Industry:Biology; Chemistry
Map showing the positions in the genome of genes or other genetic markers, either relative to each other or as a physical map of absolute distances.
Industry:Biology; Chemistry
Maximal stimulatory effect induced by a compound in relation to that of a given reference compound.
Industry:Biology; Chemistry
Maximum amount of a pollutant released from a given source to a specified medium which is acceptable under specified circumstances.
Industry:Biology; Chemistry
Maximum concentration or intensity of exposure that can be tolerated without significant effect (based on only scientific and not economic evidence concerning exposure levels and associated health effects).
Industry:Biology; Chemistry
Maximum dose (of a substance) that produces no detectable changes under defined conditions of exposure.
Note: This term tends to be substituted by no-observed-adverse-effect level (NOAEL) or no-observed-effect level (NOEL).
Industry:Biology; Chemistry
Maximum dose of a substance at which no specified response is observed in a defined population and under defined conditions of exposure.
Industry:Biology; Chemistry
Measure of the frequency at which new events occur in a population.
Note: This is the value obtained by dividing the number of new events that occur in a defined period by the population at risk of experiencing the event during this period, sometimes expressed as person-time.
Industry:Biology; Chemistry
Measured or calculated amount or mass concentration of a substance to which an organism is likely to be exposed, considering exposure by all sources and routes.
