Answer:
Air pollution caused by cars is one of the biggest challenges for air pollution that environmentalist are working with now a days. In the 1920s the first car was invented with a combustible engine. Henry Ford was the creator and also later founded Ford Motor Company. The invention of the car was known to be one of the biggest inventions in the 1920’s it made transportation a lot better and also added to the economy to give it the boost it needed. The Ford Motor Company came out with America’s first affordable car, called the Model T. (anglefire) To this date there is no exact number of how many cars have been made or sold in the USA from when they had first been invented. A lot of the reasoning behind why there is no perfect number is mainly because not all of them are registered. On the roads today there are around 250 million register vehicles on the roadways. The U.S. Department of Transportation says that 2008 there were 136 million cars, 110 million trucks and close to 1 million buses totaling up to 247 million cars trucks and buses that are on the roads and registered. These statistics do not include cars that are unregistered and sit in junkyards. The U.S. D.O.T states the roughly 16 million new cars are bought yearly. (Wikianswer)Yes, automobiles do make life a lot easier to transport our self’s and objects but they do have an effect on us. Through many scientific test research has shown that it pays a big toll on the environment. These tests have provided us with answers to show the emissions from a car that are put into the atmosphere can be directly connected to human health issues.The exhaust on a vehicle is what produces these emissions. Once they leave the exhaust and enter the air they can be breathed in and enter the blood stream and into the body’s major organs. Diesel fueled vehicles seem to be more of a problem to us and the environment but they but they can have major effects on the body. Some of these harmful fumes that are put out into the atmosphere by a vehicle are carbon monoxide, nitrogen dioxide, sulphur dioxide, benzene, formaldehyde, polycyclic hydrocarbons, and lead. Although studies have clearly connected emissions to a wide span of health problems in the United States, the risk to each individual is very difficult to grasp as it varies. There is no doubt in anyone’s mind that the mores you are exposed to these toxic fumes that u will be put into a greater risk. (BBC)People who already expierance respiratory problems are at a much greater risk then people who don’t suffer from asthma for an example. The biggest and most obvious of where the emissions will take their toll on a human would be there respiratory system. In the UK air pollution cause by vehicles is said to be responsible for 24,000 early deaths every year. Many of these premature deaths have to deal with asthma, bronchitis and many other that can be brought upon someone by vehicle emissions. (BBC)Fumes from an exhaust on a car put out many toxic chemicals that affect the blood and coronary system. Studies show that about one in every 50 heart attacks are caused or triggered by air pollution. (BBC)All the chemicals found in exhaust fumes like lead, benzene, and carbon monoxide can all be connected in a harmful way to a person’s blood. When more lead enters the bloodstream it can change around the formation of the red blood cells in your body. It is directly connected to damaging the red blood cells membranes and the metabolism of that cell which may cause it to have a shorter life and can happen to all the red blood cells as well. This can eventually lead to lead anemia. Anemia this when your body has a shortage of cells and this reduces the body’s ability to circulate oxygen through the body. (BBC)Benzene is a chemical that is also found In the emissions put out through the exhaust can have a major effect on bone marrow also damages the way in which the body can produce more red blood cells and their development. Carbon monoxide poisoning is a very big issue that most of us have heard of, and we all even protect ourselves from this deadly, highly poisonous, odorless gas. Yet most of us most likely do not realize that your very own family vehicle helps contribute to the two-thirds of the world’s carbon monoxide gases that enter our world atmosphere. “Carbon monoxide poisoning is very to suffocation. Carbon monoxide binds to the hemoglobin contained in the red blood cells 200 times more effectively then oxygen, and so can dramatically reduce the ability of the cells to transport and release oxygen to the tissues of the body.” (www.bbc.co.uk) This can cause many problems with main organs and within minutes of being surrounded by the fumes you can die.
