Description of key information

Risk Characterization Ratio (i. e. PEC/PNEC ratio) terrestrial compartment < 1

Key value for chemical safety assessment

Additional information

No experimental data evaluating the toxicity of 4,4´-(9H-fluoren-9-ylidene)bis(2-chloroaniline) (CAS No. 107934-68-9) to soil organisms are available. According to the standard requirements set in Regulation (EC) No. 1907/2006, Annexes VII and VIII, information regarding the effects of the substance on soil organisms does not need to be presented at this tonnage band (10 -100 t/y). Nevertheless, since the substance is classified as toxic for aquatic organisms, an assessment of the potential hazard of 4,4´-(9H-fluoren-9-ylidene)bis(2-chloroaniline) to terrestrial species is performed as well. The environmental exposure assessment performed for this substance (see CSR attached to IUCLID section 13) shows that indeed the Risk Characterization Ratio (i. e. PEC/PNEC ratio) in the soil compartment is < 1 and therefore, under the current exposure conditions, 4,4´-(9H-fluoren-9-ylidene)bis(2-chloroaniline) (CAS No. 107934-68-9) does not pose a risk to terrestrial organisms and further testing is not deemed necessary according to Regulation (EC) No. 1907/2006, Annex XI, section 3.
