Serum levels of certain trace elements (Ag, Co, Cr) in healthy subjects (part II).

In 95 healthy subjects including 55 women and 40 men the serum levels of Ag, Co and Cr were determined by means of neutron activation analysis using the method of gamma spectrometry without separation of different elements from the sample. It was found that people aged over 60 years had higher serum silver levels than younger subjects. In women a statistically significantly higher serum cobalt level was demonstrated in relation to men. Men and women aged over 60 years had serum chromium levels very similar while women aged below 60 years had lower serum chromium levels.
