    • Let’s Review Pollution…
    • The Common Air Pollutants
      • Particulates (PM10, PM2.5)
      • Nitric oxide/dioxide
        • – cars, coal.
      • Sulfur dioxide
        • Coal. Causes acid rain; Improving well
      • Ozone
        • usually from NO2; formed mostly on hot summer days
      • Carbon monoxide
        • cars
    • The worst one is: small particles
    • These Are Very Small…
    • Short Movie on Small Particles
      • http:// www.epa.gov/airnow/pm/pm.html
    • It Can Get Bad in Beijing…
    • … But it can be a lot worse, like London in 1952!
    • The Great London Smog of 1952
      • It was a bad combo of cold weather + more coal burning + inversion layer of air…
      • = disaster for 5 days…
        • pollution at 3,000-14,000! (Beijing is usually ~140)
        • 12,000 premature deaths
        • 100,000 illnesses
    • Many People Died From Pollution
    • Australia Dust Storm, 2009
    • Australia Dust Storm, 2009
      • Seven years of low rainfall
      • Particle levels reached 15,400 ug/m3 (a lot higher than in Beijing)
      • What happened? More asthma attacks and Emergency Room visits
    • How Does Pollution Affect Health?
    •  
    • Why Is Pollution Bad?
      • Worse pollution = more disease

        • More doctor visits
        • New babies can weigh less
        • Childhood cancers are higher
        • Asthma can be worse
    • So What About China?
      • Only 1% of China’s cities have safe air
        • (Safe = Particle levels under 40ug/m3)
    • The Main Issues In China
      • Every year in China:
        • ~300,000 premature deaths
        • 20 million cases of lung illness
      • What Are The Main Causes?

        • Factories
        • Indoor cooking/heating with wood and coal

    • Most Polluted Cities in China
    • World Cities & PM10 Levels (2004-5) WHO China US Beijing
    • More About That Graph…
      • Beijing’s PM10, at 150ug/m3, was over 7 times the WHO cutoff of 20
      • Out of 108 China cities monitored by MEP, none met the WHO cutoff
        • Guilin was best in China (29 ug/m3)
        • Beijing 4th worst in China
    •  
    • How Is Pollution Monitored?
    • Beijing City Has Over 20 Monitors
    • Puts Info On Website
    • About That Website…
      • Data is not real time (is the average from the day before, from all stations)
      • So, you don’t know how your neighborhood is right now

    • Schools Should Have Action Plans!
    • School Action Plan: OK Days
    • School Action Plans: Moderate Days
    • Worst Days…
    • In Other Words:

      • Areca Palm   ( 风尾竹 ,  feng (4) wei (3) zhu (2), about RMB 180 each) - 
        • Efficiently converts CO2 to oxygen.
      • Mother-in-Law Tongue   ( 虎皮兰 ,  hu (3) pi (2) lan (2), about RMB 50 each)
        • Efficiently converts CO2 to oxygen at night and is
