Air Quality China

PM 2.5 Levels Across China

Air Quality Index

Sources of China’s Air Pollution Factories Burning Coal to produce electricity Blowing dust

Map of where the coal fired power plants are in China

What is PM2.5?

Health Effects of PM 10 and PM 2.5 pollution PM 2.5 is more dangerous because it is more toxic and travels deeper into the body (is often absorbed by the blood). Have been linked to lung and other cancers

What is pm10 vs. pm2.5? Coarse Particles (PM 10 )Fine Particles (PM 2.5 ) What they are smoke, dirt and dust from factories, farming, and roads mold, spores, and pollen toxic organic compounds heavy metals How they’re made Crushing and grinding rocks and soil then blown by wind Driving automobiles Burning plants (brush fires and forest fires or yard waste) Smelting (purifying) and processing metals Coal fired power plants pm = particulate matter
