Causes of soil pollution With the rise of concrete buildings and roads, one

part of the Earth that we rarely see is the soil. It has many different names, such as dirt, mud and ground. However, it is definitely very important to us. The plants that feed us grow in soil and keeping it healthy is essential to maintaining a beautiful planet. However, like all other forms of nature, soil also suffers from pollution. The pollution of soil is a common thing these days, and it happens due to the presence of man made elements.

Industrial wastes such as harmful gases and chemicals,

agricultural pesticides, fertilizers and insecticides are the most common causes of soil pollution.

Page 4: SOIL  pollution

Waste Disposal Unhealthy waste management techniques,

which are characterized by release of sewage into the large dumping grounds and nearby streams or rivers.

Accidental Oil Spills Oil leaks can happen during storage and transport of

chemicals. This can be seen at most of the fuel stations. The chemicals present in the fuel deteriorates the quality of soil and make them unsuitable for cultivation.

Acid Rain Pollutants present in the air mixes up with the rain

and fall. The polluted water could dissolve away some of the important nutrients found in soil and change the structure of the soil.

Agricultural Activities   Chemical utilization has gone up tremendously since

technology provided us with modern pesticides and fertilizers. They are full of chemicals that are not produced in nature and cannot be broken down by it. As a result, they seep into the ground after they mix with water and slowly reduce the fertility of the soil.

The effects of soil pollution Soil pollution is a result of many

activities and experiments done by mankind which end up contaminating the soil. Some of the main and most important effects are:

Page 10: SOIL  pollution

Health of Humans Rops and plants grown on polluted soil absorb

much of the pollution and then pass these on to us. Foul smell due to industrial chemicals and gases might result in headaches, fatigue, nausea, etc., in many people.

Changes in Soil Structure It is the cause of the death of many soil

organisms (e.g. earthworms)

Page 12: SOIL  pollution

Growth of Plants 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.

Page 13: SOIL  pollution

Toxic Dust The emission of toxic and foul gases

from landfills pollutes the environment.

Page 14: SOIL  pollution

Soil Erosion Loss of soil and natural nutrients present

in it. Plants also would not thrive in such soil, which would further result in soil erosion.

Page 15: SOIL  pollution

Decreased Soil Fertility

The toxic chemicals present in the soil can decrease soil fertility and therefore decrease in the soil yield.

And many more…

We have to remember that…The effects of pollution on soil

are quite alarming and can cause huge disturbances in the ecological balance and health of living creatures on

earth.
