Content of the Opinion:
The dossier on Environmental Quality Standards for “Nicosulfuron” was reviewed by the SCHEER according to the general mandate on EQS dossiers.
The SCHEER endorses the MAC-QSfw,eco =0.23 μg L-1, and the AA-QSeco,fw =8.7 10-3 μg L-1 derived with a deterministic procedure. The SCHEER agrees with the decision of not performing the probabilistic approach due to the scarcity of data.
For saltwater, the SCHEER endorses the deterministic MACsw, eco of 0.023 μg L-1, and the AA-QSsw, eco of 8.7 10-4 μg L-1.
The SCHEER agrees that an EQS for sediments, as well as for secondary poisoning, is not necessary.
For human health, the SCHEER endorses a QSbiota,hh food = 120 mg kg-1 and the adoption of the general drinking water standard for pesticides (0.1 μg L-1).
