Air Pollution

Definition

Air pollution refers to the presence of harmful substances in the atmosphere, which can have detrimental effects on human health, the environment, and the climate. It is caused by a variety of sources, including industrial emissions, vehicle exhaust, and natural events like wildfires. This issue is closely linked to sustainability and environmental management as it requires strategies to reduce emissions, protect public health, and promote cleaner technologies.

5 Must Know Facts For Your Next Test

1. Air pollution is responsible for millions of premature deaths each year, with respiratory diseases and heart conditions being the most common health impacts.
2. Major contributors to air pollution include vehicle emissions, industrial discharges, construction activities, and agricultural practices.
3. Particulate matter (PM), nitrogen oxides (NOx), sulfur dioxide (SO2), and volatile organic compounds (VOCs) are some of the key pollutants that affect air quality.
4. Efforts to combat air pollution involve regulations such as the Clean Air Act in the U.S., which sets limits on specific pollutants and encourages states to develop plans to improve air quality.
5. Innovative technologies such as electric vehicles, renewable energy sources, and air filtration systems play a critical role in reducing air pollution and promoting a sustainable future.

Review Questions
