As science advances, innovations can improve our lives and address significant global challenges, like pollution. However, emerging technologies— such as nanomaterials or new approaches to detect or remove contaminants— can also create novel health hazards for researchers and workers who encounter them. The same is true for emerging contaminants that are not yet well studied. To address these new challenges, the NIEHS Superfund Research Program (SRP) funds Occupational Health and Safety Training Education Programs on Emerging Technologies, known as R25 grants.
