Он также известен как канцероген для человека и животных. Для оценки пространственно-временной изменчивости содержания формальдегида проанализированы многолетние данные (2003–2016 гг.) измерений спектрометра OMI, размещенного на спутнике Aura. Результаты анализа показали, что тропосферное содержание формальдегида над большей частью территории Беларуси за 2003–2016 гг. имело неравномерное пространственное распределение: наблюдается сокращение концентраций в направлении с юго-запада на северо-восток. Крупные города и промышленные центры образуют зоны повышенного загрязнения тропосферы. Содержание формальдегида в ячейках над территорией Беларуси за период исследования находилось в диапазоне до 30,8×1015 мол./см2 и в среднем составило 6,5×1015 мол./см2. В большинстве полученных значений (84,1 %) концентрации формальдегида фиксировались в пределах 2,0–10,0×1015 мол./см2 и только 0,6 % превысили 15,0×1015 мол./см2. Полученные данные сопоставлены с данными наземной системы мониторинга атмосферного воздуха. Содержание формальдегида в тропосфере над территорией Беларуси, как и в приземном слое атмосферы, носит выраженную сезонную динамику с максимумом в теплый период года с наиболее высокими концентрациями в июле и августе. Анализ внутригодовой динамики содержания формальдегида в приземном слое и в столбе тропосферы свидетельствует о наличии общих тенденций как в целом для Беларуси, так и по отдельным городам.</p></abstract><trans-abstract xml:lang="en"><p>Formaldehyde (HCHO) is a key ingredient in atmospheric chemistry, a precursor to ozone (O3) and an important indicator of atmospheric photochemical activity. It is also known to be a human and animal carcinogen. To assess the spatial and temporal variability of the formaldehyde content, the article analyzes long-term data (2003–2016) of measurements of the OMI spectrometer located on the Aura satellite. The results of the analysis showed that the tropospheric content of formaldehyde over most of the territory of Belarus for 2003–2016 had an uneven spatial distribution: there is a decrease in concentrations in the direction from the southwest to the northeast. Large cities and industrial centers form zones of increased troposphere pollution. The content of formaldehyde in the cells over the territory of Belarus during the study period was in the range of up to 30.8×1015 mol/cm2 and averaged 6.5×1015 molec./cm2. In most of the obtained values (84.1 %), the formaldehyde concentrations were fixed within the range of 2.0–10.0×1015 molec./cm2, and only 0.6 % exceeded 15.0×1015 molec./cm2. The obtained data are compared with the data of the ground-based atmospheric air monitoring system. The content of formaldehyde in the troposphere over the territory of Belarus, as well as in the surface layer of the atmosphere, has a pronounced seasonal dynamics with a maximum in the warm season with the highest concentrations in July and August. An analysis of the intra-annual dynamics of formaldehyde content in the surface layer and in the troposphere column indicates the presence of general trends, both for Belarus as a whole and for individual cities.1</p></trans-abstract><kwd-group xml:lang="ru"><kwd>формальдегид</kwd><kwd>спектрометр OMI</kwd><kwd>атмосферный воздух</kwd><kwd>мониторинг</kwd></kwd-group><kwd-group xml:lang="en"><kwd>formaldehyde</kwd><kwd>OMI spectrometer</kwd><kwd>atmospheric air</kwd><kwd>monitoring</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках Государственной программы научных исследований «Природопользование и экология», подпрограммы «Природные ресурсы и экологическая безопасность»; № госрегистрации 20160130 (2016–2018); № госрегистрации 20192480 (2019–2020)</funding-statement><funding-statement xml:lang="en">The study has been performed within The State Program of Scientific Research «Nature management and ecology», subprogram «Natural resources and environmental safety»; state registration no. 20160130 (2016–2018); state registration no. 20192480 (2019–2020)</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Национальная система мониторинга окружающей среды Республики Беларусь.
