Abstract
A computer mapping procedure was developed for industrial hygiene data. The computer program was used in conjunction with the jack- knifing variance estimation procedure to generate contour maps. The procedure was used with industrial hygiene data obtained under three conditions: measurements of hexane (110543) and toluene (108883) concentrations in the ambient air of an automobile tire and tube manufacturing factory; noise measurements made at various sites in an airplane hangar; and measurements of total dust concentrations in the ambient air of the automobile tube and tire factory. The actual measurements themselves were used in generating the contour maps for the toluene and hexane exposures in the tube and tire facility, and the noise levels in the hangar. The logarithms of the data were used to generate the contour map for dust exposures in the tire and tube factory. The author notes that although the contour maps represent averages for an 8 hour day, the procedure can also be used to show time lapse changes in exposure.
