(exposure-response function, ERF): Relationship between the exposure of a given organism, system, or (sub)population to an agent in a specific pattern during a given time and the magnitude of a continuously graded effect to that organism, system, or (sub)population.


This term has several related terms that may have slightly different meaning. Effect and response are interchangeable words. Also the word function is used instead of relationship.
Concentration-effect relationship
Relationship between the exposure, expressed in concentration, of a given organism, system, or (sub)population to an agent in a specific pattern during a given time and the magnitude of a continuously graded effect to that organism, system, or (sub)population. The concentration is measured at a defined site. [1].


Dose-response relationship
Relationship between the amount of an agent administered to, taken up by, or absorbed by an organism, system, or (sub)population and the change developed in that organism, system, or (sub)population in reaction to the agent.[2]<section end=glossary />
