From The Cornell Chronicle - July 23, 2009Improved air quality during Beijing Olympics could inform pollution-curbing policies
The same view of NW Beijing superimposed post vs. pre efforts.
The air in Beijing during the 2008 Olympics was cleaner than the previous year's, due to aggressive efforts by the Chinese government to curtail traffic, increase emissions standards and halt construction in preparation for the games, according to a Cornell study.
Led by Max Zhang, assistant professor of mechanical and aerospace engineering, the study indicates that such measures as regulating traffic density and encouraging public transportation can have a significant impact on local air quality.
"We hope our study can help or advise local regulators and policymakers to adopt long-term sustainable emission controls to improve air quality," Zhang said. "That's our mission."

The Scientist: Thomas Midgley, Jr.
Thomas Midgely, Jr.
There is a limited number of people for whom contracting polio could be morbidly viewed as a good thing. But according to British comedian Phil Jupitus, when “the human being in history who has done the most damage to the environment” contracted a chronic disease, the world was better off for it.
This menace was Thomas Midgley Jr., class of 1911 — one Cornell alumnus seldom bragged about during tours of Sibley School of Mechanical and Aerospace Engineering. . . . Midgley’s inventions, the tetra-ethyl lead (TEL) additive in gasoline and chlorofluorocarbon (CFC) refrigerants, became two of the most talked about chemical pollutants in human history.
CFCs were a .... miraculous discovery. Refrigerants at the time were harmful in their own right. A refrigerant leak in a Cleveland hospital in 1929 killed over 100 people. “To put this in historical perspective,” Prof. Ke Zhang, mechanical engineering said, “Before CFCs, the coolants [were] toxic gases, like SO2 and ammonia.

I-81 & Air Quality: A Research Project
“The transportation on I-81, such as mobiles and trucks, has an impact on the air pollution,” said K. Max Zhang, assistant professor of mechanical and aerospace engineering at Cornell University and one of the leading researchers in the project.

Study to test quality of air in Syracuse
Hopke, Mitchell and the other researchers - Thomas Holsen, of Clarkson, and Max Zhang, of Cornell University - won a $600,000 research grant last year from the Center of Excellence. In addition, they acquired some of the air-monitoring equipment with $380,000 from the New York State Foundation for Science, Technology and Innovation.

A Sunny Neighborhood
Residents of the Palamanui eco-community will have it all—as if a breezy spot in the hills near Kona, Hawaii, weren’t enough. The 725-acre residential complex, slated to open in 2010, will boast a health club, a university, even a forest preserve.

Professor Charts Air Quality Before And After Beijing Olympic Games
Graduate student Xing Wang monitors computer equipment that measures air quality in Beijing in August 2007.
The Lost Dog Café’s upstairs lounge played host to the Ithaca Science Cabaret speaker series last night as Ithaca residents and science enthusiasts alike crowded into the dimly lit lounge. They reclined on the couches and perched themselves on the chairs while sipping wine and listening to this month’s speaker. Prof. Max Zhang, mechanical and aerospace Engineering at Cornell, explored the scientific basis for concern about air quality in Beijing during this past summer’s Olympic Games.
Zhang’s discussion, entitled “2008 Olympics: Beijing Air Quality Demystified,” examined one of the biggest issues leading up to the 2008 Summer Olympics: air quality in Beijing. According to The New York Times, many American competitors, elected to forgo the outdoor opening ceremonies because they felt the extended exposure to Beijing’s smog-filled air would be detrimental to their performances. According to Zhang, the Chinese government and Beijing officials took measures to try and curb the amount of pollution in Beijing before the Olympics. They imposed traffic regulations in order to try and limit emissions from vehicles, especially trucks that were even banned from driving in the streets of Beijing during the Olympics. They created new subway lines and tried to encourage people to take public transportation by heavily subsidizing it and charging passengers about 25 cents in American currency to travel. All construction was postponed until after the Olympics to limit pollution.

The Stranglehold of Weather on Beijing's Air Quality
When the Opening Ceremonies launch the XXIX Olympiad in Beijing on Friday, city officials will no doubt hope their efforts pay off to reduce the city's usual pall of smog and bring blue skies to the games. But their policies may matter little in the face of the region's weather — the main influence on Beijing's pollution levels, according to one scientist.

Meeting to consider tree planting as antidote to urban ills is uprooted by 'inconvenient conclusion'
"I think that I shall never see/A poem lovely as a tree," wrote Joyce Kilmer. The poet, no doubt, was talking about aesthetics. If he wrote those lines today, chances are he would also have urban blight and community health in mind.

The world’s first purpose-designed-and-built ultrafine particle monitoring system, the TSI Model 3031 Ultrafine Particle (UFP) Monitor provides a continuous record of number concentration and particle size of potentially toxic ultrafine particles before and during the Olympic Games. The monitoring is supervised by researchers from Cornell and Peking Universities. These researchers are conducting a four year long collaborative air pollution study, started in 2006, that aims to understand the long term health effects of ultrafine particles especially on children and the elderly in Beijing.
