Air Pollution: A National Problem

Air Pollution: A National Problem with a Local Solution

By Emily Feldman

As a nation, our air is markedly cleaner that it was before the passage of the Clean Air Act nearly 40 years ago.  However, since that time, science has taught us that air pollution can be harmful at lower levels and less exposure than originally thought.  Tack on global warming and energy inefficiency to the problem, and we are now faced with escalating trouble, despite the growing efforts to reduce pollution sources.

It’s natural to want to blame big industry, factories and semi trucks for the air pollution, soot and smog that plague the country.  But when it comes down to it, there are many causes that affect our air quality.  While big industry may be a factor, each one of us has our own effect on the air we breathe.  Simple changes to our daily routine could have a huge effect on the air quality of our nation.

The first step to solving any problem is knowledge.  In order to conquer the beast, you must first understand how it came to be.  When it comes to air pollution, there are many different forms that exist.  The two most prevalent and widely known are ground-level ozone and particulate matter.  Ozone, a main component in smog, forms when heat and sunlight mix with emissions from sources such as smokestacks and tailpipes.  The molecule that is created (O3) is exactly the same as the ozone in the upper atmosphere that protects us from harmful radiation.  At ground level though, it is extremely dangerous.  It irritates the lining of the throat, nose and lungs causing wheezing, coughing, shortness of breath and pain.  Repeated exposure can scar lung tissue and cause chronic problems such as lung disease, heart attacks, diabetes and cardiovascular disease.

Particulate matter pollution poses many of the same health risks.  This type of pollution is caused when liquid droplets found in the air mix with solid particles such as dirt, soot, dust or smoke.  Some particles are emitted directly from a source like unpaved roads, smokestacks or construction sites, but most particles form in the atmosphere with chemicals emitted from power plants, automobiles and industries.  Particles come in many shapes, sizes and chemical compositions.  Some are big enough to be seen with the naked eye, while others can only be seen through a microscope.  Most particles are small enough to get deep into the lungs, aggravating asthma and bronchitis, irritating airways and decreasing lung function.  Like ozone, increased exposure to particulate matter pollution can also cause chronic bronchitis, lung disease, heart attacks and cardiovascular disease.

Now for the good part: the solution.  There are many simple things that we can each do to cut back on air pollution.  One major solution is using your car less.  This includes carpooling, using public transportation, combining trips, biking and walking.  The U.S. uses about half of the world’s gasoline, most of it going into individual cars, whose emissions are a big factor in air pollution.  When taking your car is the most sensible option, make sure your vehicle is properly maintained and trade in dirty diesel engines and gas guzzlers for more fuel efficient models.  Also, fill up your gas tank after 8 p.m. when the sun is less intense.  Never top off your tank - this only releases more emissions into the air.  Finally, conserve electricity because every bit you save adds up to less pollution from the power plant supplying it.  

There are many other ways in which you can help reduce pollution.  Additional tips and more information about improving air quality can be found at www.DoYourShare.org.   While this website is geared toward the population in Greater Cincinnati/Northern Kentucky, it offers pertinent information no matter where you’re located.  Furthermore, many cities have their own causes set up to fight air pollution on the local level.

Sure, tackling bigger sources of pollution will have to be done, but can you think of a better way than leading by example?  This is one problem that can be solved from the bottom up.

Air pollution causes me to have and suffer from hay fever it is mainly my eyes and also my nose that is most affected and for combating a tickly runny nose I find Flonase over the counter. Allergy Nasal Spray to be excellent. I have tried everything, and nothing works like it. Only thing I use now.Take note that you must use the medicine as directed

Air is the most important element of human environment. Man can't live a single moments without air. But we don't think that it is we who pollute this most vital element. Clean air is essential for life. Air is polluted in many ways. Smoke pollutes air. Man makes fires to cook his food.To make bricks burns refuse, melts pitch for road construction and burns wood. All these things produce heavy smoke and this smoke pollutes air. Railway engines, power houses, mills and factories use coal and oil. buses, tucks and cars use petrol and diesel oil. Again all these things create smoke and cause air pollution. The most serious air pollution occurs in big industrial areas where there are many mills and factories. serious air pollution also occurs in big cities where there are many buses, trucks and cars plying the street everyday. Sometimes men in big industrial area become so sick by inhaling polluted air that they cannot be cued. So proper measures and steps should be taken to prevent air pollution.

The World Health Organization states that 2.4 million people die each year from causes directly attributable to air pollution, with 1.5 million of these deaths attributable to indoor air pollution.

To minimize pollution is to conserve energy whenever possible while at home. Turn off lights in rooms not being used, turn off televisions, and unplug unused appliances.Thanks for posting this informative article about the pollution.

[Air Pollution Facts]

The air pollution can cause or exacerbate a number of serious diseases among inhabitants of an air polluted city. These diseases include Ischemic Heart diseases, stroke, hypertension, and a number of respiratory disease and birth defects. Those who are at highest risk of being affected by air pollution are children, the elderly and patients who already have diabetes, heart disease and respiratory disease. Air pollution can also affect fetus in the mothers womb.

Thanks for the great article. I agree that knowledge is the first step to solving any problem. I found some interesting air quality facts for my city at http://www.homefacts.com/airquality.html
