Simultaneous evaluation of polycyclic aromatic hydrocarbons and carbonyl compounds in the atmosphere of Niterói City, RJ, Brazil

Atmospheric particulate matter (total suspended particulate – TSP – and inhalable particles – PM10) and gas-phase samples were collected in three periods of seven to nine consecutive days in June and December 2011, and May 2012, in the central area of Niteroi City, Rio de Janeiro State, Brazil. TSP (48.8–214 μg m−3) showed higher concentrations than PM10 (nd – 82.6 μg m−3). Sixteen polycyclic aromatic hydrocarbons (PAH) and thirty-one carbonyl compounds (CC) were evaluated. Concentrations of individual PAH ranged from
