The sequential extraction procedure of the Community Bureau of Reference (BCR) was applied to investigate the mobility of potentially toxic elements (As, Cd, Cr, and Pb) and nutrients (P, Ca, Mg, Cu, Fe, Mn, and Zn) in a multinutrient mineral fertilizer based on phosphate rocks supplemented with 10% (w w–1) micronutrient mixture (raw material used as a micronutrient source). For both samples, As and Cd were more mobile, whereas Cr remained in the solid residue. A higher mobility of Pb was observed in the micronutrient mixture; however, the high concentration of P (8.3% w w–1) in the fertilizer could have decreased Pb mobility as a result of Pb3(PO4)2 formation. The nutrients had great mobility, except Fe, which remained almost totally in the residual fraction in both samples. X-ray diffraction, scanning electron microscopy, and energy dispersive spectroscopy analyses of solid residues showed that the ways in which elements were distributed in the sample particles could affect their mobility.

参考协议社区局评估矿物肥料中营养物质和有毒元素的流动性的分析能力
应用社区参考局（BCR）的顺序提取程序来研究潜在有毒元素（As，Cd，Cr和Pb）和养分（P，Ca，Mg，Cu，Fe，Mn和Zn的迁移率） ），在以磷矿石为基础的多营养矿物肥料中，添加了10％（ww –1）微量营养素混合物（原料用作微量营养素来源）。对于这两个样品，As和Cd的流动性更高，而Cr保留在固体残留物中。在微量营养素混合物中观察到较高的Pb迁移率；但是，由于Pb 3（PO 4）2的存在，肥料中高浓度的P（8.3％ww –1）可能会降低Pb的迁移率。编队。除铁外，所有养分均具有很大的迁移率，但铁几乎完全保留在两个样品的残留部分中。固体残留物的X射线衍射，扫描电子显微镜和能谱分析表明，元素在样品颗粒中的分布方式可能会影响其迁移率。
