  • 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 ...

  • Oxygen Monitors now Required for Nitrogen, Argon, Helium, and CO2 use in Denver

    The Colorado city of Denver recently passed a new law that requires facilities that use insert gas to install oxygen deficiency monitors wherever these gases are used in excess of 100 pounds. Learn what the new law requires from businesses and how an oxygen sensor protects your employees, your business, and your peace of mind.  What Denver's New Law Requires  The law ...

  • Ambient Air Quality Analysis of Toxic Gases and Priority

    The EPA regional offices who continuously monitor ambient air quality have determined that combustion by-products and automobile exhaust make up the largest source of air pollution throughout the U.S., with more severe conditions existing overseas. Despite concerns about the conditions outdoors, air quality in the workplace and home environment receive even more attention. The EPA’s list of ...

  • Why the use of a CO2 monitor may not be the best solution for protecting workers against leaks from beverage dispensing systems in the fast food industry

    Carbon Dioxide (CO2) is the primary compressed gas used for dispensing beverages at fast food chains. This gas is also used in restaurants, gas stations, and grocery stores. When CO2 leaks into a confined space or basement, it creates a very unsafe environment for employees because it lowers the concentration of breathable oxygen.  History seems to repeat itself all too often while ...

  • Using Open Path TDLAS CO2 Sensors for Carbon Capture and Storage Projects

    Public confidence in CCS projects worldwide is not very high. Many believe that CCS is not permanent storage, and at great expense to govermnents who are funding these projects. Effective monitoring and verification programs could go a long way to improve public perception.  Our Spectra-1 open path TDLAS gas sensor has shown very high accuracy in monitoring ambient CO2 levels. Better than ...

  • Comparison of indoor air quality in restaurant kitchens in Tehran with ambient air quality

    Air pollution is a major environmental health problem, affecting developed and developing countries around the world. Although the indoor air database is weak due to the scarcity of monitoring results, these estimates indicate that a serious indoor air problem may exist in developing countries. In developed countries, pollutant concentrations indoors are similar to those outdoors, with the ratio ...

  • 2013: a ‘perfect storm’ in air quality

    As many countries fail to meet air quality targets and large numbers of premature deaths still result from air pollution, Jim Mills, a particulate monitoring specialist and Managing Director of Air Monitors, explains why 2013 will be a pivotal year. In November 2011 Janez Potočnik, European Commissioner for the Environment, expressed his determination to make 2013 the ‘Year of ...

  • Black Carbon – the elephant in the room!

    Traditionally, ambient particulates have been measured gravimetrically according to their size. However, in this article Jim Mills, Managing Director of Air Monitors, will demonstrate that the time has come to change or at least augment the way ambient particulates are monitored and regulated. Air Monitors has supplied most of the UK's ambient monitoring network, but Jim will explain why the ...

  • The shifting sands of GHG regulation

    So far this year, there have been significant developments on U.S. climate change policy, including movement toward mandatory reporting and regulation of greenhouse gas (GHG) emissions at the federal level via either a cap-and-trade program or possibly existing Clean Air Act mechanisms. While the specifics are still uncertain regarding how these regulatory developments and legislative actions ...

  • Safety Systems Depend on Reliable Field Sensors (Emphasis on Fire and Gas Detectors)

    Abstract Because not all hazards are the same, identifying and quantifying the hazard is the starting point in choosing sensing technology. Not all detectors are the same, and they should be selected according to their ability to detect the hazard. This paper gives a broad summary of technologies that provide users reliable responses to hazardous conditions, that minimise false ...
