SLB is a department at the Environment and Health Administration (EHA) of the city of Stockholm. SLB supports several local municipal authorities with air quality control and assessments, offers commercial services (air quality measurements, modelling, consultations), and is also involved in several scientific research projects. SLB has been the operator responsible for the Eastern Sweden Air Quality Association since it started in the beginning of the 1990s. This association has grown since then and now covers an area with more than 3 million inhabitants and consists of 60 member organisations of which 50 are municipalities and 4 regional county administrations, 3 energy production companies, 2 national administrations, and two university departments (Department of Environmental Science and Analytical Chemistry at Stockholm University and The Institute of Environmental Medicine at the Karolinska Institute). SLB cooperates with several national and international research organisations.

SLB has expertise in meteorology, air quality monitoring and emission measurements, emission and dispersion modelling, GIS, exposure assessment and health effects of air pollutants. The monitoring includes both regulated and unregulated gaseous and particulate air pollutants as well as meteorological and traffic data. All data is automatically transferred to a central database every hour and some data is publically available in real time at SLB provides prognoses of air quality for radio and newspapers. A detailed emission database is updated annually in cooperation with local municipalities and regional administrations. Emission data representing current and future planning scenarios is used in dispersion model calculations for mapping of air pollutants, consequence analyses of e g future traffic planning scenarios, and health impact assessments. Model calculations are validated using the monitoring data. Wind comfort modelling can also be provided using computational fluid dynamics models. SLB is responsible for and participates in several research projects focussing on, for example, assessment of abatement measures to reduce impacts of air pollution emissions, air pollution epidemiology, and health effect impact assessments.
