Why it's stuck
An estimated 815 million children have blood lead above 5 µg/dL. A Center for Global Development working group found only about $11 million a year of philanthropic funding for the problem in these countries, and said the share of exposure from each source is not yet well characterized.
What we'd try
Run uncertainty-aware exposure simulations for each country, combining Pure Earth's open measurements of 5,007 products with diet and household survey data, and check against Georgia's and Mexico's national blood lead surveys.
Why we stopped
Rejected on prior art and tractability: Pure Earth and Rethink Priorities already built this source-attribution model from the same data and called it unreliable for lack of field data (leaching rates, product-use frequency, representative samples), which compute cannot supply.
