A study on the acute inhalation toxicity of CaTG on rats has been
conducted in accordance with OECD Guideline No. 403. Mortality occurred
in a few rats at 1022 mg/m3and above. However, any
concentration-dependence or particular sex-dependence was not observed.
The maximum technically achievable concentration was 2729 mg/m3.
The exposure to this exposure level caused lingering and pronounced
irritant effects in the upper and lower respiratory tract. Mortality is
considered to be linked to acute lung edema. Due to the absence of
concentration-dependent changes in particle size, the LC50is
greater than the maximum technically attainable concentration. Due to
technical aspects as well as animal welfare considerations, the testing
of CaTG at around 3000 mg/m3is considered to meet the
criteria of limit-test of contemporary testing guidelines.
