TAMES, María Florencia; TAVERA BUSSO, Iván y CARRERAS, Hebe Alejandra. OPTIMIZED METHOD FOR PARTICULATE MATTER-ASSOCIATED POLYCYCLIC AROMATIC HYDROCARBONS DETERMINATION. Rev. Int. Contam. Ambient [online]. 2019, vol.35, n.2, pp.387-395. Epub 19-Feb-2020. ISSN 0188-4999. https://doi.org/10.20937/rica.2019.35.02.10.
Polycyclic aromatic hydrocarbons are ubiquitous air pollutants, derived from the incomplete combustion of organic matter. Due to its physical and chemical characteristics, its association with the particulate matter is favored, and therefore its permanence in the atmosphere. In recent decades, the monitoring of polycyclic aromatic hydrocarbons in urban atmospheres has become a priority due to the high number of exposed individuals. In the present work, modifications of a standard methodology for the extraction, detection and quantification of polycyclic aromatic hydrocarbons were evaluated. These modifications resulted in reductions both in the extraction and quantification time, as well as in processing costs, which implies a substantial improvement in sample processing time, without reducing the sensitivity. In addition, the considerable reduction in the amount of solvent employed resulted in an environmentally friendly methodology.
