Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Sediment toxicity

Description of key information
Up to the limit of water solubility, no effects on sediment organisms are to be expected.
Key value for chemical safety assessment
Additional information
No data for sediment toxicity are available for the target substance Aluminium silicate and titanium oxide matrix doted with vanadium, nickel, and antimony.
Generally Aluminium silicate and titanium oxide matrix doted with vanadium, nickel, and antimony is an inert, inorganic substance, which is insoluble in water. If released to the environment, it is to be expected, that the substance sediments and the aluminium silicate matrix combines indistinguishably with the sediment matter. The metals incorporated in the aluminium silicate matrix will not be removed. This was already described in the study for water solubility and will be further confirmed by the transformation/dissolution test, which is in preparation.
Furthermore, data from the analogue approach source substance Zeolite, cuboidal, crystalline, synthetic, non-fibrous catalysts were applied, which confirmed for the above given statement.
The chronic toxicity of Zeolite, cuboidal, crystalline, synthetic, non-fibrous on Paratanytarsus parthenogenetica (Chironomidae) was investigated by Maki and Macek (1978). Test duration was two full life-cycles after which effects of the test substance on emergence, larval growth and egg production was determined. The effects on adult emergence are not interpreted as toxic effects, but rather are related to the physical properties of the test material as they settled to the bottom of the test chamber. So a NOEC value of > 200 mg/L could be stated.
Additional data for long-term toxicity to fish with further analogue approach source substances are not available.
The respective references for the source substance data can be found in the data matrix of the justification for the analogue approach, which can be found either in the CSR or as attachment in Iuclid section 13.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
