Anybody lucky enough to be living in Montana might view all the concern about air pollution as a mystery. It is different when you find yourself located in a metropolitan area, where you are able to see the air, and it is hard to even take a deep breath. A lot of the world is filled with air pollution, and even locations that don’t seem to have any, are getting it from the rest of the world.
The air is loaded with things that are bad for people, such as carbon monoxide, sulfur dioxide, nitrates, lead, ozone, secondhand tobacco smoke and particulate matter. This is actually a catch-all phrase for something which has many origins, like road dust, the generation of power, emissions from vehicles as well as many industrial emissions. They could be from volcano’s, mold, forest fires, pollen’s, and many other sources that make the air rather dirty. These kinds of particles come in various sizes, composition and origin, and one of the biggest components is vehicle emissions. The worsening air pollution conditions tend to be a result of the crowded streets, especially in the biggest cities around the world.
It’s not possible to smell it, you can’t see it, but if the air is polluted you’ll find it present in large quantities – carbon monoxide. It’s traceable back to the combustion process in vehicles that run using gasoline, and the smoking of cigarette’s. It is harmful to the body, as it reduces the level of oxygen, and high enough levels are fatal. Respiratory conditions are increasingly being caused by carbon monoxide, even being absorbed by the body in small amounts over a long period of time. A lot of the world’s health issues are caused by ingesting carbon monoxide. The negative consequences of air pollutants because of cars and factories are borne out by many studies.
It is clear from the studies that from one city to another the pollutants discovered to be present and their effects can be different. Contaminants from traffic were found to be the reason for an increased mortality rate, in an eight year study involving five thousand adults. People living near to a busy road have a greater chance of dying from a cardiovascular disease, such as a heart attack. The life expectancy of individuals dwelling in the worst-polluted cities of the US will be cut by 2 to 3 years, directly as a result of the pollution carried in the air. The decision of experts is that a cardiovascular event, resulting in death, will happen to people even if they only have short-term exposure to particle pollution at enhanced levels.
In locations where the particle pollution is in increased concentrations, there are definitely more admissions to hospitals for various cardiovascular and pulmonary diseases. Life expectancy will be reduced by several years due to living in places where the particle pollution is elevated. We must conclude that if matters stay unchanged, the future for American people looks bleak . Far better regulation of the pollutants coming from vehicles is necessary if we want future generations to enjoy a healthier environment than us.
