Description of key information
Biodegradation in water
On the basis of the experimental studies of the test chemical and applying the weight of evidence approach, the percentage degradation of the test chemical can be expected to be 74, 83, 94 and 100% by O2 consumption, test material analysis, BOD and GC parameter in total 28 days, respectively. Thus, based on this, it can be concluded that the test chemical is readily biodegradable in water.
Additional information
Biodegradation in water
Data available for the test chemical has been reviewed to determine the percentage biodegradation. The studies are as mentioned below:
The percentage degradation of test chemical was determined to be 74% by O2 consumption parameter in 28 days. Thus, based on percentage degradation, test chemical is considered to be readily biodegradable in water.
In an another study, biodegradation experiment was conducted for 28 days for evaluating the percentage biodegradability of test chemical. The study was performed according to Council Directive 92/69/EEC Method C.4-D guidelines. Initial test substance conc. used in the study was 100 mg/l. The percentage degradation of test chemical was determined to be 59, 67, 75 and 83% by Test material analysis parameter in 10, 14, 20 and 28 days, respectively. Thus, based on percentage degradation,test chemical is considered to be readily biodegradable in nature.
Another biodegradation study was conducted for 28 days for evaluating the percentage biodegradability of test chemical. The study was performed according to OECD Guideline 301 C (Ready Biodegradability: Modified MITI Test (I) under aerobic conditions. Activated sludge was used as a test inoculums for the study. Concentration of inoculum i.e, sludge used was 30 mg/l and initial test substance conc. used in the study was 100 mg/l, respectively. The percentage degradation of test chemical was determined to be 94% and 100% by BOD and GC parameter in 28 days. Thus, based on percentage degradation, test chemical is considered to be readily biodegradable in nature.
On the basis of the experimental studies of the test chemical and applying the weight of evidence approach, the percentage degradation of the test chemical can be expected to be 74, 83, 94 and 100% by O2 consumption, test material analysis, BOD and GC parameter in total 28 days, respectively. Thus, based on this, it can be concluded that the test chemical is readily biodegradable in water.
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).
