Description

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
Contact:SANTE-C2-SCHEER@ec.europa.eu
On request from: European Commission
Adopted on: 25 March 2022

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

The SCHEER endorses the MAC-QSfw,eco = 0.34 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 = 0.034 µg L-1.

The SCHEER endorses the AA-QSfw, eco = 0.01 µg L-1, derived with a deterministic procedure. The probabilistic procedure is not applied due to the scarcity of data.

For saltwater, the SCHEER endorses the deterministic AA-QSsw,eco = 0.001 µg L-1.

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

For human health, the SCHEER endorses a QSbiota,hh = 12 mg kg-1 and the adoption of the general drinking water standard for pesticides (0.1 µg L-1).
