  • Further insights into the composition, source and toxicity of pahs in size‐resolved PM in a megacity in China

    Concentrations of PM10 and PM2.5 and 16 polycyclic aromatic hydrocarbons (PAHs) were measured. The average concentrations of PM10 and PM2.5 reached 209.75 μg/m3 and 141.87 μg/m3; and those of ΣPAHs were 41.46 ng/m3 for PM10 and 36.77 ng/m3 for PM2.5. The mass ratio concentrations were 219.23 μg/g and 311.01 μg/g in PM10 and PM2.5, respectively. Three sources and their contributions for PAHs ...

  • Chemical and morphological study of PM
    10
    and PM
    2.5
    in Pune, India

    PM10 and PM2.5 ambient samples were collected by a particulate sampler (APM 550, Envirotech) in the Department of Chemistry, University of Pune, India. Exposed filters were used to determine the mass, ionic composition and morphology of fine PM. The mean PM10 and ...

  • 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 ...

  • Air–quality impact of PM10 emission in urban centres

    This paper calculates a detailed inventory of PM10 emissions in the urban area of Mendoza, Argentina, and evaluates the impact of such emissions by using the CALPUFF dispersion program. It includes direct and indirect emissions from mobile sources; emissions from industrial sources and fugitive emissions from unpaved road and dust production from bare land. The main results show the relevance of ...

  • 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 ...

  • Office Printers Emit Ultra fine particle pollution

    We’ve heard quite a bit about particulate matter PM10s and PM2.5s as components of air pollution that we are exposed to on a daily basis. Recent research papers are highlighting the dangers of ultra fine particles (UFPs), which have a diameter of less than 0.1 micrometres (or 100 nanometres). By contrast, the diameters of particulate pollution from PM10s and ...

  • 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 = ...

  • Elevated PM10 concentrations and high PM2.5/PM10 ratio in the Brussels Urban area during the 2006 car-free Sunday

    The results of the Car-Free Sundays in Brussels demonstrate the close relationship between the traffic and the presence of the gaseous pollutants such as NO, NO2, CO, CO2 and O3 in a traffic environment. The relationship with PM10 and PM2.5 seems to be much more complex. In fact, the PM10 and PM2.5 concentrations on the Car-Free Sunday 2006 were amongst the highest that year and they were three ...

  • Characteristics and expected health implications of annual PM10 concentrations in Athens, Greece

    Several characteristics of the annual PM10 concentrations in the Athens conurbation, together with the expected health implications, are investigated using data from the Athens network of monitoring stations. Annual PM10 concentrations show a decreasing trend; however, concentration levels are still high, exceeding the current EU air quality standard at four monitoring stations and the Air ...

  • EPA shifts PM2.5 PSD permitting policies

    On August 12, 2009, EPA created a significant stir in the regulated community when it issued an order that signals a significant shift in how the agency intends particulate matter with a diameter less than 2.5 micrometers (PM2.5) emissions to be regulated under the Prevention of Significant Deterioration (PSD) program. The order specifically applied to petitions filed by environmental groups ...

  • Variability of PM10 concentrations dependent on meteorological conditions

    The influence of atmospheric exchange conditions on near-surface PM10 concentrations is analysed for four cities in the South-West of Germany in the period from 2001 to 2005. For each city, the PM10 data originates from roadside stations and Urban Background (UB) stations, that is, two types of official urban air quality monitoring stations characterised by different emission situations. The ...

  • Statistical characteristics of ozone and PM10 levels in a medium-sized Mediterranean city

    A statistical analysis of ozone and PM10 concentration levels in the area of Volos, a medium-sized Greek coastal city, was carried out for the period 2001-2003. The data analysis revealed that the Daily Maximum Hourly (DMH) value of ozone concentration reaches a maximum of 160 µg/m³ during summer; it is observed during afternoon hours and is associated usually with winds from southern directions. ...

  • Inorganic and Carbonaceous Components in Indoor/Outdoor Particulate Matter in Two Residential Houses in Oslo, Norway

    A detailed analysis of indoor/outdoor physicochemical aerosol properties has been performed. Aerosol measurementswere taken at two dwellings, one in the city center and the other in the suburbs of the Oslo metropolitanarea, during summer/fall and winter/spring periods of 2002–2003. In this paper, emphasis is placed on thechemical characteristics (water-soluble ions and carbonaceous components) of ...

  • The Emission Rate, Biological Characterization, and Transport of Aerosols Emitted During the Disk Incorporation of Class B Biosolids

    Biosolids contain metal, biotoxin, and pathogen concentrations that are greater than the agricultural soils to which they are applied. Once applied, biosolids are incorporated into soils by disking and this process generates aerosols that may be a health hazard to workers and nearby residents. Field studies at a Central Arizona biosolids land application site were conducted to characterize the ...

  • Inter-Relationships and Seasonal Variations of Inorganic Components of Pm10 in a Western Pacific Coastal City

    Five year (1995–1999) datasets for inorganic major and trace components in PM10 from three monitoring sites in Hong Kong are presented. The concentrations of most chemical constituents show a high degree of seasonality, with high concentrations in winter but low ones in summer, resulting from the combined effects of summer monsoon scavenging and the influx of the continental air mass of the ...

  • PM10 and PM2.5 - legislation, measurement and control

    New standards for PM10 and PM2.5 in ambient air are being formulated in Europe and the USA. There is much controversy over this legislation, not only with respect to the stringent limits proposed, but also due to the many problems associated with ensuring compliance with standards for a pollutant which is so poorly understood. New sampling and analysis techniques ...

  • Roadside particulate levels at 30 locations in the Kathmandu Valley, Nepal

    Roadside particulate levels (PM10) at 30 locations throughout the Kathmandu Valley, Nepal are reported. There were seven sampling cycles from January to December 1999. PM10 levels ranged between 1000 and 6000 µ/m³ for 1-h sampling. There was no consistent trend in PM10 levels with respect to monitoring cycle, average precipitation or wind speed. There is no WHO ...
