Biodegradation in water: screening tests
This endpoint is addressed using one key study and three supporting studies.
The key study (Bayer, 2000b) was performed in accordance with the standardised guideline EU Method C.4-E under GLP conditions. Domestic activated sludge (non-adapted) was exposed to an initial concentration of the test material of 3.3 mg/L under aerobic conditions for a period of 28 days. Degradation was followed by analysis of dissolved oxygen.
After 28 days 37 % of the test material was degraded, therefore it is not readily biodegradable.
In the first supporting study (Bayer, 1979, adapted) a closed bottle test comparable to the standardised guideline OECD 301 D was performed. Predominantly domestic sewage (adapted) was exposed to an initial concentration of the test material of 2.4 mg/L under aerobic conditions for a period of 20 days. Degradation was assessed via oxygen consumption.
After 20 days 99.5 % of the test material had been degraded, which indicates a potential of inherent biodegradability of the material.
In the second supporting study (Bayer, 1979, non-adapted) a closed bottle test comparable to the standardised guideline OECD 301 D was performed. Predominantly domestic sewage (non-adapted) was exposed to an initial concentration of the test material of 2.4 mg/L under aerobic conditions for a period of 20 days. Degradation was assessed via oxygen consumption.
After 20 days 48 % of the test material had been degraded.
In the third supporting study (Andreoni et al. 1990) the biodegradability of diphenyl carbonate with enriched mixed cultures was investigated. Adapted activated sludge from a waste water treatment plant was exposed to the test material under aerobic conditions at an initial test material concentration of 833 mg/L.
100 % biodegradation was determined turbidimetrically after 2.7 days. Enriched mixed cultures and the isolated strain Acinetobacter calcoaceticus showed good growth in the presence of diphenyl carbonate. Degradation/hydrolysis was complete after 65 hours.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
