Description of key information

Direct and indirect exposure of the test item 1,1’-(1,1,2,2-tetramethylethylene)dibenzene to soil is highly unlikely. The test substance is practically insoluble in water. In addition, low exposure is guaranteed, as no sludge application from STP on soil will be done and aerial deposition is negligible. Thus, toxicity to terrestrial arthropods was considered scientifically not justified.

Key value for chemical safety assessment

Additional information

The performance of a test for toxicity to terrestrial arthropods is scientifically unjustified.

REACh Regulation (EC) No 1907/2006, Annex IX, Sect. 9.4, Col. 2, states as follows:

“9.4: Effects on terrestrial organisms: These studies do not need to be conducted if direct and indirect exposure of the soil compartment is unlikely.”
