||As part of a continuing national and international survey of cadmium ingestion, a study was performed to estimate the daily intake of cadmium and other metals in two low-income populations in the U.S.: rural blacks and urban hispanics of Mexican-American heritage. More than 260 persons were recruited and surveyed. Feces, urine, and blood were collected from each participant and analyzed for Cd, Pb, Zn, Ca, and Fe; blood was also analyzed for iron-binding capacity and hemoglobin; and urine was also analyzed for beta2-microglobulin and creatinine. Results indicate that ingestion rates of cadmium in both populations are slightly lower than levels reported previously for the general U.S. population, and ingestion rates of lead are considerably lower (less than one half) than levels reported previously for the general population. It was concluded that nonoccupational exposures of these two population groups to cadmium and lead through ingestion is no greater than and is probably less than that experienced by the general population of the United States.
