The genesis of what has evolved into Medical Geology can be traced back to the realization of the environmental factor as one of the causal factors affecting health although, according to Finkelman et al. (2001), the impacts of geologic materials on human health have been recognized for thousands of years. This developed in response to apprehension of environmental degradation arising out of anthropogenic impacts resulting from industrial technology. Silent Spring (Carson, 1962) is the earliest expression of this apprehension has come to be defined by the health and environment cause-effect framework given in Fig. 1 below by WHO (2000).
