The toxicity of MV 31 to activated sludge organisms was assessed in an
assay performed according to OECD TG209. The test solution was made by
stirring MV 31 for 24 hours in a closed vessel at a loading rate of 2000
mg/L, with subsequence dilution to 1000 mg/L for the test. No inhibition
was observed upon exposure to MV 31 at the loading rate. The 3-hour EC50
to sludge is therefore >1000 mg/L.
The study was conducted in accord with GLP criteria and satisfies the
guideline requirements for test method OECD209, activated sludge
respiration inhibition test. It is classified as reliable without
restrictions and is suitable for Risk Assessment, Classification &
Labelling, and PBT Analysis.
Test Type: Static
EC50: >1000 mg/L 95% C.I.: not applicable
NOEC: 1000 mg/L Probit Slope: not applicable
Endpoint(s) Effected: Respiration inhibition
