...Huan Liu; Xiancai Lu; Xiangjie Cui; Lijuan Zhang; Ting-Shan Chan Abstract Hydroxyapatite (HAp) has been widely used to remove cadmium (Cd) in contaminated water and soils via Cd-Ca substitution. The Cd incorporation into HAp affects its structure; however, the detailed mechanism remains unclear...

... for quantifying the timing and severity of deoxygenation and nutrient cycling in Earth's past. The resilience of isotopic data to thermal alteration of the host sediments over millions of years of burial is, however, largely unknown. We present molybdenum, uranium, cadmium, and zinc stable-isotope data from two...

...–Mn oxide fractions for Mo in soils reached 14.2, 5.3 and 24.4%, respectively. Cadmium existed in soils mainly in the exchangeable (6.3%), carbonate (25.7%) and Fe–Mn oxide (16.7%) fractions. The results indicated that Mo and Cd had a potential ecological risk to the environment. Contrary to the other...
