  2. INTRODUCTION • AIR POLLUTIONS

  3. AIR POLLUTION • Air pollution is a chemical , particulate matter , or biological agent that modifies the natural characteristics of the atmosphere . The atmosphere is a complex, dynamic natural

  4. Air Pollution, addition of harmful substances to the atmosphere resulting in damage to the environment, human health, and quality of life.

  5. Continuation: • One of many forms of pollution, air pollution occurs inside homes, schools, and offices; in cities; across continents; and even globally. Air pollution makes people sick—it causes breathing problems and promotes cancer—and it harms plants, animals, and the ecosystems in which they live. Some air pollutants return to Earth in the form of acid rain and snow, which corrode statues and buildings, damage crops and forests, and make lakes and streams unsuitable for fish and other plant and animal life.

  6. CONTINUATION: • Pollution is changing Earth’s atmosphere so that it lets in more harmful radiation from the. At the same time, our polluted atmosphere is becoming a better insulator, preventing heat from escaping back into space and leading to a rise in global average temperatures. Scientists predict that Sun the temperature increase, referred to as global warming, will affect world food supply, alter sea level, make weather more extreme, and increase the spread of tropical diseases

  7. SIX AIR POLLUTANTS • Particulate matter • Ozone • Oxide of Nitrogen • Sulphur Dioxide • Carbon monoxide • Lead and Heavy metals

  8. Health Effects • Respiratory effects • Symptoms: • Cough • wheezing • Phlegm • shortness of breathing • Chest tightness

  9. HealthEffects • Cardiovascular Effects • Symptoms: • Chest tightness • Chest pain (angina) • Palpitations • Shortness of breath • Unusual fatigue

  10. Environmental Effects • WHAT IS GLOBAL WARMING? Carbon dioxide and other gases warm the surface of the planet naturally by trapping solar heat in the atmosphere.

  11. What can one person do? • Kids stay away from the smoke coming out of the back of the school bus or any vehicle- you don’t want to breathe that. • Reduce exercise outdoors, when the air is smoky or smoggy. • Drive less ( walk, bike, carpool or take the bus more)! • When you do drive, combine car trips, keep your car turned up, and don’t top off your tank.

  12. Gaseous Characteristics of Air pollutants • The three properties of matter: • SOLID • LIQUID • GAS General properties of gases: • There is a lot of “ free” space in a gas. • Gases can be expanded infinitely. • Gases occupy containers uniformly and completely. • Gases diffused and mix rapidly.
