Description of key information
Biodegradation in water:
Biodegradability of test chemical 4,4'-[vinylenebis[(3-sulpho-4,1-phenylene)imino(6-chloro-1,3,5-triazine-4,2-diyl)imino]]bis[5-hydroxy-6-[(1-sulpho-2-naphthyl)azo]naphthalene-2,7-disulphonic] acid (CAS no. 94022-69-2) was estimated by using OECD QSAR tool box v3.4 by considering seven closest read across chemical log Kow as primary descriptor. Percent biodegradation of the test chemical 4,4'-[vinylenebis[(3-sulpho-4,1-phenylene)imino(6-chloro-1,3,5-triazine-4,2-diyl)imino]]bis[5-hydroxy-6-[(1-sulpho-2-naphthyl)azo]naphthalene-2,7-disulphonic] acid was estimated to be 4.15 % by considering BOD as parameter and Microorganism as inoculum in 28 days. On the basis of percent degradability value it can be concluded that test chemical 4,4'-[vinylenebis[(3-sulpho-4,1-phenylene)imino(6-chloro-1,3,5-triazine-4,2-diyl)imino]]bis[5-hydroxy-6-[(1-sulpho-2-naphthyl)azo]naphthalene-2,7-disulphonic] acid is not readily biodegradable.

Biodegradation in water:
Predicted data study for target chemical 4,4'-[vinylenebis[(3-sulpho-4,1-phenylene)imino(6-chloro-1,3,5-triazine-4,2-diyl)imino]]bis[5-hydroxy-6-[(1-sulpho-2-naphthyl)azo]naphthalene-2,7-disulphonic] acid (CAS no. 94022-69-2) and experimental studies for its structurally similar read across chemicals have been conducted and their results are summarized below for biodegradation in water endpoint.
In a predicted data study the Biodegradability of test chemical 4,4'-[vinylenebis[(3-sulpho-4,1-phenylene)imino(6-chloro-1,3,5-triazine-4,2-diyl)imino]]bis[5-hydroxy-6-[(1-sulpho-2-naphthyl)azo]naphthalene-2,7-disulphonic] acid (CAS no. 94022-69-2) was estimated by using OECD QSAR tool box v3.4 by considering seven closest read across chemical log Kow as primary descriptor. Percent biodegradation of the test chemical 4,4'-[vinylenebis[(3-sulpho-4,1-phenylene)imino(6-chloro-1,3,5-triazine-4,2-diyl)imino]]bis[5-hydroxy-6-[(1-sulpho-2-naphthyl)azo]naphthalene-2,7-disulphonic] acid was estimated to be 4.15 % by considering BOD as parameter and Microorganism as inoculum in 28 days. On the basis of percent degradability value it can be concluded that test chemical 4,4'-[vinylenebis[(3-sulpho-4,1-phenylene)imino(6-chloro-1,3,5-triazine-4,2-diyl)imino]]bis[5-hydroxy-6-[(1-sulpho-2-naphthyl)azo]naphthalene-2,7-disulphonic] acid is not readily biodegradable.
Another study was experimental study done from Chemosphere journal Vo1.15 (1986) for structurally similar read across chemical Disodium 4,4'-bis(2-hydroxynaphthalen-1-ylazo)biphenyl-2,6'-disulphonate (CAS no.10169 -02 -5) in this study the aerobic biodegradation experiment was performed for read across chemical Disodium 4,4'-bis(2-hydroxynaphthalen-1-ylazo)biphenyl-2,6'-disulphonate (CAS no.10169 -02 -5) using activated sludge at concentration 0.5 g/L dry material as inoculums and initial concentration of chemical taken was 100mg/L for 42 days. By considering DOC removal parameter read across chemical showed 17% degradation in 42 days. The read across chemical Disodium 4,4'-bis(2-hydroxynaphthalen-1-ylazo)biphenyl-2,6'-disulphonate belongs to D category according to table 1 and 2 as its limit value falls in that range. This percentage value is very less So it is concluded that Disodium 4,4'-bis(2-hydroxynaphthalen-1-ylazo)biphenyl-2,6'-disulphonate (CAS no. 10169 -02 -5) is not readily biodegradable.
Similarly, one more experimental study was done from same source as mentioned in above experimental study for another read across chemical Trisodium 4-hydroxy-4-(4-anilino-5-sulphonato-1-naphthylazo)naphthalene-2,7-disulphonate (CAS no.3861-73-2) in this study the aerobic biodegradation experiment was performed for read across chemical Trisodium 4-hydroxy-4-(4-anilino-5-sulphonato-1-naphthylazo)naphthalene-2,7-disulphonate (CAS no.3861-73-2) using activated sludge at concentration 0.5 g/L dry material as inoculums and initial concentration of chemical taken was 100mg/L for 42 days. By considering DOC removal parameter read across chemical showed 10% degradation in 42 days. The read across chemical Trisodium 4-hydroxy-4-(4-anilino-5-sulphonato-1-naphthylazo)naphthalene-2,7-disulphonate belongs to D category according to table 1 and 2 as its limit value falls in that range. This percentage value is very less So it is concluded that Trisodium 4-hydroxy-4-(4-anilino-5-sulphonato-1-naphthylazo)naphthalene-2,7-disulphonate (CAS no. 3861-73-2) is not readily biodegradable.
On the basis of results of all the studies mentioned above for target chemical 4,4'-[vinylenebis[(3-sulpho-4,1-phenylene)imino(6-chloro-1,3,5-triazine-4,2-diyl)imino]]bis[5-hydroxy-6-[(1-sulpho-2-naphthyl)azo]naphthalene-2,7-disulphonic] acid (CAS no. 94022-69-2) as well as for its structurally similar read across chemicals it can be concluded that test chemical is not readily biodegradable.
