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.
Imagine a young child competing with his or her fellow classmates during recess and immediately losing the ability to breathe normally. He or she stops in the middle of the competition and falls to the ground while holding his or her chest trying to find air. When you are young, being able to keep up with your peers during recess and sporting events is very important, however, having asthma restricts this. Asthma has a significant impact on childhood development and the diagnosis of asthma for children 18 years and younger has dramatically increased over the years. Asthma is known as a “chronic inflammation of the small and large airways” with “evident bronchial hyper-responsiveness, airflow obstruction, and in some patients, sub-basement fibrosis and over-secretion of mucus” (Toole, 2013). The constant recreation of the lung walls can even occur in young children and “lead to permanent lung damages and reduced lung function” (Toole, 2013). While one of the factors is genetics, many of the following can be prevented or managed. Obesity, exposure to secondhand smoke, and hospitalization with pneumonia in the early years of life have all been suggested to increase children’s risk of developing asthma.

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.
Fortunately, Mexico City is doing a lot in response to the problem, including vehicle control, mass transit improvements, required industry emission reductions, and investing in research and education programs. Regardless of these actions, however, Mexico City’s air quality is still significantly affecting the quality of life for its residents, and the city must continue to make changes in order for real progress to occur. Vehicles are responsible for up to eighty percent of air pollution in Mexico. There are close to four million automobiles, buses, and trucks in the city, the average of which is ten years old, and thus in poor repair with ineffective emission controls. Emissions are increased by the excessive traffic compressed into narrow streets with few parking spaces, requiring low-speed cruising (Collins, 125).
Relevance: Air pollution is something that everyone should be concern, especially if we’re advancing a lot in technology, especially in vehicles and the importance of our air or the environment.

• SUVs can spew 30 percent more carbon monoxide and hydrocarbons and 75 percent more nitrogen oxides than passenger cars.
There is no question that pollution from automobiles is a major problem in industrialized countries and is increasing in developing nations. And the number of cars is increasingly rapidly: in the United States, the automobile population has increased 6X faster than the human population and 2X faster than the number of new drivers (Motavelli, 2000). At the same time, the average fuel economy of the 2001 fleet decreased to 20.4 miles per gallon, the same it was in 1980. This decrease is fueled by the growing trend in inefficient SUVs. As over 50% of the USA’s oil comes from overseas, the dangerous level of waste promoted by inefficient vehicles makes this more than simply an environmental issue.
There are many kinds of air pollution. The ones I want to talk about are the ozone, acid rain, carbon monoxide and toxic air contaminants. Ozone is formed when hydrocarbons and nitrogen oxide react in sunlight. Therefore, ozone is at its peak during hot summer days. Exposure to high levels of ozone can have serious consequences on your health. It can cause respiratory disease, loss of pulmonary elasticity, and premature aging of our lungs. Next, is acid rain, which occurs in the atmosphere in the form of sulfur and nitrogen oxide. These pollutants can have serious damaging affects on aquatic, forest and wildlife ecosystems, as well as deterioration of buildings. Carbon monoxide is another form of pollution. It reduces the blood?s ability to carry oxygen. If a human is exposed to higher levels, it can cause chest pains, angina attacks or even death.
In conclusion, air pollution affects the immune system, making it weak and vulnerable to certain bacteria, illnesses, viruses and foreign invaders. Common diseases that are affected the most include asthma and allergies. Air pollution in general has been seen to modify the immune system's handling of particular allergens. The exposure to toxins like dioxin can cause serious health problems for people. Having long-term exposure to this toxin is connected to weakening of the immune system, as well as the nervous system, endocrine system and certain reproductive functions. Hence, everyone has a particular level and exposure of dioxins in the body. Improving air quality is the key answer to avoiding any type of development of disease, but it is a long term goal that will require the help and commitment at the national and global level.
Car pollutants cause immediate and long-term effects on the environment. Car exhausts emit a wide range of gases and solid matter, causing global warming, acid rain, and harming the environment and human health. Engine noise and fuel spills also cause pollution. Cars, trucks and other forms of transportation are the single largest contributor to air pollution in the United States, but car owners can reduce their vehicle's effects on the environment. Car pollution is one of the major causes of global warming. Cars and trucks emit carbon dioxide and other greenhouse gases, which contribute one-fifth of the United States' total global warming pollution. Greenhouse gases trap heat in the atmosphere, which causes worldwide temperatures to rise.
they create many breathing and heart conditions like cancer and other threats in the body, that is why children who are exposed through air pollutants are most likely to have pneumonia and asthma.
Every other day a new industries are being set up, new vehicles on roads and trees are being cut to make way for new homes. All of them, indirect way lead to increase in CO2 leads to melting of polar ice caps which increase the sea level and pose danger for the people living near coastal areas. Pollution can have an impact in our health not only affects people with impaired respiratory system such as asthmatics, but very healthy adults and children too. Exposure to pollution for 6 to 7 hours, even at relatively low concentrations, reduces lung function and induces respiratory inflammation and, healthy people during periods of moderate
