Air Quality Monitoring

Air quality monitoring and testing is an important part of environmental safety. The Canadian Clean Air Act has established standards for maximum allowable concentrations of pollutants in the air also known as the threshold limit values (TLVs).Air quality measurements is either accomplished by continuous air monitoring instruments or through air sampling- the collection of a mass of pollutant for future in deep laboratory analysis. 

The six most common air pollutants also called “criteria pollutants” by US-EPA include: Ozone, particulate matter, carbon monoxide, nitrogen oxides, sulfur dioxide and Lead. Other airborne pollutants such as benzene, arsenic, chlorine, ammonia and hydrogen sulfide are also strictly regulated for their carcinogenic and other health related effects, even at very low concentrations. 

Indoor and Ambient air pollution is a major concern in many cities around the globe, both in the industrialized and developing world causing damage to the natural environment and disease or death to humans and other living species. Despite legislations and regulations, most industrial and residential buildings don’t have the proper equipments to monitor air quality and meet regulatory requirements.

When air-sampling, the choice of a sampling technique and quantification method depend greatly upon the properties of the pollutant to be collected which can be gaseous or particulate matter. The collection of a representative sample of contaminated air requires a great deal of attention to a number of parameters such as temperature, pressure, humidity, the volume of samples, as well as the timing.
