Abstract
Quartz and teflon filter media were evaluated under controlled use conditions to determine their suitability for ambient particulate measurements. Weighing tests and handling tests were conducted in a laboratory environment. A field comparison test in which samples were collected on glass, quartz, and teflon filters was conducted at a typical air quality monitoring site. Total suspended particulate, nitrate, and sulfate concentrations measured during the field comparison test using quartz and teflon filters on high-volume samplers were lower than those measured using glass filters. Observed differences could be explained reasonably well by artifact effects and the aforementioned handling effects. Teflon filters showed a tendency to clog at ambient total suspended particulate concentrations around 75 microgram/cu m.
