Pollution started from prehistoric timeswhen man created the first fires.
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.The concept of economic growth is one which has attracted the interest and focus of researchers worldwide.
