a 3h activated sludge respiration inhibition study conducted according
to OECD TG 209 and GLP, microorganisms in activated sludge were exposed
in a combined limit/range-finding test to a blank control and 3
concentrations of the test substance at loading rates of 10, 100 and
1000 mg test substance/L.The
substance showed no inhibition of the respiration rate at 10 and 100
mg/L, and 12% inhibition of the respiration rate at 1000 mg/L.Therefore
the EL50 of the test substance was above 1000 mg/L. The NOELR could not
