- 3. Pollution Pollution is theintroduction of contaminants into the natural environment that cause adverse change. Pollution can take the form of chemical substances or energy, such as noise, heat or light. pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants. Pollution is often classed as point source or nonpoint source pollution
- 4. Types Of pollution •Air Pollution • Water Pollution • Soil Pollution • Noise Pollution • Radioactive Pollution • Thermal Pollution • Personal Pollution
- 5. Introduction Of Soil Soilcan be defined as the uppermost crust of earth mixed with organic material and in which animals and microorganisms live, and plants grow.
- 7. Soil pollution • Soilpollution is defined or can be described as the contamination of soil of a particular region. • Soil pollution is caused by addition of chemicals, which reduces its productive capacity. • In rural areas more fertilizers & pesticides are used in agricultural operations & the residual chemicals remain in the top layers of soil.
- 8. Sources of Soilpollution • Acid Rains • Excess application of pesticides fertilizer • Urban solid wastes • Disposal of industrial wastes and sludge over land
- 9. Acid rain Acid Rainis caused by air pollution. The acidic water falls on the soil and pollutes it by making the soil acidic.
- 10. Fertilizers The use ofexcess fertilizers to increase the crop yields makes the soil either acidic or alkaline and pollutes it. Ex: ammonium sulphate , sodium nitrate
- 11. Fertilizers • Excess useof Na, Mg, Ca, K, Zn in the form of fertilizers & pesticides inhibit plant growth & reduce crop yield.
- 12. Urban wastes • Thesewastes include a wet and fermentable fraction, made of food residuals from houses, restaurants and food industries, paper.
- 13. POLLUTANTS ORGANIC WASTE COMPOUNDSEXCESS USE OF FERTILIZERS
- 14. POLLUTANTS • Organic waste Organicwaste enter the soil pores & decompose pathological bacteria spread infection. • Compounds waste Compounds containing arsenic, mercury, chromium, nickel, lead, Zinc, & iron are toxic to the life. Fluorides also affect the plant development.

- 17. Pollutants • Excess useof fertilizers Excess use of Na, Mg, Ca, K, Zn, in the form of fertilizers & pesticides inhabit plant growth & reduce crop yield.

- 19. Humans Effects CAUSES CANCERSINCLUDING LEUKEMIA. MERCURY CAN INCREASE THE RISK OF KIDNEY DAMAGE. ALSO CAUSE HEADACHES, EYE IRRITATION & SKIN RASH.

- 21. Animals Effects • Smalllife forms may consume harmful chemicals which may then be passed up the food chain to large animals.
- 22. Agricultural Effects • Decreasesoil fertility. • Reduced crop yield. • Larger loss of soil & nutrients. • Reduced nitrogen fixation.
- 23. Urban Effects • Publichealth problems. • Pollution of drinking water sources. • Foul smell & release of gases. • Waste management problems.
- 24. Control of soil pollution •Ban on use of plastic bags which are major cause of pollution in cities. • Recycling of plastic wastes to manufacture many ‘remake’ items. • Ban on deforestation. • Encouraging forest replantation programmes. • Use carefully the fertilizers & pesticides preferable in optimal dose.
