2.  Air pollution is a mixture of solid particles and gases in the air. Car emissions, chemicals from factories, dust, pollen and mold spores may be suspended as particles. Ozone, a gas is major part of air pollution in cities. Inhaling them can increase the chance you’ll have health problems.

3. AIR POLLUTANTSSOURCES  Sulfur oxides (SO x )  Nitrogen dioxides (NO 2 )  Carbon monoxide (CO)  Hydrocarbons (HC)  Particulate  ozone  Combustion of fuels  Indrustrial process  Transportation  Combustion of fuels  Transportation  Agricultural burning  Transportation  Indrustrial process  Combustion of fuels  Derived from reactions with sunlight, NO 2, & O 2

4.  Air pollution affect visual resources by discoloring the atmosphere and by reducing atmosphere clarity so that visual contrast of distants objects is decreased.  The effect of air pollution on vegetation include damage to leaf tissue, fruit, or reduction in growth rate.  In some part of the world, air pollution is thought to be a significant factor in the human death rate.  Air pollution can affect human health in several ways. Some effect are eye irritation and irritation of respiratory systems.  The effect of air pollution on vertebrate animals include impairment of the respiratory system, and can damage to eyes.  Air pollution can degrade soil and water resources when pollutants from the air are deposited.

5.  Input control involves preventing problem before it occurs, or at least limiting effects the process will produce. Five major input control methods exist. People may try to restrict population growth, use less energy, improve energy efficiency, reduce waste, and move to non-polluting renewable forms of energy production. Also, automobile-produced pollution can be decreased with highly beneficial results.

6.  Output control, The opposite method, seeks to fix the problems caused by air pollution. This usually means cleaning up an area that has been damaged by pollution

7.  Water pollution refers to degradation of water quality. In defining pollution, we generally look at the intended use of the water, how far it departs from the norm, its effects on public health, or its ecological impacts.

8. POLLUTANT CATEGORYTHE SOURCES  Nutrients  Organic chemicals  Sediment  Acids  Oil Pollution  Dead organic matter  Phosporus and nitrogen from agricultural and waste water from sewage treatment.  Agricultural use pesticides and herbicides  Natural erosion  Industrial processes  The accidant of oil tanker so the oil floads to the sea  Agricultural waste  Sewage

9.  Take oil spills, for example. They can happen if tankers have accident at sea. The oil can wash up on nearby beaches, devastate the ecosystem, and severely affect tourism.  Sewage discharged into coastal waters can wash up on beaches and cause a health hazard. People who bathe or surf in the water can fall ill if they swallow polluted watersurf

10.  Education Making people aware of the problem is the first step to solving it. People who've grown tired of walking the world's polluted beaches often together to organize community beach-cleaning sessions. Greater public awareness can make a positive difference.

11.  Laws Environmental laws can make it tougher for people to pollute, but to be really effective they have to operate across national and international borders.

12.  Economics Most environmental experts agree that the best way to tackle pollution is through something called the polluter pays principle. This means that whoever causes pollution should have to pay to clean it up. Polluter pays can operate in all kinds of ways.

13.  Air pollution that be found in the indoors, causing indoor air pollution. Pollutants can be trapped inside buildings, that lasts for a long time.

14. POLLUTANTSSOURCE  Carbon dioxide  Carbon monoxide  Sulfur dioxide  Ozone  Asbestos  Biological aerosol  Motor vehicle, smoking  Motor vehicle, wood stoves, smoking  Coal and oil combustion  photocopying machine, electrostatic air cleaner  Cement product & vinyl floor  Air conditioning system

15.  Indoor air pollution has different effect on different people, and some groups of people are particularly susceptible to air pollution problems. Often the symptoms reported by people working in a building vary, and the symptoms may result from factors other than air pollution.

16.  The symptoms are allergies, asthma, bleeding lungs, breathing difficulties, cancer, central nervous system effects, coughing, flu symptoms, headaches, eye problems and etc.

17.  Ventilation : general ventilation system  Air cleaning : particles filtering, gas removal  Source modification : change in combustion design (maximize efficiency of a gas stove, material subtitution)  Source removal:restriction on source (establishment of smoking area)  Education : public information on health, nuisance effects and etc)
