Overview

Randomized trial investigates microplastics depth distribution in homestead soils, highlighting environmental risks.

Key Points

  • This study examines the distribution and risk of microplastics in agricultural soils across industrial and non-industrial regions in Bangladesh.
  • Soil samples collected from two depth intervals (0–20 cm and 21–50 cm) across four regions.
  • Microplastics were extracted using density separation and identified via microscopic analysis and ATR-FTIR spectroscopy.
  • Ecological and human health risk assessments were conducted.
  • Microplastics were more abundant in surface soils (0–20 cm) compared to subsoils (21–50 cm).
  • Narayanganj and Savar exhibited significantly higher microplastic contamination levels than Mymensingh.
  • Lifetime average daily dose (LADD) and carcinogenic risk estimates for human exposure remained below acceptable thresholds.
