Variation of heavy metal and micro and macro element concentrations of bread and durum wheats and their relationship in grain of Turkish wheat cultivars.

The 64 varieties displayed a large variation for all mineral elements, investigated Fe, Mn and Zn, ranging from 24.2 to 43.1 mg/kg, 27.6 to 64.8 mg/kg and 10.4 to 38.2 mg/kg, respectively. The mean Ca, K, Mg, Na, P and S concentrations in wheat rain varieties amounted to 378, 4,266, 1,183, 317, 3,513 and 1,542 mg/kg, respectively. Ca, K, Mg, Na, P and S contents of wheat varieties changed at the levels between 266 and 531 mg/kg, 3,029 and 5,566 mg/kg, 972 and 1,525 mg/kg, 277 and 368 mg/kg, 2,422 and 4,610 mg/kg and 1,241 to 2,052 mg/kg, respectively. The concentrations of Al, Cu, Fe, Mn and Zn of durum wheat samples were found at high levels. The mean Al, Cr, Mo, Ni, Cu, Fe, Mn and Zn concentrations in durum wheat varieties amounted to 10.93, 0.47, 0.72, 0.72, 5.37, 34.9, 37.28 and 20.88 mg/kg, respectively.
