  I would like to dedicate this report to one of the most troubling topics for the people of Uzbekistan. Even though the situation has now improved, but at the time of the incident, it was alarming to observe the situation. The fact is that on the evening of November 4, the Tashkent region and some other regions of Uzbekistan were covered by a dusty-sandy haze. The amount of dust in the atmospheric air exceeded the norm five times. A dust storm is an atmospheric pressure, which is the transfer of large quantities of dust from the surface of the earth by the wind. In the beginning, no one realized what was happening and many thought it was a fog, as it was the first time we had encountered such a situation in 170 years. As reported later, it turned out that cold air from the regions of the Urals had invaded the territory of the republic. The wind picked up to 12-15 m/s in the cold front zone, and up to 20-25 m/s in Bukhara, Navoi and Jizzak regions. Under the influence of wind gusts strongly dried up the top layer of soil, creating the effect of dusty-sandy haze with deterioration of visibility in some areas of the country up to 500-1000 meters. According to the chief doctor of the Tashkent City Ambulance Station, while on November 3, 3,433 people sought help, on November 4 there were 4,082. Thomas Gill said that if the measurements are correct, these are indeed extreme and extremely dangerous levels of particulate matter for urban areas. The U.S. Environmental Protection Agency's 24-hour average limit, for example, is 150 micrograms per cubic meter for dust. So these levels in Uzbekistan are about four times worse than he ever saw in El Paso. These may be some of the highest values for dust pollution ever measured for ambient air in urban areas. As the negative impact of environmental hazards in the country intensifies, the dust storm that has occurred further confirms it. The situation related to the drying up of the Aral Sea is becoming more and more acute.
