Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Conclusion on classification

Classification is based on biodegradation, bioaccumulation and aquatic toxicity data (acute and chronic). Since long-term values are only available for one trophic level (aquatic invertebrates), the classification scheme outlined in Table 4.1.0(b) (ii) and Table 4.1.0(b) (iii) of Regulation (EC) No 1272/2008 was followed.

 

Biodegradation: As the substance is inorganic, biodegradation is not applicable and a study on ready biodegradation in water does not need to be conducted. However, as the substance is hydrolytically unstable with a half-life < 1h at pH 1.2, 4, 7 and 9 the substance is assumed to be rapidly degradable / eliminated very fast from the aquatic environment.

LogKow: As the substance is inorganic a study for the determination of the partition coefficient does not need to be conducted. However, as the substance is hydrolytically unstable with a half-life < 1h at pH 1.2, 4, 7 and 9 it is assumed that the log Kow is not ≥ 4.

In the following aquatic acute toxicity based on RA key data and identified as worst-case values for the classification of the parent compound Vandium-tris-acetylacetonate is listed:

For fish:

LC50(96h) freshwater = 19.8 mg VAA/L (Brachydanio rerio (zebrafish), semi-static, for NaVO3)

LC50 (96h) marine = 83.6 mg VAA/L (Limanda limanda (Dab), flow-through, for NH4VO3)

For aquatic invertebrates:

EC50 (48h) freshwater = 23.9 mg VAA/L (Daphnia magna, static, for NaVO3)

EC50 (48h) marine = 68.4 mg VAA/L (Nereis diversicolor (annelid), semi-static, NaVO3)

For algae:

TT (24h) freshwater = 2.7 mg/L (Scenedesmus quadricauda, for 2,4 -pentanedione)

EC50 (9d) marine = 3.4 mg VAA/L (Dunaliella marina, for NaVO3)

Based on these data it can be concluded that Vanadium-tris-acetylacetonate does not warrant classification as acute or chronic toxic to the environment according to Regulation (EC) No 1272/2008 (CLP Regulation).
