Toxicity Testing in the 21st Century (Tox21)

Toxicity Testing in the 21st Century (Tox21) is an innovative approach to evaluating the safety of chemicals and substances. Using advanced technologies like cell-based assays and computer models, it rapidly screens hundreds of thousands of compounds for potential health risks without relying on traditional animal testing. Tox21 aims to identify harmful effects early, reduce animal use, and improve the accuracy and speed of safety assessments. This approach helps federal agencies, researchers, and manufacturers make informed decisions to protect public health and the environment more efficiently.
