Recently developed techniques for sampling and analysis of ambient air by GC/MS/COMP were applied to the Kanawha Valley, WV and Shenandoah Valley, VA to assess the levels of organic pollutants. Volatile and very volatile compounds were concentrated on Tenax GC and carbon sorbent cartridges, respectively, then thermally desorbed directly into the capillary column GC/MS/COMP system for analysis. Semivolatiles were collected on the electrostatic precipitator plates of a Massive Air Sampler, extracted, fractionated, and then analyzed by GC/MS/COMP. The Kanawha Valley contained a broad range of halogenated, ketone, aldehyde, ester, aromatic, aliphatic and polynuclear aromatic compounds. The Shenandoah Valley contained a narrower range of organics, but generally higher observed levels of the compounds quanitated.
