Toshkent shahri mamalakatimizning poytaxti, tez rivojlanayotgan yirik shahar hisoblanadi. Shahar iqtisodiyoti va aholi sonining o‘sishi bilan birga, havoning ifloslanishi holati ham oshmoqda. PM2,5 va PM10 dispers zarrachalari havodagi ifloslanish ko‘rsatkichlaridan biridir. Ushbu maqolada Toshkent shahrining PM2,5 va PM10 dispers zarrachalari bilan ifloslanish darajasi tahlil qilinadi, uning sabablari va salbiy ta’sirlari ko‘rib chiqiladi.Mann-Kendal Testi asosida o‘zgarish dinamikasi statistik tahlil qilindi. Trend test natijasiga ko‘ra, ahamiyatli o‘zgarish PM2,5 uchun 2019-yilda (Z=2.21), 2020-yilda (Z=2.11), 2021-yilda (Z=3.63), 2022 yilda (Z=2.31), va 2023 yilda (Z=3.21 ekanligi aniqlandi, bu natijalar mos ravishda PM10 uchun (Z=2.02) va NO2 uchun (Z=2.26). Ushbu natijalar asosida kelajakda atmosfera havosi monitoringini yuritish bo‘yicha kerakli xulosalar olindi.

Город Ташкент — столица нашей страны и быстро развивающийся крупный город. Вместе с ростом экономики и населения города растет и уровень загрязнения воздуха. Твердые частицы PM2.5 и PM10 являются индикаторами загрязнения воздуха. В данной статье анализируется уровень загрязнения воздуха в городе Ташкенте от PM2.5 и PM10, рассматриваются его причины и негативные последствия. Динамика изменений была статистически проанализирована на основе теста Манна-Кендала. По результатам теста тренда были обнаружены существенные изменения для PM2.5 в 2019 году (Z=2.21), в 2020 году (Z=2.11), в 2021 году (Z=3.63), в 2022 году (Z=2.31) и в 2023 году (Z=3.21), с аналогичными результатами для PM10 (Z=2.02) и NO2 (Z=2.26). На основании этих результатов были сделаны необходимые выводы для будущего мониторинга атмосферного воздуха.

Tashkent city is the capital of our country and a rapidly developing large city. Along with the growth of the city’s economy and population, the level of air pollution is also increasing. PM2.5 and PM10 particulate matter are indicators of air pollution. This article analyzes the level of pollution in Tashkent city from PM2.5 and PM10, examines its causes and negative effects. The dynamics of change was statistically analyzed based on the Mann-Kendal Test. According to the trend test results, significant changes were found for PM2.5 in 2019 (Z=2.21), in 2020 (Z=2.11), in 2021 (Z=3.63), in 2022 (Z=2.31), and in 2023 (Z=3.21), with similar results for PM10 (Z=2.02) and NO2 (Z=2.26). Based on these results, necessary conclusions were drawn for future atmospheric air monitoring.
