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
Summary
This document is another version of the ASTM standard test method for determining microplastic particle and fiber size, distribution, shape, and concentration in water using dynamic image particle analysis (same as 45524 and 45910). Standardized methods like this are essential for producing data that can be compared across different studies and monitoring programs worldwide.
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
