Applicant's summary and conclusion
- Conclusions:
- The repeated dose toxicity LOEL (Lowest observed effect level) of clioquinol to rat by the inhalation route was estimated at a dose concentration of 159.4855 mg/kg bw/day.On the basis of this LOEL value it is concluded that the test substance is not toxic to rat by the inhalative route below the above mentioned dose.
- Executive summary:
The repeated dose toxicity LOEL (Lowest observed effect level) of clioquinol to rat by the inhalation route was estimated at a dose concentration of 159.4855 mg/kg bw/day.On the basis of this LOEL value it is concluded that the test substance is not toxic to rat by the inhalative route below the above mentioned dose.
