DEPARTMENT OF HEALTH AND HUMAN SERVICES
National Toxicology Program (NTP) Board of Scientific Counselors'
Meetings; Announcement of NTP Draft Technical Reports Projected for
Public Review From June 1994 Through Fall 1995
To earlier inform the public and allow interested parties to
comment or obtain information on long-term toxicology and
carcinogenesis studies prior to public peer review, the National
Toxicology Program (NTP) again publishes in the Federal Register a
current listing of draft Technical Reports projected for evaluation by
the NTP Board of Scientific Counselors' Technical Reports Review
Subcommittee during their next four meetings from June 1994 through the
fall of 1995. We plan to continue updating the listing with
announcements in the Federal Register once or twice a year. The next
meeting dates are June 21-22, 1994 and November 29-30, 1994. Specific
dates for 1995 meetings will be established at a later time.
The attached table 1 lists draft Technical Reports for long-term
studies on chemicals within known or approximate dates of reviews and
includes Chemical Abstracts Service (CAS) registry numbers, primary
use, route of administration, species, exposure levels, and NTP report
numbers (if assigned).
Technical Reports of short-time toxicity studies are currently
reviewed by mail; however, when necessary may be reviewed in open
meetings. The attached Table 2 lists the draft Technical Reports of
short-term toxicity studies tentatively projected for review by mail
during 1994 and also includes Chemical Abstracts Service (CAS) registry
numbers, primary use, route of administration, species, exposure
levels, and NTP report numbers (if assigned).
Those interested in having more information about any of the
studies listed in this announcement, should contact Central Data
Management as early as possible by telephone or by mail to: MD-A0-01,
NIEHS, P.O. Box 12233, Research Triangle Park (RTP), North Carolina
27709 (919-541-3419). The program would welcome receiving toxicology
and carcinogenesis data from completed, ongoing or planned studies by
others as well as current production data, human exposure information,
and use and use patterns.
The Executive Secretary, Dr. Larry G. Hart, P.O. Box 12233,
Research Triangle Park, North Carolina 27709, telephone 919/541-3971,
will furnish final agendas and other program information prior to a
meeting, and summary minutes subsequent to a meeting.
