  • A Critical Evaluation of the South African Air Quality Offsets Guideline

    There is wide recognition in South Africa to the link between the quality of life and quality of the air we breathe. The Department of Environmental Affairs (DEA) attempts to improve air quality through two key regulatory tools; emission limits, which regulate the maximum concentration of certain pollutants permissible within certain, ‘listed’ industrial stacks or vents, and ambient ...

  • Double benefit of monitoring Indoor Air Quality (IAQ)

    It is a difficult balance to save money and energy yet maintain a comfortable and healthy indoor air environment. A logical solution to controlling indoor air pollution is good ventilation coupled with IAQ monitoring using gas sensors. This can ensure healthy indoor air as well as a more efficient HVAC system.  Typical IAQ investigation and examination consists of taking single-point ...

  • Air quality monitoring: establishing criteria for station classification

    According to the Council Decision 97/101/EC on Exchange of Information, stations should be classified in relation to the type of area where they are located and according to the type of dominant emission sources influencing the air pollutant concentrations at the station. A detailed methodology was developed for the validation of the classification of Portuguese air quality monitoring stations, ...

  • Remote monitoring of Indoor Air Quality (IAQ)

    Indoor air quality (IAQ) relates to a number of environmental factors inside a building that can impinge on the health, comfort, or work performance of the building’s occupants. Monitoring IAQ is vital because it is estimated that the average person spends 90% of their time breathing “indoor air”. Remote monitoring of IAQ sampling data collected by PPM ...

  • Why monitor Indoor Air Quality (IAQ)?

    Indoor Air Quality (IAQ) relates to a number of environmental factors inside a building that can impinge on the health, comfort, or work performance of the building’s occupants. Monitoring IAQ is vital because it is estimated that the average person spends 90% of their time breathing “indoor air”. In order to accurately understand a building’s indoor air quality, it is ...

  • Cartography for air quality monitoring: the geostatistical approach

    Being able to provide quick and accurate pollutant maps from readings at isolated measurement stations is becoming more important today in light of the European norms on air quality and the public’s demand to be informed. Commonly used algorithms for cartography are quick but their accuracy remains to be determined.Firstly, the choice of method is arbitrary and based on user’s subjective ...

  • NILU developed the air quality monitoring programme for Egypt

    The Environmental Information and Monitoring Programme (EIMP) for Egypt was successfully implemented during a five-year period from 1996 to 2001. From mid-2001 and onwards the EIMP has been operated by the Egypt Environmental Affairs Agency ...

  • Rough set-based regionalisation in air quality monitoring

    Regionalisation is to organise a large set of spatial objects into spatially contiguous regions despite optimising the homogeneity of the derived regions, while representing social and economic geography. To confront this problem, it is necessary to classify the regions to form groups that are homogeneous in air quality attributes. It is to develop a system that applies data mining techniques to ...

  • 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 ...

  • The challenges and benefits of local air quality monitoring

    A new generation of air quality monitors is now being offered to provide localised, real-time air quality readings – but the potential benefit is only just starting to be realised. It is generally accepted that whilst measurements from air quality reference stations are highly accurate, they are not sufficiently location-specific. Key pollutants – such as NO2 and PM2.5 ...

  • Air quality monitoring and assessment programme for Botswana

    An Air Pollution Monitoring and Surveillance Program (BAQMAP) is being developed, installed and tested for Botswana. The project is funded partly by NORAD and partly by the Botswana Government.  The project is undertaken in a co-operation between Norwegian Institute for Air Research (NILU) in Norway and Department of Mines (DoM) in Botswana. NILU shall provide professional assistance in the ...

  • Simultaneous determination of PM fractions, particle number and particle size distribution in high time resolution applying one and the same optical measurement technique

    Abstract The Fidas fine dust monitoring systems comprise an optical aerosol spectrometer, which is characterized by very good instrument characteristics, and utilize a sophisticated approach to convert the measured information on particle number and particle size into mass concentrations. As monitoring of PM requires reliable and quality-controlled performance of the measuring systems, ...
