  • 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 ...

  • 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 ...

  • A Method of Assessing Air Toxics Concentrations in Urban Areas Using Mobile Platform Measurements

    ABSTRACTThe objective of this paper is to demonstrate an approach to characterize the spatial variability in ambient air concentrations using mobile platform measurements. This approach may be useful for air toxics assessments in Environmental Justice applications, epidemiological studies, and environmental health risk assessments. In this study, we developed and applied a method to characterize ...

  • 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 ...

  • Air pollution and the influence of sources on Paulinia (Brazil) and surroundings

    The air quality in the industrial area and surroundings of the city of Paulinia (state of Sao Paulo, Brazil) has been investigated by analysing the concentration of air pollutants (SO2, PM10, NO, NO2, CO and ozone) and identifying the main sources of air pollution. A mobile pollutant monitoring unit was used to collect the data at five ...

  • Mobile Stationary Source Emissions Testing, Coming to a Facility Near You?

    Last week, Antea Group had the unique opportunity to perform a RATA (relative accuracy test audit) of the emissions from a thermal oxidizer at an ethanol production facility located in Minnesota using a state-of-the-art mobile testing laboratory. During this RATA audit, actual stack emissions levels (including NOx, SOx, CO2, CO, O2, flow rate, temperature, velocity and pressure) from the ...

  • A Comparison of Point Sensors and Open Path Monitors For Toxic Gas (esp. HF) Monitoring

    Point Sensors Ion Mobility Spectroscope (IMS) – a gas sample is ionized by a radioactive source (Ni63). Differences in ion drift under the influence of an applied electric field produce a spectrum that is dependent on the mass, charge, and shape of the component ions. The detector signal and strength is tuned to the drift time of the ion of interest (in this case HF) and signal strength is ...

  • 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 ...

  • 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 ...

  • Simple modelling approaches to assess the impact of traffic air pollution: Cordoba case study

    From 1991 to 1999, there were significant commitments to environmental protection in Argentina. During this period, several important cities of the country, such as Buenos Aires, Cordoba, Mendoza, Bahia Blanca, and Ushuaia, began air quality monitoring programmes. Among these cities, we have taken Cordoba as a case study because of the existence of a continuous monitoring campaign that collected ...

  • MONITORING & ALERT NETWORK in response to the health problems of Sargasso algae

    Martinique has been facing a major health problem in recent years. Indeed, since 2011, the unprecedented phenomenon of massive stranding of Sargasso algae has affected the Atlantic and southern coasts of Martinique. This phenomenon is the origin of a smelling gas emanating from the putrefaction of algae, among these gases hydrogen sulfide (H2S) and ammonia (NH3). Beyond the olfactory discomfort, ...

  • Compressed breathing air safety - how important is it?

    At first glance the physiological demands of the firefighter, the scuba diver and the hospital patient have little in common. One is trained to deal with fire and rescue, one swims underwater and one is concerned with either regaining or improving their health. Yet all three depend to some extent on a safe source of compressed breathing air, which is where our gas detection systems come in. ...
