This district-wide prevention effort will examine and test ways to comprehensively reduce lead in Bangladesh from three major sources: batteries, paint and adulterated turmeric. Stakeholders will be engaged in a process of publicly identifying and eliminating lead hot spots. Impact will be tracked by measuring changes in lead concentrations in maternal and child blood, soil, paint and turmeric. Factors that convince stakeholders to take action will be systematically addressed. In two years, lead exposure in the district will be reduced, benefiting nearly five million people, and the approach will serve as a model for other regions around the world.
