Overview

Randomized trial evaluates ecological and health risks of organochlorine pesticides in water and fish, suggesting urgent regulatory measures.

Key Points

  • This research aims to assess the contamination of organochlorine pesticides in water and fish from Ethiopian highland lakes and their associated ecological and health risks.
  • Evaluated 18 organochlorine pesticides in water and fish from two Ethiopian lakes.
  • Used risk quotient (RQ) for ecological risk and hazard quotient (HQ) for health risk assessments based on U.S.EPA models.
  • Measured concentrations of pesticides and compared with WHO guidelines.
  • Eight of 18 evaluated OCPs were detected in both water and fish samples.
  • Mean water concentrations ranged from 1.11 µg/L (lindane) to 15.0 µg/L (Σendosulfan), exceeding WHO guidelines for most.
  • Carcinogenic risk values for dieldrin indicated significant concern, with potential risks ranging from 10⁻⁶ to 10⁻⁴.
