As shown in Figures 2-5, both PCA and OPLS-DA methods demonstrated that Spirodela
polyrhiza, Landoltia punctata, and Lemna aequinoctialis were clustered together with each other in the score plot.

Toxic effect of arsenic and cadmium alone and in combination on Giant duckweed (Spirodela

Toxicity and genotoxicity tests of the water and bottom sediments were carried out based on the biological tests widely used in the world (EPA 1996a, b; OECD 2003): Spirodela
Floating vegetation included Lemna minor (lesser duckweed), Spirodela
polyrhiza (greater duckweed), Wolffia sp.
