Metabolites

Metabolites are chemical intermediates that arise during metabolism. For example, human metabolism produces many metabolites such as sugars or amino acids when it digests food. That is why material change is also called metabolism. Metabolites are also formed when plant protection products break down. Limit values determine how large the amount of active ingredient residues of plant protection products and their degradation products may be, for example in groundwater.

A distinction must be made between «relevant» and «non-relevant» metabolites. «Relevant» degradation products can have negative effects on people and the environment. It is therefore scientifically recognised that stricter limits apply to them than to «non-relevant» metabolites.

In the discourse about the use of pesticides, the quality of Swiss water is repeatedly called into question. Since very high safety and quality requirements are placed on drinking water in Switzerland, residues of pesticides and their relevant degradation products are very strictly regulated. Water quality in Switzerland is very high.
