Pure Earth is a New York City-based international not-for-profit organization founded in 1999 that works to identify, clean up, and solve pollution problems in low- and middle-income countries, where high concentrations of toxic pollution have devastating health impacts, especially on children. These communities suffer disproportionately from pollution-related diseases. Pure Earth remains the only significant organization of its kind working to solve pollution on a global scale. Pure Earth's work focuses on two key pollutants: lead and mercury. The Global Lead Program works on reducing lead poisoning from three key sources poisoning millions of children in low- and middle-income countries: the unsafe and informal recycling of used lead-acid (car) batteries; lead-glazed pottery, and contaminated spices. The Global Mercury Program works to reduce mercury from artisanal and small scale gold mining communities around the world by training miners to go mercury free, and helping miners in the Amazon rainforest restore land damaged by mining. Pure Earth is known for the Toxic Sites Identification Program, a global movement to find and clean up the world’s most toxic sites. The program has trained over 500 pollution investigators and 90 government representatives worldwide, who have identified and mapped over 5000 toxic hotspots in communities around the world. The data they collect has built an “unprecedented public database of toxic sites” that helps local communities and governments plan clean up to protect residents. Pure Earth is also known for initiating the

Toxic Sites Identification Program

Pure Earth'
Toxic Site Identification Program
(TSIP) works to identify and screen contaminated sites in low- and middle-income countries where public health is at risk. Pure Earth has trained more than 400 toxic sites investigators around the world to find, map and assess polluted sites that pose health risks in their communities. To date, TSIP investigators have identified more than 3,100 sites in over 50 countries. These sites alone represent a potential health risk to more than 80 million poor people. The data collected by TSIP investigators is entered into Pure Earth's database of polluted sites, the largest database of its kind. This information is made accessible to governments so that they can formulate plans to prioritize action on pollution that poses the most risk to populations. The public can view the data a

The Global Alliance on Health and Pollution

In July 2012, Pure Earth convened a third meeting of world leaders and experts on pollution at the Rockefeller Foundation's Bellagio Center in Italy. The Global Alliance on Health and Pollution (GAPH) was formed that year by Pure Earth, the World Bank, UNEP, UNDP, UNIDO, Asian Development Bank, the European Commission, Ministries of Environment and Health of many low- and middle-income countries to address pollution and health at scale. Blacksmith serves as Secretariat for the GAHP. Blacksmith began coordinating an international effort to create a global alliance in 2008. The effort was formerly called the Health and Pollution Fund.

Pure Earth was founded as the Blacksmith Institute in 1999. In 2014, Blacksmith launched a new initiative – ''Blacksmith Institute for a Pure Earth'' – with English actor

Dev Patel Dev Patel (; born 23 April 1990) is a British actor. His breakthrough came in 2008 with the leading role of Jamal Malik in Danny Boyle's drama ''Slumdog Millionaire'', for which Patel was nominated for the BAFTA Award for Best Actor in a Lead ...

as celebrity ambassador. Patel worked closely with Blacksmith to suggest the new name, and will help support efforts to raise awareness about toxic pollution, an issue he says he first grew aware of after filming in India. Blacksmith will slowly transition to a new name – Pure Earth – with the aim of broadening awareness of global toxic pollution issues to the general public.
