Plant biostimulants - Determination of specific elements - Part 1: Digestion by aqua regia for subsequent determination of elements

This document specifies the method for the digestion of different plant biostimulants with aqua regia to enable a subsequent determination of arsenic (As), cadmium (Cd), copper (Cu), chromium (Cr), mercury (Hg), nickel (Ni), lead (Pb) and zinc (Zn). The method can be also applied for determination of other elements. The method is applicable for all solid and/or liquid plant biostimulants.
This document is also applicable to the blends of fertilizing products where plant biostimulants are the main part of the blend. Otherwise, the Technical Specification for the main part of the blend applies.
The extracts are suitable for analysis using CEN/TS 17701-2 (ICP-AES) and CEN/TS 17701-3 (Hg analysis).
NOTE   Alternatively, inductively coupled plasma mass spectrometry (ICP-MS) can be used for the measurement if the user proves that the method gives the same results.

Pflanzen-Biostimulanzien - Bestimmung spezifischer Elemente - Teil 1: Aufschluss durch Königswasser zur anschließenden Bestimmung der Elemente

Dieses Dokument legt das Verfahren für den Aufschluss verschiedener Pflanzen-Biostimulanzien mit Königswasser fest, um eine anschließende Bestimmung von Arsen (As), Cadmium (Cd), Kupfer (Cu), Chrom (Cr), Quecksilber (Hg), Nickel (Ni), Blei (Pb) und Zink (Zn) zu ermöglichen. Das Verfahren kann auch für die Bestimmung anderer Elemente verwendet werden. Das Verfahren ist für alle festen und/oder flüssigen Pflanzen-Biostimulanzien anwendbar.
Dieses Dokument ist auch für die Mischungen von Düngeprodukten, in denen die Pflanzen-Biostimulanzien der Hauptbestandteil der Mischung sind, anwendbar. Andernfalls gilt die Technische Spezifikation für den Hauptbestandteil der Mischung.
Die Extrakte sind für die Analyse nach CEN/TS 17701 2 (ICP AES) und CEN/TS 17701 3 (Quecksilber-Analyse) geeignet.
ANMERKUNG   Alternativ kann die Massenspektrometrie mit induktiv gekoppeltem Plasma (ICP MS) für die Messung genutzt werden, sofern der Anwender nachweist, dass das Verfahren zu den gleichen Ergebnissen führt.

Biostimulants des végétaux - Dosage des éléments spécifiques - Partie 1 : Digestion à l'eau régale pour le dosage ultérieur des éléments

Le présent document spécifie la méthode pour la digestion de différents biostimulants des végétaux à l’eau régale pour permettre le dosage ultérieur de l’arsenic (As), du cadmium (Cd), du cuivre (Cu), du chrome (Cr), du mercure (Hg), du nickel (Ni), du plomb (Pb) et du zinc (Zn). Cette méthode peut aussi être appliquée pour le dosage d’autres éléments. Cette méthode est applicable à tous les biostimulants des végétaux solides et/ou liquides.
Le présent document est également applicable aux mélanges de fertilisants dont la majeure partie est constituée de biostimulants des végétaux. Dans le cas contraire, la Spécification technique relative au constituant principal du mélange s’applique.
Les extraits conviennent pour une analyse selon la CEN/TS 17701-2 (ICP-AES) et la CEN/TS 17701-3 (analyse du Hg).
NOTE   Il est également possible d’utiliser la spectrométrie de masse avec plasma à couplage inductif (ICP-MS) pour la mesure, si l’utilisateur prouve que la méthode conduit aux mêmes résultats.

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 5 June 2019 laying down rules on the making available on the market of

EU fertilising products (“FPR” or “Fertilising Products Regulation”).

This request, presented as SR M/564, also contributes to the Communication on “Innovating for

Sustainable Growth: A Bio economy for Europe”. The Working Group 4 “Other safety parameters”, was

created to develop a work program as part of this Request. The technical committee CEN/TC 455 ‘Plant

Biostimulants’ was established to carry out the work program 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 improving 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.

Aqua regia is applied to digest different matrices for the subsequent 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). CEN/TC 260 also prepared a standard for extraction of a total

micronutrients content in fertilizers using aqua regia. CEN/TC 223 published a standard for a similar

procedure for soil improvers and growing media. Wide use of the aqua regia digestion, availability of the

instruments and the possibility to merge the standards for different matrices in future, were the main

reasons for also applying this method of digestion for plant biostimulants. A simple pre-concentration

procedure is a part of this document to also cover the digestion of liquid samples with low dry matter

content in the case that the measurement method is not sufficiently sensitive. An Annex A describes in

detail the calculation of the initial sample weight to be taken for the pre-concentration step to achieve

concentrations of the individual elements above the limit of quantification.

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.

1 Scope

This document specifies the procedure for the digestion of different plant biostimulants with aqua regia

to enable a subsequent determination of arsenic (As), cadmium (Cd), copper (Cu), chromium (Cr),

mercury (Hg), nickel (Ni), lead (Pb) and zinc (Zn). The procedure can be also applied for determination

of other elements. The procedure is applicable for all solid and/or liquid plant biostimulants.

This document is also applicable to the blends of fertilizing products where plant biostimulants are the

main part of the blend. Otherwise, the Technical Specification for the main part of the blend applies.

The extracts are suitable for analysis using CEN/TS 17701-2 (ICP-AES) and CEN/TS 17701-3 (Hg

analysis).
