PM 2.5 can be described as small, invisible particles that affect and damage the respiratory system (Louise Watt, 2013). Air pollution has turned out to be a major disaster in China due to the nation`s rapid pace of industrialization, explosive growth in car ownership, coal power, and disregard of environmental laws. Needless to say, this condition gets worse in winter because of heating activities. A study was done in 2012 by environmental organization Greenpeace (2012) examining the health effects of air pollution projected that poor air quality causes deaths of nearly 8,600 people in the Chinese cities of Shanghai, Guangzhou, Xi’an, and Beijing. This has triggered environmental experts and Doctors to expose the fact that PM 2.5 is capable of penetrating body tissues and cause serious health problems such as lung diseases and the inflammation of human alveoli. Additionally, it enters the human blood circulation and infects the cardiovascular system leading to a significant increase in mortalities due to cerebrovascular, cardiovascular, cancer, and respiratory diseases. For instance, hospitals in Beijing such as Tianjin United Family Hospital have shown a rise in the number of patients being treated with respiratory diseases by 50% (Greenpeace, 2012). Correspondingly, a study carried out by the American Heart Association in 2010 shows that temporary exposure to PM 2.5 over a period of a few days or weeks can lead to cardiovascular disease associated death and nonlethal occurrences that engross heart diseases, stroke, and myocardial ischemia. On the other hand, constant exposure to high concentrations of PM 2.5 in the environment reduces the life expectancy of a human being by 10% over the years. Notably, PM2.5 is most usually associated with cardiovascular deaths as shown by most cohort studies. Notably, the focus on the above statement of PM is basically correct.
