Aerosols are tiny solid particles or liquid droplets suspended in the air. Aerosol emission refers to the release of these particles into the atmosphere. These emissions can originate from both natural sources and human activities. Natural sources include volcanic eruptions, dust storms, sea spray, and forest fires. Human-generated aerosols, often referred to as anthropogenic aerosols, are a significant contributor to air pollution and atmospheric composition.

Major anthropogenic sources of aerosols include the burning of fossil fuels in power plants and vehicles, industrial processes such as manufacturing and mining, and agricultural practices like tilling and fertilizer use. Biomass burning, including the burning of wood for heating and cooking, is also a substantial source, particularly in certain regions. Aerosols can be directly emitted into the atmosphere (primary aerosols) or formed in the atmosphere through chemical reactions of gases (secondary aerosols).

The impact of aerosol emissions on the environment and human health is diverse. Aerosols can affect climate by scattering or absorbing solar radiation, influencing cloud formation, and altering precipitation patterns. Some aerosols, like black carbon, absorb sunlight and contribute to warming, while others, like sulfates, reflect sunlight and have a cooling effect. Regarding health, inhaling fine particulate matter can lead to respiratory and cardiovascular problems, exacerbating existing conditions and contributing to premature death. Understanding and controlling aerosol emissions are therefore crucial for both climate mitigation and public health initiatives.
