ISOTOPE COMPOSITION AND HOST PHASES OF LEAD IN AIRBORNE PARTICULATE MATTER FROM BUDAPEST, HUNGARY

摘要

Lead is a frequent potentially toxic pollutant of the urban environment. Its complete risk assessment in the airborne particulate matter requires data both on its speciation and potential sources. In this paper we present results on detailed mineralogical (XRD and TEM) and geochemical (selective chemical extractions and lead isotope ratio analyses) study of total suspended particulate (TSP) matter samples from Budapest, Hungary to fulfil this requirements.
