Test Method for Determination of Microplastics Particle and Fiber Size, Distribution, Shape, and Concentration in Waters with High to Low Suspended Solids Using a Dynamic Image Particle Size and Shape Analyzer
AI summary Read the abstract
This ASTM standard test method (duplicate of 45524 and 45915) describes how to measure microplastic particle size, shape, fiber dimensions, and concentration in water using a dynamic image particle analyzer. The method is applicable to water samples with high to low suspended solids content. Standardized test methods are critical for generating comparable microplastic data across different monitoring programs.
Significance and Use 5.1 Many microplastic particles enter the environment, including ambient waters and drinking water supplies, via wastewater sources resulting from both industrial processes and consumer products. The presence of high percentages of or
