Standard methods for elemental speciation analysis have been developed, validated and approved by standardization bodies for special application fields.
The development of standard methods (mostly including standard operating procedures, SOPs) is demanding with respect to time and resources and therefore will be done by standardization bodies only when legislation or economical requirements call for them.
For the following elements and their species such standard methods have been created:
Besides the information given under the above mentioned chapters, our Link database gives access to analytical methods for all elements and their species.
Further information can be found in databases provided by the standardization organizations, such as:
GESTIS-Analytical methods for chemical substances
This database contains validated lists of methods from various EU member states described as suitable for the
analysis of chemical agents at workplaces. The priority of substances covered here was defined in line with their
relevance to workplace health.
National Institute for Occupational Health and Safety (NIOSH) Manual of Analytical Methods (NMAM)
A collection of methods for sampling and analysis of contaminants in
workplace air, and in the blood and urine of workers who are
occupationally exposed. These methods have been developed or adapted by
NIOSH or its partners and have been evaluated according to established
experimental protocols and performance criteria. NMAM also includes
chapters on quality assurance, sampling, portable instrumentation.
NEMI - National Environmental Methods Index
A searchable database of environmental analytical methods
OECD Guidelines for the Testing of Chemicals
Internationally agreed test methods to determine the safety of chemicals
and chemical preparations, including pesticides and industrial
Occupational Safety and Health Administration (OSHA)
OSHA provides an alphabetical list of chemicals that have either a
validated or partially validated OSHA method. Some chemicals may be
listed by their common synonym. The index includes the method number,
validation status, CAS number, analytical instrument and sampling
U.S. Environmental Protection Agency (EPA) - Clean Water Act Analytical Methods
The analytical methods promulgated under Clean Water Act section 304(h)
are sometimes referred to as the "304(h)" or "Part 136" methods. The
methods measure chemical and biological pollutants in media, such as
wastewater, ambient water, sediment, and biosolids (sewage sludge).
These various CWA methods are tested in a variety of labs and matrices.
U.S. Environmental Protection Agency (EPA) - Other Clean Water Act Test Methods: Chemical - Not Approved Under 40 CFR Part 136
In addition to developing and approving methods for use in compliance monitoring, EPA may develop methods to support studies of specific industries (e.g., the Effluent Guidelines program) or for use in broad national surveys. If such studies or surveys lead to regulatory limits of new contaminants, EPA approves the applicable methods for nationwide or industry-specific use through rulemaking which includes an opportunity for public comment.
