Similarly, although health scientists have a rapidly expanding understanding of individual physiology and the epidemiology of human populations on local to global scales, most modern public health practitioners have only limited awareness of the extent to which the earth environment impinges on public health. Although valuable linkages do currently exist between the earth science and public health communities, the limited extent of interdisciplinary cooperation has restricted the ability of scientists and public health workers to solve a range of complex environmental health problems, with the result that the considerable potential for increased knowledge at the interface of earth science and public health has been only partially realized.

Volcanic aerosols, gases and ash, airborne and waterborne fibrous minerals, and toxic metals in soils and plants are all examples presented later in this report where earth materials have adversely affected human health (see Box 1.1)

• Evaluate the need for specific support for medical geology research, and identify any basic research needs in bioscience and geoscience re quired to support medical geology research. • Identify mechanisms for enhanced collaboration between the earth science and medical/public health communities.

Together, these books provide a comprehensive description of current understanding of the relationship between the natural environment and public health, as well as numerous examples describing the connections and interactions between these fields. Rather than attempt to cover the same material, the NRC committee sought to build on these works by focusing its endeavors on understanding the vast array of potential research directions at the interface of earth science and public health and to identify those that it considers to have the highest priority.

In these separate sections, the committee employs specific examples to focus on, and highlight, the state of present knowledge. These considerations of cause and health effect resulting from exposure to earth materials give rise to a range of research priorities for each exposure pathway -- in each case, those that have been identified by the committee require active collaboration between researchers from both the earth science and the public health communities.
