US Tox21 to begin screening 10,000 chemicals

A high-speed robotic screening system, aimed at protecting human health by improving how chemicals are tested in the United States, has begun testing the compounds for potential toxicity.

The compounds cover a wide variety of classifications, and include consumer products, food additives, chemicals found in industrial processes, and human and veterinary drugs. A complete list of the compounds is publicly available by following the link provided.

Testing this 10,000 compound library begins a new phase of an ongoing collaboration between the National Institutes of Health, the U.S. Environmental Protection Agency, and the U.S. Food and Drug Administration, referred to as Tox21. NIH partners include the National Toxicology Program (NTP), administered by the National Institute of Environmental Health Sciences (NIEHS), and the NIH Chemical Genomics Center (NCGC), part of the NIH Center for Translational Therapeutics (NCTT), housed at the National Human Genome Research Institute (NHGRI).

“There has never been a compound library like this before,” said NIEHS/NTP Director Linda Birnbaum, Ph.D.

Birnbaum is especially excited that some of the compounds the NTP has brought forward for testing are mixtures of chemicals. “All of us are exposed to many different chemicals at the same time, not just one chemical at a time,” she said. “These new technologies allow us to more rapidly advance our understanding of not only individual chemicals, but mixtures of chemicals as well.” A subset of the NTP portion of the 10,000 compound library will focus on pilot testing several formulations or mixtures of compounds, a priority area for NIEHS/NTP. The library constituents were selected after a thorough analysis of existing scientific studies, more than 200 public chemical databases, and chemical nominations received from internal and external partners. Each test compound will undergo a thorough chemical analysis to verify its identity and determine its purity, concentration, and stability.
The goal of the testing is to provide results that will be useful for evaluating if these chemicals have the potential to disrupt processes in the human body to an extent that leads to adverse health effects.
The compounds will be tested in the Tox21 robotic screening system at the NCGC in Rockville, Md. The Tox21 robot, unveiled earlier this year, was purchased with funds provided by the NTP as part of its contribution to the Tox21 partnership.
“The robot has undergone rigorous testing since it was installed and unveiled earlier this year. It’s ready to start testing this large compound library,” said NHGRI Director Eric Green, M.D., Ph.D. “This is a milestone for Tox21, because it will allow us to test chemicals at a rate previously impossible for anyone to do by hand.”
