STOP POLLUTION!

ION

Do you know that Singaporeans throw away 2.8 million tons of rubbish in 1999?
If this amount of rubbish is stacked up to a man height of 1.7 meters it would occupy up to 350 football fields!
Every day a Singaporean discards 1.1 kilograms of rubbish.

Incineration is one of the methods in dealing with solid waste, let us discuss more about incineration.

In Singapore, we have four incineration plants. They are in Ulu Pandan, Tuas, Senoko and Tuas South. These incineration plants generate energy from the heat that is produced in the process of burning the rubbish.

- Tuas South Incineration Plant.

Incineration is a good way of disposing rubbish as it can recover scrap metal for recycling.
One incineration plant has enough energy to power two hosing estates and recover 28,800 tonnes of scrap metal for recycling.
Although, burning reduces the waste by 90%, but there is also another 10% of ashes that need to be disposed in landfills. In addition, a lot of energy is needed to burn the waste. Hence, the better way to reduce land pollution is still through the 3Rs, reduce, reuse and recycle.

Noise Pollution can affect our hearing and bring us hearing problems too.

Other than those measures that i had mentioned in the earlier post that can reduce noise pollution, there are some other ways too. For example,

ear protectors and noise shields must be provided to the employees in working environments to prevent their hearing being damaged.

install noise barriers where there are noisy equipments

In Singapore, many shops in the malls or neighbourhood blast out their music loudly, either competing for business or attract/entertain customers. However, the shop owners didn't realise that this can also be a form of noise pollution when the music volume is too loud and customers might have an unpleasant shopping experience.

Some kopitiams can also be found in the neighbourhood and even during mid-night, there can still be some noise. As these kopitiams are open-air area, any noise made can be heard by residents clearly at night. These noises can certainly affect them from resting. Gangsters and uncles might also sprout vulgarities and screaming/shouting when they are watching football match together from the television in the kopitiams. All these can greatly affect all the residents!

So, the government should also do something or enforce some laws to stop people from making too much noises during late at night because they can certainly affect residents!

Noise Pollution can affect our hearing.

This picture depicts how the great volume of noise affect us and stress us.

Noise Pollution occurs when unwanted sounds intrude our daily life. For example,

constant whirring of computers and air conditioners

sound of busy traffic

running car engine

sounds make by noisy instruments

screaming and shouting of human

When all these noises mounds up, they will turn in noise polltuion and cause negative impacts on the public. For example,

affecting human health

causing stress on people

hearing loss on people

affecting the performance made by employees and students

Many people tend to ignore the consequences of noise pollution as they do not see it as a threat to them. However, noise pollution can still affect our daily lives greatly and we should do something to avoid it.

Singapore is an island, a city state. It has a total land area of 650 square kilometres and a population of 4.1 million. With limited land and a high population density, it has to meet the challenge of building a comprehensive, efficient and yet environmentally acceptable land transport system.

Things had been done to their utmost to minimize the adverse impacts of an ever expanding transport network.

In highly urbanized Singapore, noise pollution from road traffic and MRT/LRT trains receives much attention. With further urbanization and the widening of expressways, noise levels have been gradually rising in some areas, especially those along existing expressways.
New buildings are required to fronting expressways, major arterial roads and MRT tracks to be set back from these thoroughfares so as to minimize the impact on residents.

In addition, Singapore have set noise emission standards for vehicles, and are using low-noise porous asphalt to pave our expressways. We have adopted noise-damped rail tracks and wheels for MRT trains. The LRT trains have rubber wheels, and we make them run on concrete tracks to keep the noise level down.

Noise is a disturbance to the human environment that is escalating at such a high rate that it will become a major threat to the quality of human lives. In the past thirty years, noise in all areas, especially in urban areas, have been increasing rapidly. There are numerous effects on the human environment due to the increase in noise pollution.

Here are some facts on Noise

Noise or sound is measured in decibels, dB. The basic instrument used for the measuring of noise is the sound level meter.

This instrument is designed to respond in approximately the same way as the human ear and gives objective assessment of sound pressure level.
Typical sound levels measured in the surrounding are as follows:
library - 35 dB
office - 60- 65
normal traffic noise 70 - 80 dB
Airport (plane take off) - 120 dB

Subjected to 45 decibels of noise, the average person cannot sleep. At 120 decibels the ear registers pain, but hearing damage begins at a much lower level, about 85 decibels. The duration of the exposure is also important.

When there is large exposure to noise, including excessively amplified music, it results in hearing loss, lack of sleep, irritability, heartburn, indigestion, ulcers, high blood pressure, and possibly heart disease. In addition, noise-induced stress creates severe tension in daily living and contributes to mental illness.

How serious can Noise Pollution be? Noise Pollution is becoming an unpleasant fact of life and it affects our quality of life. Noise causes discomfort and has a negative impact on our health. Scientists have also found out that long-term exposure to Noise Pollution can result in negative consequences. Firstly, it can damage our hearing or cause a loss of hearing. It may also increase our heart rate, anxiety and stress level which may lead to related health problems such as high blood pressure. Thirdly, Noise Pollution can result in poor performance in school or at work as our ability to concentrate is affected.

What has been the result of Noise Pollution? Let’s discuss on two of the causes that can be found in our country! Firstly, traffic can be a common cause of Noise Pollution, especially in cities. Cars on a busy road can produce about 60 to 90 decibels of noise. Besides cars, other types of vehicles can also cause Noise Pollution. An aircraft taking off produces noise of about 120 decibels while an MRT train entering a tunnel can produce noise of about 90 decibels.
Secondly, noise from drilling, piling, knocking and the use of heavy machinery during construction work all contribute to Noise Pollution. Other human activities, such as people talking loudly to one another, and events, such as concerts, are also some common causes of Noise Pollution.

Our group has faced alot of difficulties. As our subject teachers have given us different projects, we not only have to meet up and discuss for this project, but also for the other projects. Hence, we do not have much time for each project.

In addition, our group leader is a Student Councillor. She usually have SC meetings after school, thus we really do not have much time to have discussions after school.

During the June holidays, we have supplementary lessons, some of us have Advanced Elective Module(AEM), which last for about the whole day for the whole week, and some of our group members are going overseas .
From all these problems, we can see that time management is very important. We hope that we can manage our time properly and complete our projects in time.
