Additional information
PNECaqua freshwater
PNEC=0.0012 mg/L
Assessment factor: 1000
Short-term toxicity studies in fish, daphnia magna and algae are available. The PNEC can be derived on the basis of these three short-term studies. An assessment factor of 1000 is applied in line with chapter R.10 of the guidance documents (ECHA 2008). The lowest EC50 of 1.2 mg/L was observed for daphnia magna. The PNECaquais therefore 1.2 mg/L / 1000 = 0.0012 mg/L.
PNECaqua marine
PNEC=0.00012 mg/L
Assessment factor: 10000
Short-term toxicity studies in fish, daphnia magna and algae are available. The PNEC can be derived on the basis of these three short-term studies. An assessment factor of 10000 is applied in line with chapter R.10 of the guidance documents (ECHA 2008). The lowest EC50 of 1.2 mg/L was observed for daphnia magna. The PNECaqua,marineis therefore 1.2 mg/L / 10000 = 0.00012 mg/L
PNECaqua intermittent
PNEC=0.012 mg/L
Assessment factor: 100
Short-term toxicity studies in fish, daphnia magna and algae are available. The PNEC can be arrived on the basis of these three short-term studies. An assessment factor of 100 is applied in line with chapter R.10 of the guidance documents (ECHA 2008). The lowest EC50 of 1.2 mg/L was observed for daphnia magna. The PNECaqua,intermittentis therefore 1.2 mg/L / 100 = 0.012 mg/L
PNECsediment freshwater
PNEC= 0.012 mg/kgdw
Extrapolation method: partition coefficient
The equilibrium partitioning method (EPM) was applied using the lowest reported Koc of 64.4. This leads to a worst case estimation of the PNECsediment of 2.62E-03 mg/kgwwt, corresponding to 0.012 mg/kgdw.
PNECsediment marine
PNEC= 0.0012 mg/kgdw
Extrapolation method: partition coefficient
The equilibrium partitioning method (EPM) was applied using the lowest reported Koc of 64.4. This leads to a worst case estimation of the PNECsediment of 2.62E-04 mg/kgwwt, corresponding to 0.0012 mg/kgdw.
PNECsoil
PNEC= 1.71E-03mg/kgdw
Extrapolation method: partition coefficient
The equilibrium partitioning method (EPM) was applied using the lowest reported Koc of 64.4, the highest reported water solubility of 2.76 g/L, the vapour pressure of 4.3 Pa at 25°C and a molecular weight of 148 g/mol. This leads to a worst case estimation of the PNECsoil of 1.51E-03 mg/kgwwt, corresponding to 1.71E-03 mg/kgdw.
PNECstp
PNEC: 1.6 mg/L
Assessment factor: 100
One study on the toxicity to micro-organisms is available.The PNEC can be arrived on the basis of the EC50 derived in this study. An assessment factor of 100 is applied in line with chapter R.10 of the guidance documents (ECHA 2008). An EC50 of 160 mg/L was observed. The PNECaqua,marineis therefore 160 mg/L / 100 = 1.6 mg/L

Conclusion on classification
The substance is classified as regards ecotoxicological endpoints. It was found to be toxic to fish, aquatic invertebrates and algae but non-toxic also activated sludge in studies conducted to OECD guidelines.
The test material attained 16% degradation based on CO2 evolution after 28 days and 45% based on DOC removal. It is therefore not considered 'readily biodegradable' under the strict terms and conditions of OECD Guideline No 301B though under the physiologically relevant conditions of pH 1.2, 37.0 ± 0.5°C, the test material was determined to undergo essentially spontaneous hydrolysis and the Log Pow is <3.
The substance is therefore classified as regards it's possible long-term effects on the aquatic environment.
