The measurement of alkaline phosphatase activity (APA) of target phytoplankton is a recently developed bioassay that has been used to determine the algicidal effects of polyphenols from Eurasian watermilfoil (Myriophyllum spicatum) [80]. Phytoplankton produce extracellular enzymes, such as alkaline phosphatase, to provide additional sources of nutrients. Fluorescence spectrometry is used to measure APA, with methylumbeliferyl-phosphate used as substrate and mixed with the algal or cyanobacterial suspension and the suspected inhibitor. 

The masses of vegetation produced by weed species such as elodea (Elodea canadensis Michx.), coontail (Ceratophyllum demersum L.), and Eurasian watermilfoil Myriophyllum spicatum L.) remove herbicide residues from water (14). Najas sp. and Potamogeton sp. in plastic pools...
