  • Comparison of two standard odor intensity evaluation methods for odor problems in air or water

    Government agencies responsible for ensuring healthful water and/or air quality are often faced with resolving public complaints of nuisance odors. Understanding variations in odor intensity may ultimately lead to the establishment and application by such agencies of quantitative limits for effective odorant control. An odor panel was trained in suprathreshold odor intensity evaluation using ...

  • New NO2 air standards prove technically challenging

    On February 9, 2010, the U. S. Environmental Protection Agency (EPA) established a new National Ambient Air Quality Standard (NAAQS) for nitrogen dioxide (NO2). The new NO2 NAAQS is a one-hour standard set at 100 parts per billion (ppb), which is approximately 188 micrograms per cubic meter (μg/m3). Effective on April 12, 2010, the new one-hour standard is intended to protect against peak ...

  • 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 ...

  • AQMesh: a new option for flexible air quality monitoring

    AQMesh has an impressive collection of global users and performance results measuring ambient air quality in applications ranging from traffic planning and urban hotspots to industrial fence line monitoring, building ventilation management, or environmental lobbying. This pole-mounted unit comes with an independent power supply and communications, so offering the possibility of measuring air ...

  • 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 ...

  • Air quality issues drive vehicle alternatives

    Vehicle exhaust systems remain a major source of air pollution in cities, despite the progress being made to reduce emissions from new models. Energy World takes a look at efficiency improvements, and the alternative fuel alternatives to petrol and diesel. In early April, the south of Britain woke to a hazy blanket of smog. A few weeks earlier, Paris had choked and spluttered through its own ...

  • Ground Zero Air Quality Has A Long Way To Go! A Summary of Air Quality Testing in Surrounding Buildings

    There are still a wide range of concerns about air quality in the vicinity of Ground Zero. Many commercial and residential spaces have yet to be re-occupied. In only a few cases has any sort of inspection or testing been done to determine if they are safe to occupy. The greatest concerns are asbestos and the very irritating concrete dust that spread throughout lower Manhattan during the collapse ...

  • Methods for the control of oil vapour emissions

    There are many oil vapours to discharge from oil containers into the atmosphere in oil operations (such as storage and loading). Two basic concepts are discussed regarding the control of oil vapour emission (OVE). The first is to invent active methods to restrain the OVE. The second is to develop passive tail–end remediation technologies to control the released vapour. Oil vapour recovery ...

  • From air conditioning to urban planning, defaults and standards create dysfunction by design

    How can we stop outdated assumptions from forcing us to waste? Personal heaters are a summer survival tool for many office workers chilled to the bone by hyperactive ventilation systems — an act of self-defense against an epidemic of overcooling that is wasting energy and confounding comfort in not only offices but also large shops, schools and other buildings. An audit ...

  • Minimising Risks to Air Quality and Regulatory Compliance With Total Filter Management

    It has been shown in recent studies that as much as 25% of the total site operating budget (excluding raw material costs) for a typical medium-large dosage-form manufacturing facility will be spent on compliance measures for internal quality systems and external regulatory activities. (1) Market realities indicate that the pharmaceutical companies will need to address the overall cost of ...
