In the atmosphere, the acidity of condensed phases (aerosol particles, cloud water, and fog droplets) governs the phase partitioning of semivolatile gases such as HNO3, NH3, HCl, and organic acids and bases as well as chemical reaction rates. It has implications for the atmospheric lifetime of pollutants, deposition, and human health.
13 Οκτ 2023 · Acid deposition occurs when these gases react in the atmosphere with water, oxygen, and other chemicals to form various acidic compounds. The result is a mild solution of sulfuric acid and nitric acid.
Acids and bases: 8.43 - Acid deposition. Syllabus ref: 8.5. Acid rain is a common name for the deposition of acidic material from the atmosphere. This may be either wet deposition of acid in precipitation (rain, snow, or fog), or dry deposition of acidic material on dust, smoke, or small, microscopic particles in the air.
27 Δεκ 2023 · The little data that does exist suggest that \(\alpha\) can vary widely depending upon the aerosol composition (i.e. basic or acidic), relative humidity (i.e. for hygroscopic aerosols, solid particles at low humidity and solution droplets at high humidity), and the nature of the impinging gas.
1 Ιαν 2018 · Acid deposition, often referred to as acid rain, is a term used to describe the deposition of pollutant-derived chemical compounds from the atmosphere to the Earth’s surface. These compounds result from emissions produced by fossil fuel combustion for energy production and vehicular use and from agricultural practices that create air pollution.
26 Οκτ 2015 · In combination with water, oxygen, and other chemicals in the atmosphere, these gases form acid rain, fog, and snow. When acidic wet deposition (pH < 5.6) enters terrestrial and aquatic ecosystems, the dissociation of acid releases hydrogen ions into soils and surface waters, lowering pH and causing a cascade of ecosystem effects.
15 Οκτ 2021 · Given the importance of aerosol particles for the atmospheric energy budget, cloud formation, pollutant deposition, and public health, alkaline species hold the key to control strategies for air quality and climate change.
