In many places, pollution reaches its peak during the busy summer season. EPA provides a tool to help you make decisions about daily crew activities when the air quality index reaches a certain level.
People with heart or lung disease – including asthma – and all people who are active outdoors are at greater risk from air pollution.
The Air Quality Index is EPA’s color-coded tool for reporting daily air quality and forecasts for common air pollutants, including ozone and particle pollution. It also provides information about simple actions people can take to reduce their exposure to air pollution.
