Overview

Experimental analysis reveals chlorpyrifos toxicity effects on embryonic and larval stages of Anabas testudineus, indicating concerning developmental risks.

Key Points

  • Chlorpyrifos significantly reduces hatching success and increases mortality rates in Anabas testudineus embryos.
  • The LC50 values for embryos at 24 hours were determined to be 0.261 μgL−1, indicating substantial toxicity.
  • Physical deformities in larvae include yolk sac edema and inflammation of the swim bladder due to chlorpyrifos exposure.
  • Findings highlight the negative impact of chlorpyrifos on the early developmental stages of aquatic species.
