One key study has been identified as having assessed the biodegradation in water screening test. This study followed OECD 301D guideline and was performed to GLP standards: evidence of inherent biodegradability (50% degradation after 28 days) was obtained.A supporting study is also available: BOD/COD ratio was measured over 5-35 days, using acclimated and on-acclimated microbial inocula. Progressive degradation reaching 79-83% (sewage sludge inocula) or 38.6% (commerical Polyseed inoculum) after 35 days was reported, supportimng inherent biodegradability. However degradation rates were not sufficient to meet specific ECHA criteria for inherent biodegradability.
Under aerobic conditions, 1.5mg/l of test material was added to
non-adapted sewage sludge waste for a period of 28 days in a Closed
Bottle test: this resulted in 50% degradation over a 28 exposure period.
A supporting investigation of BOD/COD ratios also found significant
biodegradation (maximally 38.6 -82.9% after 35 days). Accordingly
tertiary butyl acetate is considered to be inherently biodegradable, not
meeting specific ECHA criteria.
