| description | <p>Atmospheric ammonia (NH<span class="inline-formula"><sub>3</sub></span>) is a key transboundary air pollutant that contributes to the impacts of nitrogen and acidity on terrestrial ecosystems. Ammonia also contributes to the atmospheric aerosol that affects air quality. Emission inventories indicate that NH<span class="inline-formula"><sub>3</sub></span> was predominantly emitted by agriculture over the 19th and 20th centuries but, up to now, these estimates have not been compared to long-term observations. To document past atmospheric NH<span class="inline-formula"><sub>3</sub></span> pollution in south-eastern Europe, ammonium (NH<span class="inline-formula"><math xmlns="http://www.w3.org/1998/Math/MathML" id="M4" display="inline" overflow="scroll" dspmath="mathml"><mrow><msubsup><mi/><mn mathvariant="normal">4</mn><mo>+</mo></msubsup></mrow></math><span><svg:svg xmlns:svg="http://www.w3.org/2000/svg" width="8pt" height="15pt" class="svg-formula" dspmath="mathimg" md5hash="310866e2e55ea172cf2d52bb7208ba35"><svg:image xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="acp-25-1385-2025-ie00001.svg" width="8pt" height="15pt" src="acp-25-1385-2025-ie00001.png"/></svg:svg></span></span>) was analysed along an ice core extracted from Mount Elbrus in the Caucasus, Russia.
