The Pb, Cd, F, Al, Cr, Cu, Fe, Mn, Mo, Ni, Ti, and Zn content of 20 commercial bonemeal supplements was determined. Samples were mineralized with nitric and perchloric acids prior to determination of all elements except F, for which a diffusion method was used. Pb and Cd were determined by differential pulse anodic stripping voltammetry, F was measured using an ion selective electrode, and all other elements were determined by inductively coupled argon plasma spectroscopy. The mean recoveries of Pb and F were 97 and 99%, respectively. The concentration range of Pb was 1.5 to 8.7 ..mu..g/g. Cd was quantitated in only one sample at a level of 2.5 ..mu..g/g; all other samples were estimated to contain < 0.05 ..mu..g Cd/g. The concentration of F ranged from 261 to 921 ..mu..g/g. 3 tables.
