The in Vivo Measurement of Bone Lead Stores by 109Cd K X-Ray Fluorescence in a Non-Human Primate (Macaca mulatta)

The Toxicology Program of the University of Maryland and the Harlow Primate Laboratory of the University of Wisconsin are engaged in a study of the effects of low level lead exposure during infancy, pregnancy and aging of monkeys. As part of this larger research project, the relationships between previous lead exposure, current blood lead levels and bone lead levels (as assessed by 109Cd K X-ray fluorescence in vivo measurements) are under investigation in nineteen adult and ten geriatric rhesus monkeys (Macaca mulatta). This paper reports some preliminary data from these measurements.
