Air/Water Pollution Paper
There are many types and sources of air pollution. Air pollution is various chemicals such as gases, liquids, and solids that are present in the atmosphere in high enough levels to be harmful to humans, other organisms, or materials. There are two types of air pollutants known as primary and secondary air pollutants. Primary air pollutants are harmful chemicals that enter directly into the atmosphere due to either human activities or natural processes. Secondary air pollutants are harmful chemicals that form in the atmosphere when primary air pollutants react chemically with one another or with natural components on the atmosphere. The major classes of air pollutants is particulate matter which are dusts better known as solids and mists better known as liquids that are suspended in the atmosphere. Particulate matter scatters and absorbs light, therefore it reduces visibility. It can also corrode metals and erode buildings and sculptures. It eventually will settle out, but can remain suspended for many years. By inhaling the particles it introduces the chemicals into the body, but the smaller particles are worse because they get deeper into the lungs.
I am going to discuss two types of air pollutants which are carbon monoxide and sulfur dioxide. Carbon monoxide is an odorless, poisonous gas. It is produced by the incomplete burning of fossil fuels. The primary sources of carbon monoxide are cars, buses, trucks, some industrial processes, and small engines. Carbon monoxide interferes with the ability to carry oxygen. It slows down one’s reflexes and also causes drowsiness. In high concentrations, carbon monoxide can cause death. Sulfur dioxide is produced by chemical interactions between sulfur and oxygen. Sulfur dioxide primary source comes from burning fossil fuels. Sulfur dioxide contributes to acid precipitation as sulfuric acid. Secondary...
