DefinitionThis section has been translated automatically.
NOEL (NOEC) is the acronym for "No Observed Effect Level". NOEL is defined as the highest dose (exposure concentration) at which no significant effects (no deviations from the biological norm) were observed. It is the maximum ineffective dose. NOEL (NOEC) values are determined from longer-term test procedures.
