  • Selecting the Right Air Quality Monitor

    There are many types of air quality monitors available, but which one is the best choice for measuring gaseous air pollutant concentrations? There are two classes of such air quality monitors: sampling monitors and in-situ monitors (“in-situ” = “in the original position”). Sampling monitors utilises a manifold through which the air to be analysed is pumped. A small air ...

  • The ‘ins and outs’ of air quality monitoring

    The National Institute for Health and Care Excellence (NICE) recently issued draft guidance on ‘Air pollution - outdoor air quality and health.’ In the following article Jim Mills, Managing Director of Air Monitors Ltd, explains why there will need to be more funding for monitoring if the mitigation measures mentioned in the guidance are to be implemented effectively. Jim also ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Chromatotec monitor air quality in Arcachon Bay through its own air quality station

    Chromatotec® made this summer the inauguration of its private monitoring station in Andernos-les-Bains. With a wealth of experience, thanks to which it already deployed massively its systems around the world, the group wanted to implement its own monitoring station to have complementary information to the actual air quality network. These data will allow the group to extend its ...

  • Continuous monitoring of multiple Indoor Air Quality (IAQ) parameters

    Measuring and monitoring hazardous gases is a critical issue in industrial and workplace safety.  Many facilities are especially vulnerable to the effects of an unhealthy indoor environment when fuel-burning vehicles are used indoors. Placing an IAQ monitoring system in buildings and facilities enables immediate identification of IAQ problems, the sources and causes of any problem can be ...

  • Vehicular Emission (Air Quality) Monitoring Study in Lagos, Nigeria

    INTRODUCTION On October 12, 2006 residents around Lagos Metropolis woke up, to their wonderment, to a hazy atmosphere which was very unusual to Lagosians and indeed to so many people. Many were lost as to what was happening. Some schools, especially around ...

  • Barrick Gold and Golder Associates Implement EQuIS for Automated Air Quality Data Monitoring System

    As part of a new Air Quality and Meteorology Network in the Dominican  Republic, Pueblo Viejo Dominicana Corporation (PVDC) have committed to implementing four automated air quality data monitoring systems. Three stations are already in place, with a fourth to be added pending site location approval. The stations are installed and maintained by Golder Solutions, the successful  vendor ...

  • Mapping Quality Assurance Requirements for Continuous Mercury Monitoring Systems

    The Clean Air Mercury Rule (CAMR) requires coal-fired electric power plants to install and operate mercury  continuous monitoring systems by December 31, 2008 such that they will have 12 months of “submittable” data by 1 January 2010. For all practical purposes, “submittable data” are “quality-assured data” that meet the extensive quality control requirements cited in the various regulations that ...

  • Monitoring Air Makes Sense

    Did you know that air filters were originally put in air handling systems to protect the life of the equipment, not human life? And that it is not uncommon for air filters to get changed less frequently to save on maintenance costs? Monitoring input from sensors can tell operators when filters and media need changing. We have required food labels that list all ingredients. Why not electronic ...

  • PRESAXIO regional air quality modelling system: validation and applications

    Different operational air quality forecasts (ESSEM Cost Action 0602) are currently available in Europe. However, most of them are not suitable for regional application and, also, their coarse outputs do not fit well with air quality management needs. In this work, PRESAXIO regional air quality modelling system is validated and applied over Galicia (NW of Spain), including WRF and CHIMERE models. ...

  • The benefits of monitoring compressed air

    Compressed air is used in many manufacturing processes for many different reasons, from the actuation and control of pneumatic valves and cylinders to the operation of process machinery and tooling. It can also be used as a transport medium for bulk materials or as a purge gas. For all its uses it is nonetheless expensive. This is why, through detailed monitoring, a business can enjoy the ...

  • Green Technology for Healthy Air and Energy Conservation: New Technology for Continuous, Indoor Air Quality Monitoring

    Continuous monitoring for indoor, Volatile Organic Compounds (VOCs) has been carried out by VOC Technologies (VOCTEC) during and after construction of Epler Hall, a newly-built green building on the PSU campus. Epler is a 6-story building devoted largely to student apartment residences, with classroom and office space on the first floor. Epler has no central heating/ventilation system. Epler’s ...

  • A GIS based air quality system for the Apulia region, southern Italy

    A GIS based air quality modelling system has been developed in Apulia region in the Southern Italy, to support local authorities in air quality management. Meteorological and dispersion simulations were performed for the year 2005. Predictions have been compared with concentration data from the air quality monitoring network. Results evidence a good correlation between predictions and ...

  • Air quality modelling as a supplementary assessment method in the framework of the European Air Quality Directive

    According to the European Air Quality (AQ) Directive, member states must annually report their AQ to the European Commission (EC). This report can be based on modelling data if the concentration levels do not exceed the established lower assessment thresholds (LAT), or on combined data from modelling and monitoring systems (supplementary assessment methods) if concentrations levels are below the ...

  • 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 ...
