AI Article Synopsis
- PFASs are common environmental pollutants found in food sources like fish, fruits, and eggs, posing potential health risks through dietary exposure.
- A new method was developed to measure 18 PFASs in different types of eggs using advanced liquid chromatography and mass spectrometry, analyzing a total of 132 samples.
- Results indicated no significant differences in PFAS levels among organic, barn, and caged eggs, but children were found to have higher exposure levels compared to adults, raising concerns about exceeding the tolerable weekly intake when combined with other food sources.
Article Abstract
Per- and polyfluoroalkyl substances (PFASs) are ubiquitous environmental pollutants with the ability to uptake to food and feed. Among food, fish, fruits and eggs are considered as major contributors to human dietary exposure. A new method was developed and validated for the simultaneous determination of 18 PFASs in eggs using isotope dilution followed by ultrahigh performance liquid chromatography coupled to high resolution mass spectrometry. The analysis of 132 samples (organic, barn and caged eggs) was performed. Levels were always close to the detection limits and no significant difference emerged among the 3 groups. The highest PFAS concentration in eggs was used to estimate the dietary exposure of different Italian population groups. As expected, children were more highly exposed than adults due to lower body weight. This data suggests that the recent tolerable weekly intake of 4.4 ng kgb.w. could be exceeded when the cumulative intake arising from other food products is considered.

Currently, deacetylated chitin (chitosan) nanoparticles (CNPs) are successfully utilized in aquaculture practices. This trial demonstrates the efficacy of CNPs in combating diazinon (DZN) toxicity in African catfish, Clarias gariepinus, via monitoring hepato-renal function, serum immune trait, hormonal function, and hepato-renal antioxidant activity. Four groups were allocated as follows: a control group, a CNPs group (0.

A tiered intake assessment approach is presented and applied to derive estimates of maximum potential global propylene glycol (PG) intake from beverage sources. The US and UK markets served as surrogates for the world and the EU region, respectively, to determine the maximum potential exposure for PG in various subpopulations, including brand-loyal consumers. Conservative intake estimates for PG used in non-alcoholic beverages were calculated for toddlers less than 2 years (y), young children 3-9 y, adolescents 10-17 y, adults 18-64 y, elderly 65-74 y, very elderly 75+ y, based on assumed uses in high beverage consumption markets, leveraging either the 2-day food consumption data from the 2013-2016 US National Health and Nutrition Examination Survey or the 4-day food consumption data from the 2008-2017 UK National Diet and Nutrition Survey Rolling Programme.

Background: Carotenoids have been shown to have multiple health benefits, including antioxidant and anti-inflammatory. The data for the effect of dietary specific carotenoids on biological aging is limited. Our study aims to examine the association between dietary carotenoid intake levels and biological aging.
