Fine Dust Concentration PM_(10) in the Atmosphere of the City of Kabul, Afghanistan, in Spring Months

摘要

This research work investigates the problem of air pollution with fine dust PM_(10) using the city of Kabul as an example. Data from environmental pollution monitoring data during the transition period of March, April and May has been analyzed. The calculation model for PM_(10) is obtained depending on three factors: wind speed, humidity and air temperature. The dust concentration was described using the theory of stationary random functions. For the maximum daily concentration of PM_(10) in Kabul, estimates of the parameters of the distribution functions were determined, a density function and an integrated distribution function were obtained as well. It is shown that, according to Chi-square and Kolmogorov-Smirnov criteria, the best distribution law of maximum daily concentration of dust is the normal law.
