Environmental chambers have been extensively used in
atmospheric chemistry studies. Grosjean (1985) have measured loss rates for 20 gaseous pollutants in FEP Teflon
Chambers including nitric acid, nitric oxide, nitrogen dioxide, PAN and methyl nitrate which are determined by
a chemiluminescentdetector based on the NO/O3 reaction.
For oxides of nitrogen, the measured loss rates reflected
the competing pathways of thermal oxidation of NO
(dark), photolysis of NO2 (sunlight), loss of NOx and
loss of products to the walls, and heterogenous hydrolysis
of NOv
