  1. 1. POLLUTION Every day , harmful materials are released into the environment as a result of human activities. This is pollution.
  2. 2. <ul><li>There are 6 (six) types of pollution namely air, water, noise, land, radioactive, and thermal. </li></ul><ul><li>Water Pollution </li></ul><ul><li>Land Pollution </li></ul><ul><li>Noise Pollution </li></ul><ul><li>Radioactive Pollution </li></ul><ul><li>Thermal Pollution </li></ul><ul><li>Air Pollution </li></ul>
  3. 3. Air Pollution <ul><li>Air pollution is indication of disturbances to the composition of compounds in the atmosphere, as it may be summarized as shown: </li></ul><ul><li>excess emission of gases/vapors into atmosphere </li></ul><ul><li>saturation of chemical compounds/particulates </li></ul><ul><li>rate of dissipation < (smaller than) rate of absorption through various cycles (i.e. carbon and nitrogen cycle) </li></ul><ul><li>emergence of new chemical reactions of reactive and non-biodegradable compounds </li></ul>
  4. 4. Sources of air pollution <ul><li>motor vehicle exhaust </li></ul><ul><li>heat and power generation facilities </li></ul><ul><li>industrial processes </li></ul><ul><li>auto manufacturing </li></ul><ul><li>fertilizers plants </li></ul><ul><li>building demolition </li></ul><ul><li>volcanic eruption </li></ul><ul><li>fuel production </li></ul><ul><li>roadway construction </li></ul>
  5. 5. WATER POLLUTIONS <ul><li>Water pollution is contamination of water by foreign matter that deteriorates the quality of the water. Water pollution covers pollutions in liquid forms like ocean pollution and river pollution  As the term applies, liquid pollution occurs in the oceans, lakes, streams, rivers, underground water and bays, in short liquid-containing areas. It involves the release of toxic substances, pathogenic germs, substances that require much oxygen to decompose, easy-soluble substances, radioactivity, etc. that become deposited upon the bottom and their accumulations will interfere with the condition of aquatic ecosystems. </li></ul>
  6. 6. Sources <ul><li>petroleum products </li></ul><ul><li>synthetic agricultural chemicals </li></ul><ul><li>heavy metals </li></ul><ul><li>hazardous wastes </li></ul><ul><li>excess organic matter </li></ul><ul><li>sediment </li></ul><ul><li>infectious organisms </li></ul><ul><li>air pollution </li></ul><ul><li>thermal pollution </li></ul><ul><li>soil pollution  </li></ul>
  7. 7. Land Pollution <ul><li>Revered  to as soil pollution, land pollution involves the following mechanism: </li></ul><ul><li>Deposition of solid waste </li></ul><ul><li>Accumulation of non-biodegradable materials </li></ul><ul><li>Toxification of chemicals into poisons </li></ul><ul><li>Alteration of soil chemical composition (imbalance of chemical equilibrium to soil medium) </li></ul>
  8. 8. Sources <ul><li>agriculture </li></ul><ul><li>mining and quarrying </li></ul><ul><li>sewage sludge </li></ul><ul><li>dredged spoils </li></ul><ul><li>household  </li></ul><ul><li>demolitions and constructions </li></ul><ul><li>industrial </li></ul>
  9. 9. Noise Pollution <ul><li>This particular pollution is ever increasing with due to the rise in the utilization of heavy duty machineries of industrial facilities and vehicles, synonymous to the increase in the standard of living in most countries. We make sounds practically every seconds of our day, but to the extend it has reached an unfavorable high intensity which had cause many disturbances and irritation to others emotionally that has adverse effects on our daily activities. </li></ul><ul><li>Noise levels can be measured by decibel method: </li></ul><ul><li>Decibel - one tenth of a bel where one bel represents a difference in level between two intensities I1, I0 where one is ten times greater than the other. </li></ul>
  10. 10. Noise measurement system <ul><li>community noise equivalent level </li></ul><ul><li>composite noise rating  </li></ul><ul><li>equivalent energy level </li></ul><ul><li>noise and number index </li></ul><ul><li>noise exposure forecast  </li></ul><ul><li>noise level </li></ul><ul><li>noise pollution levelnoise rating </li></ul><ul><li>perceived noise level </li></ul><ul><li>traffic noise index </li></ul><ul><li>sound level </li></ul><ul><li>sound level meter </li></ul><ul><li>sound pressure level </li></ul>
