Phosphate fertilisers are commonly used in agricultural lands to supply phosphorus nutrients for enhancing quantity and quality of crop products around the world. According to the literature, phosphorus-fertilisers may contain considerable amounts of uranium varying from less than 10 to more than 360 mg kg-1, and uranium can be loaded onto soils from 7 to 23 g ha-1 yr-1 with applying of 22 kg P ha-1 yr-1 (50 kg P2O5 ha-1) from various phosphorus-containing fertilisers. With increasing uranium content and concentration in soil, uranium concentration may increase in plant tissues, animal bodies, and the human body in the long run; it can cause damage to health of human and animals mainly based on its chemical toxicities as a heavy element. Total amount of uranium, uranium-to-phosphorus ratio, and uranium solubility and transferability vary in different P-containing fertilisers.weiterlesen
