摘要：
Sao Paulo, a megacity in South America, is the largest consumer of fossil fuels in Brazil. The petrochemical products play an important role in the Brazilian economy and in the energy matrix. The compounds emitted when oil is used or processed can affect air quality and endanger human health. Particulate matter and gaseous samples were collected simultaneously in 2015 at an urban site highly impacted by anthropogenic activities, in the city of Santo Andre, Sao Paulo Metropolitan Area. Samples were analysed for elemental and organic carbon, hopanes, n-alkanes, alkenes polycyclic aromatic hydrocarbons and their oxygenated and nitrated derivatives. Among the polycyclic aromatic hydrocarbon, phenanthrene presented the highest concentration in PUF and benzo(b)fluoranthene was dominant in PM. The carcinogenic equivalents for benzo(a)pyrene were 2.1 for PAH and 1.2 for nitro-PAH. The results showed that local activities as vehicular and industrial activities affected the air quality.
