LOEL stands for which term?

Explanation:
LOEL stands for the Lowest Observed Effect Level. This is the smallest exposure level at which a measurable effect is observed in a study. The effect can be any detectable change, not necessarily harmful. It sits in contrast to the lowest dose that causes an adverse effect (LOAEL), and to NOEL/NOAEL, which denote levels where no effects are observed. The term “Recommended Exposure Level” isn’t a standard toxicology term. So the correct interpretation is that LOEL is the Lowest Observed Effect Level.
