Answers
Explanation:
CAUSES OF SOIL POLLUTION - DEFINITION
Soil pollution can be caused by the following-
Drilling of oil refineries
Accidental spills
Acid rain (which is caused by air pollution)
Intensive farming
Deforestation
Genetically modified plants
Nuclear wastes
Industrial accidents
Landfill and illegal dumping
Land erosion
Agricultural practices, such as application of pesticides, herbicides and fertilizers
Mining and other industries
Oil and fuel dumping
EFFECTS OF SOIL POLLUTION - DEFINITION
Effect on health of humans: Considering how soil is the reason we are able to sustain ourselves, the contamination of it has major consequences on our health.
Effect on growth of plants: The ecological balance of any system gets affected due to the widespread contamination of the soil.
Decreased soil fertility: The toxic chemicals present in the soil can decrease soil fertility and therefore decrease in the soil yield.
Toxic dust: The emission of toxic and foul gases from landfills pollutes the environment and causes serious effects on health of some people.
Changes in soil structure: The death of many soil organisms (e.g. earthworms) in the soil can lead to alteration in soil structure.
PREVENTION AND CONTROL MEASURES OF SOIL POLLUTION - DEFINITION
The following measures should be taken to prevention of soil pollution-
1. Use of pesticides should be minimized.
2. Use of fertilizers should be judicious.
3. Cropping techniques should be improved to prevent growth of weeds.
4. Special pits should be selected for dumping wastes.
5. Controlled grazing and forest management.
6. Wind breaks and wind shield in areas exposed to wind erosin.
7. Planning of soil binding grasses along banks and slopes prone to rapid erosin.
EFFECT OF SOIL POLLUTION - DEFINITION
Soil pollution affects human beings and animals indirectly through food chains. The effects of soil pollution on environment, human health and other organisms are discussed below.
(i) Land and soil pollution is responsible for loss of fertility and productivity of soil.
(ii) Soil contains many pathogenic bacteria, viruses and intestinal worms which are transmitted to man by the consumption of fruits and vegetables. These pathogens cause various types of diseases.
(iii) Many pesticides are absorbed by plants and reach animals and humans via food chains.
