Applicant's summary and conclusion
- Conclusions:
- Under the conditions of this test, LD50 is 147 mg/kg bw.
- Executive summary:
Parodi at al.(1981) investigated to demonstrated for sixteen compounds a qualitative correlation with carcinogenic activity and induction of DNA damage in mamalian cells or bacterial mutagenicity. The dose level to be used in in vivo genotoxicity assay was selected from known LD50. As no data was available in litterature for 2,4 -Toluendiamine, an acute toxicity was performed. Male Sprague-Dawley rats (4 animals for each dose) were administered i.p. a series of doses of 2,4 -toluendiamine increasing serially by a constant factor. The LD50 at 5 days was calculated according to the method of Weil (1951), only after the doses given were sufficient to obtain both 0% and 100 % mortality. No data on mortality, clinical signs, body weight, or gross pathology were reported. The obtained LD50 is 147 mg/kg bw. Because of documentation insufficient for assessment, this data was classified unreliable.
