Abstract

Euglena gracilis was exposed for 24 hr to concentrations of copper, nickel, lead and zinc ranging from 0.1 to 2.0 mg L-1 and to pentachlorophenol ranging from 0.1 to 10.0 mg L-1. Photosynthetic efficiency (PE) was inhibited by increasing concentrations of the heavy metals. Nickel was found to be the least toxic of the metals to E. gracilis, while the other three metals exhibited similar levels of toxicity. Treatment with pentachlorophenol causedunusual responses of the photosynthetic apparatus probably due to the especially high toxicity of this substance. Both cell shape and motility turnedout to be insensitive physiological parameters for the toxicity testing ofthe substances studied.
