heal.abstract	Laboratory kinetic experiments can be performed under conditions of concentration, temperature, pressure, humidity, and so on very close to those prevailing in the atmosphere and in the presence of heterogeneous sinks by the reversed-flow gas chromatography (RF-GC) technique. It is an absolute rate constant technique, but the system is neither a static nor a flow one. It is a diffusion controlled system by means of which rate constants and reaction orders with respect to time n(t) of unimolecular and bimolecular chemical reactions of atmospheric species with other substances can be measured. In the presence of heterogeneous sinks, the following physicochemical parameters are determined under unsteady-state conditions: the local adsorption parameter k(1) of the analyte A under study and the experimental isotherm, the desorption rate constant of A from the solid surface k(-1), the rate constant k(2) of a possible first-order or pseudo-first-order surface reaction of the adsorbed analyte, and the deposition velocity V-d and the reaction probability gamma of A on the heterogeneous sink.
