Medics link deaths to poor indoor air quality

Indoor air pollution, including that caused by emissions from faulty boilers, gas cookers and heaters, cause or contribute to at least 40,000 UK deaths each year, according to a new report from two major UK health bodies. The research from the Royal College of Physicians and the Royal College of Paediatrics and Child Health makes direct reference to the impact of indoor air quality (IAQ) on human health and premature death rates.

While both colleges said more specific research was needed into the key risk factors, the reports said it was clear that increased levels of airtightness were adding to a growing problem.

The reports point to emissions from faulty boilers, gas cookers and heaters, as well as irritant chemicals from new furniture, air fresheners and household cleaning products, as contributing to rising health problems inside well-sealed buildings. House-dust mites, mould and dander from pets can also damage health, particularly in unborn and young children, the report said.

"The developing heart, lung, brain, hormone systems and immunity can all be harmed by pollution," the report said. "Research is beginning to point towards effects on growth, intelligence, asthma, and development of the brain and coordination. Harm to babies and children will have an impact that lasts far into the future."

Dr Andrew Goddard, at the Royal College of Physicians, said: "Taking action to tackle air pollution in the UK will reduce the pain and suffering for many people with long term chronic health conditions, not to mention lessening the long term demands on our NHS."

While the report highlights the need for a wide-ranging set of measures to tackle the problem of outdoor air pollution, including tougher regulations such as reliable testing of emissions from vehicles, it also calls for more and deeper research into indoor air pollution, stating: "We must strengthen our understanding of the key risk factors and effects of poor air quality in our homes, schools and workplaces. The drive to reduce energy costs, by creating homes with tighter air tightness but no more ventilation, could be making the situation worse."
