On Friday 10 December at 15:15, Karin Rosenkilde Laursen defends her PhD dissertation entitled "Acute health effects of fine and ultrafine particles in indoor air - Human exposure studies among vulnerable population subgroups".
As we spend up to 90% of our time indoors, our health and well-being are affected by our indoor climate. Growing evidence suggest that particle pollution is associated with a variety of adverse health effects ranging from inflammation to cardiopulmonary disease including cancer. Cooking, burning candles and electronic cigarettes (e-cigarettes) emit high amounts of fine and ultrafine particles. Ultrafine particles are so small in size, that they can penetrate into the deepest regions of the lungs, potentially translocate into the blood stream, from where they can access vital organs such as the heart and brain. At present millions of people are using e-cigarettes worldwide and exposure to the aerosol has become a serious public health concern. Furthermore, people with respiratory disease are known to be more susceptible to particulate air pollution than the background population due to chronic inflammation in the respiratory tract.
The aim of the present PhD study was to examine acute health effects from short-term exposure to cooking, candles and aerosol from e-cigarettes, respectively, among people with respiratory disease. In two different randomized controlled double-blinded exposure studies individuals with i) COPD were exposed to aerosol from e-cigarettes and ii) young individuals with mild asthma were exposed to cooking and burning candles on separate occasions. Their health were examined before, during and after the exposures.
The summary is written by the PhD student.
The defence is public and takes place in Samfundsmedicinsk Auditorium (Building 1262), Aarhus University, Bartholins Allé 4, 8000 Aarhus C and online. Please read the attached press release for more information.
