NIAS in Plastic Food Contact Materials
Introduction
Plastics are more than complex mixture of polymers in which non intentionally products are also added which is well known as NIAS (non-intentionally added substance). Impurities, degrade products and byproducts can be formed during reaction and are well known examples of NIAS products. Plastic chemicals such as bisphenol and phthalates have been detected in the US for more than 90%. Indeed plastics chemicals are considered as harmful products for humans as well as for nature. A disruption of chemicals of the endocrine system contributes to a wide range of adverse health effects to humans which links to exposure of BIS and phthalates.
Why it matters?
Health Risks: Notably, BIS and phthalates also act as MDCs (Metabolism disrupting chemicals). MDCs promote obesity, type 2 diabetes or other metabolic disorders basically increase in non communicable diseases. As far as it concerns, metabolic disruption can be mediated via nuclear receptors. Plastic products can be a source of endocrine disrupting chemicals and MDCs.
PLS Regressions for toxicity analysis: Characterization of chemical mixture extracted from plastic food contact articles (FCAs) in a set of reporter-gene assays covering pregnane X receptor (PXR), peroxisome proliferator-activated receptor γ (PPARγ), and estrogen receptor α (ERα). PLS regressions could be an approach to handle the large chemical complexity present in the FCAs and lead to explore a connection between the chemical and the receptor activity of the samples.
Implications
Plastic food packaging can contain chemicals which interfere with energy homeostasis and metabolic functions. Food packaging made up of Polyvinyl chloride (PVC) ,Polyurethane (PUR) and Low density polyethylene have induced effects, also most of the methanolic extracts of polymer samples activate most receptors. This article is just to highlight the importance of analyzing the toxicity of harsh chemical mixtures in finished plastic products. PLS regressions are useful to detect chemical features with the observed receptor activity. This is a major concern towards chemical complexity of chemicals in plastic finished products. There is also limited knowledge of compounds that have been found in the plastic. Active compounds can be further investigated to enable better monitoring of human exposure and its toxic effects.
The safety of plastic products can be significantly improved with a better characterization of products.
Conclusion
From NIAS to established contaminants like bisphenols and phthalates, these substances disrupt hormone systems and metabolic health, increasing risks for chronic diseases. The safety of plastic products requires enchanced analysis using PLS regressions to enable monitoring and protection of human health in world full of plastics.
We have to continue research to fill knowledge gaps for health. A laboratory assay plate, symbolizing hormone receptor testing.
Improved characterization of plastic will lead to enable better regulatory actions and contribute to safer product development. Our understanding of these hidden toxicants is essentia for safeguarding ecosystems, and promote sustainable alternatives in plastic usage.
