that can aggravate asthma.
3.
__________ of American children live in areas that regularly exceed the U.S. EPA’s limits for
ozone.
4.
More than 25% of the ozone pollution comes from _______________.

responsible for nearly __________ of the global burden of disease.
6.
Nearly _____ million children younger than 5 years of age die every year from acute
_______________ infections.
7.
Air quality is related to the incidence and severity of _______________, heart and
_______________ diseases, allergies, and several types of _______________.
8.
Indoor air is most affected by pollutants caused by _______________ and _______________,
which releases particulates and _______________, and by tobacco use, outdoor quality,
_______________, rodents, and insects.
9.
Outdoor air problems largely involve _______________ sources such as factories and
_______________, and fossil fuel burning for transportation and _______________ production.
10.
Some of the outdoor pollutants of concern include particulates, carbon dioxide,
_______________, and lead.
11.
Greenhouse gases released by combustion of _______________ are a primary cause of global
warming.
12.
There are many sources of pollution in our water. In addition to point sources such as
_______________ and industrial waste, a great deal of water pollution comes from _______________
sources such as agricultural runoff, and _______________ drainage.
