The content of heavy metals in the solid toilet soap

Abstract

By stripping voltammetry method it was determined the maintenance of Zn, Pb, Cu and Hg in samples of 8 names of solid toilet soap. It was established that all studied samples of toilet soap contain Zn, Pb, Cu and Hg, and the maintenance of Zn exceeds the content of other heavy metals in tens and even hundreds of times. The maintenance of Pb in the studied samples of toilet soap is more than 3 times less than the size regulated by the SanPiN № 130-A RB. Only in insignificant quantities cadmium is found in two studied samples of toilet soap: NIVEA and CAMAY.
