The burning of fossil fuels and industrial activities are mainly responsible for the emission of air pollutants. These pollutants are increasingly associated with negative effects on human health. This work aimed to assess air quality in São Gonçalo do Amarante city, State of Ceará, which owns 46.8% of its territory in the area of the Pecém Industrial Complex (CIP). Experimentally, samples were carried out between october and december 2015 for the parameters: total suspended particulate (TSP), NO2, SO2, O3 and heavy metals (Fe, Ni, Cu and Pb) using large volume samplers (64 m /h) for TSP and small volume (0.20 L/min) for SO2 and NO2. The ozone was determined by absorption in the ultraviolet (254 nm) and the concentrations of heavy metals associated with TSP were estimated by atomic absorption spectroscopy. The results showed TSP levels (24 h) between 32.6 and 75.3 μg/m and ozone (1 h) between 63.8 and 165.6 μg/m. The concentrations of SO2 and NO2, in turn, were lower than the values established by Brazilian legislation. Among metals, only iron was quantitatively identified, with levels between 3.6 and 19.9 μg/m. In general, the values obtained showed that the air quality in the area during the study period can be considered as good for the environmental pollutants analyzed.
