The application of inductively coupled plasma mass spectrometry (ICP-MS) to the determination of eight trace metals in a coastal seawater reference material is described. Accurate calibration has been achieved for Mn, Co, Ni, Cu, Zn, Cd, and Pb by standard additions techniques, while stable isotopes dilution has been applied for Cr, Ni, Cu, Zn, Cd, and Pb. In both cases the race metals were separated from the seawater and concentrated 50-fold by adsorption on silica-immobilized 8-hydroxyquinoline prior to instrumental determination. Detection limits are in the range from 0.2 to 2 ng L/sup -1/, low enough to permit the analysis of even open ocean samples. 12 references, 4 figures, 3 tables.
