Description of key information

With high probability acutely not harmful to soil macroorganisms.
NOEC (14d) >= 1000 mg/kg soil dw (nominal) for Eisenia fetida (OECD 207)

Key value for chemical safety assessment

Additional information

For two ‘red disazo condensation pigments’(CAS 68516-75-6 and CAS 71566-54-6) the acute toxicity on earthworms (Eisenia fetida) was investigated in GLP guideline studies according to OECD 207 [DR.U.NOACK-LABORATORIEN, 2012; ECT Oekotoxikologie GmbH, 2012]. Both tests are conducted as limit tests with a concentration of 1000 mg/kg soil dw. After 14 days of exposure no toxic effects on the earthworms were observed.
