Fig. 5.Visualizing map profiles of representative volatile organic compounds at their IDLH and PEL concentrations. For purpose of visualization, the color range of these
maps is expanded from 4 (blue frame) or 7 (green frame) bits to 8 bits per color (RGB range of 2–17, 20–147 to 0–255). For weakly responding VOCs, RGB range of 0–5 (red
frame) is expanded to 0–255. (For interpretation of the references to color in thisfigure legend, the reader is referred to the web version of this article.
