## Background Information on the NTP Board of Scientific Counselors

The BSC is a technical advisory body comprised of scientists from the public and private sectors who provide primary scientific oversight to the NTP. Specifically, the BSC advises the NTP on matters of scientific program content, both present and future, and conducts periodic review of the program for the purposes of determining and advising on the scientific merit of its activities and their overall scientific quality. The TRR Subcommittee is a standing subcommittee of the BSC. BSC members are selected from recognized authorities knowledgeable in fields such as toxicology, pharmacology, pathology, biochemistry, epidemiology, risk assessment, carcinogenesis, mutagenesis, molecular biology, behavioral toxicology and neurotoxicology, immunotoxicology, reproductive toxicology or teratology, and biostatistics. Its members are invited to serve overlapping terms of up to four years. BSC and TRR Subcommittee meetings are held annually or biannually.

    - TR 566 Diethylamine (CASRN 109-89-7)

                    ○ Used mainly as a chemical intermediate to produce the corrosion inhibitor,                      *N,N*                    -diethylethanolamine, and to lesser extent to produce pesticides, insect  repellants, pharmaceuticals, and rubber processing chemicals.                
    - TR 567 Ginseng (CASRN 50647-08-0)

○ Ginseng is a perennial aromatic herb widely used in herbal remedies for enhancing stamina and endurance for mental and physical performance.
