Comparison and harmonization of measuring methods for air contaminants in the working environment.

The objective of this work was to demonstrate that the measurement of air contaminants in the workplace requires a special approach.
Decisive in carrying out the measuring task is the quality of the sampling strategy, including selection of the appropriate measuring method.
Methods developed at a national level may be more suitable for this purpose than methods described in international standards.
Measurements of air contaminants in the workplace should always be the basis for the prevention and control of occupational hazards.
Such measurements, therefore, are also an essential element of risk assessment.
Industrial processes and chemical agents are myriad.
Each manufacturing stage may apply different conditions (e.g., batch production or continuous process, temperature, pressure) and agents (e.g. a wide variety of chemical substances) : In each of these stages, different job functions may be necessary and may be subject to different exposure conditions.
Distance from emission sources and physical parameters, such as rates of release, air current, meteorological variations, also have a profound influence.
The measuring task in the workplace is quite different in comparison to many others (e.g., blood or soil sample analysis).
Firstly, the selection of sampling time and sampling location are crucial steps in air analysis.
Transportation and storage of the samples, may however, also influence measuring results ; interlaboratory tests show the existing problems. (...)
