Area of Science:

  • Environmental Science
  • Ecotoxicology
  • Developmental Biology

Background:

  • Microplastics are a growing global pollutant with known risks to animal health.
  • The ecotoxicological impact of microplastics on avian embryo development remains largely unknown.
  • Opaque eggshells limit direct observation of embryo development under pollutant stress.

Purpose of the Study:

  • To investigate the effects of microplastics on quail embryo development.
  • To develop a novel method for visually monitoring embryo development under pollutant exposure.
  • To assess the ecotoxicological impact of microplastics on avian embryonic growth and organ development.

Main Methods:

  • A novel 'hatching without an eggshell' technique was employed for visual monitoring.
  • Fertilized quail eggs underwent cleaning, disinfection, and incubation stages.
  • Exposure to microplastics was followed by short-term incubation and sample extraction.

Main Results:

  • Microplastic-exposed quail embryos showed statistically significant differences in wet weight and body length compared to controls.
  • The proportion of the liver in microplastic-exposed embryos significantly increased.
  • External incubation factors like temperature, humidity, and rotation were also evaluated.

Conclusions:

  • Microplastic exposure adversely affects quail embryo development, impacting growth metrics and organ development.
  • The 'hatching without an eggshell' method offers a valuable tool for studying pollutant effects on avian embryos.
  • This research contributes to understanding microplastic ecotoxicology and provides a novel approach for embryo research.
