- Validity criteria fulfilled:
- not specified
- Conclusions:
- The median lethal concentration (LC50) value for 4-chloro-1-methylpiperidine on Danio rerio in a 96 hours study was estimated to be 243.66 mg/L on the basis of effects on mortality.
- Executive summary:
Using the OECD QSAR toolbox version 3.3 with log kow as the primary descriptor and considering the five closest read across substances, the short term toxicity on fish was predicted for target substance 4-chloro-1-methylpiperidine (CAS no. 5570-77-4). LC50 value was estimated to be 243.66 mg/l for Danio rerio for 96 hrs. duration. Based on this value it can be concluded that the substance 4-chloro-1-methylpiperidine is considered to be non-toxic to fish at environmentally relevant concentrations and can be considered to be not-classified as per the CLP classification criteria.

Additional information
Five studies from prediction reports and experimental study from peer reviewed journal and authorative database for short term fish toxicity endpoint for test chemical 4-chloro-1-methylpiperidine (Cas no. 5570-77-4) with relevant read across which is close to target using Log Kow as descriptor were reviewed as follows:
Using the OECD QSAR toolbox version 3.3 with log kow as the primary descriptor and considering the five closest read across substances, the short term toxicity to fish was predicted for 4-chloro-1-methylpiperidine (Cas no. 5570-77-4). LC50 value was estimated to be 243.66 mg/L on Danio rerio (previous name: Brachydanio rerio) for 96 hrs duration.
In another prediction done using the EPI Suite ECOSAR version 1.10 the 96 hours LC50 was estimated to be 261.626 mg/l on Fish for substance 4-chloro-1-methylpiperidine (Cas no. 5570-77-4) on the basis of mortality effects.
And Danish QSAR study indicate 96 hrs LC50 value of test substance 4-chloro-1-methylpiperidine on Fathead minnow was estimated by three different models i.e, Battery, Leadscope and SciQSAR used within Danish QSAR database. Based on mortality, the 96 hrs LC50 value was predicted to be 133.89 mg/l.
Above all predictions assist by experimental study for read across chemical Isopropyl amine (Cas no. 75-31-0) from peer reviewed journal The journal of toxicological science 7(3): 193-203;1982 which suggest The acute toxicity of nitrogen compounds including chemical Isopropyl amine was investigated in order to observed toxicity effects of chemicals on fish species Oryzias latipes (Japanese Medaka). During experiment chemical dissolved in distilled water or n-octanol at the concentration of 100 mg/liter.And vehicle selected as Ethanol at concentration 1ml as needed. Test performed in static freshwater on test species Oryzias latipes at 25 deg.C temp.10 fish per vessels was used. And Determination of dissolved oxygen checked periodically with the help of Electrode sensor. In experiment measured concentration of 1000 mg/l was taken. After 48 hrs exposure period the median lethal concentration (LC50) was observed to be 1000 mg/l.
One another read across chemical Diisopropylamine (Cas no. 108-18-9) from authorative database suggest in Acute fish toxicity study, the lethal concentration (LC50) was determined for test substance Diisopropylamine with an exposure period of 96 hrs. on the basis of effects on mortality. Test organism was used as Danio rerio (Zebra Danio) in static freshwater system. Test condition maintained as 209.43 mg/L CaCO3 hardness; 23 deg.C test temp.pH 8.2 and dissolved oxygen >6.5 mg/L.From experiment the Lethal concentration to 50% of test organisms(LC50) on the basis of Mortality effect was observed to be 680 mg/l for exposure period of 96 hrs.(Ecotox database;2017)
All the above studies for target and read across substance indicate that the chemical is likely to be non toxic to fish with lethal concentration range 133.89-1000 mg/l. Thus, based on the available information, the test substance 4-chloro-1-methylpiperidine (Cas no. 5570-77-4) can be considered as non toxic to aquatic environment and thus not classified in aquatic environment as per the CLP criteria.
