PARTICLE


DICTIONARY


Smog has five main ingredients,
which combined into a toxic
cocktail. The tiny particles and
harmful gases of the polluted air
enter deep into the lungs, where they
could cause anything from mild
inflammation in the body to much
more severe conditions such as
dementia and diabetes.

Lab experiments indicate
that lengthy exposure to NOX
causes inflammation in
the body, but the long-term
effects are still
unknown.

O 3 or ozone pollution harms
the respiratory passages and
could cause anything from
breathing difficulties to a
long series of chronic
lung diseases such
as KOL.

NH 3 or ammonia pollution is
not a health problem in itself,
but it produces harmful
particles, when it
combines with SO 2 ,
NOX, etc.

O 3


NH 3


NOx


PM is short for “particulate
matter” such as soot and
fine dust. It can enter deep
into the lung tissue and
cause too early death.

PM


Mostly from power
plants, but also from
volcanoes, dust storms,
and fire.

Is primarily from
diesel cars and coal-
fired power stations.

Is primarily from farm
animals and the use
of fertiliser.
