96 h
Key result
Duration:
96 h
Dose descriptor:
LC50
Effect conc.:
114.09 mg/L
Nominal / measured:
estimated
Conc. based on:
test mat.
Basis for effect:
mortality
Remarks on result:
other: not toxic
Details on results:
Chemical may not be soluble enough to measure this predicted effect. If the effect level exceeds the water solubility by 10X, typically no effects at saturation (NES) are reported.
Conclusions:
On the basis of EPI suite, ECOSAR version 1.1, the LC50 value for short term toxicity to fish was predicted to be 114.09 mg/l for Dialuminium tris[4-hydroxy-3-[(4-sulphonato-1-naphthyl)azo]naphthalenesulphonate] in 96 hrs. Based on the LC50 value, it can be concluded that the substance Dialuminium tris[4-hydroxy-3-[(4-sulphonato-1-naphthyl)azo]naphthalenesulphonate] can be considered as not toxic to aquatic environment and thus “not classified” as per the CLP criteria.
Executive summary:

On the basis of EPI suite, ECOSAR version 1.1, the LC50 value for short term toxicity to fish was predicted to be 114.09 mg/l for Dialuminium tris[4-hydroxy-3-[(4-sulphonato-1-naphthyl)azo]naphthalenesulphonate] in 96 hrs. Based on the LC50 value, it can be concluded that the substance Dialuminium tris[4-hydroxy-3-[(4-sulphonato-1-naphthyl)azo]naphthalenesulphonate] can be considered as not toxic to aquatic environment and thus “not classified” as per the CLP criteria.
