Additional information
Experimental study for the target chemical 2-[2-[4-[(2-chloroethyl)ethylamino]-o-tolyl]vinyl]-1,3,3- trimethyl-3H-indolium chloride (CAS No. 6441-82-3) and various supporting weight of evidence studies for its structurally similar read across substanceswere reviewed to summarize the following information:
In an experiment key study from peer reviewed journal (Vernon C. Applegate et. al; 1957), Short term toxicity test to rainbow trout, bluegill and sea lamprey was carried out for 24 hrs. Test organisms Sea lamprey (Petromyzon marinus), Rainbow trout (Salmo gairdnerii) and Bluegill (Lepomis macrochius) were used for the study. The study was performed under static conditions for 24 hrs. The test chemical2-[2-[4-[(2-chloroethyl)ethylamino]-o-tolyl]vinyl]-1,3,3- trimethyl-3H-indolium chloride (CAS no. 6441-82-3) conc. used for the study was 5 mg/l. Larval lampreys were collected by means of an electric shocker in the Ocqueoc River, Presque Isle County, Michigan, and were held in running water in aquaria and small “races” under conditions which simulated their natural stream habitat.Test fishes (Rainbow trout and Bluegill) were obtained fromthe stocks of local state and Federal fish hatcheriesand were held in large raceways. These specimens were maintained in the best possible physical condition until used in the laboratory.
The aggregate test animals available, usually six in number, were placed together in a 10-literglass battery jar containing 5 liters of water. The jars were provided with aeration through standard stone air-breakersand were maintained at a constant temperature by immersion in specially constructed constant temperature troughs. Water temperature was maintained within the limits of ± 1.0 °F.Twelve of these test jars (each containing a substance being assayed) were included with one control jar in each trough. Fish and larvae in the control jar were exposed only to the water and physical conditions of the typical test container.Test condition contains dissolved oxygen from 8.6 to 13.7 ppm and free CO2from 5.0 to 9.0 ppm. Observations of each test were measured approx. six times, at various intervals, during the 24 hr test period. At each observation, the condition of every test specimen was determined and recorded. Chronological histories were thus obtained of any symptoms of illness and the occurrence of death.No effects were observed when the test organisms sea lamprey, bluegill and rainbow trout were exposed to the test chemical 2-[2-[4-[(2-chloroethyl)ethylamino]-o-tolyl]vinyl]-1,3,3- trimethyl-3H-indolium chloride for 24 hrs. Thus, the EC0 value was determined to be 5 mg/l.
In a supportingstudy from authoritative database (ECOTOX database, 2018) of the read across chemical 2-(2-{4-[(2-chloroethyl)(methyl)amino]phenyl}vinyl)-1,3,3-trimethyl-3H-indolium chloride (CAS no. 3648-36-0),short term toxicity to Leuciscus idus (Ide, Silver or Golden Orfe) study was carried out for 48 hrs. The study was based on the effects of the read across compound 2-(2-{4-[(2-chloroethyl)(methyl)amino]phenyl}vinyl)-1,3,3-trimethyl-3H-indolium chloride (CAS no. 3648-36-0) on Leuciscus idus in a static freshwater system at a temperature of 10 to 13°C and pH 7.2 to 7.4, respectively. Hardness of water is 120 to 140 mg/l CaCO3 and dissolved oxygen is ˃4 mg/l, respectively. Leuciscus idus (Ide, Silver or Golden Orfe) was used as a test organism. Based on effect on mortality of the test organism Leuciscus idus, the 48 hr LC50 value was determined to be 40 mg/l, respectively. Thus, based on the LC50 value, it can be concluded that the substance 2-(2-{4-[(2-chloroethyl)(methyl)amino]phenyl}vinyl)-1,3,3-trimethyl-3H-indolium chloride can be considered as toxic to aquatic organisms and thus can be considered to be classified in aquatic chronic category 3 as per the CLP classification criteria.
Another short term toxicity to Leuciscus idus (Ide, Silver or Golden Orfe) study was carried out for 48 hrs (ECOTOX database, 2018). The study was based on the effects of the read across compound 2-(2-{4-[(2-chloroethyl)(methyl)amino]phenyl}vinyl)-1,3,3-trimethyl-3H-indolium chloride (CAS no. 3648-36-0) on Leuciscus idus in a static freshwater system at a temperature of 13°C and pH 7.0 to 8.0, respectively. Hardness of water is 270 mg/l CaCO3 and dissolved oxygen is ˃5 mg/l, respectively. Leuciscus idus (Ide, Silver or Golden Orfe) was used as a test organism. Based on effect on mortality of the test organism Leuciscus idus, the 48 hr LC50 value was determined to be in the range 38 to 75 mg/l, respectively.Thus, based on the LC50 value, it can be concluded that the substance 2-(2-{4-[(2-chloroethyl)(methyl)amino]phenyl}vinyl)-1,3,3-trimethyl-3H-indolium chloride can be considered as toxic to aquatic organisms and thus can be considered to be classified in aquatic chronic category 3 as per the CLP classification criteria.
For the same read across chemical compound 2-(2-{4-[(2-chloroethyl)(methyl)amino]phenyl}vinyl)-1,3,3-trimethyl-3H-indolium chloride (CAS no. 3648-36-0), short term toxicity to Oncorhynchus mykiss (Rainbow Trout) study was carried out for 48 hrs (ECOTOX database, 2018). The study was based on the effects of the read across compound 2-(2-{4-[(2-chloroethyl)(methyl)amino]phenyl}vinyl)-1,3,3-trimethyl-3H-indolium chloride on Oncorhynchus mykiss in a static freshwater system at a temperature of 13°C and pH 7.0 to 7.4, respectively. Hardness of water is 180 mg/l CaCO3 and dissolved oxygen is ˃7 mg/l, respectively. Oncorhynchus mykiss (Rainbow Trout) was used as a test organism. Based on effect on mortality of the test organism Oncorhynchus mykiss, the 48 hr LC50 value was determined to be 80 mg/l, respectively. Thus, based on the LC50 value, it can be concluded that the substance 2-(2-{4-[(2-chloroethyl)(methyl)amino]phenyl}vinyl)-1,3,3-trimethyl-3H-indolium chloride can be considered as toxic to aquatic organisms and thus can be considered to be classified in aquatic chronic category 3 as per the CLP classification criteria.
Thus, based on the overall reported results for target chemical 2-[2-[4-[(2-chloroethyl)ethylamino]-o-tolyl]vinyl]-1,3,3- trimethyl-3H-indolium chloride (from peer reviewed journal) and for its read across substance (from authoritative database ECOTOX),it can be concluded that the EC0 value of the test substance 2-[2-[4-[(2-chloroethyl)ethylamino]-o-tolyl]vinyl]-1,3,3- trimethyl-3H-indolium chloride was determined to be 5 mg/l.
