Description of key information
Harmful to aquatic life with long lasting effects; Aquatic Chronic 3, H412, according to the CLP Regulation (EC) 1272/2008
Additional information
Adequate chronic toxicity data is not available for Acid Green 040, therefore the aquatic toxicity assessment and classification are based on the short-term toxicity data.
Acid Green 040 is very water soluble, not rapidly degradable; in addition, it is characterized by a negative log Kow, indicating a low bioaccumulative potential.
According to the CLP Regulation (EC 1272/2008), acute aquatic toxicity is normally determined using a fish 96-hour LC50, a crustacean species 48-hour EC50 and/or an algal species 72- or 96-hour EC50; nevertheless it is also specified in the Regulation that data on other species (e.g. Lemna spp.) shall also be considered if the test methodology is suitable. These species cover a range of trophic levels and taxa and are considered as surrogate for all aquatic organisms.
Reliable data is available for Daphnia magna and Lemna minor species.
No L(E)C50 value was recorded at concentration equal/lower than 1 mg/l, thus the classification criteria for short-term aquatic hazard (category 1) of the CLP Regulation (EC) No 1272/2008 are not met.
Based on the available test results, the short-term effect level (L(E)C50) is identified in the range of 10 - 100 mg/l for both invertebrates and aquatic plant species; therefore, the classification criterion for long-term aquatic hazard (categories 3) of the CLP Regulation (EC) No 1272/2008 is met.
In conclusion, the outcomes of the tests performed suggest that Acid Green 040 is harmful to aquatic life with long lasting effects.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
