"China, which is undergoing rapid economic development and population growth, is facing serious and complicated air pollution problems that have resulted in an unique chemical transformation and transport process. In the past several decades, air pollution in China was caused mainly by the burning of coal as fuel for industrial and domestic purposes; sulfur dioxide(SO2) and particular matter were among the major pollutants. "
National Research Council Urbanization, ENergy, and Air Pollution in China: The Challenges Ahead Proceedings of a Symposium. Washington DC: The National Academies Press, 2004.
"Researchers have made considerably more progress in studying the acute effects of exposures to short-term, high levels of O3 and NO2 than on studying the effects of long-term, low level oxidant exposure at peak levels."
Air Pollution, the Automobile, and Public Health. Washington, DC: The National Academies Press, 1988.
"Physical and chemical measurements of air pollutants provide a precise measure of pollutant exposure which is frequently used to estimate probable biological impacts. In contrast, a biological response to the exposure indicates if the exposure had a biological effect."
Biologic Markers of Air-Pollution Stress and Damage in Forests. Washington, DC: The National Academies Press, 1989.
"The effect of higher densities on VMT is not entirely straightforward, making it difficult to determine the net reduction in automobile use from increased densities."
Driving and the Built Environment: The Effects of Compact Development on Motorized Travel, Energy Use, and co2 Emissions. Washington, DC, 2009.
"More than 131.8 million people in the United States, which equates to 42 percent of the U.S. population, live in counties that have unhealthy levels of either ozone or particle pollution.
Nearly 24.8 million people (8 percent) in the United States live in counties that have unhealthy levels of all three: ozone and short-term and year-round particle pollution. Eighteen cities had lower year-round levels of particle pollution, including 16 cities with their lowest levels recorded. "
