Abstract
The contents of cadmium, copper and zinc, and the distribution of these metals among the protein fractions of human parotid saliva were determined by atomic absorption spectrometry. The proteins were separated by gel filtration. The contents of metal were found to be 3.5 ppb Cd, 88 ppb Cu and 49 ppb Zn. In the protein fractions, zinc was distributed over a wide range, the highest contents being found in proteins of high molecular weight. Cadmium was found in the fractions which contained the largest amounts of zinc. Copper was present in a relatively narrow range of proteins of intermediate molecular weight.
