Pollutants can be classified as either primary or secondary. Usually, primary pollutants are substances directly emitted from a process, such as ash from a volcanic eruption, the carbon monoxide gas from a motor vehicle exhaust or sulfur dioxide released from factories.…
As you can see, every day, a person inhales about 20,000 liters of air. Every time we breathe, we risk inhaling dangerous chemicals that have found their way into the air.…
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 the cause of release of chemicals, and particulates into the atmosphere which endanger human life and living matter on the earth by humans, human products and natural disasters. As the current era of modern industrialization progresses more and more waste of the results of their production become toxins which can be freely inhaled and fatal to mammals.…
Enough air pollution of the wrong kind, like carbon monoxide or hydrogen sulphide will kill people outright by poisoning them. Smog or particulates may cause cancer or trigger people to have asthma attacks in a lot of individuals (Consulting, 2005).…
We are living things that need to breathe, no doubt of that. Every few seconds we need to inhale a small quantity of air. Unfortunately, the air we breathe in has become more and more polluted owning to a multitude of factors such as: increase in number of vehicles, increase usage of synthetic materials for buildings and homes, lack of awareness towards potentially hazardous microorganisms such as fungi and so on. Air pollutants – any one of them, is undoubtedly a serious threat to our health. According to statistics conducted by the World Health Organization, the incidence of health problems such as asthma, bronchitis, sick building syndrome, pneumonia, all attributable to air pollution, have increased significantly over the past few decades.…
Pollution is the addition to the ecosystem of someting which has a detrimental effect on it. One of the most important causes of pollution is the high rate of energy usage by modern, growing populations.…
Air pollution can be defined as impureness of the air. Air pollution is all around us. It might not be as clearly visible in some areas as others but the fact is that air pollution is still there affecting us in some way, shape, or form. It has been known to cause illness and even death. Many people are not aware of this.…
Did you know that the average person inhales up to 20,000 liters of air every single day? Well a larger percentage of that is filled with dust and chemical particles that are harmful to us humans. 154.5 million people in the US, which is about half of the population, live in areas in which it is dangerous to breathe because of the smog and other chemical particles that are floating around in the air. We now live in a world where breathing, something we need in order to survive, can actually end up causing health problems or even death in some cases. According to the American Cancer Society, 15% of lung cancer cases are linked to air pollution and around 3 million people die because of it.…
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…
There are two main air pollutants; one is natural causes e.g. windblown dust, pollen, fog etc. and the other is that which we call people pollution. This is the most serious form of air pollution. One of the worst air pollutants which is affecting our environment today is Carbon Monoxide, a colourless, odourless gas caused by the incomplete burning of gasoline, oil, and wood. Low concentrations can cause dizziness, fatigue and headaches, while high concentrations can be fatal. Other pollutants such as Carbon Dioxide, Nitrogen and Lead have contributed to the deteriorating environment. We are all guilty of the overuse of same and, consequently, we all contribute to the pollution levels from which we suffer.…
Air pollution is a general term that covers a broad range of contaminants in the atmosphere. Pollution can occur from natural causes or from human activities. Discussions about the effects of air pollution have focused mainly on human health but attention is being directed to environmental quality and amenity as well. Air pollutants are found as gases or particles, and on a restricted scale they can be trapped inside buildings as indoor air pollutants. Urban air pollution has long been an important concern for civic administrators, but increasingly, air pollution has become an international problem.…
Definition Of Air PollutionAir pollution occurs when the air contains gases, dust, fumes or odour in harmful amounts. That is, amounts which could be harmful to the health or comfort of humans and animals or which could cause damage to plants and materials.The substances that cause air pollution are called pollutants. Pollutants that are pumped into our atmosphere and directly pollute the air are called primary pollutants. Primary pollutant examples include carbon monoxide from car exhausts and sulfur dioxide from the combustion of coal.Further pollution can arise if primary pollutants in the atmosphere undergo chemical reactions. The resulting compounds are called secondary pollutants. Photochemical smog is an example of this.…
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.…
We keep our houses clean. We take utmost care of our bedroom, making sure no dust rests on our polished furniture. From walls to carpets, everything in our house is neat and clean and perfectly maintained. Then why do we fail to keep our environment clean; maintenance of which is far more vital as compared to our home?…
