ABSTRACT

Sampling for microplastics requires robust planning to ensure representative results. New and proposed ASTM Standards and Practices provide vetted approaches to sample collection, preparation, analytical identification, and reference sample use. For EPA and related purposes, these approaches fit well into a project Quality Measurement System. This talk will present insights into the development of appropriate microplastic sample planning with emphasis on ASTM standards for sample collection and analysis. The presentation will emphasize how to select and employ both count-based and/or mass-based analytical methods in study design. Specifics will include method Quality Control approaches for both identification approaches as well as planning sampling based on anticipated data use.
