Question

what is land pollution long essay

Answer 1

Hey,
Here is your answer,

Land pollution means degradation or destruction of earth’s surface and soil, directly or indirectly as a result of human activities.
Anthropogenic activities are conducted citing development, and the same affects the land drastically, we witness land pollution; by drastic we are referring to any activity that lessens the quality and/or productivity of the land as an ideal place for agriculture, forestation, construction etc.
The degradation of land that could be used constructively in other words is land pollution.


Causes of Land Pollution-

1. Deforestation and soil erosion: Deforestation carried out to create dry lands is one of the major concerns.

2. Agricultural activities: With growing human population, demand for food has increased considerably. Farmers often use highly toxic fertilizers and pesticides to get rid off insects, fungi and bacteria from their crops.

3. Mining activities: During extraction and mining activities, several land spaces are created beneath the surface.

4. Overcrowded landfills: Each household produces tonnes of garbage each year. Garbage like aluminum, plastic, paper, cloth, wood is collected and sent to the local recycling unit.

5. Industrialization: Due to increase in demand for food, shelter and house, more goods are produced. This resulted in creation of more waste that needs to be disposed of.

6. Construction activities: Due to urbanization, large amount of construction activities are taking place which has resulted in large waste articles like wood, metal, bricks, plastic that can be seen by naked eyes outside any building or office which is under construction.

7. Nuclear waste: Nuclear plants can produce huge amount of energy through nuclear fission and fusion.


Hope this helps.

hey
here's your answer

====================

Land is getting heavily polluted now-a-days by toxic materials and dangerous micro-organisms which enter the air, water and the food chain. The land pollution occurs mainly through centres: namely -



(i) Production centre, and


(ii) Consumption centres.

The produc­tion centres may be further sub-divided into small scale produc­tion centre and large scale production centre or industrial pro­duction centre. The consumption centres contributing solid waste substance may be further divided into individual house, commu­nity centres, markets and municipal garbage centres.”

(A) Sources of Land Pollution:

Land Pollution mainly results from the following sources:

(1) Industrial waste

(2) Urban or commercial wastes,

(3) Agricul­tural wastes;

(4) Municipal wastes;

(5) Chemical and metallic pol­lutants;

(6) Biological reagents;

(7) Hazardous wastes or Radioac­tive pollutants; and

(8) Mining waste.

1. Pollution through Industrial Wastes:

The rapid growth of industries has resulted in the release of a tot of industrial waste on the land surface. The quantity of these wastes depends on the type of raw materials and chemicals used. It has been estimated that nearly 50% of the raw materials ulti­mately become waste products in the industries and about 20% of these wastes are extremely harmful.

The industrial wastes are mainly discharged from pulp and Paper mills, chemical industries, oil refineries, sugar factories, anneries, textiles, steel plant distilleries, fertilizer plants, pesticide industries, coal and mineral mining industries, metal process­ing industries, drugs, glass, petroleum and engineering industries etc.

Besides, thermal, atomic and electric power plants generate fly ash (un-burnt brownish black substance) which severely pollute air, water and land. The industrial wastes may be either organic or inorganic in nature. Also, these may be bio-degradable or non-bio-degradable.

2. Pollution through Urban or Commercial Wastes:

Urban wastes include both commercial and domestic wastes consisting of dried sludge of sewage. The solid urban waste is commonly known as refuse. The refuse contains garbage and rub­bish materials such as plastics, glasses, metallic canes, Fibres, rubbles, street sweepings, fuel residues, containers, abandoned vehicles and other discarded manufactured products.

Urban wastes are even more dangerous than the industrial waste because of their non-biodegradable nature. The leachates from dumping sites and disposal tanks of sewage mixed with in­dustrial effluents and wastes become extremely toxic to living organsims. The leachates coming out of polluted soil contain partly decomposed organic material especially food remnants, vegetables, toxic hydrocarbons and pathogenic bacteria.
