In fiscal year (FY) 2015, NTP continued to advance toxicology and inform public health policy by providing information about substances in our environment to decision makers and the public. Numerous studies were published on substances of public health concern, such as metals, nanomaterials, and widely used industrial chemicals. NTP improved testing methods and health assessments through collaborations with other federal agencies and international groups, refined methods, prepared a handbook for applying systematic review to environmental health research, and released a handbook of preparation instructions for the Report on Carcinogens. NTP also developed more efficient approaches to predict how chemicals may affect human health through the Tox21 initiative.
On October 2, 2014, the U.S. Department of Health and Human Services Secretary Sylvia Burwell released the 13th Report on Carcinogens, which was prepared by NTP for the secretary. The report lists three new substances as reasonably anticipated to be a human carcinogen, and upgrades the listing of a fourth substance to known to be a human carcinogen. There are a total of 243 substances listed in the report.
In response to a request from the Centers for Disease Control and Prevention (CDC)/Agency for Toxic Substances and Disease Registry, NTP carried out research to evaluate the toxicity of chemicals spilled into the West Virginia Elk River. NTP regularly communicated its findings to the public and other federal agencies via a targeted website. Overall, NTP findings supported the drinking water screening levels established by CDC at the time of the chemical spill.
I invite you to read this report to learn about what we accomplished in FY 2015 to safeguard public health by informing policy with the best science.
