Summary
Ankistrodesmus braunii was used as the test organism to assess the effects of mercuric chloride on the growth of this species. Optical density measurements correlated highly with dry weight determinations, chlorophyll content, total cell counts, and respiring cell counts. Any one of the above methods may be used alone or in combination with other methods to assess the effects of toxicants on algal growth and survival.
