This finding suggested that BPA and BPAF exposure adversely affected the ovary at doses lower and higher than the LOAEL, which could indirectly have a negative impact on endometriosis.
This uncertainty increases with the spacing between the NOAEL and the LOAEL, and thus the dose spacing of the study.
OTC: LOAEL, EC values and confidence interval (CI) from ecotoxicity tests.

But the data suggested that in only half of the cases could the variability in hair mercury be accounted for by the amount of mercury estimated in the fish the women consumed: Even among some of the women whose fish intake fell within the FDA/EPA recommendations for pregnant women, levels exceeded 0.3 mcg/g, which in the previous study, was assigned as the LOAEL.
2) La dosis de referencia fue calculada utilizando lineamientos muy conservadores de la EPA para estimar el nivel para el que no se observan efectos adversos (NOAEL) a partir del nivel experimental en el que se observa algun efecto adverso minimo (LOAEL).
Wherever possible, we'd start with a No Observed Adverse Effect Level, or LOAEL. If you know that people took X amount--say 100 milligrams--and there was no toxicity in any individuals, that would be a LOAEL.
In the article, in which he reviews the scientific evidence that shows the nutrients and intake levels that help prevent disease, Hathcock explains why the safety of nutrients at specific intake levels can be established only by a direct approach based on credible scientific data - the no observed adverse effect level (NOAEL) or the lowest observed adverse effect level (LOAEL).
For the 143 pollutants, the maximum and median concentrations monitored during a 24-hour period or the average modeled annual concentrations, as applicable, were compared to the lowest-observed-adverse-effect-level (LOAEL) and to the health reference level.(*)
The BPA dose range was based on a low observed adverse effect level (LOAEL) of 50 mg BPA/kg, a no observed adverse effect level (NOAEL) of 5 mg/kg for BPA, and the reference dose currently set by the U.S.

Alternatively, in the absence of a NOAEL, it may be necessary to use the dose at which a significant adverse effect is first observed, or the lowest-observed-adverse-effect level (LOAEL).
