Extract of sample "Air Pollution"

Download file to see previous pages Air pollution emanates from air pollutants. These are substances that have adverse effects on the natural ecosystem when released into the atmosphere. The air pollutants can be liquid droplets, gases, or solid particles. The pollutants are either generated through the natural processes or by the action of human activities. One of the commonest natural sources of air pollution is the volcanic eruption. The gases emitted through volcanic activities may contain toxic pollutants such as sulphur dioxide and carbon monoxide.
The human activities that cause air pollution are mainly due to industrial production. Many modern factories emit sulphur dioxide through the production processes. The pollutant can also build up in the air due to the reaction of other gases such as sulphur monoxide with oxygen. In other words, the presence of oxygen in the air causes pollution after some non-polluting gases react with oxygen (Haerens 12). Sulphur may react with oxygen in a chain of processes leading to the emission of sulphur dioxide. Similarly, oxygen may react with carbon in a chain of reaction processes leading to the emission of carbon monoxide, an air pollutant.
The other source of air pollution is the oxides of nitrogen. They result from human activities, especially due to motor vehicle exhausts. Some vehicles are not fitted with the required catalytic converters to convert the oxides into the non-polluting nitrogen gas. When the oxides of nitrogen combine with those of sulphur in the atmosphere, the air becomes unpalatable and unsuitable for human health (Ayres, Robert & Roy 4). The result is the outbreak of skin cancers and other infections associated with the pollutants. Likewise, the emission of carbon dioxide into the atmosphere is directly associated with global warming. The gas causes greenhouse effect that leads to the preservation of more heat in the earth’s atmosphere.
