We divide the NOAEL or LOAEL by the uncertainty factor.
Analysis of 204 monographs of Polish occupational exposure limits prepared in 2002 to 2013 shows that for the 169 substances, the proposed value of the maximum admissible concentration is based on the LOAEL or NOAEL published in the literature (Table 1 and 2).
Several studies during the last two decades provide for the determination of Lowest Observed Adverse Effect Levels (LOAELs) or No Observed Adverse Effect Levels (NOAELs) for neurological effects in workers exposed to Mn in settings such as smelters, dry alkaline battery manufacturing facilities, and ferromanganese alloy production plants (33,34,52,62,82,88,99,107-114).
Of note is that if the POD was a LOAEL, there were two adjustments-one based on how much lower the NOAEL might be, and a second one based on what the BMD might be for a given NOAEL.

D--max 3--extrapolation from the lowest-observed-adverse effect level (LOAEL) to NOAEL,
Methodological differences related to the use of benchmark dose rather than the lowest observed adverse effect level (LOAEL), the study of small-sized populations or analytical aspects such an insufficient adjustment for variations in diuresis, might account for part of the variation in these estimates.
The Agency for Toxic Substances & Disease Registry (ATSDR) determined the lowest-observed adverse-effect level (LOAEL) for intermediate-duration exposure (15-364 d) of DBT in rodents as 5 mg/kg/day (ATSDR 2005).
