Lead absorption from soil into legumes
Bean and peanut seedlings were planted into a 50:50 mixture of soil and terralite. After one month of growth, a 1% lead acetate solution was added to half the plants on successive days to a total of approximately 200 ml/kg dry soil. The beans did not grow as well in leaded soil, and peanuts did not show any inhibition of growth. The beans also showed spotty discoloration. In further experiments, beans and peanuts were germinated and transplanted directly into leaded soil containing 820 microgram/gram of dry soil. Again, while the beans showed poor growth, the peanut plants grew as well in leaded soil as in soil without lead. It appears that lead is absorbed into the plants and enriched in the leaves. 5 references, 2 tables.
