Toxicological Studies; Request for 
Comments 
summary: On May 10. 198C. the 
Chemical Evaluation Committee (CFC) 
of the National Toxicology Program 
(NTP) met to review eight chemicals 
nominated for toxicology studies and to 
recommend the types of studies to be 
performed, if any. With this notice, the 
NTP solicits public comments on the 
eight chemicals.

SUPPLEMENTARY INFORMATION: As part 
of the chemical selection process of the 
National Toxicology Program, 
nominated chemicals which have been 
reviewed by the NTP Chemical 
Evaluation Committee (CEC) are 
published with request for comment in 
the Federal Register. This is done to 
encourage active participation ir. the 
NTP chemical evaluation process, 
thereby helping the NTP to make mere 
informed decisions as to whether to 
select, defer or reject chemicals for 
toxicology study. Comments and data 
submitted in response to this request are 
reviewed and summarized by NTP 
technical staff, are forwarded to the 
NTP Board of Scientific Counselors for 
use in their evaluation of the nominated 
chemicals, ana then to the NTP 
Executive Committee for decision- 
making. The NTP chemical selection 
process is summarized in the Federal 
Register. April 14. 1981 (46 FR 21828). 
and also in the NTP FY 1987 Annual 
Plan, pages 17-19. 
On May 10. 1988. the CEC met to 
evaluate eight chemicals nominated to 
the NTP for toxicological studies. The 
following table lists the chemicals, their 
Chemical Abstract Service (CAS) 
registry numbers, and the types of 
toxicological studies recommended by 
the CEC at the meeting.

P'ive of the eight chemicals have been 
previously selected for study by the 
NTP. /3-Cudinenc was non-mutagenic in 
Salmonella ar.d in the mouse lumphoma 
assays. It was negative for chromosomal 
aberrations and equivocal for sister 
chromatid exchanges in Chinese 
hamster ovary cells. DiphenylamL-.e and 
Firemaster 680 were non-mutagenic is 
Salmonella. Methacrylonitrile was non- 
mutagenic in Salmonella, and did not 
induce sex-lirked recessive lethal 
mutations in Drosophila. 
Trichloromelamine is on test in 
Salmonella. 
Interested parties are requested to 
submit pertinent information. Tne 
following types of data are of particular 
relevance: 
(1) Modes of production, present 
production levels, and occupational 
exposure potential. 
(2) Uses and resulting exposure levels, 
where known. 
(3) Completed ongoing and/oi 
planned toxicologic testing in the private 
sector including detailed experimental 
protocols and results, in the case of 
completed studies. 
(4) Results of toxicological studies of 
structurally related compounds. 
Please submit all information in 
writing by July 25. 1908. Any 
submissions received after the above 
date will be accepted and utilized where 
possible.
