Analysis of peak exposure to chemicals is very important for clarifying the health effects of high short-term exposure. Preller et al. (2004)Go obtained exposure data from various industries where spraying was used, and found five measures characterizing peak exposure. In general, the profile of variation of exposure concentration is expressed using distribution and autocorrelation. Distribution of exposure concentration is described as log-normal, which is expressed by two parameters: geometric mean (µg) and geometric standard deviation ({sigma}g). µg and {sigma}g represent exposure intensity and . . .
