Workers in factories, manufacturing enterprises and office environments are exposed to indoor air pollutants such as dust, gas and steam that occur during the day. If the necessary precautions are not taken, it is inevitable that the employees will suffer from this. There can be a wide variety of air pollutants. These include volatile organic and inorganic compounds and respirable dust particles.

The first thing to do to protect workers in such environments is to determine the concentrations of pollutants that are likely to be present in the environment. However, prior to this, it is necessary to determine which pollutants are present in the working environment. For example, if chemicals are used in the production facilities of a factory, their properties should be examined. In an office environment, oscillations arising from the computer, photocopy, printer, and even furniture and upholstery used should be identified.

However, once potential contaminants have been identified, their ambient concentrations and personal exposure values ​​should be measured. Exposure measurements in ambient air are carried out by laboratories authorized by national or international accreditation bodies. The validity of the reports to be issued regarding the results of these measurements within the scope of the imission measurements depends on this.

The laboratories carry out the excuse measurements on the basis of Occupational Exposure Limit Values ​​given in the annex of the Regulation on Health and Safety Measures in Working with Chemical Substances issued by the Ministry of Labor and Social Security.

There are also many national and international standards to consider. Here are just a few of them:

• TS 2361 Air pollution measurement methods Determination of the amount of suspended substances in the air
• TS ISO 8518 Workplace air - Determination of lead and lead compounds in grain - Flame or electrothermal atomic absorption spectrometric method
• TS ISO 16000-5 Indoor air - Part 5: Sampling strategy of volatile organic compounds
• NIOSH 5026 Oil mist, mineral (oil vapors)
• NIOSH 6009 Mercury
• NIOSH 6010 Hydrogen Cyanide (hydrogen cyanide)
• NIOSH 6601 Oxygen
• NIOSH 6604 Carbon Monoxide
• NIOSH 7300 Elements by ICP (heavy metals)
