“…Additionally, OPAs may migrate from the packaging leading to contamination of the food packed [15][16][17][18]. As a result, the use of OPAs in plastics has become controversial and the assessment of their nature and toxicity is of utmost importance.…”

“…Irgafos® 168 (tris(2,4-ditert-butylphenyl) phosphite) (Figure 1) is a plastic additive mainly incorporated into Polypropylene (PP) and Polyethylene (PE) as an antioxidant (Dopico-García et al, 2007). It has been used in food packaging (Cherif Lahimer et al, 2017;Dopico-García et al, 2007), supposedly explaining its detection in frozen vegetable (Tanaka et al, 2003).…”

Plastic pollution is a source of chemical 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 (2,4ditert-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. Additionally, 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 respective 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 ecotoxicological and toxicological 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.
