Additional information

The influence of the Similar substance 01 on the respiration rate of activated sludge was investigated after a contact time of 30 minutes, based on OECD Guideline No. 209, adopted April 4, 1984 and EEC Directive 67/548 amended November 18, 1987 (87/302), Part C, Publication No. L133, adopted May 30, 1988.
