A fleet of vehicles will have far reaching impacts; perhaps best known by the general public is the impact on air quality. Air pollutants may be released in a number of ways: first through evaporation during fueling, second through tailpipe emissions while a car is running, and third through chemical reactions occurring with byproducts or unused components emitted into the atmosphere.(Motor vehicles and toxic air pollutants. 2008) Typical chemicals released include benzene, toluene, xylenes, diesel particulate matter, and volatile organic compounds.(Motor vehicles and toxic air pollutants. 2008) In addition, formaldehyde and acetaldehyde may be produced in reactions with the air. (Motor vehicles and toxic air pollutants. 2008) While there are large variations in the composition of air in various locations due to urbanization and other factors, the EPA’s national databases suggest mobile causes as the primary sources of carbon monoxide, lead, and volatile organic compounds in the atmosphere.(Air emission sources. 2011) More specific information may be found for individual states. For example, in Maine the amount of carbon monoxide in the atmosphere is 60% contributable and nitric oxide is nearly 80% contributable to mobile emissions.(Effects of vehicle pollution. 2011) In New Hampshire, data suggests that approximately 40 percent of human health risk from some source of air pollutants comes from mobile sources. (Motor vehicles and toxic air pollutants. 2008) Many of the fleet air pollutants are associated with negative health consequences. For example, benzene, formaldehyde, acetaldehyde, and diesel particulate matter are all suspected carcinogens.(Air toxics from motor vehicles.

Air pollution results from high concentrations of chemicals and particulate matter that pose a threat to human health, ecosystems, and manmade materials. Pollutants can be solid particles, liquids, or gases and are produced by human sources along with natural sources. Pollution from natural sources tend to become diluted and dispersed without causing major harm, whereas pollutants resulting from human sources tend to be more localized and a more serious problem. Scientists categorize air contaminants
Every year millions of American’s purchase chemicals intended to clean their home, remove weeds from lawns, and promise to eradicate various insects and other household pests. It is a deadly love affair with scientific advancements to create larger crops, more appealing food items and the promise of cleaner environments. Yet until recent years and the noticeable focus on organic and natural foods, very few have questioned these advancements. Rachel Carson was one of the people who had the courage
Characters as Portrayed Through Themes and Images in The English Patient While the four main characters of The English Patient are extremely powerful, and important to the reader's understanding of the story, they cannot stand alone without the patterns of imagery, symbolism and metaphor which underpin the text, and offer a complexity which extends beyond the literal level. These patterns reveal information about each character, and provide significant links between characters and ideas
Air Pollution is when a poisonous or a harmful substance is released in the air. There are many form of pollution but air is one of them, it only occurs when dust, harmful gases or smoke enters into the atmosphere and makes it hard for species like plants, animals and humans to live in a difficult situation because of the dirty air.Air Pollution is classified in two sections, invisible air pollution and visible air pollution.. Hence any substance that makes it difficult for the living things that
(2010) primary pollutants are emitted directly to air. They are chemicals released directly into the air in a harmful form and 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. Once emitted into the atmosphere, some of these primary pollutants can be altered by light energy, heat or the presence of other chemicals (e.g. oxygen) to form secondary pollutants. Primary pollutants
Air is really important for our survival. Air gives us oxygen which is essential for our bodies and our organs to live. It is the most essential element for all living organisms and yet, most humans play a big role on polluting this essential resource and this means air pollution occurs. According to the Geoplanet.org, air pollution is the addition of harmful substances to the atmosphere resulting in damage to the environment, human health and quality
Introduction: Air pollution is among the critical challenges facing modern societies and is one of the most pressing environing mental problems. Air pollution is accountable for major harmful effects on human strength, animal survives, natural ecosystems and the man-made environment. It is also responsible for climate change due to the improved greenhouse effect, acid rain, and the reduction of the ozone layer that inaugurate important global environmental problems. Air pollution occurs both outdoors
Air is an important aspect of our lives that allows us to live on the planet Earth. Without air, we could not survive. As humans, we rely on air to survive, so the quality of our air should also be important to us. “Adults breathe in about 10-20 cubic meters of air everyday. That is about twenty-thousand breaths. Children breathe almost twice that amount…” (B.C. Air Quality). Air has so much to do with the health and survival of many living organisms on this planet. Therefore, in this paper, we
Poor Air Quality in Fresno – Cause and Impacts Definition of Air Pollution Today, our environment faces air pollution; however, some of us are still not aware of it. It is a serious matter because it is all around us, and it causes harm to every single one of us; it might not be as evident in certain areas as others, but it is still present and affecting us in numerous ways. Air pollution, as defined by the World Health Organization (WHO), is the contamination of the indoor or outdoor environment
Atmosphere as a Result of Air Pollution Introduction With the great concern surrounding the destruction of the earth’s atmosphere due to air pollution, the immediate and direct harm caused to the human body is often over shadowed. While many are aware that our careless use of hazardous chemicals and fossil fuels may leave the planet uninhabitable in the future, most over look the fact that they are also cause real damage to our bodies at this moment. Such pollutants cause damage to our respiratory
major air pollutants in the atmosphere are causing damage to our waters and land. The increase of garbage and waste in urban areas, such as cities, are beginning to look like huge landfills, acid rain is causing forests and buildings to deteriorate, and finally ozone, which is caused from primarily transportation, is slowly suffocating the populations it affects. My area of the problem was the acid rain problem and how we are trying to solve it. The first thing I will discuss is major air pollutants
among developing countries (Petru, Alexis). Air pollution analyst and environmental chemist are two careers that focus on improving our environment to make it safer to live in. Air pollution analyst sample and analyze data collected from polluted air. Once they discover or have a theory on what is causing the pollution, the air pollution analyst works with other scientist to create future techniques for reducing air pollution. In order to become an air pollution analyst, one has to have a Bachelor’s
Relationships between Asthma and Air Pollution Professor’s comment: This student’s research paper synthesizes the results of a well-selected group of articles that explore relationships between asthma and air pollution. That laboratory science is at base a social enterprise is nicely exemplified by the focus of the studies she reviews. In drawing from the articles she reviews and in organizing her paper, the student maintains a good balance between discussing air-borne pollutants themselves and their physical
insect or pest killers, and fertilizer dust can emit harmful chemicals into the air and causes air pollution as well. We may fall ill if we breathe in any of these products. A lot of activities that we as humans do everyday result in air pollution. But, who does it effect? Are we, as humans, safe? Air pollution is a problem for all the living. People that are active outdoors are more likely to retain air pollutants. Air pollution can cause serious health effects on the population, from an eye irritation
environment of a substance or thing that has harmful or poisonous effects.” From 1960s through the 1980s, studies have showed that air pollution affects our health (C. Arden Pope III). Studies have shown that the effects of air pollution can lead to respiratory disease, death, and cardiovascular problems. The Clean Air Act requires that the EPA regulate these six common air pollutants; ground-level ozone, carbon monoxide, sulfur oxides, nitrogen oxides, and lead (Environmental Protection Agency). Ground-level
