Biodegradation in water: screening tests

Description of key information
In a ready biodegradation study performed according to OECD Guideline 310 and GLP, Terpineol multi, of which alpha-Terpineol is the main constituent, was tested at concentrations of 25.7 mg/L and the inoculum was activated sewage sludge, domestic. The degradation of the test material was assessed by the determination of the inorganic carbon concentration. The test treatments, inoculum blank and reference (sodium acetate) were measured in triplicates. At 25.7 mg/L test concentration, greater than 10% biodegradation of the test substance was reached on Day 5 and greater than 60% biodegradation was reached on Day 12. Hence, the test material met the 10 day window requirement for ready biodegradability. On Days 28, the biodegradation was 80%. The reference material, sodium acetate, reached greater than 60% biodegradation on Day 7. Terpineol multi was considered to be non-toxic to micro-organisms as inhibition of the endogenous respiration of the inoculum was not detected during the test. Hence, it met the validity criteria for reference material and toxicity control. The mean amount of inorganic carbon concentration in the blank control at the end of the test was greater than 3 mg C/L.
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
The test information of Terpineol multi can be used for alpha-Terpineol because Terpineol multi mainly consists of alpha-Terpineol. In addition all constituents of Terpineol multi are expected to have a similar biodegradation potential due to the similarity in structure (see for details on the chemical structures toxico-kinetic section). Therefore alpha-Terpineol is also considered to be readily biodegradable.
