SP Indoor Air Chemistry GroupOn average, people in Western Europe or the US spend around 90% of the time indoors. It means that exposure of people living in the industrialized countries to air pollutants occurs mostly indoors and that the indoor environment becomes extremely important for their well being.
The importance of atmospheric chemistry on ambient air quality was recognized over 50 years ago. The importance of atmospheric reaction processes in the indoor air has been previously neglected but quite recently obtained recognition. The chemistry occurring indoors is fundamentally the same as occurring outdoors. The organic compounds indoors are present at higher concentrations compared with outdoors. The time available for chemistry indoors, as well as concentrations of substances originating outdoors, is determined by the ventilation rates of the building.
The focus is on the reactions that are fast enough to be of importance for the indoor environments such as reactions of terpenes with ozone.
Indoor Air Chemistry Group is a part of the chemical section of the Department of Chemistry and Materials Technology at SP Technical Research Institute of Sweden (SP Sveriges Tekniska Forskningsinstitut). The group is working with chemical aspects of indoor air, emissions of volatile organic compounds from building materials, emissions of formaldehyde from wood-based building products and reactions of the indoor air organic compounds with ozone, including determination of the reactions products both as particles and gaseous compounds.
