HazDat Database
ATSDR's Hazardous Substance Release and Health Effects Database
HazDat, the Agency for Toxic Substances and Disease Registry's
Hazardous Substance Release/Health Effects Database, is
the scientific and administrative database developed to provide
access to information on the release of hazardous substances
from Superfund sites or from emergency events and on the
effects of hazardous substances on the health of human
populations. The following information is included in HazDat: site characteristics, activities and site events, contaminants
found, contaminant media and maximum concentration levels,
impact on population, community health concerns, ATSDR public
health threat categorization, ATSDR recommendations,
environmental fate of hazardous substances, exposure routes,
and physical hazards at the site/event. In addition, HazDat
contains substance-specific information such as the ATSDR
Priority List of Hazardous Substances, health effects by route
and duration of exposure, metabolites, interactions of
substances, susceptible populations, and biomarkers of exposure
and effects. HazDat also contains data from the U.S.
Environmental Protection Agency (EPA) Comprehensive
Environmental Response, Compensation, and Liability Information
System (CERCLIS) database, including site CERCLIS number, site
description, latitude/longitude, operable units, and additional
site information.
Internet HazDat may be queried directly from a World-Wide Web Browser with Forms support by clicking on any one of the database queries listed below. This method of access to our relational database was made possible by GSQL, a simple forms interface to SQL databases, developed at the National Center for Supercomputing Applications (NCSA). More information on GSQL may be found in NCSA's Tutorial on GSQL.

Internet HazDat data fields (or columns) are defined in the Internet HazDat Data Dictionary.
ATSDR has conducted public health assessments at more than 1,450 sites, developed toxicological profiles for more than 150 hazardous substances, performed more than 5,000 health consultations, and conducted or funded more than 150 health studies.
These activities have resulted in the publication of
many Agency documents. Important information from these source
documents has been abstracted into the Agency's HazDat database, and new information is added on a continuous basis. The information provided in Internet HazDat will be expanded and updated at regular intervals.
HazDat contains data from the U.S. Environmental Protection Agency's CERCLIS database including site CERCLIS number, site
description, latitude/longitude, operable units, and additional
site information. This information allows the cross-referencing of hazardous waste sites with EPA databases.
Additional environmental,
socioeconomic, earth science, and global change datasets may be
located through CIESIN's SEDAC Data and Information Catalog Services.
For datasets specifically
relevant to Federal Facilities Public Health Assessments see the
CIESIN Information Network ATSDR Node.
