Toxicity of chemical 4,4',4''-Triaminotrityl alcohol on the growth of aquatic life’s have been studied and concluded the nature and classification category on the basis of data obtain from various sources, RA chemicals and also from predicted QSAR reports which support the classification of the target chemical.

In the first weight of evidence study for 4,4',4''-Triaminotrityl alcohol(467-62-9) from QSAR toolbox version 3.4, 2017, Based on the prediction done using the OECD QSAR toolbox version 3.4 with log kow as the primary descriptor and considering the seven closest read across substances, toxicity on Daphnia magna predicted for 4,4',4''-Triaminotrityl alcohol (467-62-9).The EC50 value was estimated to be 225 mg/l when4,4',4''-Triaminotrityl alcohol exposed to Daphnia magna for 48 hrs.

 

Similarly in the another weight of evidence study for 4,4',4''-Triaminotrityl alcohol(467-62-9) from EPI suite 2017, Based on the prediction done by EPI suite, ECOSAR version 1.1, on the basis of similarity of structure to chemicals for which the aquatic toxicity has been previously measured by structure-activity relationships (SARs) program, the LC 50 value for short term toxicity to aquatic invertebrates was predicted. On the basis of this program, the LC 50 value for short term toxicity to aquatic invertebrates was predicted to be 296.457 mg/l for Tris(p-aminophenyl) methanol in 48 hrs. Based on this value it can be concluded that the substance Tris(p-aminophenyl)methanol is considered to be not toxic to aquatic environment and cannot  be classified in aquatic acute 1/chronic 1/chronic 2/chronic 3 category as per the criteria mentioned in CLP regulation.

 

Similarly in the third weight of evidence study for RA chemical (112-11-2), ecotoxicology. Study was conducted to determine the toxicity of chemical Sulfadimethoxine on the mobility of daphnia magna for 48hrs of exposure with chemical. Test was performed according to the U.S. Environmental Protection Agency guideline. Effect concentration of chemical on Freshwater daphnia was tested by static system. Different measured concentration was prepared by dissolving the Sulfadimethoxine with solvent carrier, 0.5% of dimethylsulphoxide (DMSO). Daphnia fed daily during the test. All water parameters measured daily. Immobilization was employed as an endpoint and considered to happen if no movement was detected for 15 s after gentle shaking of the test vehicle. Immobilization measured by probit analysis. Based on the immobilization of daphnia magna due to the exposure of chemical Sulfadimethoxine, the EC50 was 639.8 mg/l with 95 % CI was 396.10-883.5 MG/L for 24hrs exposure and 248 mg/l with 95 % CI was 199.20-296.8 mg/l for 48hrs. Thus it was concluded that the chemical was nontoxic and can be consider to be not classified as toxic to aquatic environment as per the CLP classification criteria.

 

Similarly in the fourth weight of evidence study for RA chemical 2-Amino-9,10-anthracenedion (117-79-3) Study was conducted to determine the toxicity of chemical 2-Amino-9,10-anthracenedion on the mobility of daphnia magna for 24hrs of exposure with chemical. Test was performed in the static system in which <24 h old Daphnis were used. After the exposure, based on the immobilization of daphnia magna due to the exposure of chemical 2-Amino-9,10-anthracenedion (2-amino-9,10-dihydroanthracene -9,10-dione), the EC50 was 278 mg/l after 24hrs exposure with chemical. Thus it was concluded that the chemical was nontoxic and can be consider to be not classified as toxic to aquatic environment as per the CLP classification criteria.

 

 

Thus based on the data available for 4,4',4''-Triaminotrityl alcohol(467-62-9), from various data sources ecotox, EPIsuite, publications and QSAR toolbox version 3.4, 4,4',4''-Triaminotrityl alcoholwas consider to be nontoxic and thus can be consider to be not classified as per the CLP classification criteria.

Toxicity to aquatic algae and cyanobacteria:

Toxicity of chemical 4,4',4''-Triaminotrityl alcohol on the growth of aquatic life’s have been studied and concluded the nature and classification category on the basis of data obtain from various sources, RA chemicals and also from predicted QSAR reports which support the classification of the target chemical.

 

In the first weight of evidence study for 4,4',4''-Triaminotrityl alcohol(467-62-9) from QSAR toolbox version 3.4, 2017, Based on the prediction done using the OECD QSAR toolbox version 3.4 with log kow as the primary descriptor and considering the six closest read across substances, toxicity on Desmodesmus subspicatus (previous name: Scenedesmus subspicatus) predicted for 4,4',4''-Triaminotrityl alcohol (467-62-9).The EC50 value was estimated to be 107.48 mg/l when4,4',4''-Triaminotrityl alcohol (467-62-9)exposed to Desmodesmus subspicatus (previous name: Scenedesmus subspicatus)for 72 hrs.

 

Similarly in the another weight of evidence study for 4,4',4''-Triaminotrityl alcohol(467-62-9) from EPI suite 2017, Based on the prediction done using the EPI Suite ECOSAR version 1.11, the short term toxicity on green algae was predicted for test substance Tris(p-aminophenyl) methanol. On the basis of effects observed in a static freshwater system, the effect concentration EC50 value of the substance is estimated to be191.688 mg/l for green algae for 96 hrs.. Based on this value, it can be concluded that the test chemical Tris(p-aminophenyl)methanol can be considered as non-toxic to green algae at environmentally relevant concentrations and can be considered not-classified as per the CLP classification criteria.

 

 

Similarly in the third weight of evidence study for RA chemical (106-47-8), ecotox databases 2017, Study was conducted to determine the toxicity of chemical 4-Chloroaniline on the growth of daphnia magna. Test was performed in the static system for a very short period (>=49 - <=79) Minute(s). After the exposure no effect was observed on the photosynthesis rate of green algae. Based on the Photosynthesis reduction of green algae (Scenedesmus Subspicatus) due to the exposure of chemical 4-Chloroaniline, the NOEC was 250 mg/l. Thus it was concluded that the chemical was nontoxic and can be consider to be not classified as toxic to aquatic environment as per the CLP classification criteria.

 

Thus based on the data available for toxicity to invertebrates and algae of 4,4',4''-Triaminotrityl alcohol (467-62-9), from various data sources ecotox, EPIsuite, databases publications, and QSAR toolbox version 3.4, 4,4',4''-Triaminotrityl alcohol was consider to be nontoxic and thus can be consider to be not classified as per the CLP classification criteria.
