This dataset contains the raw data of the chemical analysis described in the associated publication (DOI: 10.1021/acs.est.3c08250), namely the mass spectral data of the plastic extracts analyzed using UPLC-QTOF-DDA. For experimental details on the nontarget analysis, see the Supporting Information of the publication. The data uploaded here are in the Waters .raw file format that can be accessed using Waters software (MassLynx, Progenesis etc.). Each zip file contains the individual mass spectral data of one sample. They are labelled with the sample name corresponding to the samples described in Table 1 of the publication. The sample names denote the polymer type of the plastic product. PB refers to the procedural blanks, MeOH refers to the methanol used as a solvent. These files can be easily converted into an mzML format using MSconvert in ProteoWizard (https://proteowizard.sourceforge.io/).
