This study was restricted to an attempt to determine redistribution pathways of cadmium and other selected heavy metals in commercial phosphate fertilizer processing and to determine if any of the several processing steps result in a significant concentration of dilution effect in either final products or was materials. Thermal (furnace) phosphoric acid and waste materials such as sewage sludge were not included in the study.
