Exposure Assessment of Polycyclic Aromatic Hydrocarbons Using Urine 1-OHP Metabolites of Housewives

Polycyclic aromatic hydrocarbons (PAHs) are well known for strong carcinogen. However, the human exposure analysis of PAHs is quite difficult and unreliable because of hard for estimation of actual expose dose. Then urinary 1-hydroxypyrene (1-OHP) has been a biological marker of exposure to PAHs. The purpose of this study was to investigate total amount from exposure to PAHs caused by indoor environment of residents who are non-smokers, could not expect occupational expose, and residence at Seoul metropolitan area and Kyeonggi province in Korea.
