Report Substances Selected for Evaluation

Study Scientist
Primary Uses/Exposures Listing Status and Rationale
Antimony Trioxide
Amy Wang
Compound used mainly as a synergist for halogenated flame-retardants in plastics, rubber, and textiles, which are used in a diversity of plastics and other products. It also can be used as a catalyst in polyethylene terephthalate production, as an additive in glass manufacturing and in pigments, or as an additive in paints and ceramics. Concept review: NTP Board of Scientific Counselors Meeting December 2016
Goldenseal Root Powder (Hydrastis canadensis)
Office of Report on Carcinogens staff
Herbal remedy (botanical product) used to treat gastrointestinal disturbances; urinary disorders; hemorrhage; skin, mouth, and eye infections; and inflammation. Concept review: NTP Board of Scientific Counselors Meeting April 2014
Haloacetic Acids Found as Water Disinfection By-Products
Gloria Jahnke 
Includes 13 individual haloacetic acids or a potential class or subclass of these haloacetic acids. People are exposed to these haloacetic acids by ingestion of chlorinated drinking water and by inhalation and dermal contact during bathing or showering or when using swimming pools and spas that use chlorine for disinfection. Peer review of draft monograph: July 2017
Helicobacter pylori (H. pylori): Chronic Infection
Ruth Lunn 
Gram-negative, multiflagellated bacterium that colonizes the stomach and causes peptic ulcer. Bacterium is spread by person-to-person contact, especially among family members. Routes of exposure include oral-oral, fecal-oral, and iatrogenic; exposure from contaminated water is also possible. Risks factors for infection include age, race, socioeconomic status such as crowded living conditions, and poor sanitation/hygiene. Concept review: NTP Board of Scientific Counselors Meeting April 2016
Shift Work at Night, Light at Night, and Circadian Disruption
Ruth Lunn
Unnatural (e.g., ill-timed) electrical light, especially light at night, may disrupt sleep and biological processes controlled by endogenous circadian clocks. People, who by virtue of the nature of their work, lifestyle choices, or residence, are subjected to exposure to unnatural light. Shift workers who work at night can experience an extreme type of exposure to light at night and changes in other activities, such as changes in daily activities, eating, sleeping, lifestyle factors, and social behavior. Workshop: Shift Work at Night, Artificial Light at Night, and Circadian Disruption workshop
