On December 20, 2020, Hermabessiere, Ludovic; Receveur, Justine; Himber, Charlotte; Mazurais, David; Huvet, Arnaud; Lagarde, Fabienne; Lambert, Christophe; Paul-Pont, Ika; Dehaut, Alexandre; Jezequel, Ronan; Soudant, Philippe; Duflos, Guillaume published an article.Name: 2,4-Di-tert-butylphenol The title of the article was An Irgafos 168 story: When the ubiquity of an additive prevents studying its leaching from plastics. And the article contained the following:
Plastic pollution is a source of chem. to the environment and wildlife. Despite the ubiquity of plastic pollution and thus plastic additive in the environment, plastic additives have been studied to a limited extend. As a prerequisite to a study aiming to evaluate the leaching of a common additive used as an antioxidant (Irgafos 168) from polyethylene microparticles, an inventory of the potential background contamination of the laboratory workplace was done. In this study, Irgafos 168 (tris(2,4-ditert-butylphenyl) phosphite) and its oxidized form (tris (2,4-ditert-butylphenyl) phosphate) were quantified in different laboratory reagents, including the plastic packaging and the powders, using Pyrolysis-GC/MS. At least one form of Irgafos 168 was detected in all tested laboratory reagents with higher concentrations in caps and bottles as compared to the powders. Addnl., oxidized Irgafos 168 was also found in the reverse osmosed and deionized water container used in the laboratory The same profile of contamination, i.e. higher concentration of the oxidized form and higher concentrations in acidic reagents, was observed when comparing the reagent and their resp. containers suggesting that the additive is leaching from the container into the powder. Overall, this study demonstrates that the antioxidant additive Irgafos 168 is ubiquitous in the laboratory workplace. Plastic additives such as Irgafos 168 can therefore largely interfere and biased ecotoxicol. and toxicol. studies especially using environmentally relevant concentrations of microplastics. The source, fate and effects of plastic additive from plastic debris should be carefully considered in future studies that require setting up methods to overcome these contaminations. The experimental process involved the reaction of 2,4-Di-tert-butylphenol(cas: 96-76-4).Name: 2,4-Di-tert-butylphenol
