Content of the Opinion:

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

The SCHEER endorses the MAC-QSfw,eco = 0.065 μg L-1, derived with a deterministic procedure and the MACfw, eco = 0.057 μg L-1, derived with a probabilistic procedure.

For saltwater, the SCHEER endorses the deterministic MAC-QSsw,eco = 0.0065 μg L-1.and the probabilistic MACsw, eco = 0.0057 μg L-1.

The SCHEER also endorses the AA-QSfw, eco = 0.0024 μg L-1, derived with a deterministic procedure, and the AA-QSfw,eco = 0.0068 μg L-1, derived with a probabilistic procedure and, for the marine environment, the deterministic AA-QSsw,eco = 0.00024 μg L-1and the probabilistic AA-QSsw,eco = 0.00068 μg L-1, may be endorsed.

The SCHEER agrees with the decision of not deriving an EQS for secondary poisoning, as well as for human health risk via consumption of fishery products.

For the exposure via drinking water, SCHEER agrees with the adoption of the general drinking water standard for pesticides (0.1 μg L-1).
