Additional information
The inherent biodegradability of the test substance FAT 21021 was determined in a GLP-compliant study in Zahn-Wellens / EMPA Test according to OECD Guideline 302C. The test substance FAT 21021 and the reference substance Sodium benzoate, respectively, were tested in concentrations of 100 mg/I. The biodegradation of the test substance FAT 21021 after 28 days was 0 %. The COD estimation was done in GLP-compliant studies according to ISO 5815 and EEC 92/69/C.6 (1992), respectively. The biochemical oxygen demand of FAT 21021 was determined by measuring the dissolved oxygen concentration before and after 5 days incubation at 20 °C in different test concentrations diluted in water saturated with dissolved oxygen that contains a seed of micro-organisms. In another key study the biochemical oxygen demand of FAT 21021 was determined by measuring the dissolved oxygen concentration before and after 5 days incubation at 20 °C in different test concentrations diluted in water saturated with dissolved oxygen that contains a seed of micro-organisms. The BOD5 and COD of FAT 21021 was found to be 0 mg O2/g and 1358 mg O2/g, respectively. Few non-GLP compliant studies performed in the 70’s have reported the following BOD5 and COD values for FAT 21021:
BOD5 = 130 mg/g O2
COD = 11840 mg/g O2
Relevant is the BOD5/COD quotient which is not >0.5, therefore the substance is not indicative of rapid degradation. Taking the data from key study and supporting studies into account, the test substance FAT 21021 can be regarded as not biodegradable.
