Particulate Monitoring
PM 10 particles are less than 10 microns
in diameter and are easily inhaled into the lungs. The
main sources vary significantly between regions.
Gas measurement
Sulphur dioxide (SO 2 )
Sulphur dioxide (SO 2 ) is a colourless
gas, which forms sulphuric acid when combined with water.
Sources include the combustion of fossil fuels containing
sulphur, eg. coal and diesel, and industrial processes
such as fertiliser manufacturing, aluminium smelting
and steel making. Sulphur dioxide also results from
natural sources such as geothermal activity.
Nitrogen dioxide (NO 2 )
Nitrogen dioxide (NO 2 ) is a reddish-brown
gas. It is not usually released directly into the air
but forms when nitrogen oxide (NO) and other nitrogen
oxides (NOx) react with other chemicals. Nitrogen oxide
is released from combustion, especially of petrol in
cars. It also comes from the production of nitric acid,
welding, and explosives. Natural sources of nitrogen
oxides include volcanoes and bacteria.
Metals
POLLUCON is accredited to perform metals
analysis on filters used in air monitoring. The filters
are the same as those used in the particulate test,
and one filter can be used for both tests.
Sick Building Syndrome
Sick building syndrome (SBS) is a situation
in which occupants of a building experience acute health
effects that seem to be linked to time spent in a building,
but no specific illness or cause can be identified.
The complaints may be localised in a particular room
or zone, or may be widespread throughout the building.
POLLUCON samplers have a set of purpose built equipment
to check for SBS. The analyses we perform provide building
owners with a comprehensive air-quality report that
can identify problems within the building. Professional
treatment companies can then take these reports and
provide solutions to any problems that are found. Available
tests include:
- Particulate Matter
- Yeast and Moulds
- Bacteria
- Physical parameters
- Carbon monoxide
Other air monitoring tests
POLLUCON offers a wide range of specialized air quality
tests which utilize the analytical capability of our
laboratory facility. The tests include any water-soluble
compound that can be eluted from a filter used to collect
air samples. The tests include but are not necessarily
limited to the following:
- Anions and cations such as fluoride and ammonia
- Total Reduced Sulphur
- Legionella
