Inductively coupled plasma mass spectrometry has been investigated for the determination of trace elements in foods. The effects of the major elements in foods (Na, Mg, P, K, Ca) on the response of several trace elements found in foods (Al, Cr, Zn, Mo, Cd, Pb) were evaluated. Enhancement or suppression of response is generally less than 10% in the presence of 1000 mg L/sup -1/ of each major element added. The effects of mixed concomitants (Na, Mg, P, K, Ca) at concentrations of 0.1% and 0.2% total dissolved solids on Zn, Mo, Cd, and Pb at 0.01 and 0.10 mg L/sup -1/ were investigated. The greatest suppression observed with the mixed concomitant solutions was on the response of 0.01 mg L/sup -1/ Zn. Results are presented for dry ashed reference materials, which compare well with those reported by NBS.
