Description of key information

Biodegradation in water

Estimation Programs Interface Suite was run to predict the biodegradation potential of the test compound Reaction mass of Benzenamine, N,N-dimethyl- , molybdate, tungstate & phosphates in the presence of mixed populations of environmental microorganisms. The biodegradability of the substance was calculated using seven different models such as Linear Model, Non-Linear Model, Ultimate Biodegradation Timeframe, Primary Biodegradation Timeframe, MITI Linear Model, MITI Non-Linear Model and Anaerobic Model (called as Biowin 1-7, respectively) of the BIOWIN v4.10 software. The results indicate that chemical Benzenamine, N,N-dimethyl-, oxidized, molybdatetungstatephosphates is expected to be not readily biodegradable.

Biodegradation in water

Predicted data for the target compound Reaction mass of Benzenamine, N,N-dimethyl- , molybdate, tungstate & phosphates and various supporting weight of evidence studies for its structurally and functionally similar read across substance were reviewed for the biodegradation end point which are summarized as below:

 

In a prediction done using the Estimation Programs Interface Suite was run to predict the biodegradation potential of the test compound Reaction mass of Benzenamine, N,N-dimethyl- , molybdate, tungstate & phosphates in the presence of mixed populations of environmental microorganisms. The biodegradability of the substance was calculated using seven different models such as Linear Model, Non-Linear Model, Ultimate Biodegradation Timeframe, Primary Biodegradation Timeframe, MITI Linear Model, MITI Non-Linear Model and Anaerobic Model (called as Biowin 1-7, respectively) of the BIOWIN v4.10 software. The results indicate that chemical Reaction mass of Benzenamine, N,N-dimethyl- , molybdate, tungstate & phosphates is expected to be not readily biodegradable.

 

In a supporting weight of evidence study from authoritative database (2018),biodegradation experiment was conducted for 28 days for evaluating the percentage biodegradability of test substance. The study was performed according to OECD Guideline 301 C (Ready Biodegradability: Modified MITI Test (I). 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 substance was determined to be 1 and 0% by BOD, TOC removal and HPLC parameter in 28 days. Thus, based on percentage degradation, test chemical is considered to be not readily biodegradable in nature.

 

For the test chemical,Biodegradation study was conducted for 28 days for evaluating the percentage biodegradability of test substance (authoritative database, 2018). 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 substance was determined to be 0 and 1% by BOD and TOC removal parameter in 28 days. Thus, based on percentage degradation, test chemical is considered to be not readily biodegradable in nature.

 

Another biodegradation study was conducted for 28 days for evaluating the percentage biodegradability of test substance (secondary source, 2017). 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. Initial test substance conc. used in the study was 100 mg/l. The percentage degradation of test substance was determined to be 0% by O2 consumption parameter in 28 days. Thus, based on percentage degradation, test chemical is considered to be not readily biodegradable in nature.

 

On the basis of above results for target chemical Reaction mass of Benzenamine, N,N-dimethyl- , molybdate, tungstate & phosphates (from modelling database, 2018), it can be concluded that the test substance Reaction mass of Benzenamine, N,N-dimethyl- , molybdate, tungstate & phosphates can be expected to be not readily biodegradable in nature.
