AB Lead (Pb) and cadmium (Cd) have been detd. in six new environmental std. ref. materials (SRMs) using isotope diln. inductively coupled plasma mass spectrometry (ID ICP-MS). The SRMs are the following: SRM 1944, New York-New Jersey Waterway Sediment, SRMs 2583 and 2584, Trace Elements in Indoor Dust, Nominal 90 mg/kg and 10,000 mg/kg Lead, resp., SRMs 2586 and 2587, Trace Elements in Soil Contg. Lead from Paint, Nominal 500 mg/kg and 3000 mg/kg Lead, resp., and SRM 2782, Industrial Sludge. The capabilities of ID ICP-MS for the certification of Pb and Cd in these materials are assessed. Sample prepn. and ratio measurement uncertainties have been evaluated. Reproducibility and accuracy of the established procedures are demonstrated by detn. of gravimetrically prepd. primary std. solns. and by comparison with isotope diln. thermal ionization mass spectrometry (ID TIMS). Material heterogeneity was readily demonstrated to be the dominant source of uncertainty in the certified values.
