Determination of lead in airborne particulates in Chicago and Cook County, Illinois, by atomic absorption spectroscopy

Assessment of the Impact of Opencast Chrome Mining on the Ambient Air Concentrations of TSP, Cr, Ni and Pb Around A Mining Complex in Northern Finland

“…In this context it is worth noting, that Yamashige et al [18] have reported the volatilization of Pb at high temperatures during the alkali fusion procedure. This phenomenon has also been reported in other corresponding studies [26][27][28]. However, in this context the alkali fusion procedure had to be used, because according to Yamashige et al [18], and Wang et al [16,29] low recoveries for Cr are expected by Acid decomposition methods.…”

Dry ashing of airborne particulate matter on paper and glass fiber filters for trace metal analysis by atomic absorption spectrometry

“…The determination of trace metals in particulate matter by atomic absorption spectrometry (aas) (Morgan and Homan, 1967;West, 1968) usually involves the initial destruction of organic matter in the sample followed by acid dissolution of residues. Dry ashing at high temperatures, as a method of oxidizing organic matter on glass filters, has been ruled out by some investigators (Burnham et al, 1969(Burnham et al, , 1970; Kneip et al, 1970;Morgan and Homan, 1967) because of the observed losses of low-melting metals. The most frequent explanation offered for these losses has been the volatilization of metals at high temperatures.…”

Trace Metals in Atmospheric Particulates and Atomic Absorption Spectroscopy

“…In recent years, atomic absorption spectrometry has been used in the analysis of trace metals in atmo- spheric particulates (21)(22)(23)(24)(25)(26)(27). Chief reasons for this trend include less sample preparation, selectivity, sensitivity, and relatively simple operating techniques.…”
