TL;DR: In this article, a year-round sampling was performed at the University of Sao Paulo campus (20m) in Brazil to evaluate the sources of particulate air pollution and related health risks, and different chemical constituents, such as carbonaceous species, polycyclic aromatic hydrocarbons (PAHs), water-soluble ions, and biomass burning tracers were identified in order to evaluate health risks and to apportion sources.

TL;DR: The participation of XPC protein, and NER pathway, in the protection of mice against the carcinogenic potential of air pollution is demonstrated, demonstrating that DNA is damaged directly (forming adducts) or indirectly (Reactive Oxygen Species) by the various compounds detected in urban PM2.5.
Journal ArticleDOI

TL;DR: The concentration of 15 PAHs in soil and sediments at different sites from the Awotan-Asunle dumpsite area in the Southwestern region of Nigeria, which is one of the largest dumpsites in Africa was determined by GC-MS.
Journal ArticleDOI

TL;DR: The source attribution in Medellín, Bogotá, Buenos Aires, and Lima confirmed the mixed contributions of biological material, secondary formation, as well as urban and biomass burning emissions.
Journal ArticleDOI

TL;DR: In this paper, the concentrations of particulate matter, organic carbon (OC), elemental carbon (EC), biomass burning tracers (levoglucosan, mannosan, and galactosan), water-soluble ions, and polycyclic aromatic hydrocarbons (PAHs) were determined to identify the main sources affecting the air quality.
