water
Details on exposure:
Drinking water solutions were prepared daily
Concentration in vehicle: 0, 0.015, 0.075 or 0.3 % (w/v)

Details on study schedule:
After 9 weeks of treatment, 10 male and 10 female rats dosed with 0 or 0.015 % were mated for 20 days (daily changes of partner). After 27 weeks of treatment, groups of 10 rats dosed with 0.075 and 0.3 % were mated in the same way. For the F1 generation a comparable dosage/treatment regimen was used and at an appropriate age and weight they were used for breeding the F2-generation. The F3-generation was bred from the F2-generation in the same way.
