Any other information on results incl. tables
- No clearly discernible effects on maternal survival, body weight gains, number of corpora lutea, implantations and resorptions were observed.
- The number of live litters, live and dead foetuses, the foetus weights and sex ratio were not affected by treatment.
- No difference in number or kind of abnormalities (in either soft or skeletal tissues) was found between exposed and control groups.
Applicant's summary and conclusion
- Conclusions:
- Under the conditions of the test, administration of up to 88 mg/kg bw of unspecified zinc sulphate (ca. 35.2 mg or 19.9 mg Zn2+/kg bw, for anhydrate and heptahydrate, respectively) had no adverse effects on adult hamsters and their foetuses.
- Executive summary:
Female hamsters (23-25 animals/group; outbred strain of golden hamster) received daily doses of 0.9, 4.1, 19 and 88 mg unspecified ZnSO4/kg bw by gavage during days 6-10 of gestation. A control group was included. All animals were observed daily for appearance and behaviour with particular attention to food consumption and body weight. Body weights were recorded on day 0, 8, 10 and 14 of gestation. The females were sacrificed at day 14. The urogenital tract of each animal was examined in detail. Between 21 and 24 females were pregnant at term in all groups.
No clearly discernible effects on maternal survival, body weight gains, number of corpora lutea, implantations and resorptions were observed. The number of live litters, live and dead foetuses, the foetus weights and sex ratio were not affected by treatment. No difference in number or kind of abnormalities (in either soft or skeletal tissues) was found between exposed and control groups.
Under the conditions of the test, administration of up to 88 mg/kg bw of unspecified zinc sulphate (ca. 35.2 mg or 19.9 mg Zn2+/kg bw, for anhydrate and heptahydrate, respectively) had no adverse effects on adult hamsters and their foetuses.
