Additional information
The study was conducted according to the test guideline and all data generated for this study are considered to be valid.
The 3 hour EC50of Laponite Type 1 toactivated sludge respirationinhibition was calculated as greater than 1000mg/l.
The results of the abiotic control flask (test without addition of inocula) indicated that there would be no reduction in oxygen concentration in any of the test vessels up to, and including, 1000mg/l Laponite Type 1, attributable to processes in the test system other than those due to the activity of the activated sludge.
