ResumoCoarse particulate matter (PM 10 ) concentrations and chemical composition were monitored from 2014 to 2017 at three sampling sites in the Metropolitan Region of Rio de Janeiro, namely Botafogo, Gávea, and Gericinó.All sites are located close to the 2016 Olympic Game arenas.The average annual PM 10 concentrations were above the limits recommended by the World Health Organization (WHO) at all sampling sites.Of all the analyzed water-soluble ions, the highest concentrations were obtained for NO 3 -, SO 4 2-, Cl -and Na + .Sulfate displayed a higher anthropic contribution (ca.70%).Iron and copper were present in all samples, originated from soil resuspension and traffic (fuels and brakes, among others).Overall, civil works to restructure the city and the construction of the Olympic Game arenas increased PM 10 and some of its constituent levels prior to 2016.After the Olympic Games, PM 10 concentrations have decreased, due to governmental policies regarding traffic planning and civil work finalization.
