ng/mL)의 경우가 가장 높게 조사되었다.
