AB The analysis of plastics and related chemical compounds, such as plasticizers, flame retardants, and micro- ornanoplastics, often requires working at trace levels, where even minimal contamination can significantly affectresults. However, many of these target analytes are also present in common laboratory materials and environ-ments, increasing the risk of cross-contamination. We identified six major cross-contamination pathwaysfrequently found in analytical workflows: (I) laboratory materials, (II) environmental contamination, (III) humanhandling and manipulation, (IV) solvents and reagents, (V) cleaning and sample preparation, and (VI) instru-mental and system-related contamination. For each of these, preventive measures and good laboratory practicesare suggested based on both experimental experience and examples in the literature. As a general recommen-dation, procedural blanks should be included throughout the analytical process, and contamination risks shouldbe anticipated as early as the experimental design stage. This work provides a structured reference to supportmore reliable and reproducible data generation in the analysis of plastic-related contaminants. Researchers arefurther encouraged to evaluate contamination risks throughout the workflow and to report them transparently intheir publications.
