C12-16 ADBAC was 64% biodegraded in loam soil within 70 days. The DT50 is estimated to be 40 days.
biodegradation of C12-16 ADBAC was evaluated in a loamy soil. There were
two treatments i.e., test substance and chemical blank control, with
three replicates. The test was carried out in biometers containing
approximately 50 g dry weight equivalents of soil to which the test
substance was added in appropriate amounts of deionised water not
exceeding that required for bringing the soils to 50 to 70% of the
maximum moisture capacity. Loam was added to the Erlenmeyers of the
biometer after the test solutions to facilitate moistening of the soils
uniformly by capillary action. Test substance was added at a
concentration of 10 mg carbon per 50 g soil. The side tube contained 20
mL 0.2 M KOH for absorbing carbon dioxide produced by the microorganisms
in the Erlenmeyer. The test was incubated at 22 ± 3°C for approximately
90 days. Biodegradation was calculated as the ratio of experimental to
theoretical carbon dioxide production [ThCO2P]. C12-16 ADBAC
was 64% biodegraded at Day 70. This percentage of the theoretical carbon
dioxide production presumes complete mineralisation. The DT50 was
estimated at 40 days (van Ginkel CG and Pomper MA, 1994).
