…SeqAPASS provides us with a fast, efficient screening tool. Using it, we can begin to extrapolate toxicity information from a few model organisms (like mice, rats, zebrafish, etc.) to thousands of other non-target species to evaluate potential chemical susceptibility.
SeqAPASS provides an example of how EPA Chemical Safety for Sustainability researchers are leading the effort to usher in a new generation of toxicology practices that aspire to reduce the number of animals used, decrease costs, and increase the efficiency of chemical toxicity testing. The 21st century chemical toxicity testing strategy incorporates these ideals and has given rise to adverse outcome pathway (AOP) development and rapid, high-throughput chemical screening programs such as EPA’s ToxCast program.
