Air pollution in U.S.A vs Air pollution in China
Has it ever happen to you to wonder all week for that special weekend when you will leave the city behind and head for the country? Which is the reason? It’s easy. You can finally breathe some quality air. So the aim of this research paper is to compare the air pollution in two countries : USA VS. China. I will discuss their similarities and differences in regards to types of air pollutant, the health effects and the government policies in both these countries.
Has air pollution worried humanity only recently or this problem has existed even earlier in the history? The truth is air pollution has always been a problem but with the hectic development of technology in these last centuries taking it seriously has become a necessity worldwide. This wave of concern has not left untouched even these two technology superpowers as U.S.A and China. Which are these dangerous particles that we inhale in the air we breathe? The mostly common are Carbon Monoxide (CO),Nitrogen oxides (Nox), Sulfur dioxide (SO2) and Lead (Pb). Carbon Monoxideis the product of incomplete combustion of hydrocarbon which is released in the air as the result of motor vehicle emission. In U.S.A strict control strategies have been taken to control such emissions during the period between 1983 to 2002 ,which resulted in a decrease of emissions for km travelled by 95 percent. Another harmful substance is the Oxides of nitrogen which arises from the combustion of both mobile and stationary sources. The Environment Protection Agency (hereafter referred to as EPA) has declared that the levels of NOx have been decreasing during the last 20 years. On the other hand as the result of the large use of coal and oil in Chinese industry, their combustion has brought the emission of SO2,making it one of the most problematic particle present in the air. As it was mentioned in Challenges for China and USA by...
