Environmental pollution

  1. 1. ENVIRONMENT POLLUTION Submitted By: Surbhi Jha C.S.E(6th sem)
  2. 2. OUTLINES OF PRESENTATION -Introduction to Environmental Pollution -Types of environmental pollution -Seven categories of pollution -Health effects of pollution -Acts taken by government in India -Tips to save earth -References
  3. 3. INTRODUCTION TO ENVIRONMENT POLLUTION  Environmental pollution is the introduction of harmful pollutants into a certain environment that make an environment unhealthy to live in. The widespread pollutants are usually chemicals, garbage, and wastewater. Environmental pollution is happening in multifold parts of Earth usually in the form of air and water pollution.
  4. 4. AIR POLLUTION It is defined as the excessive concentration of foreign material in the atmosphere , which affects the health of individuals and also causes damage to the property . Some examples of air pollution include: -Exhaust fumes from vehicles. -The burning of fossil fuels, such as coal, oil or gas. -Harmful gases from things such as paint, plastic production . -Radiation spills or nuclear accidents. Effects: Air pollution is linked to asthma, allergies and other respiratory illnesses. Prevention: -Use natural Gases, like CNG autos. -Do not Burst Crackers. -Use less Amount of Fuel for Vehicles.
  6. 6. LAND POLLUTION Land pollution is the degradation of the Earth's surface caused by a misuse of resources and improper disposal of waste. Some examples of land pollution include:  Litter found on the side of the road.  Illegal dumping in natural habitats.  Oil spills that happen inland  The use of pesticides and other farming chemicals.  Damage and debris caused from unsustainable mining and logging practices.  Radiation spills or nuclear accidents. Effects: Land pollution is responsible for damage done to natural habitat of animals, deforestation and damage done to natural resources. Prevention:  More and more land should be brought under farming.  Trees should be planted everywhere.  Waste matter should be disposed immediately.  Avoid drilling the Land for more underground water.  Avoid using more fertilizers and Pesticides.
  7. 7. LIGHT POLLUTION  Light pollution is the brightening of the night sky inhibiting the visibility of stars and planets by the use of improper lighting of communities. Some examples of what causes light pollution:  Street lamps that shine light in all directions, instead of with a hood to point light downward toward the street.  Unnecessary lights, especially around the home. Effects:  Light pollution uses more energy (by shining more light up instead of down), may affect human health and our sleep cycles and most importantly, corrupts our kids telescopes and their curiosity. Prevention: Light only what needs lighting.  Use only as much light as is required. Don’t always install the highest available wattage. If you’re not performing surgery on your patient, there’s no need for operating room illumination levels.  Use only full cutoff light fixtures. Full cutoff fixtures shine light down onto the ground and prevent light from shining thoughtlessly across property lines or wastefully up into the night sky. Starry Night Lights was created to provide home and business owners with the widest selection of full cutoff light fixtures.  Shield your existing fixture. If you’re not quite ready to install new, full cutoff fixtures, light shades are available for many fixtures that will convert them into night sky friendly fixtures for a minimal cost.
  8. 8. Noise pollution Noise pollution is any loud sounds that are either harmful or annoying to humans and animals. Some examples of noise pollution: •Airplanes, helicopters and motor vehicles. •Construction or demolition noise. •Human activities such as sporting events or concerts. Effects: Noise pollution is disruptive to humans' stress levels, may be harmful to unborn babies, and drives animals away, causing nervousness and decreasing their ability to hear prey or predators. Prevention: -Pleasant Home. -Sound affects our ears so loud noise should be avoided.
  9. 9. THERMAL POLLUTION  Thermal pollution is the increase of temperature caused by human activity.  Warmer lake water from nearby manufacturing (using cool water to cool the plant and then pump it back into the lake). Effects: These kinds of environmental pollution can cause aquatic life to suffer or die due to the increased temperature, can cause discomfort to communities dealing with higher temperatures and can even affect plant-life in and around the area. Prevention: -Limit the amount of heated water discharged into the same body of water.
  10. 10. VISUAL POLLUTION Visual pollution is what you would call anything unattractive or visualisation damaging to the nearby landscape. This tends to be a highly subjective topic, as we all find different things attractive and unattractive. Some examples of visual pollution: •Skyscrapers might block the view of a mountain. •Graffiti or carving on trees, rocks or other natural landscapes. •Billboards, litter, abandoned homes and junkyards could also be considered among three kinds of environmental pollution. Effects: Mostly visual kinds of environmental pollution are annoying, although some may say they are also depressing (such as when they can't see a view through a billboard). Prevention:Don’t put many posters or paintings in one place all together.
  11. 11. WATER POLLUTION Water pollution is the contamination of any body of water (lakes, groundwater, oceans, etc). Some examples of water pollution:  Raw sewage running into lake or streams.  Industrial waste spills contaminating groundwater.  Radiation spills or nuclear accidents.  Illegal dumping of substances, or items in bodies of water.  Biological contamination, such as bacteria growth. Effects: These kinds of environmental pollution are linked to health issues in humans, animals and plant-life. Prevention: Rivers should not be used for washing clothes or bathing animals.  Harvesting of Rainwater to meet water requirements.  Dams & embankments must be created.  The rivers must not be contaminated.  In sacred river like Ganga the dead bodies shouldn’t be thrown.
  12. 12. RADIO ACTIVE POLLUTION Despite the Advantage of nuclear as a clean energy, the big concern is the resulted from nuclear reaction, which is a form of pollution called Radio activity. Causes:  Nuclear power plants.  Nuclear Weapon(example: Missiles).  Disposal of Nuclear Waste.  Uranium Mining. Effects:  The Diseases include blood in cough.  Ulcer.  Swelling of bone joints.  Cancer.  Lung Cancer.  Skin Cancer.  Bone Cancer.  Eye Problems. Prevention: Treatment for Nuclear Waste.  Avoid Constructing Nuclear Power Plants.  Avoid Using Nuclear Weapon.  Avoid mining for uranium to a minimal.
