Challenge test for analysing presence of contaminants before / after samples decontamination

Establish an artificial contamination method to prepare plastic samples (= challenge test) including determined concentration of contaminants, i.e. surrogate contaminants that have a variety of chemical and physical properties. The challenge test serves to check the performance of decontamination step of a recycling process removing same or similar contaminants as those of the challenge test.
