Fate, transport, and interactions of heavy metals.

Mishandling of hazardous wastes, like their unauthorized disposal in abandoned dump yards or sites, in river beds, estuaries or in the sea, causes substantial damage to the environment and its resources and, given the persistence and toxicity of these pollutants, they can seriously damage human health and quality of life. The importance of controlling management, transport, and disposal of toxic and hazardous substances in the years to come will be a crucial issue in the design and implementation of public policies. This is especially true for residents of such areas as the border between the United States and Mexico, where historically hazardous wastes have been a public health and environmental problem. The aim of this Conference on the Fate, Transport, and Interactions of Metals, A Joint United States-Mexico Conference, co-sponsored by the National Institute of Environmental Health Sciences, Superfund Basic Research Program, the National University of Mexico, Program for the Environment and the Pan American Health Organization, and hosted by the University of Arizona Center for Toxicology, College of Pharmacy, is to begin a joint effort by the United States and Mexico to better understand the complex problems related to heavy metals as hazardous wastes.
