Description of key information

Biodegradation in water

Estimation Programs Interface Suite was run to predict the biodegradation potential of the test chemical 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  is expected to be not readily biodegradable.

Predicted data for the test chemical 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 chemical 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  is expected to be not readily biodegradable.

 

In a supporting weight of evidence study from peer reviewed journal (2017), biodegradation experiment was conducted for evaluating the percentage biodegradability of test substance. The study was performed according to OECD Guideline 310 (Ready Biodegradability - CO2 in Sealed Vessels (Headspace Test) under aerobic conditions. Initial test substance conc. used in the study was 20 mg/l, respectively. The percentage degradation of test substance was determined to be -2 and 5.1% by CO2 evolution parameter in 28 and 100 days, respectively. Thus, based on percentage degradation, test chemical is considered to be not readily biodegradable in nature.

 

In another study from peer reviewd journalThe Science of the Total Environment (1981)in this study thePersistence of the test chemical was determined in groundwater at Netherlands and Noordwijk. The half lif of test chemical was estimated from analytical data of number of sampling point downstream of solid waste tip of Noordwijk. The estimated half-life value of test chemical in groundwater at Netherlands and Noordwijk was determined to be 109.5 and 219 days, respectively. Thus, based on this, test substance is considered as persistent in water and can be evaluated to be not readily biodegradable in nature.

 

On the basis of above results for test chemical it is concluded that the test chemical is expected to be not readily biodegradable in nature.
