In this work, the quantification and chemical characterization of particulate matter (PM) was carried out, focusing on coarse particulate matter (PM10) collected in four different locations in the metropolitan region of Rio de Janeiro (Gericinó, West Zone; Duque de Caxias, Baixada Fluminense; Bonsucesso, North Zone and Center-central region of the city), employing large volume samplers and fiberglass filters, supplied by the State Institute of the Environment (INEA). Using filters throughout 2019, analyzes were carried out in Ion Chromatograph (IC) and inductively coupled plasma mass spectrometry (ICP-MS) for the characterization of the samples and quantification of ions and metals. An evaluation of PM10 concentration under the precipitation influence was also carried out over 10 years of study (2010 to 2019) and the levels compared with the values recommended by CONAMA. To complete the study, a bibliographic study on vehicular pollution related to PM10 in Brazil was implemented. The results point to an increase in PM10 levels over the evaluated decade, mainly in the Bonsucesso region, with average concentrations of 62 (micro)g m-3 , in some cases overreaching the limits of CONAMA. Concerning the precipitation, there was a statistically significant discrepancy in days with rain and days without rain. The ions that showed the highest concentrations were NO3 - , SO4 2- and Na+ with mean concentrations ranging from 2.6-3.4; 3.0-3.3; 2.4-3.0 (micro)g m-3 , respectively, in all groups of the study. The metal analysis defined Fe and Cu as the most represented metals in the samples, with mean concentrations ranging from 0.54 to 0.73 and from 0.023 to 0.047 (micro)g m3 , respectively. Such results are strengthened by the analysis of Black carbon through optical absorption, which reported an average concentration ranging from 3.6 to 6.0 (micro)g m-3 . The Bonsucesso region showed to be the one with the highest concentrations for the aforementioned parameters, confirming the influence of the greater vehicular traffic reported for the region.
