Background information and definitions
Atmospheric pollutants can be removed from waste gases (e.g. from industry or transport) before they enter the environment. Physical or electrostatic filters can trap dust and ash particles. Sulfur dioxide can be removed by spraying alkaline substances, such as seawater, into waste gases. Reducing emissions of atmospheric pollutants may prevent damage to marsh or swamp vegetation, or allow it to recover. Ultimately, efforts to clean up waste gases may be driven by legislation or financial incentives.
