Cd in mineral phosphate fertilizers depends on phosphate rocks (apatite and phosphorite), by far the most important phosphorus-bearing raw material used in the fertilizer industry [21]. Different types of phosphate rocks have different levels of Cd, based on the type of ore (igneous or sedimentary) and geographic provenance.
