Materials and methods
Test guideline
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- - Principle of test: A 14-day repeat dose toxicity study with 2-chlorophenol was performed including evaluation of sister chromatid exchanges. Groups of 12 male and female CD-1 mice were exposed to 2-chlorophenol at dose levels of 35, 69 and 175 mg/kg bw/day by oral gavage once daily for 14 consecutive days. Vehicle control animals received the vehicle, corn oil, only. In addition a treatment naive and a positive control group (cyclosphosphamide, 25 mg/kg bw) were included.
- Parameters analysed / observed: SCE (testes and bone marrow). - GLP compliance:
- not specified
- Type of assay:
- sister chromatid exchange assay

- Negative controls validity:
- not specified
- Positive controls validity:
- not specified
- Additional information on results:
- Mortality was observed in the highest dose group. In the mid-dose group, a decrease in body weight was observed. Administration of the low and mid-dose caused hyperactivity in the test animals. No alterations on clinical or haematological parameters were observed. Females revealed reduced liver, brain and spleen weights. No gross anomalies were observed. No biologically or statistically significant compound-related effects on DNA repair were observed in the examined tissues.
