Additional information
Predicted data for the target compound Butane-1,2,3,4-tetracarboxylic acid (CAS No. 1703 -58 -8) and supporting weight of evidence studies for its read across substance were reviewed for the biodegradation end point which are summarized as below.
Biodegradability of test chemical Butane-1,2,3,4-tetracarboxylic acid is predicted using OECD QSAR tool box v.3.3 using log Kow as primary descriptor. The predicted value for biodegradation is 86 % by BOD parameter in 28 days therefore, it is concluded that this test chemical Butane-1,2,3,4 -tetracarboxylic acid is readily biodegradable.
In a another prediction using the Estimation Programs Interface Suite (EPI suite, 2017) was run to predict the biodegradation potential of the test compound Butane-1,2,3,4- tetracarboxylic acid ( CAS no. 1703 -58 -8) 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 butane-1,2,3,4-tetracarboxylic acid is expected to be readily biodegradable.
In supporting weight of evidence study from seconadry source ( J check) 2017 for read across chemical 1,10 -Decanedioic acid ( CAS no. 111 -20 -6) the experiment was carried out to test biodegradability by taking three parameters into consideration namely BOD, TOC and HPLC. The inoculums used for this experiment was activated sludge at 30mg/Concentration. The initial concentration of read across chemical taken was 100 mg/L.The biodegradability test was carried out for 28 days. The percent biodegradation of read across chemical obtained was 89 % by BOD parameter and 100% by parameter TOC and HPLC. All percentages are high, so it is concluded that read across chemical 1, 10-Decanedioic acid is readily biodegradable.
On the basis of above results of target chemical Butane-1,2,3,4 -tetracarboxylic acid ( From OECD QSAR tool box. v3.3 and EPI suite, 2017 ) and for its read across substance from secondary source it can be concluded that the target chemical Butane-1, 2, 3, 4- tetracarboxylic acid is expected to be readily biodegradable in nature.
