Salivary 8-hydroxy-2'-deoxyguanosine as a biomarker of oxidative DNA damage in urban outdoor workers exposed to traffic-related air pollution.
Urban air pollution, particularly fine particulate matter (PM2.5), is a major environmental health concern associated with oxidative DNA damage. However, evidence in occupationally exposed and socially vulnerable populations remains limited, and applicability of noninvasive biomarkers requires further investigation. Th...
