We have studied particulate matter (PM) concentrations,PM10 and PM2.5, measured in an urban air qualitymonitoring network in the Helsinki Metropolitan Area during1997–1999. The data includes PM10 concentrationsmeasured at five locations (two urban

Air Pollution Modeling and Its Application XIX ISBN: 9781402084522
A mathematical model EXPAND (EXposure model for Particulate matter And Nitrogen oxiDes) can be used to evaluate human exposure to air pollution in an urban area. The model combines the predicted concentrations and the information on the time use of t

The enhancement of recoilless fraction (f factor) in restricted geometries is studied. The experiments were carried out using the119Sn resonance in SnCl4 molecules trapped in porous glass. A theoretical approach to explain the increase of thef factor

Urban Air Quality: Monitoring and Modelling ISBN: 9789401061551
The Helsinki Metropolitan Area Council (YTV) is responsible for air quality monitoring in the Helsinki area. Air quality has been monitored periodically since the late 1950s. An automatic SO2 monitoring network was constructed in 1975 and TSP measure
