£5M Investment In Air Quality
The UK government announced an investment of ~£5 Million to tackle air pollution and one third of all funded applications explicitly mention air quality monitoring or the purchase of air quality sensors. It makes sense: ❔ How do we evaluate the return on the investment? Accurate monitoring of changes in air quality in the target area is needed. ❔ How do we design future ...

Selecting an Airborne Particle Counter: Types of Monitoring (Series Part 2 of 4)
Frequent or Continuous? Frequent Monitoring To demonstrate compliance to ISO, frequent monitoring requires sampling at specified time intervals not exceeding 60 minutes during operation. Manifold systems are the least expensive solution and usually installed during the cleanroom construction process. Standalone particle counters may be installed at any time. A manifold system includes either 16 ...

Air quality management - from traffic management to environmental traffic management
Traffic management systems are commonly used to optimize traffic flow in urban areas, e.g. to prevent traffic congestion. However, the regulation of traffic flows can also be used to control traffic induced emissions and therefore affects air quality. To use a traffic management system as an instrument for the benefit of air quality, the application requires reliable information about the current ...

Facilities Under Positive Pressure
Building pressure is the difference between the outside air supplied to a building and the air removed from inside a building. Typically, a facilities managers are trying to achieve a building with slight positive building pressure, meaning more air is supplied to the building than is removed from the building. Negative Pressure Indicators Negative building pressure means outside air is ...

An intercomparison between automatic and manual methods of measuring hydrogen chloride concentrations in stack releases
1 ABSTRACT The Environment Agency is involved in independent monitoring programmes at a variety of industrial processes where the permits require the measurement of hydrogen chloride (HCl) concentrations in stack releases. The programmes have revealed a number of difficulties associated with the currently used HCl monitoring techniques. Significant differences have been observed between results ...

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 ...

A Case Story: LKAB and Gasmet’s CEMS Cooperation
The European Commission has adopted a number of changes in measurement requirements and emission limits for industrial plants. To limit the environmental impact of iron ore mining, leaders in the industry have been taking the necessary steps to keep track of the emissions their processes produce. LKAB, which specializes in the underground mining and production of iron-pellets, prioritizes the ...

Airborne particle measurements: 100 LPM vs. 1 CFM particle counters in a semiconductor cleanroom environment
Abstract Many current standards define airborne particle monitoring in units of particles-per-cubic-meter (particles/m3). Often, these standards require sampling an entire cubic meter (1 m3) to provide an accurate measurement of airborne particulate levels. Using a conventional aerosol particle counter that samples 1-cubic-foot per minute (1 CFM) requires more than 35 minutes to sample 1 m3. ...

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 ...

EPA establishes new 1-hour standard for sulfur dioxide
On June 2, 2010, the U.S. EPA established a new 1-hour primary National Ambient Air Quality Standard (NAAQS) for sulfur dioxide (SO2). The new 1-hour standard was set at the level of 75 parts per billion (ppb) calculated as the three-year average of the 99th percentile of the annual distribution of daily maximum 1-hour average concentrations. With the establishment of the new 1-hour SO2 standard, ...
