Gas-phase reaction between hydroxyl radical and sulfur dioxide worsens air quality.
Sulfate aerosols in the atmosphere can harm air quality and ecosystems. Scientists studied how sulfur dioxide reacts with hydroxyl radicals to form sulfate aerosols. They found that this gas-phase reaction contributes to about 30% of sulfate in the air over the West Pacific region. This new method helps understand how sulfate aerosols are formed and their impact on the environment.
