The toxicity to microorganisms of (-)-beta-pinene was determined in a read-across approach.A respiration inhibition study was performed to assess the effect of delta-3-carene on STP microorganisms according to OECD guideline No 209. The 3h-EC50 of delta-3-carene for inhibition of respiration of activated sludge is 326 mg/L.The 3h-EC10 of delta-3-carene for inhibition of respiration of activated sludge is 38 mg/L.Therefore, delta-3-carene is considered harmful to activated sludge.
The toxicity to microorganisms of
(-)-beta-pinene was determined in a read-across approach.
Key study conducted on delta-3 -carene
according to OECD 209 Guideline under GLP without deviation.
Delta-3-carene was tested at nominal
concentrations of 0 (control), 17.3, 34.6, 69.1, 138.2, 276.5, 553 mg/L
and the inoculum (microbial source) was activated sludge of a
predominantly domestic sewage.
