Air+Pollution

= = What is Air pollution?
 * Air Pollution**
 * Lester Wong**
 * Air pollution** is the change in the natural atmosphere by the addition of other gases particulates and volatile organic compounds.

The gaseous air pollutants are carbon monoxide, nitrogen oxides, sulfur oxides, CFC

Air pollution Sources
 * Anthropogenic sources**
 * Combustion of fossil fuels
 * Fumes from paint, hairy spray , aerosol sprays.
 * Waste deposition in landfills which generate methane
 * Military weapons such as nuclear weapons toxic gases and rockets.


 * Natural Sources**
 * Dust from natural sources usually places with no trees or greenery
 * Smoke and carbon monoxide from wild forest fires
 * Volcanic activity which releases sulfur chlorine and ash particulates into the atmosphere.
 * Methane from animals formed by the digestion of food.(waste gas)

When these oxides mix together with the water in the atmosphere it will become acid. Thus whenever it rains it will be acid rain, it will cause damage to us in all ways.
 * Sulfur and nitrogen oxides**
 * found in the fossil fuels we use to produce energy when we burn them we release these gases into the air.


 * Carbon Monoxide**
 * colorless odorless and non irritating poisonous gas. It is produced when there is incomplete combustion of fossil fuels.
 * It will combine with the hemoglobin of your blood and produce carboxyhemoglobin which makes the red blood cell ineffective for delivering oxygen to other parts of the body.


 * Particulates**
 * Made up of metal, soot, soil or dust particles.
 * formed by forest fires, combustion of internal combustion engines.
 * Large particles can be trapped in the nostrils
 * smaller particles cannot be trapped and when they enter your body they will cause infection


 * Volatile organic compounds (VOCs)**
 * Found in an internal combustion engine
 * markers, varnish , cleaning supplies , building materials.
 * Causes people to feel sick and have building syndrome.


 * Ways to reduce air pollution**
 * **Grow more trees around the polluted area.**
 * Use public transport when possible instead of using private transport.
 * Save energy whenever possible
 * Change your catalytic converters in your motor vehicle once in a while so it works efficiently

Schematic drawing, causes and effects of air pollution: (1) greenhouse effect, (2) particulate contamination, (3) increased UV radiation, (4) acid rain, (5) increased ozone concentration, (6) increased levels of nitrogen oxides
