Macro and Micronutrients Assessment in Transgenic an Non-Transgenic Soybean Seeds by Inductively Coupled Plasma Optical Emission Spectroscopy

Abstract

The main goal of this work was to evaluate macro (Ca and P) and micro (Cu, Fe and Zn) nutrients in transgenic (T) and non-transgenic (NT) soybean seeds by inductively coupled plasma optical emission spectroscopy. A multi-elemental method was developed, using a certified reference material (tomato leaves 1573a) for checking the accuracy, and rhodium as internal standard. The method was efficient to determine the analytes, allowing the comparison among different soybean seeds samples.
