Integrated GC–MS and ATR–FTIR analysis of airborne microplastics captured by spider webs (opens in new tab)

Our study evaluated airborne microplastics (MPs) captured by spider webs (Agelenidae) in an urban environment (Wrocław, Poland). GC–MS was used to characterize extractable organic compounds linked to MPs, while ATR–FTIR spectroscopy enabled detection of polymer-related signals in solid residues after solvent extraction. All samples contained compounds associated with polymeric materials, including rubber- and silicone-related components, with rubber signals detected at all sites. No significa...
