“…In Rio de Janeiro city, heavy metal concentrations were determined in particulate matter emitted from urban and industrial sources of pollution [23][24][25][26][27][28][29][30][31][32][33][34]. In only one work, operational speciation was applied for heavy metal fractionation to identify emission sources [27].…”

“…However, SC is considered an urban settlement without natural barriers, the predominant wind coming from the east, and with a vector wind in the dry-cold season from the southeast that is in uenced by the emissions generated in Toluca downtown. It is possible that additional emissions, mainly produced by industrial plants located in the south and south-east AP and SM sites, as well as by the resuspension of road dust and biomass combustion (Quiterio et al, 2005;Mansha et al, 2012) contribute to local pollution.…”

The Toluca Valley Metropolitan Area (TVMA) is the fth largest urban center in Mexico, located at high altitude, 2660 meters above sea level (m.a.s.l.) surrounded by mountain ranges. It is composed of heterogenous residential and industrial areas with dense vehicular tra c. This combination of geography and urbanization create a metropolitan area with high levels of air pollutants. The objective of this study was to provide evidence of the seasonal and spatial variation of metal(lloid)s in particulate matter minor to 2.5 microns (PM 2.5) in Toluca Valley. Four sites were sampled between 2013-2014, that include urban and industrial areas, in the dry-cold (November-February) and hot-dry (March-May) season; PM 2.5 were collected using high and medium volume samplers. Metal and metalloids concentrations in PM 2.5 were analyzed using Inductively Coupled Plasma Mass Spectrometry (ICP-MS). Our results show the highest 24-hour PM 2.5 concentration in the northern area, followed by the southern industrial area, and the lowest concentrations was observed in the southwest area independent of the season. Metals and metalloids with a recovery percentage above 80% were Cobalt (Co), Chrome (Cr), Copper (Cu), Manganese (Mn), and Antimony (Sb). The maximum concentrations of them were observed during the dry-cold season, in the urban-industrial sites found in the north and southern areas. Co, Cr, Cu, Mn, and Sb concentrations were up to one hundred or thousand folded in the dry-cold season compared to dry-hot season due to weather and geographical features of TVMA. The 24-hour PM 2.5 and metal(lloid)s concentrations exceed national and international guidelines to protect population health.
