Isocyanate-containing compounds are used in the production of a wide variety of surface coatings, polyurethane foams, adhesives, resins, elastomers, binders, and sealants. Examples of potential worker exposures to isocyanates in automobile painting and mining applications are shown in Figure 1. Selecting the most appropriate sampling and analytical methods for isocyanates in a specific workplace environment is difficult for the following reasons: Isocyanates may be in the form of vapors or aerosols of various particle sizes: the species of interest are reactive and, therefore, unstable: pure analytical standars exist only for monomeric isocyanates and low limits of detection are needed.
