study was performed to assess the ready biodegradability of the test
item in an aerobic aqueous medium. The method was designed to be
compatible with the OECD Guidelines for Testing
of Chemicals (1992) No. 301D, "Ready Biodegradability; Closed Bottle
test item, at a concentration of 33 mg/L, was exposed to sewage
treatment micro-organisms with mineral medium in sealed culture vessels
in the dark at approximately 21°C for 28 days. The degradation of the
test item was assessed by the determination of the amount of oxygen
consumed. Control solutions with inoculum and the reference item, sodium
benzoate, together with a toxicity control were used for validation
test item attained 6% biodegradation after 28 days and therefore cannot
be considered to be
readily biodegradable under the terms and conditions of OECD Guideline
Ready biodegradability of the Test Substance.
