DescriptionMethodology to quantify microplastics.png
English: Methodology to quantify microplastics. For sediment tests, the sediment sample is removed and then slurried to increase water density which allows the microplastic particles to float. For marine trawls, plankton nets are used and then the water sample is run through a coarse filter to remove microplastics and other large contaminants. Mineral salts may be added to increase buoyancy of microplastics. After the solution undergoes evaporation, the particles may be stained with dyes to aid in visibility before they are identified via microscopy.
