  • 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 ...

  • 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 and Emissions Monitoring: What does best practice look like?

    When we turn on the tap, we know that the water coming out should be of a consistently high quality. And we can choose – if we prefer – to drink bottled water instead. This is not so with the air that we breathe. Unlike the water that we drink, we have no guarantee, and in many cases no information, telling us that the air quality in our towns, cities and even rural areas is of an ...
