Выявлен нисходящий тренд содержания серы и азота, сочетающийся с восходящим трендом величины рН осадков. Среднее сокращение (тренд) за 2002–2019 гг. содержания серы в атмосферных осадках составило 0,019 мг/дм3/год, окисленного азота – 0,008 мг/дм3, восстановленного азота – 0,019 мг/дм3. Изменение содержания серы и азота в осадках привело к сокращению выпадения серы за 18-летний период в среднем на 31,3 кг/км2/год, окисленного азота – на 15,4 кг/км2/год, восстановленного азота – на 25,6 кг/км2/год. Показано, что потенциал закисления природной среды снижался с 2005 по 2012 г. параллельно снижению выпадений серы и азота; в последующий период тренд потенциала закисления в основном следует тренду выпадения основных катионов. Выявлено, что средние за период с 2002 по 2017 г. темпы сокращения содержания окисленной серы и окисленного азота в атмосферных осадках в Минске сопоставимы с темпами сокращения этих соединений на станциях Программы ЕМЕП в Европе, и превышают – для восстановленного азота.</p></abstract><trans-abstract xml:lang="en"><p>The trends in changing the content of sulfur and nitrogen in atmospheric precipitation in the territory of Minsk over an 18-year period are characterized on the basis of the analysis of the monitoring results of the chemical composition of atmospheric precipitation at the experimental site. A downtrend in the sulfur and nitrogen content combined with an uptrend in the precipitation acidity was identified. An average decrease (trend) in the content of sulfur in atmospheric precipitation for 2002–2019 was 0.019 mg S/dm3/year, of oxidized nitrogen – 0.008 mg/dm3, of reduced nitrogen – 0.019 mg/dm3. Over an 18-year period, the changes in the content of sulfur and nitrogen in atmospheric precipitation decreased the deposition of sulfur on average by 31.3 kg/km2/year, of oxidized nitrogen – by 15.4 kg/km2/year, of reduced nitrogen – by 25.6 kg/km2/year. It is shown that for the period from 2005 to 2012, the acidification potential of the natural environment decreased parallel to the reduction of the sulfur and nitrogen deposition; in the subsequent period, the trend of the acidification potential basically follows the trend of the precipitation of the main cations. It is revealed that the rates of average reduction in the content of oxidized sulfur and oxidized nitrogen in atmospheric precipitation in Minsk for the period from 2002 to 2017 are comparable to the rates of reduction of these compounds at the stations of the EMEP Program in Europe, and exceed those for reduced nitrogen.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>атмосферные осадки</kwd><kwd>атмосферные выпадения</kwd><kwd>азот</kwd><kwd>сера</kwd><kwd>закисление</kwd><kwd>эвтрофирование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>atmospheric precipitation</kwd><kwd>atmospheric deposition</kwd><kwd>acidity</kwd><kwd>sulfur</kwd><kwd>nitrogen</kwd><kwd>acidification</kwd><kwd>eutrophication</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Mouli, P.
