Summary Mercury uptake by 8 food crops was studied in a growth chamber experiment involving 3 rates of HgCl2 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 ug Hg/g of lettuce roots to 2.447 ug Hg/g of cauliflower roots when 20 ug 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 ug Hg/g of plant material.
