On the Calculation Model of Fine Dispersed Dust Pollution of Kabul's Atmosphere for Ventilation Design

Abstract:

The paper presents the results of the assessment of atmospheric air pollution with fine dust РМ₁₀ studies in the city of Kabul_. The investigation was based on concentration of fine dust РМ₁₀ measurements that were conducted by the national agency on ecology and environmental protection of Afghanistan and by Russian researchers in summer and autumn of 2015. It is shown that, according to the Chi-square and Kolmogorov-Smirnov criteria, the best law for the distribution of the maximum daily dust concentration is the logarithmic normal law. For the maximum daily concentration (РМ₁₀) a density function and an integrated distribution function have been summarized. A mathematical model of the concentration of fine dust (РМ₁₀) dependence of three factors: wind speed, humidity and temperature have been obtained. On the basis of F–Fisher criterion the quadratic model has been chosen for June and August, and the linear model has been chosen for July, September, October and November.
