Conclusion on classification

SUMMARY OF AVAILABLE DATA (key values)

Acute toxicity to aquatic organisms (pelagic):

- Freshwater fish (Danio rerio): 96h-LC50 > 12.9 mg solid content/L (limit test);

- Marine fish (Scophthalmus maximus): 96h-LC50 > 4.8 mg solid content/L (limit test);

- Marine crustacean (Acartia tonsa): 48h-EC50 = 20 mg active content*/L;

- Freswater algae: no data;

- Marine algae (Skeletonema costatum): 72h-EC50 = 5.1 mg active content*/L.

*As an EC50 value expressed in solid content was not reported, the EC50 value expressed in active content was used as a worst-case for the assessment.

Chronic toxicity to aquatic organisms (pelagic):

- Fish: no data;

- Marine crustaceans: no data;

- Freshwater algae: no data;

- Marine algae (Skeletonema costatum): 72h-NOEC = 3 mg active content*/L.

*As a NOEC value expressed in solid content was not reported, the NOEC value expressed in active content was used as a worst-case for the assessment.

Other ecotoxicity data:

- Aquatic microorganisms (freshwater, activated sludge): 3h-EC50 = 1182.7 mg solid content/L and 3h-EC10 = 379.5 mg solid content/L;

- Sediment organisms (marine water, amphipods): 10 -LC50 > 4408.5 mg active content/L.

Environmental fate:

- Rapidly degradable in the environment (more than 60% mineralization in 28 days in a biodegradation test in seawater);

- Low bioaccumulation potential (based on log Kow < 4).

All effective concentration are expressed in solid content (or in active content) and are relevant for the REACh-registered substance (= active content + minor constituents + impurities). According to the CLP criteria for hazard classification, the substance EC 242-893-1 does not have to be classified for acute and chronic environmental hazards.
