ABSTRACT:
A method for detecting and measuring trace amounts of pollutants of the group consisting of ozone, nitrogen dioxide and carbon monoxide in a gaseous environment wherein a sample organic solid material that will undergo a chemical reaction with the test pollutant is exposed to the test environment and thereafter, when heated in the temperature range of 100.degree.-200.degree.C., undergoes chemiluminescence that is measured and recorded as a function of concentration of the test pollutant and wherein the chemiluminescence of the solid organic material is specific to the pollutant being tested.
