Additional information
The inhibitory effect of the test item on the respiration rate of aerobic wastewater microorganisms of activated sludge was investigated in a respiration inhibition test according to the OECD Guideline No. 209 and the method C.11 of the EEC-Directive 87/302 No. 133/118. Aerobic activated sludge from a domestic waste-water treatment plant was used in the test. The nominal concentrations tested were in the range from 3.2 to 100 mg/l. In addition, two blank control and five different concentrations of the reference item 3,5-dichlorophenol were tested in parallel.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
