  • Air quality Monitors Track Pollution Hot-Spots

    Situated in the south west of Wales, in a largely rural area bordering the Brecon Beacons, Carmarthenshire’s air quality is predominantly good. However, there are areas of concern where major roads pass through some of the County’s larger towns, including Llanelli, Carmarthen and Llandeilo, where air quality is dominated by the effects of road traffic. The County Council is therefore ...

  • Air pollution modelling, sensitivity analysis and parallel implementation

    A new approach for Sensitivity Analysis (SA) in the field of air pollution modelling is proposed and applied to the Unified Danish Eulerian Model (UNI-DEM), a large-scale air pollution model. The SA requires numerous model experiments with different values of the studied parameters. By simultaneous variation of these parameters we produce a set of multidimensional discrete functions. These huge ...

  • Integrated maximum efficiency air pollution control system

    A major uranium refiner required an air pollution control system to control emissions from their hazardous incinerator. The presence of radioactive material demanded that outlet emissions approach non-detectable levels. Macrotek was contracted to design and supply the system. Advanced, cutting edge technology was used to design a system with the lowest possible emissions, which has been ...

  • Air quality interventions and spatial dynamics of air pollution in Delhi and its surroundings

    The paper examines the spatial distribution of air pollution in response to recent air quality regulations in Delhi, India. Air pollution was monitored at 113 sites spread across Delhi and its surrounding areas from July?December 2003. From the analysis of these data three important findings emerge. First, air pollution levels in Delhi and its surroundings were significantly higher than that ...

  • California Air Resources Board (CARB) places higher restrictions on air pollution

    As part of the California Global Warming Solutions Act (AB 32) the Air Resources Board (ARB) has approved an early action measure to reduce high-global warming potential (GWP) greenhouse gas (GHGs) emissions by establishing new legislation and defining requirements related to improved monitoring of AC/HVAC systems, enforcement of regulations, reporting of refrigerant usage, and recovery, ...

  • Dispersion models and air quality data for population exposure assessment to air pollution

    Evaluating the extent of exposure to chemicals in absence of continuous measurements of their concentration in air and direct measures of personal exposure is crucial for epidemiological studies. Dispersion models can be a useful tool for reproducing spatio-temporal distribution of contaminants emitted by a specific source. However, they cannot easily be applied to short-term epidemiological ...

  • Selections from the history of environmental pollution, with special attention to air pollution. Part 1.

    Several comprehensive publications have been issued recently on the environmental pollution of past times (e.g. Tylecote, 1976; Nriagu, 1983a; Brimblecombe, 1987a; Goldstein, 1988; Healy, 1988; Brimblecombe and Pfister, 1990; Hughes, 1993; Markham, 1994; Brimblecombe, 1995; Karatzas, 2000, 2001; McNeill, 2001; Meszaros, 2001). The aim of this study is to give an overview of information on the ...

  • Metrics Matter: Conflicting Air Quality Rankings from Different Indices of Air Pollution

    Comparisons of air quality policies involve numerous considerations such as cost, health, effects on vegetation and materials, and aesthetics. Such assessments require difficult scientific and value judgments. These difficulties can also characterize comparisons that consider only physical and chemical air quality indices. We compare ambient tropospheric ozone concentrations from a baseline ...

  • Air pollution forecast in Portugal: a demand from the new air quality framework directive

    This work aims at developing and validating a numerical air quality operational forecasting system that will be applied over Portugal. The CHIMERE model was chosen for the chemistry-transport simulation using the meteorological parameters supplied by the MM5 mesoscale meteorological model, forced by the AVN/NCEP global forecasts. An experiment of 48-hour real-time forecast simulations was ...

  • Biotreatment of polluted air from a sludge treatment building in a BTF

    The problem Additionally to the basic level of pollution with malodorous pollutants, polluted air from a building with sludge presses showed temporarly extreme VOC-peak-loadings up to 1800 to 2000 mg/m³. Solution of the problem By a subsequent treatment in a two-step bio-trickling filter supported by LEVAPOR carrier for immobilisation of microorganisms, over 90% ...

  • EMEP/EEA air pollutant emission inventory guidebook — 2009

    The EMEP/EEA Air Pollutant Emission Inventory Guidebook (formerly referred to as the EMEP CORINAIR Guidebook) provides guidance on estimating emissions from both anthropogenic and natural emission sources. It is designed to facilitate reporting of emission inventories by countries to the UNECE LRTAP Convention and the EU NEC Directive. The Guidebook is prepared by the UNECE/EMEP Task Force on ...

  • Meteorology applied to urban air pollution problems: COST 715

    The requirements of the framework Directive on air quality assessment and management introduce real practical problems for the meteorological community. Some of the meteorological variables needed in urban air pollution assessments are not routinely measured and in normal circumstances the number of meteorological stations in urban areas is limited to a few sites, often just at airports. The ...

  • Interaction between air pollution and meteorological parameters in Erzurum, Turkey

    In recent years, the rapid increase in population density has caused increases in the consumption of fuel, and the outdoor air quality has deteriorated in the crowded urban areas of Turkey. Erzurum, a city in the eastern part of Turkey, is influenced by air pollutants such as SO2 and suspended particles. It is known that, in general, the air pollution concentrations have a close ...

  • Economic impacts of urban air pollution: valuation for Mumbai, India

    Urban air pollution is on the rise in many cities of the world. There are associated health impacts that affect urban residents, especially the poor. By doing economic valuation, it is possible to draw the attention of citizens, policy-makers and, of course, researchers to the extent of damage and the value of it. In this paper, such a valuation is done using time-series data for the suburb of ...

  • Air pollution from electricity-generating large combustion plants

    The study was initiated in the context of the review of the Integrated Pollution Prevention and Control (IPPC) Directive. This report presents the results of a study that assesses the theoretical potential to reduce air emissions of SO2 and NOX that might have occurred had the best available techniques (BAT) and associated emission levels (AELs), as described in the large combustion plant ...

  • Air Pollution Control Using Catalytic, Regenerative or Recuperative Systems

    For companies in a variety of industries, the clock is ticking regarding their compliance with local, state and federal clean air requirements. The need to provide adequate emission controls still looms on the horizon as these companies explore the various equipment and technology options available to them. While the guidelines regarding air pollution control are consistent by industry, a ...
