Autos As Automatic Pollutants

"Green cars now so that my daughter will have places to drive at tomorrow." This is a clamor of an American father. Air pollution is everywhere and it is a big problem for most societies. 

Air pollution is composed of many environmental factors. They include carbon monoxide, nitrates, sulfur dioxide, ozone, lead, secondhand tobacco smoke and particulate matter. Particulate matter, also known as particle pollution, is composed of solid and liquid particles within the air. It can be generated from vehicle emissions, tire fragmentation and road dust, power generation and industrial combustion, smelting and other metal processing, construction and demolition activities, residential wood burning, windblown soil, pollen, molds, forest fires, volcanic emissions and sea spray. These particles vary considerably in size, composition and origin. 

As mentioned vehicle emission is one of the biggest components. Busy and crowded streets of the United States contribute a lot to the worsening of the air pollution problem. 
Carbon monoxide is a major component of air pollution. It is colorless, odorless and highly poisonous gas. It is associated with combustion reaction in cars and other vehicles same with cigarette smoke. Carbon monoxide is harmful because when it is received by the body, the level of oxygen decreases. High levels of CO are a threat to one’s life. Small amounts of CO if being absorbed by the body in a long span of time will still cause respiratory illnesses. Too much exposure may lead to malign health problems. 

When you go to streets, there are these cars blowing out too much dark smoke. Studies show that there is a very big negative impact caused by pollution from
Cars and other air pollutants. A study explains that a person’s exposure to poisonous components of air pollution may vary as much within one city as across different cities. After studying 5,000 adults for eight years, the researcher also found that exposure to traffic-related air pollutants was more highly related to mortality than were city-wide background levels. For example, those who lived near a major road were more likely to die of a cardiovascular event. 

Some research has estimated that people living in the most polluted U.S. cities could lose between 1.8 and 3.1 years because of exposure to chronic air pollution.

This has led some scientists to conclude that: 
Short-term exposure to elevated levels of particle pollution is associated with a higher risk of death due to a cardiovascular event. Hospital admissions for several cardiovascular and pulmonary diseases rise in response to higher concentrations of particle pollution. Prolonged exposure to elevated levels of particle pollution is a factor in reducing overall life expectancy by a few years. These facts are really telling us what future awaits Americans if this situation continues. Indeed, a need to regulate vehicle smoke is needed not only for the welfare of the present time, but for the future.
