  • NILU monitoring air quality for Statoil

    A programme to monitor the environment around the Snøhvit-development in Finnmark county in Northern Norway has been established by Statoil. Norwegian Institute for Air Research (NILU) will be monitoring air quality and precipitation quality before and after the large ...

  • How Does a Gas Analyser Work?

    Whatever you want to detect, you need to identify a property of the object that is easy-enough to measure. When it comes to monitoring and analysis of gaseous species (atoms or more commonly molecules), it turns out that it often is possible to utilize the optical properties of the gas. You need a light source, a light detector, and a characteristic behaviour of the gaseous species in question ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Monitoring Environmental Quality

    ' In order to determine the effectiveness of actions to improve environmental quality it is necessary to be able to measure relevant environmental parameters at a level of detail which is accurate enough to distinguish the anticipated changes. However, the establishment and maintenance of monitoring systems is time-consuming and expensive and therefore the scale of such systems needs to be kept ...
