Implication

The study assesses organochlorine pesticide levels in surface water, revealing low health risks and suggesting the need for monitoring.

Key Points

  • The research aims to evaluate the contamination of surface water with organochlorine pesticides and assess health risks.
  • Collected twelve water samples from four sites in Gazipur.
  • Used liquid-liquid extraction with dichloromethane for analysis.
  • Analyzed samples using gas chromatography with electron capture detector.
  • Conducted principal component and hierarchical cluster analyses to identify pollution sources.
  • Calculated average daily dose, hazard quotient, and cancer risk.
  • Six samples were found contaminated with residues of endosulfan I.
  • Several pesticides were below detection limits in all samples.
  • Measured analyte concentrations varied across different pesticides.
  • Pollution sources were linked to diverse human activities.
  • Health risk assessments indicated no significant risks based on USEPA thresholds.
