The Use of Diffusive Samplers for Monitoring of Ambient Air

Diffusive monitors have been used for workplace air monitoring for many years, and in many cases have been found to be valid and cost-effective alternatives to conventional pumped or ‘active’ samplers. The state of the art of diffusive sampling is reviewed briefly, with particular reference to workplace air monitoring, and the potential for using similar or adapted devices for measuring concent...

Flow rate measurement in modern ambient air samplers – how accurate ?

New generation ambient air samplers operate at much lower sampling flow rates than do their “high volume” predecessors, namely 16.7 liters/minute. When these new air samplers emerged several years ago there were limited tools available with which to assess and calibrate their operating flow rate. In 1996 a flow meter specifically designed for these new air samplers came available, known as the ...

Characteristics: Ambient Pm10 Samplers

The National Ambient Air Quality Standards (NAAQS) for PM in terms of PM10 are ambient air concentration limits set by the EPA that should not be exceeded. Further, some state air pollution regulatory agencies (SAPRAs) utilize the NAAQS to regulate criteria pollutants emitted by industries by applying the NAAQS as property-line concentration limits. Prior to and since the inclusion of the PM10 ...

Effect based monitoring of seasonal ambient air exposures in Australia sampled by PUF passive air samplers.

There has been relatively little bioanalytical effect based monitoring conducted using samples derived from polyurethane foam (PUF) passive air samplers. Combining these techniques may provide a more convenient and cost effective means of monitoring the potential for biological effects resulting from exposure to complex mixtures in a range of scenarios. Seasonal polycyclic aromatic hydrocarbon ...
