Description of key information
In order to predict effects of chemicals in the environment and in biological wastewater treatment plants, an activated sludge respiration inhibition test was performed on the test substance according to OECD 209 guideline and GLP requirements. The test substance was not soluble in water and therefore the activated sludge was exposed to bis (tert-butyl peroxy isopropyl)benzene adsorbed onto silica gel at a concentration of 1 g/litre. By this exposure no effect was recorded indicating that the obtained distribution of the test substance in the water system did not inhibit the activated sludge. Validity criteria were fulfilled.

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.
