Conclusion on classification

Acute toxicity data for the test item are available for three trophic levels (fish, daphnia, algae). The lowest L(E)C50 for Daphnia magna, i.e., the 48-h EC50of 0.56 mg/L (based on dissolved test item concentration; geometric mean measured concentration), was observed in a GLP-conform standard test according to OECD 202 and is selected as acute reference value for classification.


 


The for one trophic level (algae) available chronic 72-h ErC10 of 0.56 mg/L (based on dissolved test item concentration; geometric mean measured concentration) for the effect of the test item on the growth rate of Desmodesmus subspicatus in a GLP-conform standard test according to OECD 201 is selected as long-term reference value for classification- Further, to conclude on the long-term aquatic hazard potential, the lowest acute L(E)C50of 0.56 mg/L for Daphnia magna, the readily biodegradability and the log Kow of 5.3 were considered.


 


Acute (short-term) aquatic hazard:


 


48-h EC50 0.56 mg/L


 


Since the lowest acute L(E)C50 is ≤ 1 mg/L, classification for ACUTE/SHORT-TERM AQUATIC HAZARD Category 1 with an acute M-factor of 1 is required.


 


Chronic (long-term) aquatic hazard based on chronic, acute data and environmental fate of the product:


72-h EC10 0.56 mg/L (algae)


48-h EC50 0.56 mg/L (Daphnia)


readily biodegradable


log Kow: 5.3


 


Since long-term data are available for algae only, the lowest acute L(E)C50 for invertebrate and fish is ≤ 1mg/L and the log Kow is ≥ 4,classification for CHRONIC/LONG-TERM AQUATIC HAZARD Category 1 with a chronic M-factor of 1 is required.


 


According to Regulation (EC) No. 1272/2008 and subsequent adaptations, the test item classifies as Acute (short-term) aquatic hazard, Category Acute 1 (H400: Very toxic to aquatic life) and Long-term aquatic hazard, Category Chronic 1: (H410: Very toxic to aquatic life with long lasting effects), with an acute and chronic M-factor of 1.
