About This Map
LeadPollution.org is a repository of reputable data related to lead (Pb) exposures around the world. Developed and managed by Pure Earth, it is intended for researchers and policy makers globally.
This interactive map is a central repository, by country, for data sets, research, regulatory information and more pertaining to the global health crisis of lead exposure and poisoning. The intent of the website is to increase awareness, understand the drivers of this crisis, and accelerate the pace of solutions.
