V. Ugrekhelidze et V. Phiriashvili, Uptake and transformation of some water phenolic pollutants by common duckweed (Lemna minor L.), FR ENV BULL, 9(7-8), 2000, pp. 483-488
Common duckweed (Lemna minor L.) plants absorb and utilize U C-14-phenol, U
C-14-o-nitrophenol, or U C-14-hydroquinone. The uptake consists of an init
ial absorption phase that is complete after the first hour, followed by a s
lower, constant uptake phase. All three phenols penetrate into the cell pre
dominantly as non-dissociated molecules. The most part of absorbed phenolic
compound binds with low-molecular weight peptides and proteins, and la sma
ll part is transformed via cleavage of an aromatic ring.
