Air pollution and soiling Two consequences of the dung
remainder are air pollution and soiling. By spreading the dung on the land
heavy metals become free . These metals have a bad influence on the air.
The vapours from the metals rise with hot weather and will get in the air.
When rain falls through that air if will have a relative high acidity.
This water is not only harmful for the environment, but monuments from
for instance limestone and marble will be affected. The surface water will
be affected too, Water life will in that way be influenced. The crops
are the next problem, They will be affected too. The metals ooze
into the ground when it's raining. They sink and sink until they reach
the ground water. In that way the ground water gets dirty, it sustains
heavy metals. When trees drink from the ground water it picks up these
parts and they will be in the tree too. The trees will get sick and they
will die.
