The most serious source of exposure to soil lead is through direct ingestion (eating) of contaminated soil or dust. In general, plants do not absorb or accumulate lead. However, it is possible for some lead to be taken up into the plant if the soil tests high in lead. Studies have shown that lead does not readily accumulate in the fruiting parts of vegetables and fruit crops (ie corn, beans, squash, tomatoes, etc). High concentrations are more likely to be found in leafy vegetables and on the surface of root crops.

-There is more concern about lead contamination from external lead on unwashed produce than from actual uptake by the plant itself. If you garden is close to a busy street or highways, remove the outer leaves of leafy crops, peel all root crops, and thoroughly was the remaining produce in water containing vinegar (1%) or soap (.5%).+There is more concern about lead contamination from external lead on unwashed produce than from actual uptake by the plant itself.
