Me. Conti et al., HEAVY-METALS AND OPTICAL WHITENINGS AS QUALITY PARAMETERS OF RECYCLEDPAPER FOR FOOD-PACKAGING, Journal of food processing and preservation, 20(1), 1996, pp. 1-11
The aim of the present work was to evaluate the suitability of recycli
ng papers for their possible use in the field of food packaging. There
fore, the amount of some heavy metals (Pb, Cd, Cr, Cr VI, Hg) and the
presence/migration of optical whitenings in 14 samples of recycled pap
ers was determined. The obtained results showed that the considered pa
rameters may be suggested to characterize recycling papers.
