Shanghai’s Environment

The air quality-monitoring network measures the number of Fine Particles (PM2.5) in the air. PM2.5 are really small particles that are less than 2.5 microns in diameter, and these air pollutants are really dangerous if an individual takes in a lot because they can penetrate the lungs and enter your bloodstream. Cars, power plants, sea spray, and many other factors contribute to the fine particle count. The average air quality index in Shanghai in 2016 was 45 micrograms per cubic meter (um/m3). On the universal scale that measures air quality level, 45 um/m3 still falls under the “Good” category. The average number does fluctuate, and I’ve personally seen the city fall under the “Unhealthy” air pollution level at 205 um/m3. I find it really difficult to have days where you can’t walk outside due to the overexposure of these particles.

How have people been adapting to this environment?:

People have adapted by using more environmentally conscious forms of transportation. Car exhaust creates PM2.5; many people have decided to use public transportation or biking as a means of getting around. If you’ve ever seen someone wearing a surgical mask in public, they probably aren’t terminally ill. The masks help prevent their wearers from taking in all of the harmful particles.
