AN OVERVIEW OF DISTRIBUTION PATTERNS OF TRACE ELEMENTS IN SOILS AND PLANTS

The objective of this paper is to examine and review some of the associations between the trace element composition of plants and human health, and to point out some opportunities for additional research in this area. There are a number of pathways by which trace elements move from rocks or other geochemical reserves and enter the human body. The pathway from rocks-to-soils-to-plants and then to the diet of animals and man is often a very important pathway and will be the focal point of this paper.
