title: Studies on mineral nutrition and safety of wild rice (Oryza L.).
abstract: Mineral element contents of five wild rice were analyzed, including mineral nutrient elements such as phosphorus (P), potassium (K), calcium (Ca), sodium (Na), magnesium (Mg), iron (Fe), zinc (Zn), copper (Cu), manganese (Mn) and selenium (Se), and the potential toxic elements arsenic (As), mercury (Hg), lead (Pb) and cadmium (Cd). The results showed that the contents of K, Mg, Fe, Zn, Cu, Mn and Se in five wild rice materials were much higher than the cultivate variety Zhou 903 in both brown and milled rice. Wild rice also had lower potential toxic element contents of Hg, Pb and Cd compared with Zhou 903 in brown rice and milled rice, respectively. Among five wild rice samples, WR-3 from Uganda had the highest level of P, K, Ca, Na, Mg, Fe, Zn, Mn and Se, and the lowest contents of Hg, Pb and Cd.
