Abstract

U ukupnom atmosferskom taloženju istraživani su slijedeći elementi: Al, Fe, As, Cr, Co, Sr, Se, Cu, Mn, Mo, V, Zn, Pb, Cd, Ni, Sb, Sn, Ti, Ba i Rb. Dnevni uzorci oborina sakupljani su u periodu od travnja 2009. do svibnja 2010., u središtu Zagreba. Koncentracije metala mjerene su ICP-MS tehnikom, u originalnim i filtriranim uzorcima. Taloženje metala u istraživanom periodu bilo je znatno manje, izuzev za Cr, nego u drugim urbanim sredinama prema podacima iz literature. Visoki udio u otopljenoj frakciji (>70%) uočena je kod Sr, Zn, Cd, Ni, Cr i As. Faktor obogaćenja (enrichment factor, EF) bio je veći od 500 samo za Cd, što jasno ukazuje na njegovo antropogeno porijeklo.

Abstract (english)

The bulk atmospheric deposition of the minor and trace elements (Al, Fe, As, Cr, Co, Sr, Se, Cu, Mn, Mo, V, Zn, Pb, Cd, Ni, Sb, Sn, Ti, Ba i Rb) was investigated. The daily samples were collected in the period from April, 2009 until May, 2010 in the centre of Zagreb. Concentrations of metals were measured by HR ICP-MS in unfiltered and filtered samples. With the exception of Cr, deposition fluxes of the metals in the period of investigation were lower than those reported in the literature for other urban sites. The high percentage of dissoluted fraction ( > 70%) was found for Sr, Zn, Cd, Ni, Cr and As. The enrichment factor of Cd was higher than 500, indicating a clear anthropogenic origin.
