In a … hour acute toxicity study, the cultures of {class, species, strain} were exposed to {test material} at {nominal/measured} concentrations of {0, x1, x2, …xn mg a.i./L} under static or renewal conditions in accordance with the ….. {specify the guideline followed}.  The NOEC or EC05 and EC50/IC50 values based on cell density {or other endpoints} were …. and …. Mg a.i./L, respectively.  The % growth inhibition in the treated algal culture as compared to the control ranged from … to … .

 

The following abnormalities were noted:  (list abnormalities that may include unusual cell shape, colour differences, flocculation, adherence of algae to test vessels, aggregation of algal cell, precipitation in the test solution, or stimulation).  [If toxicity and abnormalities were not observed, state “There were no compound related phytotoxic effects.”]

 

This toxicity study is classified as [enter acceptability classification e.g. acceptable/ unacceptable/ supplementary) and {satisfies/does not satisfy} the guideline requirements for {indicate study type and species} toxicity study.
