Air Pollutants And Respiratory Symptoms Among Adults, Paulo A. Lotufo

Paulo A Lotufo

Air pollutants are associated with adverse respiratory effects mainly in susceptible groups such as children, elderly people and people with pre-existent respiratory disease. This study was designed to assess the impact of the inorganic composition of particulate matter on 33 adult asthmatics respiratory functions in São Paulo city, Brazil. From May to July 2002, fine and coarse particulate matter fractions were collected and trace metals (Fe2+, Mn2+, Zn2+, Pb2+, Cu2+) and major ions (Na+, Mg2+, K+, Ca2+, NH4 +, Cl-, NO3-, SO42-) composition was determined in each aqueous-extract fraction by Atomic Absorption Spectrometry with Graphite Furnace (AAS-GF) and Ion Chromatography, …

The Polycyclic aromatic hydrocarbons PAHs (naphthalene, acenaphthylene, acenaphthene, phenanthrene, fluoranthene, pyrene, benzo(a)anthracene, chrysene, benzo(b)fluoranthene, benzo(k)fluoranthene, benzo(a)pyrene, indeno(1,2,3-cd)pyrene and benzo(ghi)perylene) concentrations in fine (PM2.5) and coarse (PM2.5–10) atmospheric particulate matter were measured at Sa˜o Paulo city, Brazil. The dominant PAHcompounds were indeno(1,2,3-cd)pyrene, benzo(ghi)perylene and benzo(b)fluoranthene for both the fractions. The calculated ratios of some specific PAHs were in close agreement with those attributed to direct emissions of car exhaust. The factor analysis for PM2.5 produced four factors: Factor 1 was attributed to diesel emissions, Factor 2 was attributed to stationary combustion source, Factor 3 was attributed to vehicular emissions and Factor …
