||Six raw agricultural crops (carrots, field corn, onions, rice, spinach, and tomatoes) were collected from major U.S. growing areas uncontaminated by human activities other than normal agricultural practices. Handling, preparation, and analysis of the 1215 samples were performed under carefully controlled conditions. Cadmium and lead were determined by differential pulse anodic stripping voltammetry and Ca, Cu, Fe, K, Mg, Mn, Mo, Na, Ni, P, and Zn by inductively coupled plasma emission spectroscopy. Mean Cd concentrations in carrots, field corn, onions, rice, spinach, and tomatoes were 0.028, 0.012, 0.011, 0.012, 0.065, and 0.017 micrograms/g (wet weight), respectively; mean Pb concentrations in these crops were 0.009, 0.022, 0.005, 0.007, 0.045, and 0.002 micrograms/g wet weight, respectively.
