VARIATION IN LEAD CONCENTRATION IN THE EDIBLE TISSUES OF CROP PLANTS
FIGURE 13.24 Crops grown on contaminated soil vary in the extent to which they concentrate heavy metals in their edible tissues. Root crops (e.g., potatoes) and leafy greens (e.g., spinach and cabbage) generally concentrate more heavy metals in their edible tissues, compared with crops producing edible fruits (e.g., tomatoes and eggplant).
