The toxicity of PPVE to activated sludge organisms was assessed in an
assay performed according to OECD TG209. The test solution was made by
adding the volatile test substance under the surface of the test
solution. The exposure period was for three hours with continuous
aeration and stirring. No statistically significant inhibition was
observed upon exposure to PPVE at the maximum loading rate (α = 0.05, df
= 7). 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. However, the test substance is highly
volatile and was tested in an open, aerated system. It is classified as
reliable with restriction, and is suitable for Risk Assessment,
Classification & Labelling, and PBT Analysis.
