“…Three blanks per experiment were included: a) procedural blanks to assess the contamination during the laboratory operations; b) material blanks to assess the possible contamination due to the lter material; c) system blanks to assess the contamination of vials and instruments; 3) Data analysis and ngerprinting: all the mass spectra were corrected for blank signal, and masses below the 3σ detection limit were not considered for the analysis. The ngerprinting was then performed by four algorithms using a high number of ions (40) with m/z > 120, following Materić et al, 2020. Procedural blanks were analyzed along with mussel samples. In blank samples, all the size ranges tested showed plastic presence ( ngerprinting output provided in Supplementary material).…”

Microplastics (MPs) and nanoplastics (NPs) (MNPs) are hazardous to ecosystems, wildlife, and through seafood, also for human health. Due to biological, chemical, and physical characteristics, NPs can slip through cell membranes, being even more toxicologically important than MPs. Thermal Desorption - Proton Transfer Reaction - Mass Spectrometry (TD-PTR-MS) was used to analyse mussels from the Apulian region, Italy. All the analysed organisms have NPs (values ranging from 10 ng MNPs/ DW mg to 187 ng MNPs / DW mg). The highest mass of plastics was detected in the size groups > 2,2 µm (218 ng MNPs / DW mg) and 20–200 nm (187 ng MNPs / DW mg). An upscaling we performed estimated that people in Europe could ingest more than 2 mg of NPs per year through seafood consumption. The detected presence of nanoplastics in farmed mussels here presented contributes to establishing a baseline for monitoring these pollutants.
