Cadmium concentrations were measured in the liver, kidney, and hair of 107 individuals from the Cincinnati area. The tissue samples were obtained from hospital and coroner autopsy cases and represent a cross‐section of individuals from fetal to old age. The sections used were standardized and analyzed for cadmium by atomic absorption. Information obtained at the time of autopsy included the cause of death, the conditions of the tissues, the body height and weight, the amount of anthracosis in the lungs, as well as age, sex, and race.
