Migration of Heavy Metals from Printing Products for Children
The method of inversion voltammetry determined the amount of Zn, Cd, Pb, Cu and Hg, migrating to bidistilled water from publishing products for children. It is established that Zn, Pb and Сu stand out from all studied samples. Cadmium and mercury were not found in the extracts of two of the nine samples of paper studied. The contents of zinc and lead do not exceed the requirements of technical normative legal acts. The total migration of heavy metals from samples of the studied paper publishing products for children does not exceed 158,39 mg/kg, 0,730 mg/cm2 and 0,37 mg/dm3.
