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.

Additional information

Data on the toxicity of C.I. Pigment Red 104 to soil macro-organisms are not available. The substance is generally assumed to be not bioavailable to terrestrial organisms due to its low solubility and its stability. As stated in chapter 5.0 Chromate (CrO42-) and lead ions (Pb2+) may dissociate from the substance. Tests on the toxicity of both ions to earthworms indicate that lead and chromium ions are taken up by earthworms. A study conducted by Beyer et al. (1982) demonstrated that lead was taken up by earthworms but was not concentrated by the animals. Comparable results were determined for chromium. At a concentration of 20 mg/l a mortality rate of 50 % was determined after 28 days of exposure (Soni and Abbasi, 1981).
