While air quality in Broward County falls within the "Good" category about 87% of the time, there are occasionally days where the air quality conditions may become adverse and people - especially children, the elderly, and those with pre-existing respiratory illnesses - may need to take certain precautions.

EnviroFlash is a system that sends e-mails about your daily air quality forecast plus suggested safety measures when levels are unhealthy.

Exposure to high levels of air pollution can aggravate heart disease, asthma and other respiratory diseases. By being aware of the air quality levels, you can take precautions to protect your family.

Air quality monitors take in information that is used to calculate the current Air Quality Index value. Broward County issues air quality forecasts based on measured air quality and weather information. The forecast is then sent out through EnviroFlash.

The Air Quality Index

 

What is the Air Quality Index?

Good (0-50)
Air quality is considered satisfactory, and air pollution poses little or no risk.

Moderate (51-100)
Air quality is acceptable, however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution.

Unhealth for Sensitive Groups (101-150)
Members of sensitive groups may experience health effects. The general public is not likely to be affected.

Unhealthy (151-200)
Everyone may begin to experience health effects. Members of sensitive groups may experience more serious health effects.

Very Unhealthy (201-300)
Health alert. Everyone may experience more serious health effects.

Hazardous (301-500)
Health warnings of emergency conditions. The entire population is more than likely to be affected.

Sensitive groups include active adults, people with heart or lung disease (including asthma), older adults and children.
