| Abstract |
This article describes a new instrument for aerosol sampling. A commercially-available, high-volume (28.3Lpm) Andersen-type cascade impactor was modified in order to extend its operational range further into the range of large inhalable particles for purposes of use in an exposure assessment study in the primary nickel production industry. The modification involved incorporating a 10ppi (pores per inch) porous plastic foam top stage that has a wide penetration curve with a 50dae-value of approximately 27µm. This enabled the upper end of the range of the instrument to be extended from about 10 to greater than 70µm. A mathematical inversion algorithm developed in earlier research was modified so that it could be applied to this new instrument. The new instrument was deployed in a pilot field study by to demonstrate the potential of the new instrument for generating useful information pertaining to health-relevant aerosol size tractions (e.g., inhalable, thoracic and respirable), and for soluble, sulfidic, metallic, oxidic and total nickel chemical species groups. |
