High-value weapons and other technology at those sites are “big, juicy targets for both state and non-state actors,” said Caitlin Lee, a drone warfare expert at RAND in Washington., which presents risks for those breathing it.

The Midwest, Northeast and Great Lakes regions of the U.S. have “very unhealthy” air quality, according to the Environmental Protection Agency, and experts say people should take precautions.The EPA’s Air Quality Index converts all pollutant levels into a single number. The lower the number, the better.

Anything below 50 is classified as “healthy.” Fifty to 100 is “moderate” while 100-150 is unhealthy for “sensitive groups,” and anything above 150 is bad for everyone. The Air Quality Index was aroundSensitive groups include people with asthma, lung disease or chronic obstructive pulmonary disease, said Dr. Sanjay Sethi, chief of the division of pulmonary, critical care and sleep medicine at the University of Buffalo’s medical school.
