From page 2... ... 2 THE RELATION OF SELECTED TRACE ELEMENTS TO HEALTH AND DISEASE of element distribution should be compared with patterns of animal and human disease. One fruitful approach for judging whether causal relationships do exist is to compare maps of geochemical provinces, soil types, climatic conditions, plant chemistry, and water chemistry with similar patterns of animal or human disease incidence.

Measurements of the available fraction of a given trace metal for a given plant crop have met with limited success. Read the entire page →
