Water quality. Fresh water algal growth inhibition test with unicellular green algae included-in-kit Calibration of the testing device1 Scope This International Standard specifies a method for the determination of the growth inhibition of unicellular green algae by substances and mixtures contained in water or by waste water. This method is applicable for substances that are easily soluble in water. With modifications to this method, as specified in ISO 14442 and ISO 5667 16, the inhibitory effects of poorly soluble organic and inorganic materials, volatile compounds, heavy metals
