Key Concepts

Atmospheric Sinks

Atmospheric sinks are natural systems that absorb, store, or remove gases from the atmosphere, thereby mitigating environmental impacts. Key examples include oceans and vegetation, which play significant roles in regulating the concentration of atmospheric gases through physical, chemical, and biological processes.

Air Pollutants

Air pollutants are substances present in the atmosphere that can harm human health or the environment. They may originate from natural events or human activities and can include a variety of chemical compounds that adversely affect air quality, visibility, and ecological balance.

Air Contaminants

Air contaminants refer to any unwanted or harmful substances in the air that can compromise its purity and may pose risks to both living organisms and the environment. While closely related to pollutants, the term sometimes specifically emphasizes substances accidentally or artificially introduced into the atmosphere.
