- Conclusions:
- Based on mortality of fishes due to the exposure of chemical Aluminium, 6-hydroxy-5-[(4-sulfophenyl)azo]-2-naphthalenesulfonic acid complex at nominal concentration 100 mg/l, experimental median lethal Concentrations [LC-50 (96 h)] on Zebra fish(Danio rerio)was determine to be > 100 mg/l.
- Executive summary:
Fish Acute Toxicity test according to OECD Guideline 203 was conducted for (test item name) aluminium, 6-hydroxy-5-[(4-sulfophenyl)azo]-2-naphthalenesulfonic acid complex.
The test substance was soluble in water. Therefore, the test solution was prepared by dissolving 400 mg of the test substance in 4 liters of potable water (passed through reverse osmosis system) with 2 hrs continuous stirring for achieving test concentrations of 100mg/L,respectively.
The test was performed on the limit concentration i.e nominal concentration selected for the experiment were 100 mg/L and test fish were exposed to these concentration for 96 hours. After 96hrs of exposure LC0, LC50 and LC100 was observed. Effect on the symptoms and the normal activity was checked in the interval of 24rs. pH, tempterature and dissolved oxygen was also checked.
The lethal concentrations LC50 was determine to be >100 mg/L
LC0 (96 hours) (highest loading at which no mortality was observed) = 100 mg/L
LC50 (96 hours) Experimental = >100 mg/L
LC100 (96 hours) (lowest loading at which 100% mortality was observed) =No mortality was observed
Thus based on the LC50 it can be concluded that the chemical aluminium, 6-hydroxy-5-[(4-sulfophenyl)azo]-2-naphthalenesulfonic acid complex was nontoxic and can be consider to be not classified as per the CLP classification criteria.

Additional information
Based on the various experimental data for the target chemical and experimental data for read across chemicals study have been reviewed to determine the toxic nature of target chemical aluminium, 6-hydroxy-5-[(4-sulfophenyl)azo]-2-naphthalenesulfonic acid complex (15790-07-5) on the fishes. The studies are as mentioned below:
In the first key study for the target chemical (15790 -07 -5) from UERL report. Fish Acute Toxicity test according to OECD Guideline 203 was conducted for (test item name) aluminium, 6-hydroxy-5-[(4-sulfophenyl)azo]-2-naphthalenesulfonic acid complex. The test substance was soluble in water. Therefore, the test solution was prepared by dissolving 400 mg of the test substance in 4 liters of potable water (passed through reverse osmosis system) with 2 hrs continuous stirring for achieving test concentrations of 100mg/L,respectively.
The test was performed on the limit concentration i.e nominal concentration selected for the experiment were 100 mg/L and test fish were exposed to these concentration for 96 hours. After 96hrs of exposure LC0, LC50 and LC100 was observed. Effect on the symptoms and the normal activity was checked in the interval of 24rs. pH, tempterature and dissolved oxygen was also checked. The lethal concentrations LC50 was determine to be >100 mg/L
LC0 (96 hours) (highest loading at which no mortality was observed) = 100 mg/L
LC50 (96 hours) Experimental = >100 mg/L
LC100 (96 hours) (lowest loading at which 100% mortality was observed) =No mortality was observed
Thus based on the LC50 it can be concluded that the chemical aluminium, 6-hydroxy-5-[(4-sulfophenyl)azo]-2-naphthalenesulfonic acid complex was nontoxic and can be consider to be not classified as per the CLP classification criteria.
Similarly in the second supporting study for the read across chemical toxicity was studied from the UERL lab, 2017. Fish Acute Toxicity test according to OECD Guideline 203 was conducted for (test item name) aluminium 6-hydroxy-5-[(2-methoxy-5-methyl-4-sulfophenyl)azo]-2-naphthalenesulfonic acid complex. The stock solution prepared as 400mg/4L, with the concentration of 100mg/L, and was kept for 24 hr stirring. After this filter the stock, give it for analytical detection and then stock taken for experiment. The test was performed on the limit concentration i.e nominal concentration selected for the experiment were 100 mg/L and test fish were exposed to these concentration for 96 hours. After 96hrs of exposure LC0, LC50 and LC100 was observed. Effect on the symptoms and the normal activity was checked in the interval of 24rs. pH, tempterature and dissolved oxygen was also checked. The lethal concentrations LC50 was determine to be >100 mg/L
LC0 (96 hours) (highest loading at which no mortality was observed) = 100 mg/L
LC50 (96 hours) Experimental = >100 mg/L
LC100 (96 hours) (lowest loading at which 100% mortality was observed) =No mortality was observed
Thus based on the LC50 it can be concluded that the chemical aluminium 6-hydroxy-5-[(2-methoxy-5-methyl-4-sulfophenyl)azo]-2-naphthalenesulfonic acid complex was nontoxic and can be consider to be not classified as per the CLP classification criteria.
Based on the data from various data, it can be concluded that the substance aluminium, 6-hydroxy-5-[(4-sulfophenyl)azo]-2-naphthalenesulfonic acid complex (15790-07-5) is considered to be not toxic to aquatic environment (fishes) and cannot be classified as toxic as per the criteria mentioned in CLP regulation.
