6.3 Risk characterization and analysis

Parent topic: 6 Risk Characterization

6.3.1 Prediction of discharge and environmental concentrations

 The Predicted Environmental Concentrations (PEC) should be predicted for all substances relevant for the risk assessment preferably using the latest MAMPEC model. The input parameters for the substance properties, the environment and the emission should be stated here. To be able to recalculate the MAMPEC results, screenshots of the input screens are helpful. If no information on the degradation rates is available, no degradation should be assumed in MAMPEC. It should be declared if that was the case. To be able to calculate the PEC/PNEC ratios, the environmental concentrations (maximum concentration) for all substances relevant for the risk assessment should be noted in this section.

6.3.2 Effects assessment

 A short summary of the data for ecotoxicity should be provided.

6.3.3 Effects on aquatic organisms

 Predicted No Effect Concentrations (PNEC) should be derived using the appropriate assessment factors (AF) according to TGD (section 3.3.1.1). The chosen AFs should be discussed. A tabular overview on the data is desirable.

6.3.4 Comparison of effect assessment with discharge toxicity

 A short discussion is eligible whether the discharge toxicity shows any unexpected effects that cannot be explained by the toxicity data of the single substances.
