Additional information

Adequate chronic toxicity data is not available for Yellow LF 6881, therefore the aquatic toxicity assessment and classification are based on the short-term toxicity data available.

Yellow LF 6881 is not rapidly degradable. It has a negative log Kow lower, let to expect a low potential for bioaccumulation; in addition.

The substance was tested for toxicity potential on fish, aquatic invertebrates and algae. No acute toxicity was recorded in none of the experiments conducted: the LC50 (96h) for freshwater fish resulted to be higher than 100 mg/l, as well as the EC50 (48h) for aquatic invertebrates; regarding freshwater algae, the ErC50 (72h) was found to be 130.18 mg/l, the EyC50 (72h) 27.60 mg/l (nominal) and the NOEC (72h) 6.25 mg/l (nominal), for both growth rate and yield.

Thus, the outcomes from the short-term tests performed on the three trophic levels suggest that is not harmful/toxic for aquatic life.

The test substance resulted to be no harmful-toxic for activated sludge and not negatively impacting the microorganism activity; thus, it is deemed to be not able to affect the sewage treatment plants systems function.

Direct releases to air and/or sediment and/or soil are considered to be not relevant, on the basis of the substance usages describe into the IUCLID section 3.3; in addition, the physicochemical properties support the expectation of low relevance of the mentioned compartments.

The primary source of possible substance environmental release is represented by industrial waste waters.

Conclusion on classification

Adequate chronic toxicity data is not available for Yellow LF 6881, therefore the aquatic toxicity assessment and classification are based on the short-term toxicity available data.

Yellow LF 6881 is a very water soluble substance, not rapidly degradable. In addition, it is characterized by a negative log Kow, which let to expect a low potential for bioaccumulation.

No L(E)C50 value was recorded at concentration equal/lower than 1 mg/l, thus the classification criteria for acute (short-term) aquatic hazard (category 1) of the CLP Regulation (EC) No 1272/2008 are not met.

In addition, no acute toxicity (i.e. L(E)C50) was recorded in none of the experiments conducted, up to the concentration of 100 mg/l; thus the classification criteria for long-term aquatic hazard (categories 2/3/4) of the CLP Regulation (EC) No 1272/2008 are not met.

In conclusion, the outcomes of the tests performed on the three trophic levels showed that Yellow LF 6881 is not harmful/toxic for aquatic life.
