Air pollution is the introduction into the atmosphere of chemicals, particulates, and biological matter that cause harm to humans, other living organisms, or cause damage to the natural environment. Stratospheric ozone depletion (contributed to air pollution) has long been recognized as a threat to human health as well as to the Earth’s ecosystems. The Earth is capable of cleaning itself of a certain level of pollution, but man-made pollutant have become too numerous for the Earth’s natural mechanisms to remove. We are seeing the results of this overload in the form of acid rain, smog, and the variety of health problems that can be contributed to our environment. (Godish)…
This is intended as a study guide. For best results, I recommend studying all the material first, then filling out the worksheet “closed-book/notes” as if taking a test. When done, go back to your notes to check your answers.…
Air pollution is the introduction of chemicals, particulate matter, or biological materials that cause harm or discomfort to humans or other living organisms, or damages the natural environment into the atmosphere.…
Air pollution can cause many life threatening health problems. Many problems such as, lung cancer, asthma, and heart disease. Problems like these will be a huge burden to people, especially to kids who are still growing. These problems will threaten our lives and continue to deteriorate the human body. If air pollution isn't quickly taken care of, these health problems will increase and the human population will decrease.…
The average person breathes about three thousand gallons of air per day. Imagine if that air was dirty? Most of us take for granted the air we breathe, and don’t even realize that we are breathing in toxins. Most of us aren’t even aware of how polluted the air is and how unhealthy it can be for the average person to breathe it in. It can make breathing difficult for some people and it affects all living things. Air pollution is a major problem in the world today. There have been many laws passed regulating air pollution to protect our environment and all living things.…
Air pollution is a significant risk factor in the world for multiple health conditions. In currently, the world is getting a lot effect from the air pollution especially the effecting of humans. Humans can get a lot effect which can affect their health to be bad because the air is the most important of human living. Everyone needs the air for their breathing. The air pollution also has direct affect to the respiratory system of humans include loss of productivities, damage ecosystem.…
Air pollution – contaminants or substances in the air that interfere with human health or produce other harmful environmental effects. Read our “What is Air Pollution?” article for further information.…
Air pollution is a severe problem, especially for the United States. Air pollution is the contamination and harm to the atmosphere by substances like smoke and fuel exhaust. According to the World Health Organization, one-fifth of the population is exposed to hazardous levels of pollutants. Air pollution occurs when pollutants are released into the air and cannot be taken out by its natural process. This upsets the balance of the atmospheres natural cycle.…
The earth’s atmosphere is a constantly moving body of gases that encircle our planet. This body of gases known as air is a mixture, not a chemical combination, of a number of gases; that is, each gas retains its own characteristic properties. It consists of about 78 percent nitrogen; 21 percent oxygen, and carries along with it water vapor, clouds, dust, smoke, soot, and a variety of chemical compounds. The remaining one percent contains all the other gases including carbon monoxide, carbon dioxide, ozone, methane, and ammonia that contribute to harmful pollutants that are released into the air. Millions of tons of harmful gases are released into the air each year. According to The World Health Organization, 2.4 million people die each year from causes directly attributable to air pollution, with 1.5 million of these deaths attributable to in-door air pollution (World Health Organization, www.who.int). For the past several decades’ air pollution has become more of a health risk factor. What is air pollution? Air pollution is air that enters our atmosphere that contains undesirable substances such as gases, dust, chemicals, particulate matter, biological materials, fumes or odor in harmful amounts. That is, amounts which could be harmful to the health or comfort or humans and animals or which could cause damage to plants and materials. The use and release of certain chemicals can be of serious concern if they have significant impacts on human health or the environment. The substances that cause air pollution are called pollutants. An air pollutant is known as a substance in the air that can cause harm to humans and the environment. Pollutants can be in the form of solid particles, liquid droplets, or gases. In addition, they may be natural or man-made. Pollutants that are pumped into our atmosphere and directly pollute the air are called primary pollutants. Pollutants can be classified as primary or secondary. Primary pollutants are directly…
Air pollution is the contamination of the atmosphere by gaseous, liquid or solid wastes or by-products that can endanger human health, the health and welfare of plants, animals and the environment, or can reduce visibility or produce undesirable odours.

Air lets our living planet breathe—it's the mixture of gases that fills the atmosphere, giving life to the plants and animals that make Earth such a vibrant place. Broadly speaking, air is almost entirely made up of two gases (78 percent nitrogen and 21 percent oxygen), with a few other gases (such as carbon dioxide and argon) present in absolutely minute quantities. We can breathe ordinary air all day long with no ill effects, so let's use that simple fact to define air pollution, something like this:…
"Air pollution is any visible or invisible substance found in the air that is not part of the normal composition of air. Some air pollution is natural and has always been a part of the earth's history. However, over the past one hundred years or so, pollution created by humans has become a major environmental problem. Natural air pollution has been around for millions of year. Dust and a variety of gases from forest fires, volcanoes, and decaying material in rivers, oceans, and other bodies of water continually enter the atmosphere. Sometimes this natural pollution can have dramatic effects. Air pollution is a major factor in causing humans to get ill. Tuberculosis, bronchitis, heart and chest diseases, stomach disorders, asthma and cancers can all be traced to chemicals in the air. Pesticides and fertilizers release gases and particles into the air which poison people and kill animals."…
We need air in order for us to breathe. But on some reasons, the air that is physically needed by our bodies is now being polluted. The term "air pollution" is used to describe substances that are artificially introduced into the air. Air pollution stems from gases and airborne particles which, in excess, are harmful to human health, buildings and ecosystems. This chemicals particulate matter or biological materials that cause harm or discomfort to humans or other living organisms, or cause damage to the natural environment or built environment into atmosphere.…
According to encyclopedia air pollution is the introduction of particles, biological molecules or other harmful material into the earth atmosphere. Possible causing diseases, death to human, damage to other living organisms.…
On the other hand, air pollution is also a serious problem that many countries have to deal with. People need to think about the way to stop the spreading of toxic smoke to the surrounding environment. Actually, toxic fumes are caused by many industrial processes. It has been suggested that one way of helping to reduce dioxide and nitrous oxides is to stop burning coal in power stations to generate electricity. Therefore, people would live in healthier surroundings with no toxic smokes or gases.…
