The effect of ambient ozone and humidity on the performance of nylon and Teflon filters used in ambient air monitoring filter-pack systems

Year: 2010

Type: article

Abstract: Nylon and Teflon filter media are frequently used for monitoring ambient air pollutants. These media are subject to many environmental factors that may influence adsorption and retention of particulate and gaseous nitrogenous pollutants. This study evaluated the effects of ozone and humidity on the efficacy of nylon and Teflon filters used in the US dry deposition monitoring network. Ozone was shown to reduce retention of nitric acid on nylon filters and high humidity was shown to dramatically increase retention on nitrate on Teflon filters.
