Effects of Soil Pollution
1. : Considering how soil is the reason we are
able to sustain ourselves, the contamination of it has major consequences on our
health. Crops and plants grown on polluted soil absorb much of the pollution and
then pass these on to us. This could explain the sudden surge in small and terminal
illnesses.
Effect on health of humans
2. : The ecological balance of any system gets
affected due to the widespread contamination of the soil. Most plants are unable to
adapt when the chemistry of the soil changes so radically in a short period of time.
Fungi and bacteria found in the soil that bind it together begin to decline, which
creates an additional problem of soil erosion.
Effect on growth of plants
3. : The toxic chemicals present in the soil can
decrease soil fertility and therefore decrease in the soil yield. The contaminated soil
is then used to produce fruits and vegetables which lacks quality nutrients and may
contain some poisonous substance to cause serious health problems in people
consuming them.
Decreased soil fertility
4. : The emission of toxic and foul gases from
landfills pollutes the environment and causes serious effects on health of some
people. The unpleasant smell causes inconvenience to other people.
Toxic Dust
5. : The death of many soil organisms (e.g.
earthworms) in the soil can lead to alteration in soil structure. Apart from that, it
could also force other predators to move to other places in search of food.
