OECD test 301C: "Ready Biodegradability: Modified MITI Test (I)" (1992)
- 0% degradation after 28 days therefore substance not considered
A study was performed to assess the ready biodegradability of the test
material in an aerobic aqueous media. This study was conducted in
accordance with the Test Method Relating to New Chemical Substances
Biodegradability Test of Chemical Substances by Microorganisms and OECD
Guideline for Testing of Chemicals 301C "Ready Biodegradability:
Modified MITI Test (I)" (1992).
The test substance (100mg/L) was exposed to activated sludge (30mg/L) in
a closed-system oxygen consumption measuring apparatus. The biochemical
oxygen demand (BOD) was measured over a 28-day period. After this
period, the amount of the dissolved organic carbon (DOC) and the
residual amount of the test substance were measured. The
biodegradability of the test substance was evaluated from these results.
The test material attained 0% degradation after 28 days and therefore
cannot be considered to be readily biodegradable under the strict terms
and conditions of OECD Guideline No 301C.
