Plant protection products and their metabolites, which remain in the food as residues of an active treatment are determined by sensitive detection methods. This also applies for unwanted contaminations, which can enter the environment and therefore, also into foodstuffs, e.g. as a stocking in herbs (Pyrrolizidine alkaloids - PA), during disinfection/chlorination (perchlorate/chlorate), as a migration from plastics or in industrial emission (e.g. heavy metals) and are detectable.
Alongside the common screening processes DFG S19 and QuEchERS, many collection and individual methods are offered.
