Additional information
The PNEC for freswater is calculated with the use of a factor of 1000 on short-term toxicity data which is a conservative and protective factor. For PNECsediment and soil the equilibrium partitioning method (EPM) was used with a Koc value extrapolated from the Log Kow which was difficult to assess according to the very low solubility of the dye. As exposure using the model EUSES implemented in Chesar is also using the same value of Koc the ratio PEC/ PNEC is considered only as a screen for assessing the level of risk to sediment/soil dwelling organisms .
For substances with a log Kow greater than 5 (or with a corresponding Kpsed) the equilibrium partitioning method is used in a modified way in order to take account of possible uptake via ingestion of sediment or by soil ingestion. Thus the resulting PEC/PNEC ratio should be increased by a factor of 10 for these compounds.
Conclusion on classification
- ErC50 (72h) algae = 0.0053 mg/L (geometric mean of the measured concentrations) with 95% confidence limits of 0.048 - 0.0057 mg/L
- EC50 (48h) daphnies = 0.011 mg/L (measured concentrations) with 95% confidence limits of 0.0094 - 0.013 mg/L
- NOECchronic fish = 40 µg/L (nominal concentrations, based on measured concentrations showing a stable exposure concentration within 80 -120% of nominal over the entire exposure period)
- EC50 microorganisms: no study available, but during the biodegradation test, no microbiological toxicity was observed.
The results from the aquatic toxicity studies are as follows:
The classification for acute toxicity based on the lowest short term data for algae (EC50 = 5.3 µg/l) is Aquatic Acute 1 H400 with a M factor of 100. With no biodegradation the classification Aquatic chronic 1 is also relevant with a M factor = 100.
Based on the results from the short-term aquatic toxicity tests and since the substance is not biodegradable and has a log Kow of > 4, the substance is classified as Aquatic Acute 1 (Hazard statement H400 - Factor M = 100) and Aquatic Chronic 1 (Hazard statement: H410 - Factor M = 100) according to the CLP Regulation 1272/2008.
