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 sickit causes breathing
  problems and promotes cancerand 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.

CONTINUATION

• Pollution is changing Earths 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

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
Health Effects

• 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 dont
  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 dont top off your tank.

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.
