Abstract

Solubilities of heavy metals in soils are suggested to be affected by changes in soil adsorption capacities .. This research evaluated the changes in lead and cadmium solubilities in an Andisol treated with lime and/or cassava-leaf compost. Soil sample was treated with lime at rates ranging from O to 10 ton CaCO3 ha•-l and/or cassava-leaf compost at rates ranging from O to 20 ton ha-1. A standard solution containing Pb and Cd or industrial waste was also added into soil mixture. After an incubation for 4 weeks at 40% moisture content and room temperature, the soluble Pb and Cd and soil pH of soil mixture were determined. Unlike the changes in the soluble Cu and Zn previously reported, the solubility of Pb was found to decrease with lime and slightly decrease with compost addition, particularly at lime rates of < 5 ton ha-1, in negative correlations with the changes in soil pH. The soluble Cd also decreased with lime but was not affected by compost additions. Addition of industrial waste did not increase the soluble Pb and Cd but changed the patterns of lime and/or compost effects. Lime and/or compost treatments tended to increase the soluble Pb and Cd in waste treated soils. Depending on soil treatments, Andisol immobilized 75.5-94.3% Pb and 34.3-48.9% Cd of the added standard.
