Cadmium sorption was examined in three soils that were unamended, freshly amended, or preconditioned with gamma-irradiated sewage sludge. Metal sorption in the same soils treated with a CaCl/sub 2/-extract of the sludge was also studied. Cadmium sorption was greatest in the unamended soils, less in soils preconditioned with sludge, and least in the freshly amended soils and sludge-extract-treated soils. The authors attempted to explain the treatment effects on the basis of reduced free metal ion activity, but the explanations were not adequate. Despite the reduction in metal retention effected by various treatments, cadmium mobility was very limited. Short- or long-term leaching studies showed cadmium movement to be limited to 1 or 2 m below the zone of sludge (/sup 109/Cd) incorporation. Cadmium mobility is expected to be very limited in calcareous soils, regardless of sludge treatments. 24 references, 1 figure, 5 tables.
