Effect of Natural Minerals on Immobilization of Lead in Soils of Tea Garden

WANG Hao, ZHANG Ming-kui (Department of Natural Resource Science, College of Natural Resource and Environmental Sciences, Zhejiang University, Hangzhou 310029, China)  
The soluble and exchangeable fractions of Pb in the tea garden soils are the most important pools regarding toxicity and bioavailability of Pb to tea plants. Thus, it is very important to reduce Pb solubility and bioavailability in Pb-contaminated tea garden soils. Reducing Pb solubility and bioavailability in contaminated area without removing it from the soil is one of the common practices in decreasing the negative impacts on the crops and improving the soil quality. Therefore, the aim of this work was to study the effect of natural minerals: kaolinite, bentonite, zeolite,and apatite applied to Pb-contaminated tea garden soil on water extractable and exchangeable forms of Pb. A soil derived from Pb contaminated tea garden was incubated with clay minerals of either kaolinite, bentonite, zeolite,or apatite, for 100 d. During the incubation experiment, concentrations of exchangeable and water soluble Pb in the soils were measured. Water extractable and exchangeable forms of Pb were changed by incubation and addition of minerals. The addition of clay minerals led to a significant decrease in water soluble and exchangeable forms of soil Pb during the incubation experiment, resulting in low Pb extractability. The reduction in Pb extractability decreased in the order of apatite zeolite bentonite kaolinite, and increased with increasing applied amount of the minerals and decreasing size of the minerals. The reduction in water soluble Pb due to the addition of the minerals was greater than that of exchangeable Pb in the soils. Our results clearly show that the use of natural minerals, especially of apatite and zeolite, is promising tool for reduction the availability and possible toxicity of Pb in Pb-contaminated tea garden soils. Therefore, the soils polluted with Pb may be ameliorated by addition of clay minerals, especially apatite and zeolite. Recommended amount of minerals for ameliorating Pb-contaminated soil is 20 g/kg.
