IAQ (Indoor Air Quality) monitoring is very important to avoid any health issues, as well as when you notice some of the symptoms mentioned below. Office staff or households are not normally exposed to the same levels of dust, fumes and solvents as factory workers. However, office staff and households may still be exposed to pollutants causing bad indoor air quality and ill health. These pollutants may contain fumes from furniture, buildings and cleaning materials, ozone from laser printers, excess or low humidity, and gases from inadequately vented boilers or kitchen equipment.
Environmental Efficiency has a wide range of IAQ monitoring equipment that can measure a wide range of contaminants found in the office or at home. Following analysis of the results our experts can then advise on remedies to resolve the indoor air quality problem.
Symptoms of poor Indoor Air Quality
Poor IAQ & Indoor air pollution can lead to dryness and irritation of the eyes, nose, throat, headache and fatigue and dizziness and nausea.
People generally notice their symptoms after several hours and feel better after they have left the building. This would be a clear indication that the symptoms are related to IAQ.
Substances monitored for Temperature
Average, maximum and minimum temperature will be measured during the IAQ monitoring. High temperatures can cause discomfort.
Dust mite populations and fungal spores increase as humidity increases. Eye and respiratory problems increase at low humidity levels, which is a clear indoor air pollution aspect.
Carbon Monoxide (CO)
Sources of carbon monoxide are found in boilers, road traffic and leaking flues. Potential side effects of poor IAQ include headache, dizziness, vomiting, and nausea and death.
Carbon Dioxide (CO2).
Carbon dioxide is a by-product of human activity as this is breathed out. High levels could indicate a lack of ventilation. In high than normal concentrations, it may make some people feel drowsy and give the lungs a stuffy feeling.
Nitrogen dioxide (NO2)
The main side effects include airway inflammation in healthy people and increased respiratory symptoms in people with asthma.
Hydrogen Sulphide (H2S)
Potential sources of hydrogen sulphide are to found in sewers. Exposure to low levels can irritate the eyes, cause a cough or sore throat, shortness of breath, and fluid accumulation in the lungs.
Potential sources of formaldehyde come from furniture, building products, especially some types of insulation. Potential side effects of this poor IAQ are eye, nose, and throat irritation.
Toluene, Benzene and Xylene
These substances are found mainly in paints, cleaning products, detergents and oil spills. Side effects of this indoor air pollution include tiredness, confusion, weakness, drunken-type actions, memory loss, nausea, loss of appetite, irregular heartbeats, tremors and confusion and hearing and colour vision loss
Ozone is produced by printers, photocopies and UV lamps. The most important side effects of this bad IAQ are: chest pain, coughing, throat irritation, and congestion. It can worsen bronchitis, emphysema, and asthma.
Other substances can be added as required but the above is suitable for 95% of IAQ issues.
