• Prevention is another key
to controlling air pollution. The regulatory agencies mentioned above play an essential role in reducing and preventing air pollution in the environment.
•So let's move up!!!!!
•
What can air pollution bring us? We can see, many many climate disaster occur everywhere every year and it become more and more powerful and destructive, we are under attacks by them and get so much hurts. In my opinion, these causes of disasters linked with air pollution. You know, air pollution may cause Greenhouse effects, and Greenhouse effects can lead El Nion, drought, flood and so on.
• Long-term health effects can include chronic respiratory disease, lung cancer, heart disease, and even damage to the brain, nerves, liver, or kidneys.
air pollution
•
With the developing of the economic and industry of china, our life quality has improved a lot, we want to live a good life, so the environment quality plays a important role in our life.
•
What is air pollution?Air is the ocean we breathe. Air supplies us with oxygen which is essential for our bodies to live. Air is 99.9% nitrogen, oxygen, water vapor and inert gases. Human activities can release substances into the air, some of which can cause problems for humans, plants, and animals.There are several main types of pollution and well-known effects of pollution which are commonly discussed. These include smog, acid rain, the greenhouse effect, and "holes" in the ozone layer. Each of these problems has serious implications for our health and well-being as well as for the whole environment.
•
So ,air pollution influence us a lot, now everybody must move to protect us from air pollution, we must learn a lot to get more good ways to reduce air pollution.
• As a chemical engineering student, I think the main pollution I Care more is black carbon pollution.
• Black carbon pollution is the release of tiny particles into the air from burning fuel for energy.
• Air pollution caused by such particulates has been a major problem since the beginning of the industrial revolution and the development of the internal combustion engine. Mankind has become so dependent on the burning of fossil fuels that the sum total of all combustion-related emissions now constitutes a serious and widespread problem, not only to human health, but also to the entire global environment.
•
One type of air pollution is the release of particles into the air from burning fuel for energy. Diesel smoke is a good example of this particulate matter. The particles are very small pieces of matter measuring about 2.5 microns or about .0001 inches. This type of pollution is sometimes referred to as "black carbon" pollution. The exhaust from burning fuels in automobiles, homes, and industries is a major source of pollution in the air. Some authorities believe that even the burning of wood and charcoal in fireplaces and barbe ques can release significant quantities of soot into can take more measures to protect our air. The air pollution in Beijing is so serious, we always under a gray sky, I hope I can see blue sky every day and have a good breath.
• Air pollution can affect our health in many ways with both short-term and long-term effects.
• Examples of shortterm effects include irritation to the eyes, nose and throat, and upper respiratory infections such as bronchitis and pneumonia. Other symptoms can include headaches, nausea, and allergic reactions.
•
The first step to solving air pollution is assessment. Researchers have investigated outdoor air pollution and have developed standards for measuring the type and amount of some serious air pollutants.
•
The air pollution brings us so many pain and burden, so next. • we should know How can we prevent the damaging effects of air pollution?
• In many countries in the world, steps are being taken to stop the damage to our environment from air pollution. Scientific groups study the damaging effects on plant, animal and human life.
•
Another type of pollution is the release of noxious gases, such as sulfur dioxide, carbon monoxide, nitrogen oxides, and chemical vapors. These can take part in further chemical reactions once they are in the atmosphere, forming smog and acid rain.
•
Only through the efforts of scientists, business leaders, legislators, and individuals can we reduce the amount of air pollution on the planet. This challenge must be met by all of us in order to assure that a healthy environment will exist for ourselves and our children.
