  2. SOILPOLLUTION 1

  3. SOIL POLLUTION • Soil pollution is the introduction of substances, biological organisms, or energy into the soil, resulting in a change of the soil quality, which is likely to affect the normal use of the soil or endangering public health and the living environment. • Soil contamination is caused by the presence of XENOBIOTIC chemicals or other alteration in the natural soil environment. 2

  4. SOURCES OF SOIL POLLUTION • Human and Animal excreta • Organic Insecticides & Pesticides • Chemical Pollutants • Radioactive Substances • Urban Wastes • Industrial Pollutants • Absorption of Toxic Metals 3

  5. Plastic packaging and plastic rings, Plastic bags for more plastic things, Plastic bottles for the water you drink, But plastic causes death so stop and think! 4

  6. EFFECTS • Water mixed with human excretes, sewage and sludge kills the microorganism and reduces the fertility of soil. • Garbage, sludge and dead animals create bad odor which causes chronic diseases. • Urban solid wastes such as rubbish, broken articles etc obstruct the public passage. • Pesticides seep gradually through the soil and contaminate the underground drinking water storage. • Hazardous substances can indirectly affect the food chain and thus the entire ecosystem. 5

  7. Control of Soil Pollution • Prevention of soil erosion and degradation by forestation. • By using fewer pesticides and bio fertilizers. • Zooming farming. • Bioremediation: treatment process that uses microorganisms to break down hazardous substances. 6

  9. NOISE POLLUTION NOISE POLLUTION 8

  10. Noise Pollution • Noise pollution can defined as unwanted or offensive sound that unreasonably intrude into our daily activities. • Noise pollution is excessive, displeasing human, animal, or machine-created environmental noise that disrupts the activity or balance of human or animal life. 9

  11. Sources Of Pollution • Industrial sources. (grinding, cutting, pressing, welding etc.) • Non-industrial sources. (traffic, loudspeaker, Construction etc.) 10

  12. Effects Of Noise Pollution Effects of noise pollution Auditory Fatigue Auditory Effects Non-Auditory Effects Annoyance Physical disorder Auditory fatigue Deafness Loss of Working efficiency 11 Interference In speech Communication

  13. Noise Pollution Level & Its Harmful Effects 12

  14. Control of Noise Pollution • Control at the receiver’s end • Suppression of noise at source • Creating silence zone • Sound insulation • Planting of trees • Legislative measures 13

  15. Look Outside, see the treesWatch the flowers in the breezeThings won't be like this in a year or twoIf polluting is all we do so wake up people Show the world what you can do. 14
