Outdoor Air Quality Standards

Outdoor Air Quality Standards are guidelines set by health and environmental authorities to maintain healthy air for everyone. They specify acceptable limits for pollutants like smog, carbon monoxide, sulfur dioxide, nitrogen dioxide, ozone, and particulate matter. These standards aim to prevent health problems, especially for sensitive groups such as children and the elderly, and to protect ecosystems. Monitoring air quality helps ensure these limits are not exceeded, guiding policies and actions to reduce pollution and improve overall air health. They are essential for safeguarding public health and the environment.
