Validation of a new method for in-stack measurement of particulate matter emissions from large stationary sources
Abstract A new method for measuring particulate matter in stationary sources has been developed by Rupprecht & Patashnick Co. (R&P). This new method, named the TEOM® Series 7000 Source Particulate Monitor, uses R&P TEOM technology to provide in situ, filterbased, direct mass measurement of particulate matter in stationary source emissions. The performance of this new monitoring ...

TSI dust monitors and Lufft weather sensors make a great team
Both aerosols and wind speed and direction influence air quality significantly. This is why TSI Incorporated, a world leader in particle measurements, cooperates with Lufft USA in order to provide complete systems to measure PM2.5 (fine dust), PM10 (particles with a maximum diameter of 10 μm) as well as total PM levels. TSI Incorporated offers a variety of aerosol monitors for real-time, ...

Measuring Opacity and Particulate Matter
Among the most obvious of hazardous air pollutants (HAPs), as it is readily visible by eye, is particulate matter (PM) - particles of smoke and dust. Small particlesbelow 2.5 μm in diameter are a special concern as they pose the greatest risk to health. Some PM emissions can be categorised as fugitive and are generally subject to work practice controls. However, the main sources of emissions ...

Frequency distribution of particulate matter (PM10) in urban environments
Hourly measurements of particulate matter with an aerodynamic diameter less than 10 µm (PM10) were recorded in Athens, Greece and Manchester, UK, for a period of one year. The lognormal, gamma and Weibull distributions were selected to fit the concentration frequency distribution of the measured PM10 data. Moreover, the statistics of Mean Bias Error (MBE), Root Mean Square Error (RMSE) and index ...

Differential impacts of smoke-free laws on indoor air quality
The authors assessed the impacts of two different smoke-free laws on indoor air quality. They compared the indoor air quality of 10 hospitality venues in Lexington and Louisville, Kentucky, before and after the smoke-free laws went into effect. Real-time measurements of particulate matter with aerodynamic diameter of 2.5 µm or smaller (PM2.5) were made. One Lexington establishment was excluded ...

AMETEK Land reveals how power plants can better monitor their emissions
AMETEK Land reveals in its latest engineering brief how power plant operators can benefit from opacity monitoring systems to verify that they are compliant with global and national emissions limits. The brief, which is available at landinst.com, outlines how power-generation plant operators must measure either particulate matter (PM) and/or opacity, and monitor and report measurement results ...

Airborne chemical elements: correlation between atmospheric levels and lichen content
Concentrations of As, Cd, Co, Na, Sb, Se and Zn have been measured in atmospheric particulate matter and Parmelia sulcata Taylor transplants at a suburban and industrial area. Levels in particulate matter were found to be much lower than European target values, Californian Acute Inhalation Reference Exposure Levels and Ontario's Ambient Air Quality Criteria. Correlations between elemental content ...

German Advisory Council on the Environment (SRU) hands over its Environment Report 2008
The 1000 pages report 'Environmental protection in the shadow of climate change' is an overall assessment of German and EU environment policies. The statements in Chapter 4 - Clean Air - are based amongst others on two reports, worked out by IVU Umwelt, commissioned by the German Federal Environmental Agency (UBA): Diegmann, V., Pfäfflin, F., Wursthorn, H. (2007a): Updated inventory of Clean Air ...

Air pollution in China disrupts flights
You know you have a problem when the smog gets so bad even airplanes can’t land safely anymore. This is what happened last month, when an airplane coming from Japan had close to zero visibility as it was trying to land in Beijing. There was thick smog blanketing the city. It was so bad that the plane requested permission to land at two alternative airports. However, permission was ...

Criteria and Air-Toxic Emissions from In-Use Automobiles in the National Low-Emission Vehicle Program
The U.S. Environmental Protection Agency (EPA) implemented a program to identify tailpipe emissions of criteria and air-toxic contaminants from in-use, lightduty low-emission vehicles (LEVs). EPA recruited 25 LEVs in 2002 and measured emissions on a chassis dynamometer using the cold-start urban dynamometer driving schedule of the Federal Test Procedure. The emissions measured included ...
