ClearA modified methodology for extraction and quantification of microplastics in soil
Researchers developed and validated an improved methodology for extracting and quantifying microplastics from soil samples using optimized density separation with different salt solutions. The method achieved high recovery rates for various polymer types and particle sizes while minimizing organic matter interference.

Upgraded Protocol for Microplastics’ Extraction from the Soil Matrix by Sucrose Density Gradient Centrifugation
Extracting microplastics from soil is technically difficult because soil contains dense organic matter and particles that look similar to plastic under analysis.
