  1. Air Pollution Pollutants and its Sources

  2. Members: III-Molave • Frinze Mell Barba • Lester Librado • Jalal Udine Omping • Sittie Aisah Isah • Nasima Palaindo • Normindah Sanguila

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

  4. The 6 Air Pollutants • They are particle pollution (often referred to as particulate matter) , ground-level ozone, carbon monoxide, sulfur oxides, nitrogen oxides, and lead. These pollutants can harm your health and the environment, and cause property damage. Of the six pollutants, particle pollution and ground-level ozone are the most widespread health threats.

  6. Sources and effects of Air pollution

  7. Effects of to us • Lung inflammation can lead to the release of chemicals from macrophages that cause changes in the clotting mechanisms of the blood. • Air Pollution may cause Asthma. • A neural reflex may be initiated by the irritant effects of air pollutants in the lung leading to changes in heart rhythm and rate. • Malaria has spread to higher altitudes in places like the Colombian Andes, 7,000 feet above sea level. • Deaths from global warming will double in just 25 years -- to 300,000 people a year

  8. Effect of Air pollution to the Environment • The flow of ice from glaciers in Greenland has more than doubled over the past decade. • At least 279 species of plants and animals are already responding to global warming, moving closer to the poles. • Global sea levels could rise by more than 20 feet with the loss of shelf ice in Greenland and Antarctica, devastating coastal areas worldwide. • Heat waves will be more frequent and more intense. • Droughts and wildfires will occur more often.

  9. Ways of how to lessen the air pollution in the Environment • 1)Use the new machine that recycles plastics into a useful fertilizers. • 2)Stop using fueled cars. Use the new machine, the Electric cars. • 3)Lessen of using cigarettes in smoking • 4)Stop Burning plastics to AVOID the cause of Ozone holes.

  10. Ozone Ozone can penetrate 1 micron into the acini cells without reacting with the epithelial lining fluid. Therefore it penetrates the epithelium of the lung in the lower airwys where the epithelial lining fluid is thinner than 1 micron. Particulate Matter The particles are of major concern as they are small enough to penetrate deep into the lungs where they can cause inflammation and the worsening condition of those with pre-existing heart and lung conditions The gaseous characteristics/properties of air pollutants which  causes the rapid harm to human health and environment

  11. Oxides of Nitrogen Nitric and nitrous acids are formed on the moist surfaces of the airways. Lipid peroxidation takes place on the cell membranes and many structural and functional molecules are damaged by free radicals. Particularly strong free radicals are formed when Nitrogen dioxide oxidises lecithin in cell membranes or interacts with haeme. Sulphur Dioxide It reacts on the surface of a variety of airborne solid particles, is soluble in water and can be oxidised within airborne water droplets. On contact with water vapour or water bound to particulate pollutants, sulphurous acid is formed which rapidly dissociates to give acidic solutions.

  12. Carbon Monoxide Carbon monoxide is a toxic gas, which is emitted into the atmosphere as a result of combustion processes. It is also formed by the oxidation of hydrocarbons and other organic compounds Lead Particulate lead in the air results from activities such as fossil fuel combustion, metal processing industries and waste incineratrion. It's single largest industrial use worldwide is in the manufacture of batteries.

  13. Breathing Some Fresh Air?

  14. This is WHAT will happen if we will not save EARTH!
