Abstract
Trace concentrations of cadmium and lead have been determined in dissolved samples of National Research Council of Canada Marine Certified Reference Materials BCSS 1 Coastal Marine Sediment, DORM 1 Dogfish Muscle and TORT 1 Lobster Hepatopancreas by furnace atomisation plasma emission spectrometry. No spectral interferences were evident at either the Cd 228.8- or Pb 217.0-nm lines. Matrix interferences were effectively compensated for by the method of additions, leading to good agreement between the analytical results and the certified values. Estimated procedural detection limits for the determination of Cd and Pb in BCSS 1 are 68 ng g–1 and 3.1 µg g–1, respectively, for an integrated signal response.
