Sources and Causes of land pollution Land pollution is caused by both natural factors and human activities. They are each discussed below: The natural factors that cause soil erosion includes volcanic eruptions, changes in rainfall pattern, earthquakes, topographic changes, wind and glacier movements. Natural factors of soil erosion like rainfall, wind, topography, etc.
Pollution through Chemical and Metallic Pollutants: The industries like textiles, paints, dyes, soap and synthetic detergents, tanneries, drugs, batteries, cement, asbestos, rubber, petroleum, paper and pulp, sugar, steel, electroplating and metal industries release harmful effluents in soil and water creating hazards in living world.
When soil is found to be complexed with organic chemicals and toxic metals or its ions, these affect the soil texture, its fertility and stabilization of soil organic matter. Excess of sulphur in soil may be absorbed by plant leaves as SO2 injuring plant tissues.
The presence of high concentration of Mg, Fe, Zn and V, causes lethal effects on crop production. Digested sewage sludge heavy application of manure to soil, causes chronic salt hazards to plants.
Pollution by Biological Agents: The major source of land pollution by biological agents comes from the excreta of human beings, animals and birds.
The soil is residence of a number of bacteria, fungi, algae, protozoans, actinomycetes, nematodes, rotifiers etc. These modulate soil fertility and soil texture. Besides, these attack the different part of the plant, specially the roots, causing significant damage. Human excreta contain pathogens such as enteric bacteria and parasitic worms, which reside in soil.
These organisms enter into human body either via food chain or by direct contact with contaminated soil.
The sanitary habits of people help in the repetition of the cycle of infection with soil transmitted pathogens from man to soil and then from soil to man. This class includes pathogenic bacteria and parasitic worms excreted from animals.
These organisms are transmitted from animals to soil and then from soil to man. Hazardous Wastes Radioactive Wastes: Radioactive waste contains several radio nuclides Such as Ceasium, Strontium, Todine and Tsotopes or Radioactive elements.
Pollution through Mineral Wastes: During mining operations, huge quantities of wastes are dumped on land surface.
For example, during mining of metal ores, huge quantities of earthen materials, rocks and other wastes are created. Thus huge quantity of waste mining materials is created which not only occupy valuable land surface but also create nuisance due to the presence of toxic chemicals. B Detrimental Effects of Land Pollution: Now let us discuss the effect of land pollutants from different sources on man, animal and vegetation.
Effects of Industrial Pollutants: Industrial wastes containing toxic metals e. Heavy metals precipitate phosphatic compounds and catalyse their decomposition. Industrial wastes containing soluble salts cause crop loss, soil loss, metallic corrosion etc.
Industrial effluents causing high acidity or high basicity of the soil cause severe agricultural crop damage. SO2NOx etc. Some industrial wastes also contain pathogenic bacteria, which cause significant health hazards. For example, the pathogen Anthrox bacilli are present in tannery waste.
Effects of Urban Wastes:Land pollution is caused by both natural factors and human activities. Natural factors: The natural factors that cause soil erosion includes volcanic eruptions, changes in rainfall pattern, earthquakes, topographic changes, wind and glacier movements.
Petroleum refineries also release hydrocarbons and various other chemicals that pollute the air and also cause land pollution. 4. Another direct effect is the immediate alterations that the world is witnessing due to Founded Conserve Energy Future with the sole motto of providing helpful information related to our rapidly depleting.
What is Land Pollution? or modification of the original properties of the land to make it use-worthy for a specific purpose is another major cause.
This hampers the land immensely. Also there is a constant waste of land. Effect on human health: The land when contaminated with toxic chemicals and pesticides lead to problem of skin cancer.
Pollution not only damages the environment, but damages us also. Pollution is the cause of many problems ranging from lung cancer to the greenhouse effect. Though pollution is all among us, we continue to live in our own filth and do nothing to better the environment around us.
Soil pollution is again another cause of land pollution that affects not only the land, but also a lot of other things such as forest cover of a region, productivity of land in terms of agriculture, grazing etc.
Soil pollution is also caused by wrong agricultural practices, such as overuse of chemical fertilizers and pesticides. Land Pollution: Essay on Land Pollution ( Words) Article are considered to be the indestructible poisons and then accumulation in plants and water may be highly dangerous because these inhibit the production of atmospheric oxygen reduce the rate of photosynthesis.
Now let us discuss the effect of land pollutants from different.
