Abstract	Human dermal exposure to chlorinated paraffins (CPs) has not been well documented. Therefore, hand wipes were collected from four occupational populations to analyze short-chain CPs (SCCPs) and medium-chain CPs (MCCPs) in order to estimate dermal uptake and oral ingestion via hand-to-mouth contact. The total CP levels (& sum;SCCPs and & sum;MCCPs) in wipes ranged from 71.4 to 2310 mu g/m(2) in security guards, 37.6 to 333 mu g/m(2) in taxi drivers, 20.8 to 559 mu g/m(2) in office workers, and 20.9 to 932 mu g/m(2) in undergraduates, respectively. Security guards exhibited the highest levels of & sum;SCCPs among four populations (p < 0.01). In undergraduates engaged in outdoor activities, C-13 emerged as the most dominant SCCPs homologue group, followed by C-12, C-11, and C-10. The levels of & sum;SCCPs and & sum;MCCPs in males in light haze pollution were significantly higher than that in heavy haze pollution (p < 0.05). The median estimated dermal absorption dose of SCCPs and MCCPs via hand was 22.2 and 104 ng (kg of bw)(-1) day(-1), respectively, approximately 1.5 times the oral ingestion [12.3 and 74.4 ng (kg of bw)(-1) day(-1)], suggesting that hand contact is a significant exposure source to humans.
