Land Application of Wastes: An Educational Program. Potentially Toxic Elements - Module 11.
Clarkson, W. W.; And Others
Five elements are identified as being potentially hazardous in this module. These are boron, cadmium, copper, molybdenum, and nickel. The hazards to plants and animals posed by these elements are discussed in some detail. The sources of toxic elements in sewage and the factors that effect the uptake of toxic elements by sewage sludge are also discussed. Methods of computing allowable sludge loading rates to land are discussed and compared. Sludge loading on the basis of potentially toxic elements is compared to the nitrogen basis and the specific limitations which cadmium may exert. (BB)
