Exposure to polycyclic aromatic hydrocarbons (PAHs), particularly when bound fine particulate matter (PM2.5), is an emerging concern for adverse prenatal health outcomes. This study investigates the associations between exposure PAHs-bound PM2.5 and markers of inflammation oxidative stress in umbilical cord blood. We conducted a prospective 450 mother-infant pairs, assessing levels during pregnancy using personal air sampling. Inflammatory biomarkers, including TNF-α, IL-6, IL-8, TGF-β, Pro-oxidant Antioxidant Balance (PAB), were measured Multivariable linear regression was used examine individual PAHs these while mixture effects evaluated quantile g-computation Bayesian Kernel Machine Regression (BKMR) assess combined influence 15 PAH congeners. Our findings revealed significant specific increased PAB. Mixture analysis indicated that each one-quartile increase associated with 0.31 pg/mL (95 % CI: 0.05-0.60, p = 0.01), 1.26 0.43-2.08, < 26.02 2.98-49.07, 0.02) respectively. However, IL-6 PAB showed no associations. BKMR further confirmed dose-response relationship elevated inflammatory markers. These highlight potential risks PM2.5, emphasizing need research mitigate developmental effects.
