Abstract: An incubation experiment was conducted to investigate the microbial biomass associated Cu in fourcontrasting soils to which an alkaline stabilised sewage sludge cake was applied. The organisms of sludge-amended and control soils were killed using ry-irradiation technique, and the aqueous and acid-extractable Cuconcentrations were determined. Addition of the sludge product increased significantly the concentration ofboth the aqueous and dilute HOAc-extractable Cu in all the irradiated soils compared to the non-sterilisedsludge/soil mixtures, but the increase was more pronounced in the dilute acid-extractable Cu, indicating thatthe Cu rendered extractable in water and dilute acetic acid by 7-irradiation existed in the both soil liquidand solid phases. The additional increase in extractable Cu following the biocidal treatment is likely to bedue to release of Cu from the same fraction of soil microbial biomass.
