‘Indoor Air Pollution and Health’ is a new in-depth study of air pollution in homes and shows that the concentration of particulate pollution in the homes of smokers who smoke indoors is six times higher than the World Health Organisation’s recommendation for general outdoor air quality.
This research examined the health impacts of air pollution in homes. It presents new information on levels of indoor air pollutants in homes using solid fuels for heating or cooking and in homes that have a resident smoker. The report highlights the need for public health policy and research professionals to develop interventions to address this.
The research was completed by NUI Galway and researchers at the University of Aberdeen, the Institute of Occupational Medicine, Edinburgh and the University of Birmingham.
Dr Marie Coggins, NUI, Galway explains: “Our research shows that air quality in homes using the solid fuels coal, wood, peat and gas is mostly comparable to that of outdoor air, however smoking at home creates much greater levels of air pollutants. Levels of particulate pollution were up to 17 times levels found outdoors. The impact of exposure to such levels, on vulnerable groups such as children, in homes where smoking occurs indoors needs urgent action.”
The average European spends 90% of their time indoors so the quality of the air people breathe plays a significant role in their health and well-being. Over the last few decades there have been many advances in the design and construction of domestic dwellings. As a result, the amount of air entering and leaving a typical building is estimated to be 10 times lower now compared to 30 years ago.
Dara Lynott, EPA Deputy Director General said: “The environment and health are intrinsically linked and this innovative research project on indoor air pollution aims to help protect both. This research, funded under the EPA’s STRIVE Research Programme, has identified air pollutants in homes as one of the key factors related to the exacerbation of respiratory illnesses. It will help public health policy and research professionals to develop interventions.”
The report authors have called for improved national survey campaigns to determine what proportion of the population is exposed to environmental tobacco smoke at home. Key recommendations include the following:
– A co-ordinated national campaign to educate smokers and non-smokers about the health effects from smoking at home and the promotion of smoke-free homes.
– More education as to the health effects of second hand smoke in the home as a means of reducing exposures.
– Greater focus on finding ways to encourage smokers to move towards smoke- free homes.
Welcoming the report Professor Luke Clancy, Director General, TobaccoFree Research Institute Ireland said: “It is very reassuring to find that Indoor Pollution in Ireland is very low even where coal, peat or gas is used but the findings about Secondhand Smoke are very worrying. The finding that particle load is almost 10 times the allowable level for healthy breathing in homes where smoking occurs is disappointing, especially since we know of some 4000 harmful chemicals that exist in tobacco smoke and we also know that over 40% of Irish children are exposed to Secondhand Smoke in Ireland. Action is needed to encourage people not to smoke or at least not to subject others to the health risks associated with inhaling other people’s smoke.”
