There are
numerous diseases that may be caused by air pollution.
According to the
National Institute of Environmental Health Sciences or NIEHS--a division
of the National Institutes of Health--long-term exposure to air
pollutants boosts a person's risk for respiratory illnesses.
NIEHS notes that children and the elderly are especially vulnerable to
the detrimental health effects of ozone, fine particulate matter and
other airborne toxicants. Pollution-related diseases range from mild to
severe, and can significantly affect a person's quality of
life.
Asthma
Asthma is a
disease that may be caused by air pollution. According to the Natural
Resources Defense Council or NRDC—a non-profit international
environmental advocacy group based in New York City, New
York—asthma is a chronic, occasionally debilitating
inflammatory disease of the airways that may be caused by air pollution
from cars, factories or power plants. The NRDC states that the following
air pollutants are common triggers of asthma: ground level ozone,
sulfur dioxide, fine particulate matter and nitrogen oxide. The Centers
for Disease Control and Prevention or CDC states that another important
trigger for asthma attacks is environmental or secondhand tobacco smoke.
The CDC suggests that parents, friends and relatives of children with
asthma should attempt to quit smoking and should never smoke in
proximity to a child or person with asthma, as this could cause an
asthma attack.
COPD
Chronic
obstructive pulmonary disorder or COPD is a disease that may be caused
by air pollution.
The U.S. National Library of Medicine and the National
Institutes of Health or NIH state that, with COPD, a person's
airways and air sacs lose their shape and become distended or floppy,
and that chronic bronchitis and emphysema are common COPDs. According to
the American Lung Association or ALA, long-term exposure to air
pollution—especially automobile exhaust—boosts
women's risk for lower lung function, COPD and dying
prematurely, and truck drivers, dockworkers and railroad workers may be
more susceptible to lung cancer-, heart- and COPD-related death due to
chronic exposure to diesel emissions while on the job. The ALA also
notes that even low levels of ozone and fine particulate matter increase
a person's risk of hospitalization for pneumonia and COPD.
Lung Cancer
Lung cancer is a
disease that may be caused by air pollution. According to
LungCancer.org, lung cancer is characterized by the uncontrolled growth
of abnormal cells in one or both lungs. Over time, the abnormal cells
can develop into tumors and impair the lung's primary function:
to supply the blood, and therefore the body, with oxygen.
LungCancer.org states that there are two principle types of lung cancer:
non-small cell lung cancer or NSCLC and small cell lung cancer or SCLC.
According to a 2002 study by C. Arden Pope III, Ph.D. and colleagues
published in "The Journal of the American Medical Association,"
long-term exposure to combustion-generated fine particulate matter poses
a significant risk for cardiopulmoary and lung cancer mortality. A 2000
study by Fredrik Nyberg and colleagues published in the journal
"Epidemiology" concludes that urban air pollution boosts lung cancer
risk, and that motor vehicle emissions may be particularly problematic.
