International platforms for researching published methods for measuring hazardous substances

Origin of the methods

Only methods published in compendia of methods for atmospheric measurements at the workplace are considered. The following are not listed:

• Methods designed solely for static (area) sampling:
  Methods for atmospheric measurement at the workplace must be designed for measurement of personal exposure. The sampling system must be located as close as possible to the employee's breathing zone. Consequently, only methods employing personal air samplers are listed.
• Methods developed for the ambient air:
  The environmental conditions and substance concentrations in the ambient air may differ widely from those at the workplace, and are not comparable. For this reason, the conditions under which atmospheric workplace measurements are performed differ from those for the ambient air. Indoor atmospheric measurements usually involve static sampling methods with a high air flow.
• Methods developed by companies, without review by an independent group:
  Methods stated in company information are not normally assessed against EN 482, and refer to the company's own products. They do not refer to products from other companies with similar performance.

The acknowledged sources are listed in the table. In the interests of brevity, the publishers of the methods are stated only in abbreviated form in the lists of methods in the database.
