ANSES may not provide VMAX. In this case, the above table shows ” does not exist Maximum voltage ».
ANSES was unable to establish VMAX because there was insufficient data to define health safety limits specific to this substance. This does not necessarily mean that the substance is highly toxic. ANSES may need to conduct new assessments if additional data are developed or made available.
Why are we seeing more overspending than in the past?
Over the past decade, health control of EDCH quality has continued to evolve in terms of the performance of analytical methods. In addition, more and more active substances and metabolites are being searched for. Finally, the uses of plant protection products will also evolve over time. This development is due on the one hand to plant protection practices and needs, and on the other hand to the evolution of the number and diversity of authorized substances. Indeed, for some uses this may lead to a restriction of product selection or an increase in the use of certain active substances.
By combining these different factors, control measures reveal that regulatory quality limits are exceeded more often than in the past, requiring management actions to restore the quality of distributed water.
What are EDCH-related metabolites and who evaluates them?
According to European Directive 2020/2184, ” A pesticide metabolite is considered to be related to EDCH if there is reason to believe that it has intrinsic properties comparable to those of the parent substance in terms of target pesticide activity, or that it has a health benefit (either by itself or through its transformation products). .consumer risk ».
When a metabolite is considered to be related to EDCH, it must comply with There is the same alertness and the same regulatory measures as active substances found in tap water.
Europe has not yet defined standards and assessment methods for establishing the relevance of pesticide metabolites in EDCH, leaving it to each country to define it themselves. In France, relevance is assessed by ANSES or is not a metabolite of EDCH.
At the request of the DGS, ANSES proposed in January 2019 a method for identifying among pesticide metabolites those metabolites considered relevant to consumer health concerns and requiring priority attention.
The approach used by ANSES For drinking water only : Its focus is on protecting human health and preventing the risks posed by the ingestion of metabolites in tap water.
As a precaution, when applying this method, ANSES classifies metabolites as associated with tap water in two cases :
When the relevance of existing scientific knowledge can be determined When the standards retained by ANSES lack basic scientific data
