title: Occupational exposure to polycyclic aromatic hydrocarbons: A cross-sectional study in bars and restaurants in Santiago, Chile.
abstract: To evaluate indoor polycyclic aromatic hydrocarbon (PAH) concentrations in bars and restaurants and identify the main determinants of airborne PAH concentrations.
  
  
  
  This study included 57 bars/restaurants in Santiago, Chile. PAH concentrations (ng/m(3) ) were measured using photoelectric aerosol sensor equipment (PAS 2000CE model). Nicotine concentrations (μg/m(3) ) were measured using active sampling pumps followed by gas-chromatography. Linear regression models were used to identify determinants of PAH concentrations.
  
  
  
  PAH concentrations were higher in venues that allowed smoking compared to smoke-free venues. After adjusting, the air PAH concentrations were 1.40 (0.64-3.10) and 3.34 (1.43-7.83) ng/m(3) higher for tertiles 2 and 3 of air nicotine compared to the lowest tertile.
  
  
  
  In hospitality venues where smoking is allowed, secondhand smoke exposure is a major source of PAHs in the environment. This research further supports the importance of implementing complete smoking bans to protect service industry workers from PAH exposure. Am. J. Ind.
