Lead Contamination of Sycamore and Soil from Lead Mining and Smelting Operations in Eastern Missouri¹

ABSTRACT

Lead concentrations of both plant tissue (Platanus occidentalis L.) and soils (total and available) were determined for various sampling locations within a 10-km radius of two lead smelters and two lead mines located in eastern Missouri.

Lead content of washed foliage ranged from 1.3 to 1,120 ppm, while values in twigs, which were generally lower, ranged from 1.8 to 320 ppm. Nitric acid-extractable lead from soils ranged from 7 to 62,000 ppm while 3% acetic acid-extractable lead varied from 1 to 20,400 ppm.

Largest lead levels for both soils and plants occurred at the smelter sites. It appeared that both the chemical form, level, and particulate size of atmospheric lead and the nature of soil lead could play an important role in the uptake of lead by the plant tissue.

Key Words: Platanus occidentalis L. • lead pollution
