The ready biodegradation of MTBAC under the conditions of the carbon dioxide (CO2) evolution test (modified Sturm test) was investigated according to OECD guideline 301B and GLP principles. No significant biodegradation of MTBAC was observed. Therefore it is concluded that the substance was not readily biodegradable under the conditions of the modified Sturm test presently performed.
single test concentration of 18mg/L (12 mg TOC/L) was tested during 28
8% biodegradation of MTBAC was observed after 28d.
the toxicity control more than 25% biodegradation of the reference
substance occurred within 14 days (40%, based on ThCO2) indicating that
the test substance does not inhibit microbial activity at a nominal
concentration of 18 mg/L.
study is considered to be reliable without restrictions.
