Additional information
The inherent biodegradability of the test substance FAT 20010/C was determined in a GLP-compliant study in Zahn-Wellens / EMPA Test according to OECD Guideline 302B. The test substance FAT 20010/C and the reference substance Diethylene glycol, respectively, were tested in concentrations of 150 mg/I DOC. The biodegradation of the test substance FAT 20010/C after 28 days was 0 %. Individual BOD5 and COD estimation were done in GLP-compliant studies according to ISO 5815 and EEC 92/69/C.6 (1992), respectively. The biochemical oxygen demand of FAT 20010/C 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 biochemical oxygen demand of FAT 20010/C 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 20010/C was found to be 0 mg O2/g and 1100 mg O2/g, respectively.
Few non-GLP compliant studies performed in the 70’s have reported the following BOD5 and COD values for FAT 20010:
BOD5 = 52 mg/g O2
COD = 554 mg/g O2
BOD5 = 0 mg/g O2
Relevant is the BOD5/COD quotient which is not >0.5, therefore the substance is not indicative of rapid degradation. Taking into consideration the data from key study and supporting studies, the test substance FAT 20010 can be regarded as not biodegradable..
