Abstract
A new method for determining the PMI 0 concentrations has been developed. It is called the I-fiVol/Coulter process and involves using the high volume sampler (HVol) and the Coulter Counter particle size distributions. PMIO concentrations are typically determined using samplers approved by the EPA, such as the Wedding samplers. These samplers have a device that separate particulate matter larger than 10jim aerodynamic equivalent diameter prior to filtration. With the FEVol/Coulter method, it is possible to determine PMIO concentrations using total suspends particulate (TSP) measured with a HVol sampler and utilizing a particle size distribution determined with a Coulter Counter Multisizer. This procedure was developed to more accurately determine PMIO concentrations using standard high volume samplers and the Coulter Counter Multisizer. The FEVol/Coulter method can be used to calculate TSP, PMIO and PM2.5 using just one exposed filter. It will assist in regulating PMIO air pollution and can be extended to estimate PNU. 5 concentrations in the future.
