EXECUTIVE SUMMARY: The ready biodegradability of Poliol MB 600 was determined in a closed bottle test in accordance with OECD test guideline 301D at a concentration of 2.0 mg/L in mineral medium inoculated with secondary effluent from a treatment plant (1 mL/L). Sodium benzoate was used as reference substance to check the validity of the method. Mineral medium with inoculum (1 mL/L) without test item and Sodium benzoate served as an inoculum blank and mineral medium with inoculum (1 mL/L) and silicon oil was served as test blank. Separate test solutions were maintained in parallel (in duplicate) for test, reference and control samples for observation on day 0, 7, 14, 21, and 28.
During the experiment, the residual concentration of oxygen in test bottles on day 28 was 6.66 mg/L (guideline limit >0.5 mg/L at all times). The percent biodegradation data revealed that Poliol MB 600 was not readily biodegradable. The maximum degradation was 20.32% on day 28. The biological degradation of the test item with time is given in the below table:
The ThOD value for the test and reference item was 2.569 mg O2/mg and 1.666 mg O2/mg, respectively.
Based on the results of this test, the test item was not readily biodegradable and not toxic to microorganisms in the inoculum.
