    Expert attributes air pollution in Uzbekistan to anthropogenic factors

    Expert attributes air pollution in Uzbekistan to anthropogenic factors

    Air pollution in Tashkent, Uzbekistan, has been identified as predominantly anthropogenic, according to Jay Turner, a professor at Washington University in St. Louis. Turner expressed this opinion during a press conference in Tashkent, as reported by Daryo correspondent in Uzbekistan. He highlighted the need for further research to fully understand the complexities of the issue.

    "An example would be a situation where air quality is worse in winter and appears cleaner in summer. In winter, the air “stagnates” and emissions linger in the atmosphere. Our recent research in Bishkek showed that residents of the capital often use coal to insulate their homes, just like residents of the capital of Mongolia. But this is not your case. Uzbekistan has desert dust, which is especially noticeable in summer and early autumn. This pollen accounts for 25 to 35% of total PM2.5. This indicates the predominance of anthropogenic factors. After all, there is not much (desert) dust in Tashkent," Turner noted.

    "It is noted that the United States is a large country with a diverse geography and different sources of emissions," Turner stated.

    He explained how scientific research in the U.S. helped develop specific strategies to combat air pollution, including the establishment of national standards and municipal requirements for air quality.

    Turner emphasized the importance of open data on air pollution, particularly regarding dangerous fine particles like PM 2.5, which have adverse effects on human health, especially the cardiovascular system. He underscored the significance of air quality monitoring, mentioning the installation of an air quality sensor at the U.S. Embassy in Tashkent.

    "The biggest problem with PM 2.5 is the fine particles, which lead to heart problems rather than breathing problems. This is the most powerful effect on health," Turner summarized.

    He also highlighted the risks posed by ultrafine PM 1 particles, which penetrate deep into the lungs and bloodstream.

    The data from the U.S. Embassy's monitoring system is crucial for understanding regional pollution levels. However, it cautioned that differences in calculation methods might result in variations between AQI figures published by Uzhydromet and data from AirNow.gov.

    Earlier Daryo reported that the Angren thermal power plant faced fines exceeding $40,000 for air pollution violations.
