). The injection repeatability was evaluated as the average relative standard deviation (R.S.D %) for five successive firings and was better than 4.4%for Cd and 5.4% Hg. The detection limits, evaluated by the 3s concept of calculation (n¼10), were of 10.2 mg kg1(0.9 mg L1) for Hg and 0.3 mg kg1(0.04 mg L1) for Cd
