5. Toxicity Substance ID: 71–43–2<br />

______________________________________________________________________________<br />

Species: other: mouse, rabbit Sex: female<br />

Strain: other: CFLP (mouse), New Zealand white (rabbit)<br />

Route of administration: inhalation<br />

Exposure period: mouse: gestation days 6–15, sacrifice at day 18;<br />

rabbit: gestation days 7–20, sacrifice at day 30;<br />

the day of finding a vaginal plug was taken the first<br />

day og gestation<br />

Frequency of treatment: mouse: for 24 h/day continuously or for 3x4 h/day<br />

intermittently<br />

rabbit: for 24 h/day continuously<br />

Duration of test: mouse: day of sacrifice day 18 of pregnancy<br />

rabbit: day of sacrifice day 30 of pregnancy<br />

Doses: mouse/rabbit: 0.5, 1.0 mg/l (converting to about 155<br />

and 310 ppm); 15 animals/dose<br />

Control Group: yes, concurrent vehicle<br />

Method: other<br />

GLP: no data<br />

Test substance: no data<br />

Remark: mouse: CFLP (LATI–Goedoelloe, Hungary) strain mice were<br />

used.<br />

Control group consisted of 115 females exposed to air. Dams<br />

were killed on day 18 of pregnancy and foetuses examined as<br />

described elsewhere (Hudak A. & Ungvary G. Toxicology 11,<br />

55–63, 1978).<br />

rabbit: Control group consisted of 60 dams exposed to air.<br />

Dams were killed on day 30 of pregnancy and foetuses<br />

examined as described elsewhere (Ungvary G. Munkavedelem 29,<br />

207–216, 1983).<br />

Result: mouse:<br />

no effects were seen on the numbers of live foetuses or on<br />

the percentage of minor anomalies or of total malformations.<br />

A statistically significant increase of the ratio of weight<br />

retarded and of skeletally retarded fetuses as well as an<br />

increased ratio of absorbed or dead fetuses was observed at<br />

both concentration levels.<br />

rabbit:<br />

at 1.0 mg/l there were statistically significant decreases<br />

in maternal weight gain, mean fetal body weights and an<br />

increase in the number of abortions as well as increased<br />

ratios for dead or reorbed fetuses and for minor<br />

abnormalities. No evidence for developmental toxicity was<br />

observed at the lower dose level of 0.5 mg/l.<br />
