Developing an international consensus on DDT: a balance of environmental protection and disease control

The Stockholm Convention on Persistent Organic Pollutants provides a framework for international action on 12 persistent, bioaccumulative and toxic chemicals of global concern. While production and use of most of the listed chemicals will shortly be eliminated, there is widespread agreement that DDT will continue to be needed for disease vector control. Science played a key role in informing policy makers from developed and developing countries who drafted the DDT provision of the convention. This paper examines both the science and the politics that contributed to an international consensus on DDT.
