  • Title: Effects of inhalation exposure to carbon disulfide and its combination with hydrogen sulfide on embryonal and fetal development in rats.
    Author: Saillenfait AM, Bonnet P, de Ceaurriz J.
    Journal: Toxicol Lett; 1989 Jul; 48(1):57-66. PubMed ID: 2749780.
    Abstract:
    Pregnant rats were exposed to 0, 100, 200, 400 or 800 ppm of carbon disulfide (CS2), 100 ppm of hydrogen sulfide (H2S) alone or in combination with 400 and 800 ppm CS2, 6 h/d during days 6-20 of gestation. Maternal reproduction and fetal parameters were evaluated on gestational day 21. Treatment with 100 or 200 ppm CS2 or with 100 ppm H2S caused no maternal toxicity or adverse effects on the developing embryo or fetus. Exposure to 400 or 800 ppm CS2 resulted in a low incidence of club foot and in a significant reduction of maternal weight gain. Significant increases in unossified sternebrae occurred at 800 ppm CS2 and reduction of fetal body weight at 400 and 800 ppm CS2. The latter effect was enhanced by combination with 100 ppm H2S. These results support the conclusion that, at levels of exposure associated with maternal toxicity, CS2 leads to an increase in incidence of club foot and to fetal toxicity which is enhanced by simultaneous exposure to H2S.
