The air is a major source of chemicals affecting the health of the Great Lakes. Certain persistent air toxicsPollutants that are known to cause or suspected of causing cancer or other serious health effects, such as developmental effects or birth defects. may contribute not only to atmospheric pollution but to water pollution. These toxics can bioaccumulateThe increase in concentration in living organisms as they take in contaminated air, water, or food because the substances are very slowly metabolized or excreted. in the food web. These sources of pollution may endanger the environment, affecting the health of humans and wildlife. EPA works to inhibit the adverse effects of these chemicals to the public health and the environment.

Integrated Atmospheric Deposition Network (IADN)

IADN is specifically called for in Annex 15 of the Great Lakes Water Quality Agreement. In Canada, these activities are delivered federally through the Great Lakes program. A binational agreement between the U.S. and Canada calls for monitoring the atmospheric deposition of toxic chemicals.

EPA's Clean Air Markets

Clean Air Markets Programs are regulatory programs that improve air quality and public health.

Air Quality and Climate Change

Air quality can be impacted by climate change and, conversely, climate change can impact air quality.
