This upload contains the raw data associated with the publication cited below. The data set includes that mass spectral data of the plastic extracts and migrates analyzed using UPLC-QTOF-MSE. For experimental details on the nontarget analysis, see the publication mentioned above. The data uploaded here are in a Waters .raw file format that can be accessed using Waters software (MassLynx, Progenesis etc.) or converted in the open MZML format using msConvert in ProteoWizard (http://proteowizard.sourceforge.net). Each file contains the individual mass spectral data of a sample. They are labelled with "EXT" for plastic extracts and "MIG" for plastic migrates. The sample names denote the polymer type of the plastic product. Further information on the samples can be found in Table 1 of the publication this data set supplements.
