[ATSDR-202]
Availability of a Guidance Manual for the Assessment of Joint
Toxic Action of Chemical Mixtures and Nine Interaction Profiles CD-ROM
[Final Documents] and Two Interaction Profiles [Drafts for Public
Comments]
AGENCY: Agency for Toxic Substances and Disease Registry (ATSDR),
Department of Health and Human Services (DHHS).
ACTION: Notice of availability.
-----------------------------------------------------------------------
SUMMARY: This notice announces the availability of the Guidance Manual
for the Assessment of Joint Toxic Action of Chemical Mixtures and nine
interaction profiles CD-ROM prepared by ATSDR [final documents]. This
notice also announces two additional interaction profiles that will be
released as drafts for public comments.
DATES: The Guidance Manual and nine interaction profiles were included
on the ATSDR ToxProfiles 2004 TM including ToxFAQs
TM CD-ROM released in October 2004. The two additional
interaction profiles [drafts for public comments] will be available on
January 1, 2005. The comment period for the two additional profiles
will be from January 1, 2005 to March 31, 2005.
ADDRESSES: Written requests for the CD-ROM should be sent to the
attention of Ms. Yulandia Jordan, Office of Communication, Agency for
Toxic Substances and Disease Registry, Mailstop E-29, 1600 Clifton
Road, NE., Atlanta, Georgia 30333 or by e-mail to [email protected].
Requests for the guidance manual and/or interaction profiles must
be in writing and submitted to the address mentioned above. ATSDR
reserves the right to provide only one copy free of charge.
In case of extended distribution delays, requesters will be
notified.
The documents will be also available on ATSDR's Web site at http://www.atsdr.cdc.gov.
FOR FURTHER INFORMATION CONTACT: Please send comments or questions
regarding information contained in the profiles to Dr. Hana Pohl,
Division of Toxicology, Agency for Toxic Substances and Disease
Registry, Mailstop F-32, 1600 Clifton Road, NE., Atlanta, Georgia
30333, telephone (888) 422-8737.
SUPPLEMENTARY INFORMATION: Six of the interaction profiles were
developed by ATSDR for hazardous substances at the National Priority
List (NPL) sites and three interaction profiles were developed by ATSDR
for the hazardous substances at the Department of Energy (DOE) and
National Aeronautics and Space Administration (NASA) waste sites under
Section 104(i)(3) and (5) of the Comprehensive Environmental Response,
Compensation, and Liability Act of 1980 (CERCLA). This public law
mandates that ATSDR shall assess whether adequate information on health
effects is available for the priority hazardous substances. Where such
information is not available or under development, ATSDR shall, in
cooperation with the National Toxicology Program, initiate a program of
research to determine these health effects. The Act further directs
that where feasible, ATSDR shall develop methods to determine the
health effects
[[Page 76769]]
of substances in combination with other substances with which they are
commonly found. The Food Quality Protection Act (FQPA) of 1996 requires
that factors to be considered in establishing, modifying, or revoking
tolerances for pesticide chemical residues shall include the available
information concerning the cumulative effects of substances that have a
common mechanism of toxicity, and combined exposure levels to the
substance and other related substances. The FQPA requires that the
Administrator of the Environmental Protection Agency consult with the
Secretary of the Department of Health and Human Services (which
includes ATSDR) in implementing some of the provisions of the act.
To carry out these legislative mandates, ATSDR has developed a
chemical mixtures program. As part of the mixtures program, ATSDR
developed a guidance manual that outlines the latest methods for
mixtures health assessment. In addition, a series of documents called
interaction profiles are being developed for certain priority mixtures
that are of special concern to ATSDR. The purpose of an interaction
profile is to evaluate data on the toxicology of the ``whole'' priority
mixture (if available) and on the joint toxic action of the chemicals
in the mixture in order to recommend approaches for the exposure-based
assessment of the potential hazard to public health.
All the documents were submitted to both the peer-review and the
public review processes. Changes in the documents reflect those
addressing reviewers' comments.
The following documents were made available to the public in
October 2004.

Guidance manual for the assessment of joint toxic action of
