The presence of toxic metals on paper pulp and the migration of these metals to food from the food package is receiving significant attention. The final exposure levels for consumers depend on two main processes. First the potential of metals to bind paper pulp during manufacture. Second, the metal potential to migrate from paper to food during storage and use.Binding and unbinding processes are modelled...
Several assays have been carried out in order to study in detail the cadmium mobility from water to virgin pulp as previous step of cadmium mobility description from paper into food. Virgin pulp has been immersed in different concentration aqueous solutions at several temperatures and during short and long time. The absorbed cadmium amounts have been measured by atomic absorption spectroscopy. For...
