Kurzbeschreibung des Verlags

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.
