Introduction: What is Pollution?

Pollution is the introduction of contaminants( 污染物 ) into the natural environment that cause adverse( 不利的 ) change.Pollution can take the form of chemical substances or energy, such as noise, heat or light. Pollutants, the components of pollution, can be either foreign substances or naturally occurring contaminants.

At 11 March 2014 Cikgu Elizah gave us a work,we have to do a folio which is about the source of pollution.Teacher has taught us how to do,she gave us see the example of how our senior done it before.After that we started to search the information of our topic,When we have collected the information we started to do our folio as soon as we can.

Objective

To understand what pollution is and the cause of pollutionLearning outcome:We are able to:-I. Explain what is pollutionII learn the source of environmental pollution

Discussing 12 March 2014 discuss the work

Pocessing and Finishing 12 March 2014rearrange and put together to form folio and ready to

pass up

Source of Pollution

Land Pollution

Water Pollution

Air Pollution

Sound Pollution

Land Pollutionwhat is land pollution? Land pollution is the destruction of

the earth’s land surfaces, often directly or indirectly as a result of man’s activities and their misuse of land resources.

Solid Waste These include all the various kinds

of rubbish humans make at home, school, hospitals, market and work places. Things like paper, plastic containers, bottles, cans, food and even used cars and broken electronic goods, broken furniture and hospital waste are all examples of solid waste.

Deforestation

Human cut down millions of tree for wood, construction, farming and mining purposes, and never planted new trees back. This is a type of land pollution

Water Pollution

What is water pollution? Water pollution occurs when

pollutants are discharged directly or indirectly into water without enough treatment to get rid of harmful compounds. Pollutants get into water mainly by human causes or factors.

Oil Spillage

Oil spills usually have only a localized affect on wildlife but can spread for miles. The oil can cause the death of many fish and stick to the feathers of seabirds causing them to lose the ability to fly

Ocean and marine dumping

In some countries, there are deposited into the sea. All these waste types take time to decompose.When these end up in the sea, they harm sea animals and cause a lot of deaths.

Sewage Disposal

Sewage is a mixture of water and humans waste and animals.Improper disposal of sewage can cause water pollution.Dirty sewage water encourages the growth of bacteria.These bacteria will used up all the oxygen inside the ocean causing unsuitable for aquatic life.

Air Pollution

What is air pollution? Air pollution occurs when gases, dust

particles, smoke or odour are introduced into the atmosphere in a way that makes it harmful to humans, animals and plant.

Burning Fossil Fuels

Cars and heavy duty trucks, trains, shipping and airplanes all burn lots of fossil fuels to work. Emissions from automobile engines contain both primary and secondary pollutants. This is a major cause of pollution, and one that is very difficult to manage.

Picture of Burning Fossil Fuels

Carbon dioxide(CO2 ) from exhausts and energy production Methane(CH4) from cattle breeding Sulfur oxides(SOX) from exhausts and industry CFCs from refrigerants and propellants Nitrogen oxides(NOX) from exhausts and industry Ozone(O3) from air with high oxygen level, catalysed by nitrogen oxides Soot and particulate(PM) from exhausts and industry

Sound Pollution

What is sound pollution Noise pollution is the disturbing or excessive

noise that may harm the activity or balance of human or animal life. The source of most outdoor noise worldwide is mainly caused by machines and transportation systems, motor vehicles, aircraft, and trains.Outdoor noise is summarized by the word environmental noise. Poor urban planning may give rise to noise pollution, since side-by-side industrial and residential buildings can result in noise pollution in the residential areas.

Example of Sound Pollution

Summary

Type of pollutant Source of Pollutant

Carbon Monoxide Exhaust gas

Lead Exhaust gas

Nitrogen Dioxide Burning of fuel, oil and coal

Sulphur Dioxide Burning of fossil fuel

Dust,smoke and smog(烟雾 ) Burning of fossil fuel

Radioactive substance Nuclear power stations

Chemical substance Chemical factories,pesticides(农药 )
