Our country urgently needs resources and expertise to be able to control active emissions, prevent future pollution, and clean up legacy pollution to protect human health and the environment. > Neric Acosta, Presidential Adviser for Environmental Protection, Office of the President, Government of the Philippines 4 Practical Strategies by Type of Toxic Site Solution: Develop appropriate tailings management Toxic exposures can be categorized into a series of systems.

In important issue for each country, there is a need to first: an Asia that is rapidly — identify hotspots, and cluster them into type of exposure, toxicant and solution; industrializing and —define resources needed to mitigate health impacts; urbanizing. — coordinate international and national resources for effective management, and health risk mitigation. > Rajat Nag, Managing Director General, Asian Development Bank Philippine mercury-free technique to extract gold. A large number of low- and middle-income countries need assistance and transfer of other country experience, technical know-how, successful replicable models, and resources to address these problems. Global Alliance on Health and Pollution (GAHP) The Global Alliance on Health and Pollution (GAHP) was formed in 2012 to assist low- and middle-income countries to implement solutions to the problems posed by chemicals and wastes. It is led by the Asian Such processes are at various stages of activity in Development Bank, Blacksmith Institute, the Euro- a number of countries to date, including India, pean Commission, UN Development Program, UN China, South Africa, the Philippines, Indonesia, Environment Program, UN Industrial Development and Mexico, among others.
