Abstract

Air quality and precipitation chemistry (wet deposition) of Metropolitan Area of Sao Paulo (MASP) and Cubatão, one characterized by a large vehicle fleet (Sao Paulo), and the other for the large industrial complexes (Cubatão). Concentrations of sodium, chloride, nitrate, calcium, and sulfate ions were higher in Cubatão than at MASP. In Cubatão, topography, and lower wind speeds associated with the sea-breeze circulation hinder the dispersion of air pollutants. Both sampling sites had higher levels during winter and autumn due to absence of frequent rainfall events. Vila Parisi, which is located in close vicinity to large petrochemical plants, a similar pattern was visible for the percentile wind-rose of Cubatão-Center, which is further away from emissions sources. The 99th percentile SO2 concentrations in MASP (Congonhas) were one-fourth of levels at Vila Parisi's, indicating that Cubatão concentrations are still a matter of concern and could result in severe air pollution episodes. This is an abstract of a paper presented at the AWMA's 107th Annual Conference & Exhibition (Long Beach, CA 6/24-27/2014).
