There are many health effects from exposure to
particulate matter. Numerous studies have showed
associations between exposure to particles and
increased hospital admissions as well as death
from heart or lung diseases. To learn more about
the air quality index.

Ozone in the upper atmosphere protects us by
filtering out damaging ultraviolet radiation from
the sun. Effects from exposure to ozone are
Irritation and inflammation of eyes, nose, throat
and lower airways coughing, sore and scratchy
throat or uncomfortable feeling in chest, not
able to breathe as deeply or vigorously as you
normally would. It can be Increased
susceptibility to respiratory infections.

Outdoors, nitrogen dioxide contributes to the
formation of ground-level ozone (O3) as well as
particulate matter pollution. Nitrogen dioxide is
a respiratory irritant and has a variety of
adverse health effects on the respiratory system.
It can be Increased susceptibility to lung
infections in people with asthma, Worsened
symptoms of asthma more frequent asthma attacks
and Airway inflammation in healthy people.
5
Carbon monoxide can cause harmful health effects
by reducing the amount of oxygen reaching the
bodys organs (like the heart and brain) and
tissues. At extremely high levels, carbon
monoxide can cause death (carbon monoxide
poisoning). Chest pain in people with coronary
heart disease and Potentially serious health
effects on unborn babies when exposed to high
levels.

Sulphur dioxide irritates the lining of the nose,
throat and lungs and may worsen existing
respiratory illness especially asthma. It has
also been found to exacerbate cardiovascular
diseases.
