Non-exhaust traffic induced emissions are a major source of airborne particulate matter in most European countries. This is particularly important Nordic and Alpine countries where winter time road traction maintenance occurs, e.g. salting sanding, studded tyres used. Though the total mass generated by wear sources key factor non-exhaust emissions, these also strongly controlled surface moisture conditions. In this paper, Part 2, sub-model coupled dust model (NORTRIP) described. We present...
Abstract. Residential wood combustion (RWC) is an important contributor to air quality in numerous regions worldwide. This study the first extensive evaluation of influence RWC on ambient several Nordic cities. We have analysed emissions and concentrations PM2.5 cities within four countries: metropolitan areas Copenhagen, Oslo, Helsinki city Umeå. evaluated for relevant urban source categories modelled atmospheric dispersion regional scales. The emission inventories were based local surveys,...
Abstract. A mathematical model is presented for the determination of human exposure to ambient air pollution in an urban area; a refined version previously developed EXPAND (EXposure Particulate matter And Nitrogen oxiDes). The combines predicted concentrations, information on people's activities and location population evaluate spatial temporal variation average different microenvironments. revisions modelling system containing include improvements associated emission dispersion system,...
Abstract. Reliable and self-consistent data on air quality are needed for an extensive period of time conducting long-term, or even lifetime health impact assessments. We have modelled the urban-scale concentrations fine particulate matter (PM2.5) in Helsinki Metropolitan Area a 35 years, from 1980 to 2014. The regional background were evaluated based reanalyses atmospheric composition global European scales, using SILAM model. high-resolution urban computations included both emissions...
We estimated the CH4 budget in Finland for 2004–2014 using CTE-CH4 data assimilation system with an extended atmospheric observation network of seven sites from to surrounding regions (Hyytiälä, Kjølnes, Kumpula, Pallas, Puijo, Sodankylä, and Utö). The average annual total emission is 0.6 ± 0.5 Tg yr−1. Sensitivity experiments show that posterior biospheric estimates are between 0.3 0.9 yr−1, which lies LPX-Bern-DYPTOP (0.2 yr−1) LPJG-WHyMe (2.2 process-based model estimates. For...
Abstract. We have numerically evaluated how effective selected potential measures would be for reducing the impact of road dust on ambient air particulate matter (PM10). The included a reduction use studded tyres light-duty vehicles and salt or sand traction control. these street canyon located in central Helsinki four years (2007–2009 2014). Air quality measurements were conducted two years, 2009 2014. Two emission models, NORTRIP (NOn-exhaust Road TRaffic Induced Particle emissions) FORE...
Abstract. The predictions of two road dust suspension emission models were compared with the on-site mobile measurements factors. Such a quantitative comparison has not previously been reported in reviewed literature. used Nordic collaboration model NORTRIP (NOn-exhaust Road TRaffic Induced Particle emissions) and Swedish–Finnish FORE (Forecasting Of Emissions). These describe particulate matter generated by wear surface due to traction control methods processes that particles into air. An...
Air pollution has been suggested to be associated with depression. However, current evidence is conflicting, and no study considered different sources of ambient particulate matter an aerodynamic diameter below 2.5 µm (PM2.5). We evaluated the associations long-term exposure PM2.5 from road traffic residential wood combustion prevalence depression in Helsinki region, Finland.We conducted a cross-sectional analysis based on Capital Region Environmental Health Survey 2015-2016 (N=5895)....
This paper presents the first outcomes of "FAIRMODE pilot" activity, aiming at improving way in which air quality models are used frame European "Air Quality Directive". Member States may use modelling, combined with measurements, to "assess" current levels and estimate future under different scenarios. In case potential exceedances Directive limit values, it is also requested that they "plan" implement emission reductions measures avoid exceedances. both "assessment" "planning", can should...
Abstract. This article has investigated the contribution of residential wood combustion (RWC) to fine particulate matter (PM2.5) concentrations in Helsinki metropolitan area (HMA) for 6 years, from 2009 2014. We have used PM2.5 measured at eight air quality measurement stations. The dispersion emissions on an urban scale was evaluated with multiple-source Gaussian models, UDM-FMI (urban model Finnish Meteorological Institute) and CAR-FMI (Contaminants Air a Road Institute), regional using...

Air pollution causes significant excess mortality and health effects. Action plans required by the EU legislation should optimally account for complex interactions of population distributions, time-activity sources air pollution. This paper presents FUMAPEX study results on probabilistic exposure modelling evaluation distributions during selected episodes in Helsinki. The quality model characterised best local origin, while highest exposures occurred a long-range transported episode (average...
Urban areas form a mosaic of microenvironments and structures, such as street canyons that are susceptible to elevated levels traffic related pollutants. Street relevant topic in air quality research modelling since they prone reduced natural ventilation when exposed increased emissions, can pose serious risk public health. We applied magnetic biomonitoring using moss bags evaluate the Operational Pollution Model (OSPM) study vertical distribution modelled particulate matter (PM), PM heavy...
