Abstract
ARGUMEDO, Carlos Doria and CASTILLO, Juan Fagundo. Chemical characterization of particulated atmospheric matter PM10 in Guajira, Colombia. Rev.Colomb.Quim. [online]. 2016, vol.45, n.2, pp.19-29. ISSN 0120-2804. https://doi.org/10.15446/rev.colomb.quim.v45n2.56991.
During 2013, a study in La Guajira, Colombia, was conducted to characterize both aqueous and respirable fractions of particulate matter PM10, result of coal mining activities that occupy nearly 30% ofthe territory, and to evaluate its association with natural and anthropogenic sources. Filters collection was carried out through a monitoring system that consists in fourteen stations, using a high volume sampling equipment PM10 (Thermo Scientific VFC-PM10 High Volume Air Sampler). The extraction was done with hot water and the analysis by UV-VIS spectrophotometry. The highest concentrations correspond to SO42- (0.25 μg/ m3), Cl- (0.19 μg/m3), NH4+ (0.032 μg/m3), Na+ (1.98 μg/m3), Ca2+ (0.40 μg/m3) and Mg2+ (0.31 μg/m3). Results indicate that the main responsible sources of t e c emical content in particulate matter correspond to marine aerosol, impulsed by sea currents (Cl-and Na+) from natural origin, and agricultural activities, livestock (NH4+) and mining (SO42-, Ca2+ and Mg2+) from anthropo genic origin.
