Additional information

Several studies are available in order to assess the toxicity of the substance to microorganisms. The full report is reported only for the reliable key study.

Many data with lower reliability are available for the test substance and are here summarized in the supporting study. Many reports not completed of all information required in order to fulfil a IUCLID study record were found in the archives of the companies: sometimes are old studies, which did not follow a recognized testing method; in some cases details on procedures, test conditions and results are not available; in other cases the procedures are in accordance with the international accepted testing procedures, but only a summary of the results is available.

All of those studies demonstrate that the substance do not inhibit the degradation activity of activated sludge in concentrations higher or equal to 100 mg/l.
