ISO 11466 Extraction of Trace Elements in Soil Laboratory Testing Service Provided by Eurolab
The extraction of trace elements from soil is a critical laboratory testing service that helps determine the presence and concentration of various metals and metalloids in soil samples. This test is governed by several international and national standards, including ISO 11466, which provides guidelines for the extraction of trace elements from soils.
Overview of Relevant Standards
1. ISO 11466:1995(E) - Extraction of Trace Elements from Soils (Withdrawn) - This standard was published in 1995 and outlines a method for extracting trace elements from soil samples using aqua regia. Although withdrawn, it remains relevant as a reference document.
2. EN ISO 11466:2009 - Soil quality - Extraction of trace elements - Solvent mixture of nitric acid, hydrochloric acid, and water (Aquagen) - This European standard is based on the ISO 11466 method and provides a more detailed description of the extraction procedure.
3. ASTM D5184-13: Standard Test Method for Analysis of Lead in Soil - This American Society for Testing and Materials (ASTM) standard describes a method for analyzing lead in soil samples using aqua regia.
4. TSE ISO 11466:2009 - Toprak kalitesi - İzotopik birleştirme yöntemiyle iz elementlerin çıkarılması (Turkish Standard) - This Turkish standard is equivalent to EN ISO 11466 and outlines the extraction of trace elements from soil samples using aqua regia.
Legal and Regulatory Framework
The legal and regulatory framework surrounding ISO 11466 Extraction of Trace Elements in Soil testing varies depending on the country or region. However, many countries have adopted international standards as part of their national regulations. For example:
Standard Development Organizations
