TL;DR: In the present study, 2-NBA, 3-NBA and selected PAHs and Nitro-PAHs were determined in fine particle samples collected in a bus station and an outdoor site, showing low cancer risk incidence and incremental lifetime cancer risk (ILCR) calculated for both places.

TL;DR: However, there are major drawbacks in the use of biofuel blends as NOx tends to be higher, the intervals of motor parts replacement such as fuel filters are reduced and degradation by chronic exposure of varnish deposits in fuel tanks and fuel lines, paint, concrete, and paving occurs as some materials are incompatible as mentioned in this paper.

TL;DR: In this paper, a comparison was carried out between the two most widely used CC collection methods: C18 cartridges coated with an acid solution of 2,4dinitrophenylhydrazine (2,4-DNPH) and impinger bottles filled in 2, 4DNPH solution.

TL;DR: In this paper, the atmospheric concentrations of TSP, PM10 and elements such as iron, manganese, copper and zinc, from three different sites around Salvador Region (Bahia, Brazil), namely: (i) Lapa Bus Station, strongly impacted by heavy-duty diesel vehicles; (ii) Aratu harbor, impacted by an intense movement of goods, including metal ores and concentrates and near industrial centers and; (iii) Bananeira Village located on Mare Island, a non-vehicle-influenced site, with activities such as handcraft work

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.
