A major report from the Royal College of Physicians and the Royal College of Paediatrics and Child Health has laid bare the risks to public health from air pollution, both outdoors and in domestic and work environments.
The report “Every Breath We Take” sets out the way pollution from a wide variety of sources — including diesel fumes, wood burning stoves, pollen, and even candles and air fresheners — creates a cumulative impact on the UK population’s health and gives rise to huge costs, yet is poorly regulated, monitored, and understood, particularly when it comes to IAQ.
The report will be seized upon by the air conditioning and ventilation sector, which has already raised concerns about the lack of IAQ regulation, as an opportunity to improve standards and to emphasize the benefits of modern filtration technology in HVAC systems.
The report opens with a bleak summary of the cumulative impact of pollution: “Each year in the UK, around 40,000 deaths are attributable to exposure to outdoor air pollution, with more linked also to exposure to indoor pollutants. Air pollution plays a role in many of the major health challenges of our day, and has been linked to cancer, asthma, stroke and heart disease, diabetes, obesity, and changes linked to dementia. Neither the concentration limits set by government, nor the World Health Organization’s air quality guidelines, define levels of exposure that are entirely safe for the whole population. When our patients are exposed to such a clear and avoidable cause of death, illness, and disability, it is our duty as doctors to speak out.”
On top of the direct health risks, the doctors point out that the costs of unmitigated pollution are also extremely high. The report says: “The health problems resulting from exposure to air pollution also have a high cost to society and business, our health services, and people who suffer from illness and premature death. In the UK, these costs add up to more than £20 billion every year. Vulnerable people are prisoners of air pollution, having to stay indoors and limit their activity when pollution levels are high. This is not only unjust; it carries a cost to these individuals and the community from missed work and school, from more health problems due to lack of exercise, and from social isolation. Taking action will reduce pain, suffering, and demands on the NHS, while getting people back to work, learning, and an active life. The value of these benefits far exceeds the cost of reducing emissions.”
While naturally a significant part of the report is concerned with the risks of outdoor pollution, among the report’s 14 recommendations for change are several that relate directly to IAQ improvements. These include:
• Quantify the relationship between indoor air pollution and health. We must strengthen our understanding of the relationship between indoor air pollution and health, including the key risk factors and effects of poor air quality in our homes, schools, and workplaces. A coordinated effort among policymaking bodies will be required to develop and apply any necessary policy changes.
• Determine how global trends are affecting air quality. From increased energy production and consumption to global economic development and urbanization, we need to improve our understanding of how major social and economic trends are affecting air quality and its twin threat, climate change.
• Develop new technologies to improve air pollution monitoring. We need better, more accurate, and wider-ranging monitoring programs so that we can track population-level exposure to air pollution. We also need to develop adaptable monitoring techniques to measure emerging new pollutants, and known pollutants that occur below current concentration limits. We must develop practical technology — such as wearable ‘smart’ monitors — that empower individuals to check their exposure and take action to protect their health.
The report stresses that actions to decarbonize energy and heating sources and to improve kitchen extraction will have an overall beneficial effect, but notes that the increasing emphasis on insulation is reducing the benefits of ventilation.
But perhaps the most important recommendation from the doctors’ groups is that more work must be done on setting controls and guidelines at both a local and national level and strengthening existing instruments such as the Building Regulations to reduce indoor and outdoor pollution.
