SOURCES OF INDOOR CHEMICAL POLLUTANTS

 

Air Quality Guidelines

 

 

You should be aware that there is not any legislation for pollutants in indoor environments which are not workplaces. So, the World Health Organization has proposed air quality guidelines for Europe that can be apply to indoor environments such as accommodations. The values refer generally to the exposures for which no opposite effect on the human health was observed.

These guidelines are a help for the decisions about national or international legislation.

But the problem is that the values are for pollutants taken one by one. They do not take into account the additive, synergic or opposing effects that can occur between pollutants.

 

So here you can read the air quality guidelines from the WHO. 

 

  • ŘFormaldehyde : 100 μg/m3 (30 min) or 40 μg/m3 (1 year)
 
  • Styrene : 70 μg/m3 (30 min) or 260 μg/m3 (1 week)
 
  • Toluene : 1 mg/m3 (30 min) or 260 μg/m3 (1 week)
 
  • Tetrachloroethylene : 8 mg/m3 (30 min)
 
  • NO2 : 200 μg/m3 (1h) or 40 μg/m3 (1 year)
 
  • Lead : 0,5 μg/m3 (1 year)
 
  • O3 : 100 μg/m3 (8h)or 180 μg/m3 (1h)
 
  • CO : 100 mg/m3 (15 min), 60 mg/m3 (30 min), 30 mg/m3 (1h), 10 mg/m3 (8h)
 
  • PM 10: 50 μg/m3 (1 day) or 20 μg/m3 (1 year)
 
  • PM 2,5 : 25 μg/m3 (1 day) or 10 μg/m3 (1 year)
