Abstract
As part of a broad ecological study of lead contamination, soil samples and underground parts of some vegetables were analyzed for lead by the dithizone method. Vegetables fell into three groups: those with a relatively high Pb content (over 30 mg/kg); those with a medium Pb content (over 10 mg/kg); and those with a low Pb content (under 5 mg/kg). Variations in Pb content in the same kind of vegetables represented variations in soil Pb content and absorption. Variations between different kinds of vegetables were due to differences in plant physiology and capacity of absorption, shape and size of root, and depth of root in soil. Lead content was higher in vegetables grown in summer and fall than for the same vegetables grown in spring. Lead absorption coefficients were calculated for underground parts of vegetables according to the relation between the Pb content of the plant and total Pb content of soil and according to the relation between the Pb content of the plant and the AL-soluble Pb in soil (AL is the ammonium lactate acetic acid mixture). The latter method gave much less dispersed coefficients, indicating that AL-soluble Pb represents much more authoritative data for determining absorption coefficients than
