ANALYSIS OF BREAD PRODUCTS FOR DIETARY FIBRE AND CADMIUM CONTENT

摘要

Cadmium is a common metal that is located throughout the earth's crust and is unusual among the elements in that it is found nature, without exception, in association with zinc. The background concentrations of cadmium in uncontaminated soils are strongly dependant on the parent rocks from which the soil is derived. Soils of similar age from igneous rocks are lowest in cadmium, soils from metamorphic rocks are intermediate and soils from sedimentary rocks contain the highest concentrations of cadmium(Fleischer et al 1974).
