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 soil macroorganisms was considered not scientifically justified.
Key value for chemical safety assessment
Additional information
The performance of a test for toxicity to soil macroorganisms was considered not scientifically justified.
REACH Regulation (EC) No 1907/2006, Annex IX, Sect. 9.4, Col. 2, states as follows:
“9.4.1: These studies need not to be conducted if direct and indirect exposure of the soil compartment is unlikely.”
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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
