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 microorganisms was considered not scientifically justified.
Key value for chemical safety assessment
Additional information
The performance of a test for toxicity to soil microorganisms was considered scientifically not justified.
REACH Regulation (EC) No 1907/2006, Annex IX, Sect. 9.4, Col. 2, states as follows:
“9.4.2: Effects on terrestrial organisms: These studies do not need to be conducted if direct and indirect exposure of the soil compartment is unlikely.”

Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
