In this study, we aimed to assess PAH exposure by measuring the hydroxylated metabolites (hydroxy-PAHs) in urine samples of a rural population from the North China Plain and to explore the possible associations between PAH exposure and oxidative stress indicated by urinary malondialdehyde (MDA) and 8-hydroxy-2'-deoxyguanosine (8-OHdG). High levels of urinary hydroxy-PAHs were observed, with the geometric mean concentrations of 0.57, 2.2, 5.0, 7.0, and 16.6 mu g g(-1) creatinine for 1-hydroxypyrene, hydroxyphenanthrenes, hydroxyfluorenes, hydroxybiphenyls, and hydroxynaphthalenes, respectively. Particularly in the winter season, the exposures were 2.3-6.0-fold of those in the spring. Corresponding to PAH exposure, levels of urinary MDA were positively associated with hydroxy-PAHs after controlling for confounders in the linear regression models (p &amp;lt; 0.05). An estimation indicated 21.3-39.3 % increment of urinary MDA per one-fold increase of hydroxy-PAHs. In contrast, no significant correlation was found between urinary 8-OHdG and hydroxy-PAHs; alternatively, living at the e-waste recycling site was found a significant factor on this oxidative DNA damage. These results provide evidence on high PAH exposure and the induction of oxidative stress on lipid peroxidation for this rural population.</style></abstract><accession-num><style face="normal" font="default" size="100%">WOS:000348917400026</style></accession-num><notes><style face="normal" font="default" size="100%">&lt;p&gt;Times Cited: 111st International Conference on Environmental Specimen BankOct, 2013Shanghai, PEOPLES R CHINAState Key Lab Pollut Control &amp;amp; Resource Reuse; Minist Educ, Key Lab Yangtze River Water Environm122351614-7499&lt;/p&gt;</style></notes></record></records></xml>
