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).
