title: Element content analysis by WDXRF in pistachios grown under organic and conventional farming regimes for human nutrition and health.
abstract: In this investigation, the elemental composition of various Antep pistachios (Pistacia vera L.) samples was determined using a sensitive method called wavelength dispersive x-ray fluorescence (WDXRF). A total of 27 elements, such as Al, As, Bi, Ca, Cd, Cu, Fe, Mn, Ni, P, S, Sr, Zn, Cl, Pb, K, Mg, Na, Ba, Rb, Si, Br, Sn, Au, La, Ti and Zr, were determined in pistachios samples (n = 10) grown under organic and conventional farming regimes. The obtained results from each group were analyzed statistically using SPSS statistic program. It was observed that the concentration and peak intensity values of Ca, Fe, Mn, P, Mg, Cl, Na and K elements were higher in the pistachios samples grown under organic farming regime. Similarly, Al was found in higher level in the samples grown under conventional farming regime. As, Bi, Cd, Pb, Ti, La, Sn and Zr contents were measured. Their contents were below the detection limits. Our findings clearly revealed that organic pistachios are likely to have higher nutritional mineral content. The pistachios samples grown under conventional farming regime could contain harmful metals like Al that might damage various systems and/or organs of humans and animals.
