Automobile Emissions, CO and Asthma
Auto emissions are byproducts from the engine combustion process and from the vanishing of fuel. Despite the ever-growing number of vehicles on the road, studies show that ten to thirty percent of vehicles cause the majority of vehicle-related air pollution. This fact sheet lists some of the air pollutants associated with vehicle emissions. Because contact to these pollutants can cause serious health problems, the U.S. Environmental Protection Agency has established air quality standards to protect our health Asthma is an illness that causes the airways of the lungs to swell and narrow, leading to wheezing, shortness of breath, chest tightness, and coughing. Carbon monoxide is a colorless, odorless, toxic gas produced from the vehicle's exhaust as a result of imperfect burning. It constrains with the blood's ability to carry oxygen to the brain, heart, and other tissues. Unborn or newborn children and people with heart disease are in greatest danger from this pollutant, but even healthy people can experience headaches, fatigue and reduced reflexes due to CO exposure. Today I am going to talk about how automobile emissions produce CO and effect humans and lead them to Asthma same as many more health problems.
In the article, “Vehicle Exhaust to Health Problems” in New York Times, Exhaust from cars and trucks aggravates asthma in humans and may cause new cases as well as other respiratory diseases resulting in deaths, a self-originated institute described. People who live close to main highways are mostly affected by air pollution mostly lungs problem, and many other health problems. About 30 to 40% percent poor and lower class population are more affected than people live away from c...

Driving emits particle pollution, which increases the risk of heart disease, lung cancer and asthma. Particle pollution is processed in two ways, either mechanical or chemical.
Air pollution by definition is foreign particles in the air that do not belong there. Several creep worthy pollutants that come from cars are: hydrocarbons from a car 's exhaust ( a toxic compound of hydrogen and carbon, nitrogen oxides, particle matter,when the carbon in fuel doesn 't burn completely. These pollutants have been linked to be contributing to heart disease, potential premature babies, birth defects, eye irritation, and cancer. Scientists believe air pollutants can also lead to global warming. (Brinson, n.d., p3)
Asthma is a disorder of the respiratory system in which the passages that enable air to pass into and out of the lungs periodically narrow, causing coughing, wheezing, and shortness of breath. This narrowing is typically temporary and reversible, but in severe attacks, asthma may result in death. Asthma most commonly refers to bronchial asthma, an inflammation of the airways, but the term is also used to refer to cardiac asthma, which develops when fluid builds up in the lungs as a complication of heart failure. This article focuses on bronchial asthma.

Car fumes, smog and serious air pollution can cause serious asthma attacks with coughing, chest pain and shortness of breath. All of these factors can restrict the air passages, which is a sign of asthma.
Gasoline fueled cars produce a number of pollutants. The most damaging pollutants that come from gasoline fueled cars are particulate matter. Particulate matter is a sequence of organic materials and inorganic substances. It includes ingredients such as lint and minerals. Nitrogen dioxide, produced when fuel is burned at high temperatures, can cause damage to the lungs and cause chest pains. One might ask, “Why are Americans still driving gasoline cars?” knowing the damage that they are subject to cause. I personally maintain that the government should push people to p...
A case study was conducted in Los Angeles County, where researchers studied how near-roadway traffic attributed to the source of asthma. The results of the case study revealed that 27,000 cases of childhood asthma in Los Angeles County were attributed to air pollution from nearby traffic. These cases were of children that lived within 75 meters of a major roadway. The two main air pollutants in the Los Angeles County region that triggered and exasperated asthma and asthma symptoms were nitrogen dioxide and ozone. However, air pollution is just one aspect that has contributed to the increase in childhood
Air pollution has become a significant problem in the US as well as the world over years. It’s the result of variety of sources like industrial, agriculture, mechanical and transportation. Sadly, transportation which releases a great amount of carbon dioxides, nitrogen oxides and other toxicity is proven the leading cause of air pollution. There are several transportation factors that contribute to air pollution in the US.
When an engine burns diesel fuel, a harmful byproduct is produced; the byproduct can be referred to as particulate matter, diesel exhaust, or soot (Diesel Engines and Public Health; Health Effects of Diesel Exhaust). People are exposed to this mixture of toxic gases and miniscule particles simply by inhaling air, which allows the soot to enter the lungs (Health Effects of Diesel Exhaust). There are immediate health effects as long as prolonged health effects (Diesel Engines and Public Health; Health Effects of Diesel Exhaust). Immediate effects include irritation of the eyes, nose, throat, and lungs; coughing, light headedness, headaches, and nausea can also occur (Diesel Engines and Public Health; Health Effects of Diesel Exhaust). Some of the prolonged effects are respiratory illness, cardiovascular illness, cancer, and or premature death (Diesel Engines and Public Health; Health Effects of Diesel Exhaust). While everyone is exposed to the pollution given off by diesel engines, children, the elderly, and those with respiratory complications are most likely to be affected by diesel pollution (Diesel Engines and Public Health). In conclusion, diesel emissions are not only harmful to the environment, but they are also very harmful to
Health effects from diesel exhaust is mainly related to the respiratory and cardiovascular systems with the central airway being the most affected. Diesel exhaust can lead to the development of specific diseases that can have a lasting impact on a person. Barath’s article says, “…Recent studies have also suggested a role for pollutants in the development of both asthma and COPD” (1). Asthma and COPD are both diseases of the central airway. They are chronic conditions that affect individuals for a lifetime. Diesel exhaust does the more damage to the respiratory system of children than it does to adults. Oehha’s article says, “Because children’s lungs and respiratory systems are still developing, they are also more susceptible than healthy adults to fine particles”. When children’s bodies are still developing, the environment around them has a larger impact on them. Pollution’s affect on children is so drastic because it can limit the body’s ability to farther
The exhausts of vehicles, internal combustion engines, are a main source of emissions. Before 1900s, this severe problem was not recognized due to the small numbers of automobile. However, this problem became bigger with the increasing of cars due to the increase in populations. By the 1940s the problem of pollution first appeared in the USA, Los Angeles, due to the high numbers of cars and population. By 1970 the problem of emissions was clearly recognized in most American cities which might indicate that the internal combustion engine is the

