The present work comprises the matrix effects study of the plant system (plant and soil) for macronutrients Ca and K with elevated levels of iron in the soil. The earlier derived matrix effect terms from fundamental relations of intensities of analyte and substrate elements with basic atomic and experimental setup parameters had led to iterative determination of enhanced elements rather than avoiding their enhancement. The relations also facilitated the evaluations of absorption for close Z interfering constituents (like Ca and K) in samples of a lot of particular category with interpolation of matrix terms with elemental amounts. The process has already been employed successfully for potato, radish, rice and maize plants. On similar lines, the observed prominent change in interpolation parameters for the plants in the present experiment serves as a tool to check the toxicity/contamination of the growing medium.
本研究工作包括对土壤中铁含量升高时植物系统（植物和土壤）中大量元素钙和钾的基体效应研究。早期从分析物和基体元素强度与基本原子及实验装置参数的基本关系中得出的基体效应项，导致对增强元素的反复测定，而不是避免其增强。这些关系还便于通过基体项与元素量的插值来评估许多特定类别的样品中相邻原子序数干扰成分（如钙和钾）的吸收情况。该方法已成功应用于马铃薯、萝卜、水稻和玉米植株。同样，在本实验中观察到的植物插值参数的显著变化，可作为检查生长介质毒性/污染的一种手段。
