Abstract

The use of beekeeping products for thc fabrication of cosmetics and drugs requires to know the content of sorne toxic metals as As and Pb because they can be present as traces. In this paper was developed a procedure of digestion with HN03 concentrated, in creams and drugs for the determination of As and Pb. In case of As it was used the technique of hydride generation with detection by atomic absorption spectrometry and NaBH4 3 % as reductor in HCl 3 M medium. Pb was determinate by flame atomic absorption spectrometry. It was carried out a study of interferences in arder to determine the influence of the wombs in the determinations. The concentrations of As and Pb in the patterns are below of 0.8 and 10 µg/g, respectively. The accuray was checked by tests of recuperation getting security values between 95 and 105 %.
