Implication

Meta-analysis reveals increased lung cancer risk from cumulative benzo[a]pyrene exposure in occupational cohorts, highlighting industry-specific risk variations for hazard assessment.

Key Points

To clarify and quantify the occupational exposure-response relationship between polycyclic aromatic hydrocarbon mixtures and lung cancer risk.
Conducted a systematic review and meta-analysis of 39 published occupational epidemiologic cohort studies.
Calculated unit relative risks (URRs) standardized to 100 μg/m³-years of benzo[a]pyrene across various occupational sectors and evaluated potential confounders including smoking and total dust.
The average estimated unit relative risk (URR) at 100 μg/m³-years benzo[a]pyrene was 1.20 (95% CI, 1.11–1.29) and remained stable across differing analytical methods.
Mean URRs were comparable in coke ovens, gasworks, and aluminum production (1.15–1.17), but were significantly higher for asphalt workers (URR = 17.5; 95% CI, 4.21–72.78) and chimney sweeps (URR = 16.2; 95% CI, 1.64–160.7).
Relative risk estimates did not vary significantly within industries, by study design, by smoking adjustment, or by the presence of total dust co-exposure.
