The Cumulative Frequency Distribution of C+C', where C is a Original Data of Sulfur Oxides and C' is a Constant Value obtained from the curve of Cumulative Frequency Distribution plotted on Log-Normal Probability Paper, shows approximately Log-Normal Distribution.
In order to control air pollutions we have to know the relationship between Annual Mean and percentile value.
In this paper, a fundamental approach is proposed to forcast the Annual Mean, using the movement of the distribution in Log-Normal Probability Paper.
When the Standard value A (ppb) and not exceed frequency below A ppb are proposed as a Environmental Standard, “What's Level of Annual Mean Concentration is acceptable” are discussed.
