Mercury uptake by 8 food crops was studied in a growth chamber experiment involving 3 rates of HgCl/sub 2/ applied to soil. Mercury concentrations, on dry weight basis, in various parts of leaf lettuce, spinach, broccoli, cauliflower, peas, oats, radishes, and carrots were higher in root portions than the above-ground sections. Content of roots ranged from 0.387 ..mu..g Hg/g of lettuce roots to 2.447 ..mu..g Hg/g of cauliflower roots when 20 ..mu..g Hg/g of soil were applied. At the same treatment rate and among the edible plant parts, pea seeds and oat grain accumulated the least mercury while spinach leaves and radish tubers contained the highest concentrations, averaging 0.695 and 0.663 ..mu..g Hg/g of plant material. 5 references, 1 table.
