Water quality - Determination of the growth inhibition effects of waste waters, natural waters and chemicals on the duckweed Spirodela polyrhiza - Method using a stock culture independent microbiotest

ISO 20227:2017 specifies a method for the determination of the inhibition of the growth of the first fronds of Spirodela polyrhiza germinated from turions, by substances and mixtures contained in water or waste water, including treated municipal waste water and industrial effluents. The test is also applicable to pure chemicals and in particular, plant protection products and pesticides.
