Evolving the ensemble of predictors model for forecasting the daily average PM10
The paper develops the methods of accurately forecasting the daily average concentration of PM10. We apply the Support Vector Machine in the regression mode (SVR) as the main workhorse of prediction. Different approaches to the prediction are tried: the direct application of SVR, the combination of SVR and wavelet decomposition, and the Blind Source Separation (BSS) method for improving the final ...

Fireworks air pollution in Slovenia
Over the 'Christmas–New Year' period 12/2010–01/2011, PM10 air pollution measurements on most of the automatic measuring stations in Slovenia reached extreme values of up to 300 µg/m³. Analysis shows a very close correlation with the timings of the fireworks displays in the areas. This paper shows the other side of this cultural enjoyment - the effect on PM10 air pollution. As the correlation ...

Ambient air quality of Kathmandu valley as reflected by atmospheric particulate matter concentrations (PM10)
This paper presents the analysis and interpretation of ambient particulate matter concentrations measured as PM10 at a network of six air monitoring stations in Kathmandu valley during the years, 2003 through 2005. The purpose was to understand the pollution trends associated with different areas considering levels particulate matter concentrations representing the ambient air quality of ...

Modelling emission trends from non-constant time series of PM10 concentrations in Christchurch, New Zealand
This paper presents an attempt to model the trend of emissions through analysis of a time series of PPM10 concentrations in Christchurch, New Zealand. Emissions are not constant over time, but show high seasonality. Fluctuations are removed by creating a time series in which concentrations do not show dependency on ambient air temperature. Remaining meteorological influences are removed through ...

The role of atmospheric circulation in air pollution distribution in Katowice Region (Southern Poland)
The Katowice Region is the most urbanised and industrialised region in Poland. Local meteorological and circulation conditions significantly influence the pollution level. The study has integrated measurement results of temperature and selected air pollution indices (PM10, SO2, NO, NO2, O3, CO) with the calendar of synoptic circulation types by Niedzwiedz. Because the highest values of ...

Reverse modelling for the determination of fugitive sources of PM10
Time-series of half-hourly PM10 concentrations and meteorological data measured near industrial sites where dusty materials are processed can be used to estimate PM10 source strengths for these activities using reverse modelling. Reverse modelling starts with building an over-determined system of linear equations: Observed_Cmj = Computed_Cmj(known sources)+ Σ i=1, NComputed_Cmj(Qi) where the ...

Mortality rates and air pollution levels under different weather conditions: an example from Western Europe
According to results of the World Health Organization (WHO) high PM10 concentrations caused a reduction of the average life expectancy of 10.2 months in Germany. The objectives of this study are to determine the influence of the synoptic scale flow patterns on air pollutants and to quantify effects of air pollution on mortality rates. To describe the synoptic situation two weather type ...

Evaluation of air pollution trends in Istanbul
Previously, SO2 and PM10 (particulate matter less than 10 Bm in size) concentration distributions have been investigated in order to assess air pollution in Istanbul during the winter season (November–March) in which the concentration of these pollutants had reached formidably high levels due to the consumption of low-quality fuels (mainly coal) for residential heating. In this study, the effect ...

The study of temple and pastureland particle-bound polycyclic aromatic hydrocarbons concentrations in central Taiwan
The concentrations of polycyclic aromatic hydrocarbons in the atmosphere were measured simultaneously at Tzu Yun Yen temple and Tung Hai University pastureland in Taichung, central Taiwan. At both sites, 24 h samplings were performed between August 2001 and December 2001. The results indicated that high molecular mass polycyclic aromatic hydrocarbons are predominant at the Tzu Yun Yen temple ...

Atmospheric concentration and fluxes of trace elements in Visakhapatnam City of India
Airborne PM10 samples were collected during winter and summer at three different sites in a coastal city, Visakhapatnam, India. Average individual trace element concentrations fluctuated between 19 ng m−3 (Cd) and 4,802 ng m−3 (Zn). Average trace element concentrations for winter were observed higher than those of summer. Dry deposition flux was estimated using metal concentration in ambient air ...

Numerical study of some high PM10 level episodes
The study examines the ability of US EPA Models-3 system to reproduce air pollution episodes and to evaluate the role of different processes in the PM10 pattern formation. The case study focuses on three major PM10 episodes, that occurred over Germany in February and March of 2003. The emission input is prepared on the basis of the TNO inventory. The simulated PM10 concentrations are compared ...

Criteria for the assessment of air quality levels in homogeneous areas
A methodology is proposed for the appraisal of the data to confront with air quality limits. The methodology assesses air quality levels on the basis of mean values calculated as an average of all data collected in homogeneous areas, from monitoring stations located in sites not conditioned from local sources emissions. The resulting value represents the air quality of the area better than a ...

Plans and programmes to improve air quality over Portugal: a numerical modelling approach
PM10 limit values have been surpassed in the northern region of Portugal, and, according to European legislation, Plans and Programmes (PP) must be designed and implemented to reduce those PM10 levels. The Air Pollution Model (TAPM) was applied over the study region, to the year 2004, for the reference situation with the current PM10 emissions; and, for the reduction scenario with PM10 emissions ...

Modelling the impact of sea-salt particles on the exceedances of daily PM10 air quality standards in the Netherlands
Particles generated at the sea surface contribute to PM10 levels in coastal areas. Current estimates suggest annual average contributions of up to 10 µg/m³ along the North Sea coast in the Netherlands. In this paper the generation of size-segregated sea salt particles is described as a function of meteorological parameters. These particles are fed into a model where transport and deposition ...

Personal exposure to particulate air pollution in transport microenvironments
Personal measurements of exposure to particulate air pollution (PM10, PM2.5, PM1) were simultaneously madeduring walking and in-car journeys on two suburban routes in Northampton, UK, during the winter of 1999/2000.Comparisons were made between concentrations found in each transport mode by particle fraction, between differentparticle fractions by transport mode, and between transport ...

Construction sites pollution monitoring - Case study
Constructing buildings, roads and other infra structure can have a substantial, temporary impact on local air quality. Airborne contaminants generated are spreading around in the surrounding neighborhood during activities (excavation, raw material extraction, demolition, transportation, painting, covering, concrete…), mostly carried by wind. The main construction contaminants include PM10 ...

Air pollution and the influence of sources on Paulinia (Brazil) and surroundings
The air quality in the industrial area and surroundings of the city of Paulinia (state of Sao Paulo, Brazil) has been investigated by analysing the concentration of air pollutants (SO2, PM10, NO, NO2, CO and ozone) and identifying the main sources of air pollution. A mobile pollutant monitoring unit was used to collect the data at five different sites from November 2000 to July 2002. Critical ...
