Abstract
Steelhead trout (Salmo gairdneri) were continuously or intermittently exposed to copper over a 78-d period from 6 d postfertilization through 5 wk postswimup. Copper was introduced into the intermittent exposure chambers for 4.5 h each day. Continuously exposed fish survived and grew better than intermittently exposed fish at the same daily mean copper concentrations. Intermittently exposed fish accumulated significantly more copper than those continuously exposed at the same daily mean concentrations. Results demonstrated that data derived from continuous laboratory exposures should not be directly converted to water quality criteria where toxicant concentrations in natural waters are temporally variable.
