Air pollution is described as “a mixture of solid particles and gases in the air” (“Air Pollution” MedlinePlus). This form of pollution mainly occurs from the burning of fossil fuels, noxious gases from vehicles, manufacturing chemicals, ground-level ozone (a reactive form of oxygen and a primary component of urban smog), and tobacco smoke (“Air Pollution” National Institute...). These emissions suspend deadly particles around in the air that can remain in the environment for long periods of time. People exposed to high levels of air pollutants may experience “burning in their eyes, an irritated throat, or breathing difficulties” (“Basic Information”). Moreover, this pollution can lead to serious, long-term health concerns including accelerated aging of the lungs, lost lung capacity, decreased lung functionality, and developed diseases such as asthma, bronchitis, emphysema, and possibly cancer (“Health Effects”). Air pollution poses a threat to the majority of Earth’s population due to the fact that the average adult breathes in 3,000 gallons of air everyday (“Basic Information”). Outdoor air pollution is one of China’s most serious environmental problems. Because of the mass continued use of coal, China’s air pollution mainly consists of coal smoke with sulfur dioxide and suspended particulate matter. Dozens of studies have been conducted on urban
