Tool prototype
Exposure Estimate Tool
Estimate the parts of your routine that may contribute to controllable microplastics exposure. The scoring model is intentionally transparent and conservative while the science is still developing.
How this prototype is grounded
Official agencies generally describe microplastics research as active and incomplete, especially for human health thresholds. This tool does not claim to measure biological dose. It estimates controllable exposure pathways: bottled water reliance, heated plastic food contact, household dust, textiles, and related behaviors.
U.S. EPA Microplastics Research

Summarizes FDA’s current position on microplastics/nanoplastics in food, bottled water, seafood, and food-contact materials.
WHO: Microplastics in drinking-water
Reviews occurrence in drinking water, treatment considerations, and research gaps.
