What Does NEL Stand For?

NEL stands for No Effect Level

NEL, or No Effect Level, refers to the highest dose or concentration of a substance in a study at which no significant adverse effects are observed in the test subjects. This measure is crucial in toxicology and risk assessment, helping to establish safe exposure limits for chemicals, pharmaceuticals, and environmental contaminants. By identifying the NEL, researchers can better assess the potential risks associated with exposure and inform regulatory guidelines.
