Analysis of metals content in polyethylene packaging materials in view of the existing legislation

Atomic spectrometry update: review of advances in the analysis of metals, chemicals and functional materials

“…In one of the few reports not involving solid sampling approaches, Kolasa et al described a method for the determination of trace heavy elements (Cd, Cr, Hg and Pb) in polyethylene packaging materials following microwave assisted digestion of the samples. 314 This paper is worth highlighting because of the novel approach used in the development of the sample pre-treatment procedure. Samples were rst analysed using SEM-EDS to give a total concentration of each analyte.…”

Release of thymol from plasticized poly(vinyl chloride)

“…An increase in interest in the application of polymer materials with the addition of active substances intended for contact with food has also been observed [3]. The production of new bioactive materials may cause authorization problems in the food industry, as well as affect recycling [8][9][10].…”
