Notes
The utilization of algae as bioassay organisms is now commonly accepted. This type of research has primarily considered the response of algae to nutrients. The research sponsored by the Environmental Protection Agency (EPA) on algal assay procedures certainly gave added emphasis to the nutrient research program. The response of algae to toxic materials has also been investigated. These studies involved both photosynthetic and growth inhibition studies. The algal toxicity studies have covered a wide range of toxic materials but the heavy metals seem to have been studied as much or more than other materials. Most of the work to date with heavy metals has been with single ions except for the work of Hutchinson, who considered the synergistic interactions of a number of metal ions. The purpose of this study was to determine the effect of ionic zinc, sulfide, and ionic zinc plus sulfide on the oxygen evolution of Selenastrum capricornutum.
