The Effect of Trace Elements on Lower Plants,d as the result of biogeochemical (Lounamaa, 1956; Shacklette, 1967; Doyle ., 1973; Whitehead and Brooks, 1969) and air and aquatic monitoring surveys (Laaksovirta and Olkkonen, 1977; Pilegaard, 1978; Ruhling and Tyler, 1970; Ray and White, 1979).

Michael T. Sheaff,Naveena Singhhibit trace element deficiencies which have to be corrected by applications, either to the land or directly to the crop, of appropriate chemicals in order to achieve satisfactory yields. Both excesses, and deficiencies of trace metals may, because crop composition is affected, influence animal production.

These cases of natural ‘pollution’ are, however, relatively localized, and it was not until the recent era of industrialization that widespread contaminations by heavy metals (and other classes of pollutants as well) have occurred.
