“…In the class below one μm, mostly secondary aerosols composed of sulphates, nitrates, ammonium ions, and Ca [18], therefore the metal content is minimal. Fe accounts for up to 87% of the total amount of monitored trace elements [19]. Trace elements usually represent only 5% of the total amount in PM10.…”

The Moravian-Silesian Region is one of the most polluted sites by dust particles in the Czech Republic. Therefore, atmospheric concentrations of heavy metals as cadmium, cobalt, chromium, copper, nickel, lead, antimony, thallium, manganese, iron and zinc, were monitored at 10 localities in the region during summer of 2014. Heavy metals were monitored in 10 particle size classes from 18.3 nm to 9.93 µm. The percentage of the amount of heavy metals in the sum PM at all localities ranged from 0.2-2.5%. It was found that chromium, manganese, iron and zinc were mostly accumulated in dust particles with diameter greater than 1.6 µm. Lead, cadmium and antimony occur mainly in the class below 0.949 µm. These metals are more dangerous for human health, and can have potential carcinogenic effect. The influence of metallurgical industry evaluated on the basis of heavy metals in the individual particle size classes in the air within the Moravian-Silesian Region has not been unequivocally demonstrated.

“…Long-term data on PM 2.5 levels and time trends of PM 2.5 constituents are therefore available only for some European countries such as Greece (Mantas et al, 2014), Spain (Querol et al, 2014) and The Netherlands (Mooibroek et al, 2011). Systematic monitoring of PM 10 mass concentration and composition determination are the most frequent in literature for Hungarian urban environment (Muránszky et al, 2011). Major pollution sources encompass vehicular traffic, residential heating and household activities in Budapest.…”

“…Por ejemplo, algunos elementos traza presentes en PM10 y PST estas clasificados como cancerígenos para los humanos tales como el V, Pb y Cd (MAVDT, 2010). Investigaciones realizadas han mostrado sus efectos cancerígenos y alérgicos cuando se estudian en partículas PM10 (Muránszky et al, 2011;Ravindra et al, 2004).…”

ResumenEn esta investigación se evaluó la concentración, composición elemental y fuentes de origen de partículas PM10 y PST. Quince elementos químicos (As, Cd, Ca, Zn, Cu, Cr, Co, Fe, Mg, Mn, Ni, Pb, K, Na y V) se determinaron utilizando espectrometría de absorción atómica. Los niveles de PM10 (19.4 y 51 µg/m 3 ) y PST (27.6 y 53.7 µg/m 3 ) no excedieron estándares internacionales. El Factor de Enriquecimiento (FE) mostró que los elementos de trazadores de suelo están asociados con las partículas PST, mientras que los elementos de origen antropogénicos están asociados con las partículas PM10. El Zn, Cu y Co, mostraron fuerte enriquecimiento en PM10 y PST en las dos estaciones, concluyéndose que son elementos de origen antropogénicos. Para el grupo de trazadores de suelo: Na, As, Pb y Ni, presentaron enriquecimiento moderado. Los resultados mostraron que el Mg, Mn, V y K se originan en el proceso natural del suelo. Palabras clave: PM10, PST, fuentes de contaminacion, traza de elemento, factor de enriquecimiento Elemental Composition and Sources of Inhalable Particles (PM10) and Suspended Total Particles (TSP) in the Urban Area of the City of Riohacha, Colombia AbstractThis research evaluated the concentration, elemental composition and sources of origin of particle PM10 and TSP. Fifteen chemical elements (As, Cd, Ca, Zn, Cu, Cr, Co, Fe, Mg, Mn, Ni, Pb, K, Na and V) were determined using atomic absorption spectrometry. Levels of PM10 (19.4 and 51 µg/m3) and TSP (27.6 and 53.7 µg/m3) did not exceed international standards. The enrichment factor (EF) showed that the soil tracer elements are associated with TSP particles while elements of anthropogenic origin are associated with PM10 particles. Zn, Cu and Co, showed strong enrichment in PM10 and TSP in the two stations, concluding that are elements of anthropogenic origin. For the group of soil trace elements: Na, As, Pb and Ni, showed a moderate enrichment. The results showed that elements such as Mg, Mn, V and K originated from the natural process of soil.
