epidemiological study of
childhood asthma in New York City.

Researchers at Instrument Development Lab (IDL), part of DOE’s Environmental Molecular Science Laboratory at Pacific Northwest National Laboratory, are designing lightweight aerosol monitors as part of a long-term study of the possible causes of childhood asthma. For several years, students will carry the monitors, just under 6 inches in length, when they go to school and elsewhere in New York City.  Each monitor includes a pump that continuously draws in air, which then passes through two filters, a global positioning system which provides data about the monitor location, and a triaxial accelerometer which measures the motion the monitor experiences. Scientists at Columbia University and DOE’s Pacific Northwest National Laboratory will analyze the data from the monitors.
