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.

Description of key information

Additional information

Based on the integrated testing strategy (ECHA R.7c, 2017) a stepwise approach to hazard identification on terrestrial organisms is required. Tests of toxicity on earthworm were considered as first step, due to the fact that earthworms are exposed via multiple uptake routes (soil pore water, ingestion of soil material, soil air, secondary poisoning).

For the test substance the acute toxicity on earthworms (Eisenia fetida) was investigated in a GLP guideline studiy according to OECD 207 (BASF, 2013). The test is conducted up to a maximum concentration of 1000 mg/kg soil dw. After 14 days of exposure no toxic effects on the earthworms were observed.

This confirms the results from the aquatic tests where no hazard was identified.

It can be expected that ‘yellow disazo condensation pigments’ are essentially not bioavailable, due to the large molecular size together with the negligible low solubility. Therefore it can be assumed with sufficient confidence, that further tests on terrestrial organisms would not provide any additional information for improving the risk assessment. Hence tests on plants and terrestrial microorganisms are not required.
