Pollution important

  1. 1. Pollution Types ,Causes ,control & effects
  2. 2. SLOGANS Plant a tree and get air for free. Feel free to plant a tree. A tree that stay, keep flood away. Take care of the trees, they will take care of you.
  3. 3. Pollution • Pollution is the introduction of contaminants into a natural environment that causes instability, disorder, harm or discomfort to the ecosystem i.e. physical systems or living organisms. 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. • The Blacksmith Institute issues an annual list of the world's worst polluted places. In the 2007 issues the ten top nominees are located in Azerbaijan, China, India, Peru, Russia, Ukraine and Zambia.
  4. 4. sources • Pollution comes from both natural and man made sources. • Though globally man made pollutants from combustion, construction, mining, agriculture and warfare are increasingly significant in the air pollution equation.

  13. 13. TYPES OF POLLUTION • WATER POLLUTION Water pollution is the introduction into fresh or ocean waters of chemical, physical, or biological material that degrades the quality of the water and affects the organisms living in it.
  14. 14. TYPES OF POLLUTION • THERMAL POLLUTION Thermal pollution is the discharge of waste heat via energy dissipation into cooling water and subsequently into nearby waterways. • LAND POLLUTION Land pollution is the degradation of the Earth's land surface through misuse of the soil by poor agricultural practices, mineral exploitation, industrial waste dumping, and indiscriminate disposal of urban wastes.
  15. 15. TYPES OF POLLUTION • Solid Waste • In the United States in 1988 municipal wastes alone--that is, the solid wastes sent by households, business, and municipalities to local landfills and other waste-disposal facilities-- equaled 163 million metric tons (1980 million U.S. tons), or 18 k (40lb) per person, according to figures released by the Environmental Protection Agency. Additional solid wastes accumulate from mining, industrial production, and agriculture.
  16. 16. TYPES OF POLLUTION • PESTICIDE POLLUTION Pesticides are organic and inorganic chemicals originally invented and first used effectively to better the human environment by controlling undesirable life forms such as bacteria, pests, and foraging insects. Their effectiveness, however, has caused considerable pollution. • RADIATION POLLUTION Radiation pollution is any form of ionizing or nonionizing radiation that results from human activities. The most well- known radiation results from the detonation of nuclear devices and the controlled release of energy by nuclear- power generating plants (see nuclear energy).
  17. 17. TYPES OF POLLUTION • NOISE POLLUTION Noise pollution has a relatively recent origin. It is a composite of sounds generated by human activities ranging from blasting stereo systems to the roar of supersonic transport jets. Although the frequency (pitch) of noise may be of major importance, most noise sources are measured in terms of intensity, or strength of the sound field. The standard
  18. 18. TYPES OF POLLUTION • AIR POLLUTION Air pollution is the accumulation in the atmosphere of substances that, in sufficient concentrations, endanger human health or produce other measured effects on living matter and other materials. • Degradation of air quality and natural atmospheric conditions constitute air pollution. • It is defined as the presence of one or more contaminants such as dust gas mist odor smoke smog etc. Causes harm to human plants animals or property.
