Exact excerpt

FTIR identified 54 microplastic spectral signatures across four major polymer types: polyethylene (PE), polypropylene (PP), polystyrene (PS), and polyvinyl chloride (PVC), linked to functional groups such as alkyl halides, carboxylic acids, aliphatic amines, and isothiocyanates. Site 5, an urban transit zone, recorded the highest polymer diversity (20 functional groups), followed by suburban Site 4 (17 groups).
