Additional information

A concentration series of test substance from 7.4 to 103 mg/L loading of hydrogenated terphenyl in water (after 6 days stirring at room temperature) was used to prepare a series of WAFs. All WAFs showed the same final dissolved concentration of 25+/-5 µg/L. The WAFs of hydrogenated terphenyl have no adverse effects on the respiration rate of activated sludge: respiration rates in the test conditions were all comparable to the control.
