Measurement and Modeling of Airborne Concentrations and Indoor Surface Accumulation Rates of Ionic Substances at Neenah, Wisconsin.
01 January 1990
The objective of this continuing investigation of indoor/outdoor/surface relationships has been to develop an accurate method for predicting and subsequently managing the accumulation rates and ultimately the effects of corrosive substances on electronic equipment surfaces in field and manufacturing environments. We previously reported deposition velocities for chloride, sulfate, sodium, ammonium, potassium, magnesium, and calcium associated with fine and coarse particles at telephone company switching equipment locations in Wichita (Kansas), Lubbock (Texas), and Newark (New Jersey). These results were based on comparisons of indoor concentrations, obtained using dichotomous samplers for collection and ion chromatography (IC) for analysis, with surface accumulation rates that were obtained by collecting water extracts of surfaces and then analyzing by IC.
