In 2008, the U.S. embassy in Beijing (located in the northeastern part of the city’s downtown area) installed an air quality monitoring device that measures concentrations of airborne particles with diameters of less than 2.5 microns. These tiny particles are the main cause of health problems after long-term exposure, and their monitoring provides a much better appreciation of health risks than the measurement of large (10 microns and above) particles.
