Abstract
Influence of seawater salts on the determination of trace metals in rainwater by electrothermal atomic absorption spectrometry has been studied. From the results obtained for Cd, Cr, Cu, Ni, Pb and Zn, it appears that seawater salts at concentration levels eventually met in coastal rainwaters may induce important interferences if the choice of the experimental conditions ‐ pyrolytic tube with or without platform, peak height or peak area mode ‐ is not correct.
