Exposure to indoor
and outdoor air
pollutants can
cause health
effects ranging
from coughing and
sneezing to
outcomes such as
exacerbation of
chronic respiratory
disorders such as
asthma in pre-
teens
Indoor air pollution
hazards
Excess moisture,
volatile organic
compounds, carbon
monoxide, and radon
are four main indoor
air contaminants,
according to the
Environmental
Protection Agency.
Houses get moist and
stuffy as a result of
them.
outdoor air pollution
hazards
The common sources of
outdoor air pollution are
emissions caused by
combustion processes
from motor vehicles,
solid fuel burning and
industry. Other pollution
sources include smoke
from bushfires,
windblown dust, and
biogenic emissions from
vegetation (pollen and
mould spores).

How does it cause
asthma in pre-teens
Air pollution has the
same effect on
asthmatic children as
other factors. They
irritate the airways,
causing them to enlarge
and tighten, resulting in
breathing difficulties.
Pollutants can also
make children more
susceptible to upper
respiratory infections
(such as colds), which
can exacerbate asthma
symptoms.
Possible precautions
to take
check the air quality
index and try to
improve it
refer to a physician
about increasing the
medicine when air
pollution is high
follow the
asthma action
plan for your
child
