Summary

Scientists found that when they properly account for differences in how studies measure tiny plastic particles in the air, actual global microplastic emissions appear lower than previous estimates suggested. This matters because it means earlier predictions about how much plastic pollution we're breathing in may have been overstated, though microplastics in air are still a real and ongoing concern worth monitoring closely. This is a tool/methods paper — the code itself is what's shared here, providing a more accurate way for researchers to compare microplastic measurements across different studies going forward.
