>It is particularly important to note that all tissues removed during the autopsy came into contact with plastic
>In addition, all organs were cut with scalpels on plastic boards made of PE for storage until examination and then stored in plastic containers filled with formalin
>PE was identified as the main component of the plastic fraction in all tissues examined
>Here, several pyrolysis fragments are normally used for each polymer. These fragments break down again in the mass spectrometer into several fragment ions, the frequency (intensity) of which can be used to determine the concentration of the polymer. In order to rule out the possibility that signals of other, non-polymeric compounds (in the case of PE, these are, for example, the alkyl chains of fatty acid residues) overlap with these signals, they should occur in certain ratios.
>Although pyrolysis fragments and ions are named in the publication for the identification and quantification of the respective polymers, it is not clear which specific ions were used for the important quantification, nor what the ratio of the signals to each other is. Thus, interference from non-polymeric components and a significant overestimation of the polymer content cannot be ruled out.
