Abstract

The correlation between the values of nitrogen dioxide obtained by the alkaline filter paper method and the auto analyser was studied, and it was found that there was a good correlation between two methods. The equations of regression curves were as follows ; In field test : Y=0.3851X+0.0134 In chamber test : Y'=1.2561X'-0.6174 1.00 mg NO2/day/100cm2 (X) obtained by the alkaline filter paper method is equal to nearly 0.40 ppm of nitrogen dioxide concentration (Y) obtained by the auto analyser in the field test.
