  • Better air quality for the people of Cyprus

    The Minister of Labour and Social Insurance of the Republic of Cyprus, Antonis Vasiliou, today opened a comprehensive system for air quality management in Cyprus. The system, developed by the Norwegian Institute for Air Research (NILU), gives the Cyprian authorities an advanced tool for the monitoring, assessment and management of air pollution in ...

  • Status of black carbon monitoring in ambient air in Europe

    Black carbon (BC) is increasingly discussed in science and environmental policy areas as an example of an air pollutant that affects both human health and contributes to climate change (e.g. WHO, 2012; UNEP/WMO, 2011; Bond et al., 2013; IPCC, 2013). In order to be able to make comparable measurements of BC in ambient air and to relate BC monitoring to health impacts and climate change it is ...

  • Air quality in Europe - 2014 report

    Despite considerable improvements in the past decades, Europe is still far from achieving levels of air quality that do not pose unacceptable risks to humans and the environment. Air pollution is the top environmental risk factor of premature death in Europe; it increases the incidence of a wide range of diseases and has several environmental impacts, damaging vegetation and ecosystems. This ...

  • A neural network implemented microcontroller system for quantitative classification of hazardous organic gases in the ambient air

    In this study, a microcontroller-based gas mixture classification system is proposed to use real-time analyses of the trichloroethylene and acetone binary mixture. A Feed Forward Neural Network (FFNN) structure is performed for quantitative identification of individual gas concentrations (trichloroethylene and acetone) in their gas mixtures. The phthalocyaninecoated Quartz Crystal Microbalance ...

  • Air quality in Europe — 2013 report

    Air quality continues to be a very important issue for public health, the economy and the environment. Europe has significantly cut emissions of several air pollutants in recent decades, greatly reducing emissions and exposure to substances such as sulphur dioxide (SO2), carbon monoxide (CO), benzene (C6H6) and lead (Pb). Despite improvements over several decades, air pollution continues to ...

  • Case study - Ambient air monitoring by PID detection - airTOXIC

    First Case THE PROBLEM: How to monitor air quality from 1 spot in 12 different towns ? THE SOLUTION The airToxic PID with the communication protocol MODBUS allows to transfer the results of the 12 instruments to a central room RESULTS airToxic PID allows to have an improved ...

  • 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 ...

  • An ambient indoor air environment is vital to ensure a safe and healthy workplace

    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”. Poor IAQ is a contributing factor to both short and long-term health issues, these ...

  • Methodology for developing an air quality index (AQI) for Tunisia

    Air quality index (AQI) is a quantitative tool through which air pollution data can be reported, providing information on how clean or polluted the air is. Several countries employ some type of air quality index to communicate the quality of their air. Some of these systems rely on relating measured (monitored) or predicted concentrations of air pollutants (results of modelling system). In this ...

  • Confronting allegations of air quality non-compliance

    A facility with an air quality permit must comply with all the conditions of that permit and demonstrate its compliance on an on-going basis. Unfortunately, no matter how diligently the facility and corporate staff strives to assure continuous compliance, unexpected compliance challenges can occur. For example, new equipment fails the emissions guarantees provided by equipment vendors; new staff ...

  • Air quality assessment in the EU: room for improvement?

    Different modelling approaches are used to design and assess air quality plans across Europe. This study assessed the strengths and weaknesses of these different approaches. The researchers conclude that a large variety of models is in use, without a preferred or standard model having emerged yet. They identify integrating local-scale and large-scale models and verifying models with measurements ...

  • Air quality planning for Durban, South Africa

    NILU has designed a programme to improve and update the monitoring and to assess the air quality for South Durban Basin. A planning tool for improving the air quality is currently under ...

  • Case Study: Odor Abatement Solutions

    Odor issues related to industrial processes are not uncommon.  An odor is caused by one or more volatilized organic compounds (VOCs) that humans can perceive by the sense of smell.  The challenge is that “odor is subjective, and what is sweet to some, can be a nuisance to others.   In most cases the ...

  • Every breath you take — air quality in Europe

    The characters in this story are fictional. However the data are real. The story is set on 27 July 2008 when an air quality warning was issued in Brussels. Anna is 37 years old and lives in the centre of Brussels. She and her young son Johan are planning a trip outside the busy city. Anna suffers from asthma and her doctor has warned of the dangers of air pollution, especially on hot summer days. ...

  • 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 ...

  • 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 ...

  • Indoor air quality can be improved by employing plants as walls

    The practice of planting ivy to climb up the walls of buildings has existed for centuries. Now, the trend towards sustainability and green building practices can lead to the development and use of living walls as a means of filtering and improving a building’s indoor air quality. Green walls are a living, breathing, regenerating type of cladding that can be as simple as a living art installation ...
