Plant biostimulants - Determination of specific elements - Part 2: Determination of total content of Cd, Pb, Ni, As, Cr, Cu and Zn

This document specifies a method for the determination of total contents of arsenic (As), cadmium (Cd), copper (Cu), chromium (Cr), lead (Pb), nickel (Ni) and zinc (Zn) in aqua regia plant biostimulant digests using inductively coupled plasma-atomic emission spectrometry (ICP-AES).
This document is applicable to the blends of fertilizing products where a blend is a mix of at least two of the following component EU fertilizing products categories: Fertilizers, Liming Materials, Soil Improvers, Growing Media, Inhibitors, Plant Biostimulants, and where the following category Plant Biostimulants is the highest % in the blend by mass or volume, or in the case of liquid form by dry mass. If Plant Biostimulants is not the highest % in the blend, the European Standard for the highest % of the blend applies. In case a blend of fertilizing products is composed of components in equal quantity or in case the component EU fertilising products used for the blend have identical formulations, the user decides which standard to apply.
This method is applicable to aqua regia digests prepared according to EN 17701-1:—1. The method can be used for the determination of other elements, provided the user has verified the applicability.
NOTE   Alternatively, inductively coupled plasma mass spectrometry (ICP-MS) can be used for the determination of the elements in the aqua regia digests if the user proves that the method gives the same results.

Introduction
This document was prepared by the experts of CEN/TC 455 “Plant biostimulants”. The European
Committee for Standardization (CEN) was requested by the European Commission (EC) to draft
European standards or European standardization deliverables to support the implementation of
Regulation (EU) 2019/1009 of the European Parliament and of the Council of 5 June 2019 laying down
rules on the making available on the market of EU fertilising products (“FPR” or “Fertilising Products
Regulation”).
This standardization request, presented as M/564 and M/564/Amd1, also contributes to the
Communication on “Innovating for Sustainable Growth: A Bio economy for Europe”. Working Group 4
“Other safety parameters” was created to develop a work programme as part of this standardization
request. Technical Committee CEN/TC 455 “Plant biostimulants” was established to carry out the work
programme that will prepare a series of standards. The interest in biostimulants has increased
significantly in Europe as a valuable tool to use in agriculture. Standardization was identified as having
an important role in order to promote the use of biostimulants. The work of CEN/TC 455 seeks to improve
the reliability of the supply chain, thereby boosting the confidence of farmers, industry, and consumers
in biostimulants, and will promote and support commercialisation of the European biostimulant
industry.
The preparation of this document is based on a standardization request to CEN by the European
Commission and the European Free Trade Association (Mandate M/564) concerning the modernization
of methods of analysis of fertilizers in the framework of Regulation (EU) 2019/1009 of the European
Parliament and of the Council.
This document is part of a modular approach and concerns the analytical measurement step. “Modular”
means that a test standard concerns a specific step in assessing a property and not the whole chain of
measurements. Aqua regia digestion followed by inductively coupled plasma atomic emission
spectrometry is widely used for determination of many elements. For example, a multi-matrix standard
for aqua regia extraction of soils, sludges and biowaste was prepared by CEN/TC 444. A similar procedure
was applied for determination of aqua regia extractable contents of arsenic, mercury, cadmium,
chromium, nickel and lead in fertilizers and liming materials (standard prepared by CEN/TC 260).
Inductively coupled plasma atomic emission spectrometry (ICP-AES) is nowadays widely used and
a well-established method in many laboratories.
The inter-laboratory study reflects the final statistical characteristics of the method for the determination
of the specific elements in aqua regia digests including both, the digestion and the measurement steps.
WARNING — Persons using this document should be familiar with usual laboratory practice. This
document does not purport to address all of the safety issues, if any, associated with its use. It is the
responsibility of the user to establish appropriate health and safety practices and to ensure compliance
with any national regulatory conditions.
IMPORTANT — It is absolutely essential that tests conducted according to this document are carried out
by suitably trained staff.
