Air Quality Testing

Indoor Air Testing
We use powerful gas analysers to measure the exact concentration of toxic and cancerous gasses in homes and local businesses.
While some indoor air pollutants come from the outside, most are released inside the home through the use of cleaning products, air fresheners and new furniture.
Outdoor Air Mapping
We monitor dust (PM10/2.5/1) and chemical contaminants (NOx, O3, VOCs, SO2, CO) in the air and produce 2D maps within minutes.
Particulate matter (PM10/2.5/1) or Dust
Dust consists of small airborne particles that can’t always be seen by the human eye. Airborne particulate matter varies widely in its physical and chemical composition, source and particle size. PM10 particles (<10 µm) and PM2.5 particles (<2.5 µm) are of major current concern, as they are small enough to penetrate deep into the lungs and so potentially pose significant health risks. Larger particles meanwhile, are not readily inhaled, and are removed relatively efficiently from the air. The principal sources of airborne PM10 and PM2.5 are road traffic emissions, construction, fires, industries and chemical plants.
We test for PM10, PM2.5 and PM1, then send you a map for clear visualisation.
SO2, VOC, NO2, O3 and CO
These chemicals can have an adverse effect on people health at certain concentrations and should be carefully monitored.
We provide concentration maps of your outdoor areas for easy visualisation.
Nitrogen oxides (NOx)
Nitrogen oxide is a term used to describe a mixture of nitric oxide (NO) and nitrogen dioxide (NO2). NOx is emitted when fuel is being burned in transport, industrial processes and power generation. Nitrogen dioxide can irritate the lungs and lower resistance to respiratory infections. Continued or frequent exposure may cause increased incidence of acute respiratory illness in children.
Ozone (O3)
Ground-level ozone, unlike other pollutants mentioned, is not emitted directly into the atmosphere, but is a secondary pollutant produced by reaction between nitrogen dioxide (NO2), hydrocarbons and sunlight. Ozone irritates the airways of the lungs, increasing the symptoms of those suffering from asthma and lung diseases.
Volatile organic compounds (VOC)
Because there are many hundreds of different compounds, VOC display a wide range of properties. Some, such as benzene, are carcinogenic; some are toxic and others harmless to health. Possible chronic health effects include central nervous system disorders, liver and kidney damage, reproductive disorders, and birth defects.
Sulphur dioxide (SO2)
The majority of the sulphur dioxide emitted to the air is from industries, and the contribution from transport sources is small (shipping being an exception). Exposure to SO2 can damage health by its action on the bronchial system. Tightness in the chest and coughing occur at high levels, and lung function of asthmatics may be impaired to the extent that medical help is required.
Carbon monoxide (CO)
Carbon monoxide is produced by the incomplete burning of materials which contain carbon, including most transport fuels. Carbon monoxide is toxic, acting by reaction with haemoglobin and reducing its capacity for oxygen transport in the blood.
