Winter has well and truly set in and the chances are that indoor, rather than outdoor, air pollution is now the primary threat to our health, particularly if you suffer from allergies, asthma or other respiratory conditions. So, how do I clean the air in my home? A new paper from the Parliamentary Office of Science and Technology (POST) reviews the state of indoor air pollution in the UK.
This study points out that while it's well known that outdoor air pollution is harmful to health, most people are not aware of the severe impact that indoor air pollution can have on your health. Indoor air pollution in your home can come from:
Some of the indoor pollutants from these sources that can accumulate in your home include nitrogen oxides, carbon monoxide, particulate matter, radon, tobacco smoke, allergens like mould and house dust mite and volatile organic compounds. While there is plenty of scientific evidence for the health impacts of carbon monoxide and radon, lack of research and monitoring mean that less is known about the dangers of exposure to other indoor pollutants.
Does the POST paper highlight what we do know about some key indoor pollutants - a starting point for further research perhaps? Here's a summary.....
Volatile organic compounds irritate the lungs, with children being especially vulnerable. They include both natural and synthetic chemicals like formaldehyde, coming from several sources including construction products, cleaning products, air fresheners, paints and electrical goods.
Clearly, exposure to indoor air pollution may pose a substantial health risk. So how can UK regulation and policy be improved to deal with the threat? The POST paper has some thought-provoking suggestions....(to be continued)
