- Conclusions:
- The predicted data from QSAR model suggests the lethal concentration (LC50) for the 5-amino-2-anilinobenzenesulfonic acid was estimated to be 195.985412598 mg/L on fish Danio rerio on the basis of mortality effect.
- Executive summary:
The predicted data from QSAR model suggests the lethal concentration (LC50) for the 5-amino-2-anilinobenzenesulfonic acid was estimated to be 195.985412598 mg/L on fish Danio rerio on the basis of mortality effect in static freshwater condition.
Thus, based on this value, it can be concluded that the target substance 5-amino-2-anilinobenzenesulfonic acid can be considered as non-toxic to aquatic organisms and thus cannot be further consider for aquatic classification as per the CLP criteria.

Additional information
Predicted model data and experimental study results of short term fish for the target chemical 5-amino-2-anilinobenzenesulfonic acid (CAS No. 91-30-5) with respective read across were reviewed to summarize the following information:
In key study the 96 hrs aquatic toxicity study was predicted to assess toxic effects of the test compound 5-amino-2-anilinobenzenesulfonic acid (CAS no. 91-30-5) and the result were predicted (SSS QSAR Prediction model, 2016). The study was based on the effects of the test compound on Danio rerio fish in a static fresh water system. The predicted data suggests the lethal concentration (LC50) for the test compound was estimated to be 195.985412598 mg/l on the basis of mortality effect.
Above predicted lethal concentrations supported by experimental study (Sustainability Support Services (Europe) AB- UERL laboratory; 2016) for read across chemical disodium 5-amino-4-hydroxy-3-(phenylazo)naphthalene-2,7-disulphonate (Cas no. 3567-66-6) which is indicates Fish Acute Toxicity test according to OECD Guideline 203 was conducted for chemical disodium 5-amino-4-hydroxy-3-(phenylazo)naphthalene-2,7-disulphonate on fish species Danio rerio in static fresh water condition. The nominal concentration of selected for the experiment were 100 mg/l and Zebra fish were exposed to these concentration for 96 hours. The lethal concentrations LC50 was found to be >100 mg/L.
Authorative database Data bank of Environmental Properties of Chemicals (EnviChem), 2016 for various read across substance showed following results:
For read across Sodium 4-aminonaphthalene-1-sulphonate (Cas no130-13-2) indicate the Fish toxicity study was conducted for 48 hrs for evaluating the lethal concentration of test substance Sodium 4-aminonaphthalene-1-sulphonate on fish Oryzias latipes on the basis of mortality effect.During experiment the lethal concentration (LC50) for test substance Sodium 4-aminonaphthalene-1-sulphonate was found to be >4000 mg/l.
Read across chemical 7-Amino-4 hydroxy- 2 – naphthalenesulphonic acid (Cas no. 87-02-5) indicate that the Fish toxicity study was conducted for 48 hrs for evaluating the lethal concentration of test substance 7-Amino-4 hydroxy- 2 – naphthalenesulphonic acid on fish Oryzias latipes on the basis of mortality effect.During experiment the lethal concentration (LC50) for test substance 7-Amino-4 hydroxy- 2 – naphthalenesulphonic acid was found to be 480 mg/l.
And read across substance 2-Amino-8-naphthol-6-sulfonic acid (Cas no.90-51-7) indicate Fish toxicity study was conducted for 48 hrs for evaluating the lethal concentration of test substance 2-Amino-8-naphthol6-sulfonic acid on fish Oryzias latipes on the basis of mortality effect.During experiment the lethal concentration (LC50) for test substance 2-Amino-8-naphthol6-sulfonic acid was found to be 335 mg/l.
The above experimental results, are further supported by one more read across 6-aminonaphthalene-1,3-disulphonic acid (Cas no. 118-33-2) which indicates that toxic effects of the substance 6 amino-1,3 naphthalene –disulfonic acid were determined on various fish species such as Leuciscus idus, Brachydanio rerio,Salmo gaidneri, Pimephales promelas, Lepomis macrochirus, Poecilia reticulate for 96 hrs in static condition and in freshwater. During experiment the lethal concentration (LC0) value was found to be 1000 mg/l. (Chemosphere. Vol. 28, No. 12, pp. 2203.2236, 1994)
Thus, based on above lethal concentration values, it can be concluded that the target chemical 5-amino-2-anilinobenzenesulfonic acid (CAS No. 91-30-5) can be considered as non-toxic to fish and thus cannot be classified as hazardous as per the CLP criteria.
