Description of key information

No data on the toxicity to soil organisms is available.

Key value for chemical safety assessment

Additional information

Data on the toxicity of the test substance to soil macroorganisms and to terrestrial plants are available. These data substantiate that there were no toxic effects on the tested organisms in the highest concentrations of 1000 mg/kg dry weight of soil nominal (CIBA-GEIGY No.904065 and 904066, 1990c and d). The acute aquatic toxicity assessment covering all trophic levels and two long term studies on daphnids and fish reveal neither a need to classify the substance as dangerous for the environment, nor is it a PBT or vPvB substance. Based on these data it is concluded that the risk to terrestrial organisms is expected to be low.

Additionally, as a pigment in plastic products and car paint, the substance will be included into a matrix without any further environmental release. That means that any introduction into the compartments soil and water is very unlikely. In Annex I of Regulation (EC) No 1907/2006 it is laid down that studies on the effects on terrestrial organisms do not need to be conducted if direct and indirect exposure of the soil compartment is unlikely.

Therefore, toxicity studies on soil microorganisms are not provided.
