Method on organic micropollutants (organic trace substances)
Not all substances are regulated in the Waters Protection Ordinance (WPO) and the toxicity of mixtures of different substances is not taken into account. Therefore, a VSA guideline for the assessment of the ecotoxicity of organic trace substances is being developed in parallel to the development of the enforcement aid.
The method on micropollutants consists thus of 2 documents (both in preparation):
- Substances with numerical requirements in Annex 2 of the WPO
- Evaluation of the ecotoxicity of organic trace compounds
