"Today, nearly 30 million adults and children in the United States have been diagnosed with
asthma. Asthma sufferers can be severely affected by air pollution. Air pollution can also
aggravate health problems for the elderly and others with heart or respiratory diseases."
"It can irritate your throat and make breathing difficult. In fact, pollutants like tiny
airborne particles and ground level ozone can trigger respiratory problems, especially for people
with asthma. "
At "Unhealthy" AQI levels, everyone may begin to experience some adverse health effects, and
