Environmental Analysis

Microplastics and nanoplastics have been identified in the lungs of wild birds using laser direct infrared (LDIR) chemical imaging and pyrolysis gas chromatography–mass spectrometry (Py-GC–MS), in the first multi-species evidence of these plastics in bird lungs.

David Megson from Manchester Metropolitan University in Manchester, UK, spoke to LCGC International about the latest developments in non-targeted analysis (NTA) of per- and polyfluoroalkyl substances (PFAS) in environmental matrices based on a recent systematic review paper he has collaboratively published (1).

Scientists from Tabriz University and the University of Tabriz explored cellulose acetate-UiO-66-COOH as an affordable coating sorbent for thin film extraction of biogenic amines from cheese and alcohol-free beverages using HPLC-MS/MS.

Using pyrolysis-gas chromatography and mass spectrometry, scientists from Fudan University and the Putuo District Center for Disease Control and Prevention detected and quantified microplastics in newborn stool samples.
