本文试验研究了几种有机物质对冶炼厂附近污染土壤中铜形态及其活性的影响.结果表明,有机物质添加后对土壤铜化学形态与活性的影响进程较为迅速,半个月内就有明显的表现:不同类型有机物质都对土壤铜的化学活性有控制作用,但控制效果因有机物质种类而异,且与有机物质在土壤中腐解转化有关.

Upon addition of organic materials to copper contaminated soil, fractionation and availability of copper were significantly affected after half month incubation. Compared with non - organic treatment, the fractions of soil copper changed. The fractions of WBO - cu, and OXMn - Cu decreased sharply, while SBO - Cu and AmoreFe - Cu increased significantly. The chemical available copper extracted with 2.5% acetic acid solution decreased by 20 to 40 % in all organic treatments. However, the effect depends on the properties of organic materials. For instance, green manure led to an increase in Exch - Cu and activation of chemical available copper in the early stage of incubation compared with compost and peat.
