What is defined as atmospheric deposition?

Atmospheric deposition is specifically defined as the transfer of pollutants from the atmosphere to Earth's surface. This process can occur through various mechanisms, including precipitation, where pollutants are carried down with rain or snow, and other forms of fallout, such as dust or smoke settling directly onto land or water surfaces. This transfer plays a significant role in environmental pollution as it can impact soil quality, water bodies, and vegetation by introducing harmful substances. Understanding atmospheric deposition is crucial for assessing air quality and its subsequent effects on ecosystems and human health.
