title: Acclimation to lead in the freshwater isopod Asellus aquaticus.
abstract: Some populations of the isopod Asellus aquaticus from polluted rivers are tolerant to lead. Here it is shown that nontolerant animals from an unpolluted site can be made tolerant by laboratory exposure to low levels of the metal, and it is suggested that naturally occurring tolerance may be achieved by acclimation.
