Description of key information
Additional information
Biodegradation in water: screening tests
1,1'-(1,1,2,2-tetramethylethylene)dibenzene was assessed in a closed bottle test in accordance to OECD guideline 301 D and EU method C.4 VI. The test item was exposed to activated sludge from an aeration tank for 28 days. Under the test conditions the percentage biodegradation of the material reached a mean of 0.2 % based on ThODNH4. Thus, the test item has to be considered as not ready biodegradable.
Biodegradation in water and sediment: simulation tests
Studies according to OECD 308 and 309 have been requested in decision CCH-D-2114543301-63-01/F and work on them is currently ongoing. The endpoint will be updated with the new information by the set deadline in the final decision.
Biodegradation in soil
A study according to OECD 307 has been requested in decision CCH-D-2114543301-63-01/F and work on it is currently ongoing. The endpoint will be updated with the new information by the set deadline in the final decision.
