Description of key information
Additional information
A number of studies for the test compound 2 Phenylpropionaldehyde(CAS No. 93-53-8) alongwith its predicted data andread across substance studies were reviewed for the biodegradation end point which are summarized as below:
Estimation Programs Interface Suite (EPI suite) was run to predict the biodegradation potential of the test compound 2 Phenylpropionaldehyde(CAS No. 93-53-8). The screening test inherent to the biodegradability of the substance was calculated using the software BIOWIN v4.10. The results indicate 2 Phenylpropionaldehyde was estimated to be readily biodegradable in water.
Biodegradation of alpha-methylbenzyl alcohol was studied (HSDB (U. S. National Library of Medicine), 2016)and it was determined as alpha-methylbenzyl alcohol was completely biodegraded under aerobic conditions within 2-3 weeks. Thus, the test chemical was considered to be readily biodegradable.
In screening tests (HSDB (U. S. National Library of Medicine), 2016), alpha-methylbenzyl alcohol was 50 % degraded as half-life of 7 days was measured under anaerobic conditions. Therefore, after experiment it was observed that alpha-methylbenzyl alcohol (CAS no. 98 -85 -1) was readily biodegradable.
In biodegradation test (HSDB (U. S. National Library of Medicine), 2016), experiment was performed using alpha-methylbenzyl alcohol under aerobic condition at an initial concentration of test substance 6000ppm using BOD parameter for 8 -10 days. Therefore, after experiment alpha-methylbenzyl alcohol (CAS no. 98-85-1) was determined to be readily biodegradable in nature as the chemical was degraded (percentage degradation - 78.2%) in aerobic condition within 8-10 days.
Biodegradation study of test substance alpha-methylbenzyl alcohol (CAS no. 98-85-1) (HSDB (U. S. National Library of Medicine), 2016)was conducted for a period of 32 days using a mixed microbial culture as a test organism.Initial test substance conc. used in the study was 550 mg/l. The percentage degradation of test substance was found to be 96.32% by BOD. Thus, the substancealpha-methylbenzyl alcohol was considered to be readily biodegradable in water.
Biodegradation screening test (J-CHECK) was conducted for 14 days (2 weeks) for evaluating the percentage biodegradability of the test substance. Concentration of inoculum i.e, sludge is 30 mg/l and initial test substance conc. used in the study is 100 mg/l. The percentage degradation of test substance was found to be 33% by BOD. Thus, the substance isopropylbenzene was considered to be readily biodegradable in water.
