National Toxicology Program (NTP); National Institute of
Environmental Health Sciences (NIEHS); Notice of Workshop on Strategies
for Assessing the Implications of Malformed Frogs for Environmental
The Workshops will be held in the Conference Center, Building 101,
South Campus, NIEHS, 111 Alexander Drive, Research Triangle Park, North
Carolina 27709, on December 4-5, 1997, from approximately 8:30 a.m. to
5:00 p.m. on Thursday, December 4th and approximately 8:30 a.m. to 12
noon on Friday, December 5th.
Over the last few years increasing numbers of malformed frogs have
been reported in numerous states, across southern Canada, and in Japan.
Early in 1997 the Minnesota Pollution Control Agency (MPCA) requested
the assistance of the National Institute of Environmental Health
Sciences, National Institutes of Health, and the National Toxicology
Program with their investigation into the cause of the frog
malformations occurring across Minnesota. A research plan has been
implemented to determine whether there is a site-specific correlation
between the malformations and contaminants determined by chemical
analysis of water and sediment, laboratory bioassays, and field
monitoring of frog populations. The causal factors have not yet been
determined. However, evidence to date indicates that pond water and
groundwater from affected sites are capable of producing frog embryo
deformities in the laboratory.
