Inorganic fertilizers and liming materials — Determination of specific elements — Determination of cadmium, chromium, copper, lead, nickel and zinc by inductively coupled plasma-atomic emission spectrometry (ICP-AES) after aqua regia dissolution prEN 16319 rev

Scope

This document specifies the method for the determination of the content of cadmium, chromium, copper, lead, nickel and zinc in fertilizers and liming materials using inductively coupled plasma atomic emission spectrometry (ICP-AES) after aqua regia dissolution. Limits of quantification are dependent on the sample matrix as well as on the instrument, but can roughly be expected to be 0,3 mg/kg for Cd and 1 mg/kg for Cr, Cu, Ni, Pb and Zn.
This document is applicable to the fertilizing products blends where a blend is a mix of at least two of the following components: fertilizers, liming materials, soil improvers, growing media, inhibitors, plant biostimulants and where the following category: inorganic fertilizers and liming materials is the highest % in the blend by mass or volume, or in the case of liquid form by dry mass. If inorganic fertilizers and liming materials is not the highest % in the blend, the European Standard for the highest % of the blend applies. In case a fertilizing product blend is composed of components in equal quantity, the user decides which standard to apply.
