| Abstract |
An attempt was made to develop a personal monitor to measure nitrogen dioxide. Sampling of nitrogen dioxide is accomplished by permeation through a silicone membrane into a alkaline thymol blue solution. The nitrogen dioxide is converted to nitrite and is then quantitated by colorimetric analysis. Since collection of the nitrogen dioxide through the silicone membrane depends only on permeation, maintenance of carefully measured sampling rates are not required. A small scale field evaluation of this method with the accepted EPA-TGS-ANSA equivalent method for NO2 showed that the personal monitor gave much higher results. This difference must be resolved before this personal monitor can be considered as a viable equivalent method for nitrogen dioxide. |
