Water treatment – Why is it a regulatory challenge for plant protection products in the EU?

Regulation (EC) No 1107/2009 [1] lays down the rules for the authorisation of plant protection products in Europe with the aim of protecting humans and the environment. It is known that during primary disinfection processes for central water treatment (e.g. ozonation, chlorination) certain active substances included in plant protection products and their metabolites have the potential to form unwanted by-products with e.g. toxic, carcinogenic and genotoxic characteristics.

Currently water treatment is only addressed at active substance level. It remains largely unclear how the topic can be approached for product registrations and how metabolites can be realistically addressed.
The development of a guidance document is gaining speed this autumn: EFSA and several Member States are working on a scoping document to complete a previous UK guidance draft. It is intended to share the outcome on Member State level for further commenting and discussion of the next steps by end of the year [5].
With the implementation of such a guidance document it can be expected that other chemical sectors, e.g. industrial chemicals or pharmaceuticals, would also need to set a spotlight on the topic.
