Abstract:
... Some components of plastic food packaging can migrate into food, and whereas migration studies of known components are required and relatively straightforward, identification of nonintentionally added substances (NIAS; unknowns) is challenging yet imperative to better characterizing food safety. To this aim, migration was investigated across 24 unique plastic food packaging products including plas ...

Abstract:
... Analysis of chemical residues in foods is a big challenge for developing countries due to lack of financial and professional resources needed to meet international quality standards for trade. However, the implementation of simple multiclass, multi-residue methods in monitoring programs can provide significant benefits to save cost, time, and labor. The aim of this project was to investigate the “ ...
... Potential contamination of food with chemicals migrating from food packaging is an important, yet under-investigated area of food safety. In this study, we examined chemicals migrating from common paper-based food packaging: pizza boxes and pizza box liners, butcher paper and liquid egg containers. Migration tests were conducted with a food simulant for 10 days, and migrated chemicals were identif ...

This study was aimed to investigate migration of chemicals from plastic FCMs used for microwave and conventional oven heating. Migration tests were conducted for samples of microwave trays, microwave oven bags, and oven bags. GC- and LC-Orbitrap mass spectrometry (MS) was used for ...
... A fast screening approach for simultaneous detection of twelve pesticides and seven mycotoxins in food and feed samples using flow injection (FI) mass spectrometry (MS) was developed and evaluated. Ten selected pesticides represented five pairs of structural isomers to challenge their MS differentiation without chromatographic separation. Samples of cereals/grains and animal feed were prepared usi ...

Abstract:
... Organophosphate esters (OPEs) are chemicals extensively used as plasticizers and flame retardants in commercial and consumer products. In this study, we developed and validated a method for the analysis of 13 common OPEs in meat (chicken, pork, and beef) and fish (catfish and salmon) to study their occurrence in those foods in the United States. The method was based on QuEChERS extraction with ace ...

A high throughput method for simultaneous determination of 200 pesticides and 65 environmental contaminants: polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs), polybrominated diphenyl ethers (PBDEs) and other flame retardants, was developed and validated in cattle, swine and poultry muscle tissues. The method was based on sample preparation with QuEChERS extraction followed ...

Abstract:
... The goal of this study was to develop and validate a new method for simultaneous determination of 106 veterinary drugs and 227 pesticides and their metabolites plus 16 polychlorinated biphenyls (PCBs) at and below their regulatory levels established for catfish muscle in the European Union and U.S.A. To do this, two different QuEChERS-based methods for veterinary drugs and pesticides and PCBs were ...

Abstract:
... In routine monitoring of foods, reduction of analyzed test portion size generally leads to higher sample throughput, less labor, and lower costs of monitoring, but to meet analytical needs, the test portions still need to accurately represent the original bulk samples. With the intent to determine minimal fit-for-purpose sample size, analyses were conducted for up to 93 incurred and added pesticid ...

Abstract:
... In this work, a new mega-method of sample preparation called “QuEChERSER” (more than QuEChERS) is being presented for the first time. Fast, efficient, and cost-effective analysis of chemical contaminants in meat is useful for international trade, domestic monitoring, risk assessment, and other purposes. The goal of this study was to develop and validate a simple high-throughput mega-method for res ...
... In the present study we examined spatial and seasonal trends in the levels of a wide suite of semi-volatile organic compounds (SVOCs) in brown trout (Salmo trutta) and mottled sculpin (Cottus bairdii) in East Canyon Creek, Utah, USA, an effluent-dominated stream during summer months. Fish samples were collected from four sampling sites, including one reference site upstream, and three sites at inc ...
