Indoor Air Pollution measurements

What will be measured in the home?

In our study, some of the air pollutants associated with burning fuels and tobacco smoke will be measured. They include pollutants such as  particulate matter, noxious gases and biological material.

Particulate matter

Particulates of various sizes are released when we burn any product. We can see some of the larger particles such as soot or ash, but most of the smaller particles are invisible to the naked eye. It is these tiny particles which we are interested in measuring.

Noxious Gases

Noxious gases such as carbon monoxide and nitrous oxides are released during the burning of fossil fuels. Carbon monoxide is a colourless odourless gas which is formed when fuel is not completely burned.

Biological Material

A biological toxin called endotoxin is found in the cell wall of certain types of bacteria. Endotoxin can be found in the air in most homes, however higher levels are found where fossil fuels are used or in rural homes especially those on farms or which have pets.

How will we measure air pollution in homes?

If you agree to participate, a member of the project team will be in contact  to agree a suitable day for them to visit your home and perform the measurements. A trained researcher will place devices in your home to measure a number of air pollutants. They will use small, discrete, specialist equipment which should not interfere with the day to day activities in your home. You will be asked to complete a short questionnaire, to provide brief details of fuel use and smoking within your home over the measurement period. It is estimated that the researcher will be present in your home for around 30 minutes on a total of three occasions over a 21 day period to set up and collect the equipment and the questionnaire.
