Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

toxicity to bees: acute oral
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
a short-term study does not need to be conducted because an appropriate long-term toxicity study on terrestrial organisms is available
Justification for type of information:
there is a long-term study available (OECD 222)
toxicity to bees: acute contact
Data waiving:
other justification
Justification for data waiving:
toxicity to bees: chronic oral
Data waiving:
exposure considerations
Justification for data waiving:
the study does not need to be conducted because direct and indirect exposure of the soil compartment is unlikely
Justification for type of information:
The substance is not supposed to be directly applied to soil. Based on the PC properties of the substance (extremely low solubility in water and octanol), a low adsorption potential is indicated. Therefore, binding to sewage sludge is unlikely and as a consequence a transfer to the soil compartment is not expected. Therefore it can be assumed that there is no direct and indirect exposure to the environment. Furthermore, due to their physico-chemical properties and very low (bio)solubility the Diazopyrazolone Pigments are considered to be not bioavailable. This is supported by the absence of toxicity in long term experiments with earthworms and sediment worms.

Description of key information

Direct and indirect exposure of the soil compartment is unlikely. In addition, there is no indication for any toxicity of the test substance, neither in tests on earthworms (Eisenia fetida) and sediment worms nor in tests on aquatic organisms of all trophic levels (acute and chronic). Furthermore, the outcome of the CSA indicates that the available terrestrial toxicity tests are appropriate to cover the information requirements. Therefore no further terrestric studies are necessary.
