Numerous epidemiological studies have documented that current day levels of particulate matter air pollution (PM) are associated with adverse health effects including respiratory symptoms, lung function, hospital admissions for cardio-respiratory disease and mortality. Epidemiological studies of acute effects of air pollution have typically used the outdoor concentration measured at one or a few fixed sites to characterize daily exposure to PM. However, as people spend most of their time in various indoor environments, the indoor air quality is essential in determining the potential health effects.
The urban and indoor aerosols and health effects group aims to study and understand the air quality in various environments. The work combines field studies together with various type of modeling activities. The main focus is in real-time and long-term measurements with special attention to ultrafine and nanometer sized particles.
The main research topics and their role in the research unit are summarised in the following picture.
