Causes Of Water Pollution
Air Pollution Sources
1. INTRODUCTION
Naturally from the earth to receive loads of water pollution from natural phenomena as volcanic eruptions Such, forest fires due to lightning and so forth. However, the Earth has a 'natural approach' to address the Contamination is natural. When people began to run daily activities or industrial activities, widespread environmental Contamination and the Earth cans no longer 'bear' the burden of pollution.
2. INDUSTRIAL & DEVELOPMENT ACTIVITIES

The development of Malaysia's economy Depends on manufacturing industries, especially electronics, chemicals and rubber. However, Increasing the rate of production has resulted in the Addition of pollution emissions of organic and inorganic gases, chemicals and dust. A wide range of industries producing different contaminants. For example, the chemical releases of pollutants That are based on different compounds of nitrogen and sulfur, while the oil refinery emits smoke containing sulfur dioxide and hydrocarbons. Metals industry is Responsible for polluting the air with sulfur dioxide and toxic dust. Some pollutants, particularly carbon dioxide is a greenhouse gas That cans cause extremely harmful climate change around the world. In Addition to the release of toxic substances into the water, the development of the premises or an industrial zone without careful planning and control will of cause noise pollution and vibration. Activities at construction sites and sounds of exhaust fan in the Factories Are Among the examples of activities That Produce high noise levels.
3. MOTOR VEHICLE
Modern society is dependent on transport vehicles Heavily Such as cars, trucks and trains. Every movement of motor vehicles using a lot of energy and Almost all of produced by burning fossil fuels, the which Produce smoke and noise of an adverse effect on the local situation. Depends on ambient water quality Used type of transport, type of energy source, the engine technology and the amount of energy required. In the transportation sector, motor vehicles are major contributors to air pollution. Use of public transport will of reduce the impact of pollution on the environment. In 2004, 14 million registered vehicles in Malaysia, this figure is two-fold compared with a decade ago. These numbers will of continue to increase is from year to year, with rising incomes, rural-urban transfers and lack of efficient public transport facilities.
4. POWER GENERATION
Almost all the electricity generated by burning fossil fuels Such as natural gas, oil and coal. Power plants of this type have kecekepan Between levels 35 and 40 percent in the rest turns into heat energy. At present, Malaysia to generate 86 percent of its electrical energy needs through conventional power plants while the remaining 14 percent is produced by hydro power stations.
5. DAILY ACTIVITIES
Households Contribute to pollution through the use of energy to machinery and electrical appliances Such as Refrigerators. Refrigerators and water conditioners not only uses more energy, but these tools pollute the water are Pls Also the liquid coolant Used in releasing Klorofluorokarban (CFCs) into the water then thinning the ozone layer. Home appliances Such as aerosol sprays containing CFCs Also are sources of water pollution.
6. Open Burning
Burning of old trees in plantations for the purpose of replanting a lot of soot particles. These soot particles cans be blown long distances by the wind and this causes the haze That Often surrounds Malaysia's water space. The fire of the burning is not only producing smoke That pollute, but Also it destroys all the fauna and flora in the vicinity.
