Overview

Assessment reveals high PFAS levels in Dhaka's rivers, suggesting risks to ecology and public health.

Key Points

  • PFOS in sediments poses a high ecological risk, indicating urgent action is needed to address contamination.
  • Concentrations of PFAS ranged from 23.96 to 89.35 ng/L in water and 2.18 to 11.67 ng/g in sediment.
  • Assessment utilized HPLC-MS/MS for quantifying PFAS levels in three major urban rivers in Dhaka.
  • Findings stress the necessity for improved wastewater treatment and regulatory measures to combat PFAS pollution.
