Human Exposure Levels of Volatile Organic Compounds in E-waste Recycling Area: Get Insight into Impacts of Manipulation Mode and Associations with Oxidative Stress Markers.

ABSTRACT: There is currently a dearth of evidence regarding the impact of the manipulation mode on human occupational exposure to volatile organic compounds (VOCs) originating from e-waste dismantling. Therefore, 11 VOC metabolites (mVOCs) and four oxidative stress biomarkers (OSBs; i.e., 8-oxo-7,8-dihydro-2'-deoxyguanosine, 8-oxo-7,8-dihydro-guanosine, 8-oxo-7,8-dihydroguanine, and dityrosine) were analyzed in urine collected from two disassembly regions. Urinary ∑mVOC concentrations were significantly higher for e-waste-related participants than controls (geometric mean: 2500 vs 1360 ng/mL; p < 0.05). Notably, adults from formal dismantling site (3020 ng/mL) had equivalent ∑mVOC levels as those from informal area (2830 ng/mL) but with varying composition features, indicating that elevated e
