Additional information
Based on the various prediction data for the target chemical and experimental data for read across chemical which was structurally and functionally similar with the target chemical, study have been reviewed to determine the toxic nature of Ethylbenzenesulphonic acid (57352-34-8) on the growth of fish. The studies are as mentioned below:
In the first predicted study for the target chemical Ethylbenzenesulphonic acid (57352-34-8) from QSAR toolbox 2017, study was carried out. Based on the prediction done using the OECD QSAR toolbox version 3.3 with log kow as the primary descriptor and considering the five closest read across substances, toxicity on Danio rerio (previous name: Brachydanio rerio) was predicted for Ethylbenzenesulphonic acid ( 2-ethylbenzenesulfonic acid) (57352-34-8). Based on the mortality of test organism the LC50 value was estimated to be 110.224 mg/l when Ethylbenzenesulphonic acid exposed to Danio rerio for 96 hrs. Based on this value it can be concluded that the substance Ethylbenzenesulphonic acid is considered to be not toxic to aquatic environment as per the criteria mentioned in CLP regulation.
Second weight of evidence study conducted for the read across RA chemical (98-33-9) from Sewage Ind. Wastes, 1957, which is structurally and functionally similar with the target chemical. In acute toxicity to fish test been performed to evaluate the toxicological effects of chemical 3 - methylsulphanilic acidin fish. The chemical was exposed to Gambusia affinis fish with dose concentration of 180, 320, 560, 1000 mg/L with exposure duration of 24, 48 and 96 hrs. Adult mosquitofish fishes were collected from Stillwater creek from payne country. Test performed in the static system under the proper temperature and pH. 10 fishes in 1 aquarium used for the test. After the incubation lethal effect was measured at which 50% growth inhibited. In control at 180 mg/l and less, the fishes were apparently normal. At 320 ppm one was dead in 48-hrs, 2 in 72-h and fourth in 96-h. At 560 and 1000 ppm all were dead in 6 hrs. Only. Based on the mortality of Gambusia affinis fish due to the contact with chemical 3 - methylsulphanilic acid, the LC50 was determine to be 425 mg/l, 410, 375 mg/l for 24, 48, 96hrs. Based on the LC50, it can be concluded that the chemical 3 - methylsulphanilic acid was nontoxic and be consider to be not classified as per the CLP classification criteria.
Similarly in the third weight of evidence study for the read across chemical (121-57-3) Chemophere, 1994. Toxic effects of test substance 4-amino-benzenesulfonic acid was determined on various fish species like Leuciscus idus, Brachydanio rerio, Salmo gaidneri, Pimephales promelas, Lepomis macrochirus, Poecilia reticulate for 48 and 96 hrs in static condition and in fresh water. Based on the experimental data the lethal concentration i.e LC0 and LC50 of test substance 4-amino-benzenesulfonic acid on fish Leuciscus idus, Brachydanio rerio, Salmo gaidneri, Pimephales promelas, Lepomis macrochirus, Poecilia reticulate was determine to be LC50 was 100.4 mg/l for 96 hrs and LC0 was 1000 mg/l for 48 hrs. Thus based on the above experimental result the test substance 4-amino-benzenesulfonic acid (Cas no. 121-57-3) was nontoxic to fish and thus not consider for the further classification as per the CLP criteria.
Similarly in the fourth weight of evidence study for the read across chemical (88-44-8) Envichem 2017, in experimental study the toxic effects of test substance 2-amino-5-methylbenzene - sulfonic acid was examined on fish Oryzias latipes for 48 hrs. During experiment the lethal concentration (LC50) was determine to be 480 mg/l on the basis of mortality effects. Thus based on the lethal concentration of substance 2-amino-5-methylbenzenesulfonic acid it can be consider that it is nontoxic to fish and thus not consider for aquatic classification.
Based on the predicted data for the target chemical and experimental studies for the read across chemical obtain from various sources (Sewage Ind. Wastes, 1957, Chemosphere, Envichem, 2017) toxicity on fish was studied due to the exposure of Ethylbenzenesulphonic acid (57352-34-8), it was concluded that the chemical Ethylbenzenesulphonic acid was consider as nontoxic and can be consider to be not classified as toxic to fish as per CLP classification criteria.
