Sažetak
Plastic has a great potential to become a marker horizon of human pollution in the Anthropocene era, an era of significant human impact on Earth’s geology, climate and ecosystems. An exponential increase in annual global plastics production from 1.7 million tons in 1950 to 359 million tons in 2018. has faced us with the new contaminant of emerging concern nano/micro-plastics (NMPs). NMPs present very different hazards, with four key areas of concern being: leaching of additives ; plastic particles as vectors for environmental contaminants and microorganisms ; indirect effects through actions at the lining of our guts or lungs ; and, for particles small enough to pass through biological barriers, direct effects within tissues. To ensure food safety and to protect consumers’ health, the presence of food contaminants must be investigated carefully. One contaminated food might, and mostly do, contain several types of NMPs. These particles differ in many ways, including chemical structure, size, shape and biological and chemical load on them. NMPs can be found in food because of environmental pollution but also, there is a growing interest in the possibility of release/leakage of NMPs from food packaging materials, such as tea bags, bottles etc. NMPs internalised by plants are another potential source of human exposure. Existing research on NMPs occurrence in food including the advantages and limitations of the analytical methods and their complementary for the comprehensive characterization of NMPs in food will be presented by the lecture. Special focus of the lecture are the unreacted residual monomers originating from the polymeric material and additives. Among them, bisphenol A (BPA), vinyl chloride, acrylamide and styrene are of greatest concern as representative of monomers and in the field of several hundreds of additives used in plastic production today phthalates, polybrominated diphenyl ethers, and heavy metals due to the greatest concerns arise from the leaching.
