As the whole world evolves rapidly, pollution has become more and more severe. In modern society, pollution is defined as “ the introduction of contaminants into a natural environment that causes instability, disorder, harm or discomfort to the ecosystem” ( Wikipedia, 2012 ) or the addition to the ecosystem of something that brings detrimental effects. Dating back to 1272, pollution was first known by a British called King Edward. As a matter of fact, the word “ pollution” was not so familiar to people some centuries ago. However, there is no denying that due to pollution, the quality of living condition of human beings reduces to a lower level. Furthermore, some of the citizens who live in the regions which are seriously polluted can not bear the disgusting and nasty pollution any longer and consider it as a serious threat to not only their personal health but also the quality of their lifestyle. Fortunately, the government all over the world has lain more emphasis on finding out effective solutions to pollution in recent years. There are totally three specific forms of pollution: solid particle, liquid droplets and gases which can be either natural or man-made. Speaking of different types of pollution, there are numerous such as noise pollution, visual pollution, light pollution, thermal pollution and so forth whereas as is surveyed the three most severe kinds of pollution are air pollution, water pollution and land pollution. However, from the overall impact on human beings and the whole world, air pollution, ranked the first according to the harmful and negative effects on the environment, is no doubt the worthiest topic to be discussed about.
Air pollution is “ the human introduction into the atmosphere of chemicals, particulate matter, or biological materials which causes harm or discomfort to humans or other living organisms or damages the environment” . ( Wikipedia, 2012) Under the authority of statistics in 2011, China and Azerbaijan are the two countries which suffer most from air pollution. One of the major contributors to air pollution in both countries is motor and vehicle emissions. Another primary source of air pollution in China is coal combustion in plants whereas fetid water emitted from the process of drilling the oil fields is an important reason why Azerbaijan is the world’ s dirtiest city. For instance, Shanghai, one of the biggest Chinese cities, surrounded by a belt of factories is consequently in bad quality of air. Fortunately, there has been some effective prevention projects and programs for the sever air pollution such as the Environmental Projection Department which has taken comprehensive measures to reduce air pollution such as regulating environmentally for cars in use and innovating clean technology for vehicle fuel.
In the following, the causes, effects, solutions, programs and prevention projects will be introduced and the two countries, China and Azerbaijan will be compared in various aspects of air pollution mentioned above.
According to China’s own evaluation, the air quality of the 338 cities in China is considered seriously and moderately polluted. On the basis of a survey in Time Magazine, the Chinese cities Linfen and Tianying are the two most polluted cities all over the world. Since air pollution has become the most serious problem in China and Azerbaijan, there are quite a lot of important reasons and causes of air pollution. One of the major contributors to air pollution is motor and vehicle emission in China. As more and more people have started to use cars in recent years, a lot more chemicals such as carbon monoxides, sulfur dioxide and nitrogen oxides which can be regarded as common pollutants that influence different levels of air pollution. Another primary source of air pollution in China is coal combustion. There is no denying that coal is one of the main source of the country’s energy needs, so...
