Scientists have struggled to identify which small microplastics persist longest in the environment, given their ubiquity in waterways.

Similarly, a scientific struggle has been to measure their abundance, especially at the smaller end of the size range. That’s where they’re most likely to be consumed by foundational species near the bottom of the food web, like zooplankton.

Researchers from the Bigelow Laboratory for Ocean Sciences and the University of Minnesota-Duluth have now developed an innovative analytical method. It combines different specialized techniques, including flow cytometry, to characterize and count these small varieties of microplastics.
