Nowadays, pollution becomes a common issue. In China, the air pollution is the most prominent and dangerous problem that
influence our study and life. It occurs due to many reasons like excessive burning of fuel for cooking, transportation and other
industrial activities. In physics, the air is not limited to the gas molecules of nitrogen, oxygen, and argon because dry air contains
78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and others are small amounts of gases. The burning of fossil
fuels, additions in the form of carbon dioxide molecules —also known as particle pollutants—have entered the atmosphere as well.
However, they are hurtful to our body and lead to different disease. (1) Therefore, what we should do? How could we protect
ourselves away from pollution?
