    Acrolein exposure during chick embryo development caused significant mortality and malformations at higher doses. Embryonic development was impacted, with observed abnormalities in limbs, viscera, eyes, and neck.

    Area of Science:

    • Toxicology
    • Developmental Biology
    • Teratology

    Background:

    • Acrolein is a volatile aldehyde found in environmental pollutants.
    • Understanding its impact on embryonic development is crucial for public health.

    Purpose of the Study:

    • To investigate the embryotoxic and teratogenic effects of acrolein in chick embryos.
    • To determine dose-dependent effects and identify specific malformations.

    Main Methods:

    • Fertilized chick eggs (600) were incubated for 48 or 72 hours.
    • Acrolein solutions were injected into air sacs at varying doses (0.001–0.1 mg/egg).
    • Embryos were examined at Day 13 for survival and gross malformations.

    Main Results:

    Related Experiment Videos

  • Acrolein exposure at 48 hours of incubation led to dose-dependent mortality, decreasing survival from 80% to 0%.
  • Embryonic mortality did not significantly increase at 72 hours of incubation.
  • Observed malformations included limb defects, everted viscera, microphthalmia, short/twisted necks, and hemorrhage.

    • Conclusions:

    • Acrolein exhibits dose-dependent embryotoxicity in chick embryos.
    • Acrolein is a moderate teratogen, inducing various gross abnormalities.
    • The stage of incubation (48 vs. 72 hours) influenced mortality but not the types of malformations observed.
