Cadmium is one of the most important toxic elements to be determined in environmental samples. Cd has proved, however, to be a difficult element to determine with good precision and relative accuracy. This is shown by the results of recent intercalibration exercises. (a) In the Baltic Sediment Intercalibration Exercise, Brtigmann and Niemisto (1987) found deviations in reported Cd results unacceptable. Relative standard deviations (rsd's) were 48 % and 63 % for for the two intercalibration samples. (b) In the National Research Council of Canada (NRCC) intercalibration (NRC MS1/TM), Berman and Boyko (1985) found that less than one-third of the 35 laboratories submitting Cd values appeared competent in handling samples at the 0.6 mg/kg level. (c) In the ICES First Intercalibration Exercise on the Trace Metals in Marine Sediments (1/TM/MS) report, Loring (1987.....
