Title: Polycyclic aromatic hydrocarbons: levels and phase distributions in preschool microenvironment
Issue Date: 2015-10-01
Abstract: This work aims to characterize levels and phase distribution of polycyclic aromatic hydrocarbons (PAHs) in indoor air of preschool environment and to assess the impact of outdoor PAH emissions to indoor environment. Gaseous and particulate (PM1 and PM2.5) PAHs (16 USEPA priority pollutants, plus dibenzo[a,l]pyrene, and benzo[j]fluoranthene) were concurrently sampled indoors and outdoors in one urban preschool located in north of Portugal for 35 days. The total concentration of 18 PAHs (Sigma PAHs) in indoor air ranged from 19.5 to 82.0 ng/m(3); gaseous compounds (range of 14.1-66.1 ng/m(3)) accounted for 85% Sigma PAHs. Particulate PAHs (range 0.7-15.9 ng/m(3)) were predominantly associated with PM1 (76% particulate Sigma PAHs) with 5-ring PAHs being the most abundant. Mean indoor/outdoor ratios (I/O) of individual PAHs indicated that outdoor emissions significantly contributed to PAH indoors; emissions from motor vehicles and fuel burning were the major sources.