What is air pollution? According to the experts, the presence into the air of a substance which has harmful or poisonous effects is termed as air pollution. The presence of Air Pollution is countries such as the US comes unsurprisingly to everyone. Being one of the most industrialized countries on earth, air pollution is one of the environmental issues that we just have to deal with. However, a statistic which may take the people by surprise is that among states such as New York, California and Indiana, it is Maryland which has managed in registering the highest number of deaths from Air pollution in the United States. After multiple study conducted by various institutes, it has been concluded that motor vehicles, and industrial smokestacks contribute to the death of 113 people per 100,000 per year in Maryland, with Baltimore and Montgomery Village topping the list with 130 deaths per 100,000 people.
The effect environmental factors have on the asthmatic populations can be better understood through the underlying cellular and molecular mechanisms (Holt, 1998). There has been extensive research over several decades in humans and animals yielding studies on mechanisms by which ozone exerts its effects. There are two main mechanisms by which asthma inflicted persons are more susceptible to adverse effects of ozone than to those without asthma. The first is that those with preexisting asthma might be more sensitive to ozone. Therefore, they experience respiratory symptoms and lung function changes common to all, but either at a lower concentration or with greater magnitude (U.S. EPA, 2014). Secondly, increased airway reactivity induced by ozone exposure may result in the worsening of a person’s underlying asthma status (U.S. EPA, 2014). Furthermore, repeated exposure to high levels of ozone concentration has been linked to new-onset asthma; individuals without preexisting asthma develop symptoms due to sensitization. Controlled exposure and some epidemiologic studies have demonstrated this response. Concern for excessive ambient ozone levels arises from ground-level ozone’s ability to cause acute respiratory response, significant lung capacity diminishment in at least 10-20% of healthy adults, pulmonary inflammation, impaired immune system,
The earth cannot lose its greenhouse gases quickly , and we keep adding to them. We do detect the same issue in the exhaust released from different factories, industries and from different types of vehicles. Grunig’s study found the following “First-responder immune cell types, such as alveolar macrophages and dendritic cells, are stressed and activated by air pollutants, such as diesel exhaust particles”.They do aswell release a large amount of carbon into the atmosphere and it causes a lot of problems to every single person that lives in a polluted area. The ignition of gasoline and other fuels in automobiles, trucks, and jetairplanes produce the most familiar pollutants, nitroge oxides, gaseous hydrocarbons and carbonmonoxide, likewise particles of an element like lead. When nitrogen oxides fuse with hydrocarbons they form different types of pollutants. In cities where transportation is the leading cause of pollution, nitrogen dioxide colors the sky brown, because the nitrogen dioxide has connected with other forms of pollution and water vapor to produce
