World trade center environmental contaminant database : A publicly available air quality dataset for the New York City area

Environmental data collected in response to the World Trade Center attack on September 11, 2001 and air quality data collected between from 1970 to December 31, 2003 in New York City and New Jersey are now available on the World Wide Web via the World Trade Center Environmental Contaminant Database (1). This database was developed by the Mailman School of Public Health at Columbia University and Bloomberg School of Public Health at John's Hopkins and is intended for use by individuals interested in having access to raw data (i.e., not summary statistics or averaged data) in order to explore the exposures related to the WTC disaster as well as general air quality issues in New York City and New Jersey. This website provides an easily accessible format to tabular data as well as various help files and sampling site maps to facilitate ease of use. Within the next year, the WTCECD should provide links to other (offsite) datasets relevant to WTC exposures, and will incorporate additional datasets provided by researchers at the National Institute of Environmental Health (NIEHS) Centers for Environmental Health.
