North American Chemical Residue Workshop (NACRW)

Scientists at NACRW discussed using CE–MS to analyze highly polar agrochemicals.

During the North American Chemical Residue Workshop, scientists discussed predicting liquid chromatographic retention times to identify contaminants.

During a presentation at the North America Chemical Residue Workshop, scientists described a method for pesticide analysis using liquid chromatography-tandem mass spectrometry and gas chromatography-tandem mass spectrometry.

In a presentation at NACRW 2023, Yelena Sapozhnikova of the U.S. Department of Agriculture (USDA) explained that even though levels of per- and polyfluoroalkyl substances (PFAS) were found in everything from tomato packaging to cake paper in global samples, values were below the European Food Safety Authority (EFSA)’s maximum tolerable weekly intake (TWI).

Bjorn Berendsen of Wageningen University & Research said at NACRW 2023 that among more than 6,000 suspected per- and polyfluoroalkyl substances (PFAS), detailed information is known about relatively few.

Scientists studied the device for QuEChERSER sample preparation and both GC-MS/MS and LC-MS/MS analysis of pesticides in grapes, watermelon, and green beans.

During a session at the North American Chemical Residue Workshop, researchers discussed a method for detecting small amounts of pesticides in infant food.
