Air Pollution Is Their Solution
Sunday, April 18, 2010
When did we first experience air pollutions? Could it have been in the A.D era when cave people built small fires to survive? Or has it become an issue since the early 80`s. No one will be able to specifically say but what we can attest to is that since the A.D era we have contributed several times over to Air Pollution. We risk breathing in dangerous chemicals every time we breathe. What is air pollution? It is defined as all contaminants found in the atmosphere and can came in the form of a gas or particle. It also is found indoors as well as outdoors. Pollutants can get trapped inside buildings causing indoor pollutants to become trapped for a long time. Air pollutants are both caused by naturally and comes from human activity. We humans have produced an increasingly amount of pollution as time have progressed through history. We account for the majority of pollutants releases into the air. Since it is air the pollutants are able to travel easily. This fact has made if a global problem. This is adiverse subject and has been an issue of conflict and global cooperation and participation. Tons of pollution also enters the air through evaporation. Evaporation come gas that turns into liquids. Examples of this would be gas stations, refineries and service stations. Up until recently environmental pollution problems have been local and minor due to our earth’s ability to purify problems and absorb miner quantities of pollutants. Since then we have become an industrialize society introducing moisturizers vehicles and the overgrowth of population has contributes toward our growing air pollution problem. Some areas suffer more than others. Cites have a larger amount of people which means more things like automobiles. A more rural area may have more use, in larger quantities, of coal. This makes both areas more vulnerable to problems that derive from air pollution. Primary pollutants from urban areas are usually carbon monoxide, sulfur oxides, nitrogen oxides, hydro carbons and particulate matter which can both a solid and liquid. The pollutants can cause serious health problems because they can dispense in high concentrations. For example, when there is a volcanic eruption massive injection of sulfur dioxide and particulate matters are releases into the air. Unfortunately we cannot escape Air pollution. We need to continue to find solutions to the problem. Will we ever live Air pollutant free? A question I am not sure how to measure. Humans and animals are affects by this issue. Our pollution is responsible for major health problems. And every year numbers that reflect how many people are affected to rise. There are so many different chemicals in the air we are bound to be infects in a negative way. Depending on what chemicals people are exposed to how long they are exposed and in what concentration they are exposed to will determine how sick they can get. Some students estimate that 50,000 people own are killed annually because of air pollution. Among those people how many were elderly? How many are children? Why is it that elderly people and children or more at risk than the average adult? This is another question that is left to one’s own interpretation. Diseases like bronchitis, lung cancer and heart diseases may appear in people that have been exposed to air pollutants. It is hard to know exactly what pollutants are responsible for causing sickness. Mixture of a variety of pollutants can intensify a sickness and that makes it hard to isolate which pollutant caused or effects. A critical factor in determining the potential harm that airborne pollution can cause to the population is the particle size. The size of the particle dictates how deeply into the lung the particle penetrates. Larger particles don’t penetrate deep in the lung and is effectively excreted. This minimizes the harm that the particle can cause....
