Abstract

Selenium concentration in body fluids is a good index to establish human selenium status. This work discusses the determination of seleniumin serum by ETAAS using longitudinal Zeeman-effect background correction and combining the use of automated slurry sampling. The standard reference materials bovine serum (NIST, SRM 1598) and second-generationbiological freeze-dried human serum are analyzed to verify the accuracy and precision of this technique. The direct method proposed in thisstudy is used for the determination of selenium in human serum collected from healthy people of 19-25 years. The average accuracy values ofcertified reference serum samples and the recovery values of spiked samples indicate this method to be an efficient and rapid technique fordetermining selenium in biological samples.
