A fluorescence microscopy protocol for soil microplastics found the highest concentration in farmland at 1.04×10^5 particles/kg, with <100 μm particles dominating across sites.
- Why it matters: Reliable quantification in complex soil is hindered by soil organic matter that can create background fluorescence, and by extraction efficiency that affects measured microplastic counts.
- What they did: The workflow optimized SOM digestion and microplastics extraction, testing H2O2, Fenton’s reagent, and HNO3 for background removal and CaCl2 versus ZnCl2 for extraction, then used Nile red staining and image-based counting.
- The result: HNO3 removed background fluorescence most effectively (89% in loam, 82% in clay) and CaCl2 (1.4 g/cm^3) enabled recoveries of 78–80% for PP and 61–70% for PVC, enabling field detection at three land-use sites.
