An intensive sampling campaign was conducted in a Mexican small town in order to characterize the toxic species emitted by more than 400 adobe kilns working in two scenarios: low and normal activity, as well as to determine their carcinogenic potential. PM10 concentrations ranged 50-80 μg m−3 and 77-290 μg m−3 during low and normal activity periods, while PM2.5 concentrations were 33-57 μg m−3 and 37-177 μg m−3in the same periods. Organic carbon and elemental carbon presented concentrations around four and seven times greater, respectively, during a normal activity period than during a low activity period in both particle sizes. Quantified polycyclic aromatic hydrocarbons were twice greater during the normal activity period than during the low activity period. Carcinogenic PAHs accounted for 53-59% of total PAHs in all cases and the carcinogenic potential (B[a]Peq) in PM10 during the normal activity was 25 times higher than the European Commission recommendation, proving thereby the high risk that nearby population faces to those emissions. 2021 artículo científico 0187-6236 https://www.redalyc.org/articulo.oa?id=56572283002 https://www.redalyc.org/journal/565/56572283002/ https://www.redalyc.org/journal/565/56572283002/html/ https://www.redalyc.org/journal/565/56572283002/56572283002.epub https://www.redalyc.org/journal/565/56572283002/movil 10.20937/ATM.52756 en http://www.redalyc.org/revista.oa?id=565 Atmósfera application/pdf Universidad Nacional Autónoma de México Atmósfera (México) Num.1 Vol.34 |
