A Sequential Extraction Method for the Chemical Speciation of Metals in Harmattan Dust Collected from Kano and Zaria Cities in Northern Nigeria
Journal Title: International Journal of Research in Chemistry and Environment (IJRCE) - Year 2012, Vol 2, Issue 2
Abstract
Harmattan dusts are the reservoir for many harmful constituents, elemental and biological including heavy metals and trace metals. Chemical speciation is the process of determining and identifying specific chemical species or binding forms. It allows one to determine the availability and mobility of the metals in order to understand their chemical behaviour and fate. Crustal enrichment factors (EF) of elements are frequently used to determine the degree of modification in studies of atmospheric aerosols. If an enrichment factor is greater than unity, this indicates that the metal is more abundant in the sample relative to that found in the earth’s crust. High EF value (>10) were observed for Pb, Cd, Ba, and Zn suggesting substantial contribution from non-crustal source. Pb and Cd were the most enriched element in the Harmattan dust suggesting their dominant anthropogenic origin
