| Abstract: | Land disposal of fly ash(FA) and sewage sludge(SS) is a major problem due largely to their potentially harmful constituents.Previous studies,however,showed that the combined use of FA and SS might help reduce the associated pollution potential.In this paper,pot-planting experiments were performed to evaluate the effects on the plant growth and heavy metal accumulation characteristics in the plants when soils were amended with the mixture of FA and SS.The results showed that the application of FA and SS was ... |
