ABSTRACT
Much evidence has been collected and entered in the literature showing the severe and extensive .respiratory effects in human beings exposed in industries and in animals exposed in laboratories to various cadmium compounds. These symptoms can be noted in cases of acute exposure to high concentrations as well as in cases of chronic exposure to low concentrations of cadmium. In this review special attention will be given to the effects of chronic exposure. As the acute effects serve to show the potential hazards of cadmium, a brief review is given also of the nature of such effects as well as the concentration ranges associated with them.
