Final Opinion


SCHEER WG on Water Framework Directive
SCHEER members: Marian Scott (Chair), Marco Vighi (Rapporteur), Thomas Backhaus, Teresa Borges, Peter Hoet, Pim de Voogt
External experts: Andrew Johnson, Jan Linders

On request from: European Commission
Adopted on: 25 March 2022

The dossier on Environmental Quality Standards for “Acetamiprid” was reviewed by the SCHEER according to the general mandate on EQS dossiers.

The SCHEER endorses the MAC-QSfw,eco = 0.16 µg L-1, derived with a deterministic procedure. The SCHEER agrees with the decision of not considering reliable the probabilistic approach due to the high degree of uncertainty.

For saltwater, the SCHEER endorses the deterministic MAC-QSsw,eco = 0.016 µg L-1.

The SCHEER does not agree with the proposal of the dossier of an additional AF of 5, besides the AF of 10. Therefore, SCHEER is of the opinion that a deterministic AA-QSeco,fw = 0.037 µg L-1 should be determined instead of the value of 0.0074 µg L-1 proposed in the EQS-dossier. The probabilistic procedure is not applied due to the scarcity of data.

For saltwater, the SCHEER proposes the deterministic AA-QSsw,eco = 0.037 µg L-1.

For sediment, the SCHEER endorsed the value of QSsedEqPdw = 0.26 µg kg-1dw obtained using the Equilibrium Partitioning method.

The SCHEER agrees with the decision of not deriving an EQS for secondary poisoning.

For human health, the SCHEER endorses a QSbiota,hh = 3.1 mg kg-1ww and the adoption of the general drinking water standard for pesticides (0.1 µg L-1).
