One of the main outcomes of the eleven meetings of the Working
Party was the recognition of the importance of interdisciplinary
studies linking regional geochemistry with plant, animal and human
health. The effects of major element deficiencies or excesses on
plant health are well known; this is not the case for trace
elements. In fact, rapid and reliable analytical methods for
determining trace element abundances have only recently become
available, and it is to be expected that important new information
on trace element levels will be forthcoming. This, however, is only
part of the problem because other factors such as element
speciation, uptake and transmission may be more significant than
total concentration. The pathways of elements from crops to animals
are relatively well defined, but the aetiology of diseases
attributable to elemental inadequacies or excesses is generally
quite complex. Nevertheless, there is good evidence for diseases in
livestock in the British Isles induced by deficiencies of Cu, Se
and Co and Mo excess. On a world scale there is also convincing
data on the effect of Na, P and I deficiencies and F excess on
animal health. What is generally lacking, however, is adequate
interaction between geochemists and biochemists, veterinary
scientists and other concerned with animal health. Interpretation
of geochemical data is complex as are connections between elemental
abundances and the health of animals.
