Mitigation Factor 1.00 PNEC: 3.55 μg/L 7.3. Environmental Risk Assessment Based on the above predicted PEC and PNEC, the following Risk Quotient (Q = PEC/PNEC) has been calculated: Risk Assessment PEC PNEC Q μg/L μg/L Q - River 0.57 3.55 0.160 Q - Ocean 0.06 3.55 0.016 The risk quotient for discharge of effluents containing the notified chemical to the aquatic environment indicates that the notified chemical is unlikely to reach ecotoxicologically significant concentrations based on its annual importation quantity, use pattern and predicted ecotoxicological endpoints. Based on its low log Kow (log Kow = 3.0), the notified chemical is not expected to significantly accumulate in biota. Therefore, on the basis of the PEC/PNEC ratio, the maximum annual importation volume and the assessed use pattern, the notified chemical is not expected to pose an unreasonable risk to the environment.
