A continuous monitoring method and system wherein a porous substrate or film is used. The air from the environment is drawn through a region of the porous substrate by a simple air pump and the substances in the air are deposited or chemically adsorbed onto the surface of the substrate. The region of the substrate where the environmental air is drawn through is continuously monitored by an optical or spectrometric method. The substrate is in the form of a tape supplied by a feed reel in a reel-to-reel cartridge and taken up by a take-up reel as found in a film cartridge or a magnetic tape cartridge. The cartridge can be replaceable. A variety of materials may be employed as the substrate with an adequate surface area to effect accumulation of solid, liquid, aerosol, or gas phase compounds. An optical interrogation system is engineered such that the surface of the tape at the point where air from the environment is drawn through the substrate becomes the interaction region between the source output and the sample. As material from the environment accumulates in this region, the interaction of the source with the material is monitored by a suitable detector and supporting circuitry.
