Table 6 illustrates the acute toxicity of PFOS to fish, invertebrates, and algae. The data indicate that PFOS is practically nontoxic to freshwater algae and aquatic vascular plants, that is, Lemna gibba.PFOS exhibits only slight toxicity to invertebrates and is considered ‘of moderate concern’ to fish according to the USEPA TSCA criteria.



studied and two species (Lemna minor and L. gibba) proved to be most effective in managing nutrients (Kömer and Vermaat, 1998; Vermaat and Hanif, 1998). Of the two, L. minor is the most common species found in Florida (Long and Lakela, 1976), and may pose a nuisance because of its excessive growth.

Lemnaceae - Images of Lemna turionifera


Three species of duckweeds viewed with backlighting: A. Lemna minuta with a single vein and small size (1-2 mm long); B. L. turionifera with three veins, dorsal row of papules and reddish anthocyanin on lower side. This species may be confused with nongibbous L. gibba, but that species generally lacks the dorsal row of papules and often develops anthocyanin on its upper side; C. Landoltia ...
