Use of freshwater algae and duckweeds for phytotoxicity testing
10.1002/tox.20042.abs
The toxicity of contaminated water of different origins and chemicals [Cr(III), Pb(II), Cu(II), Cd(II), pyrene] were tested using four test species: the alga Selenastrum capricornutum (new name Raphidocelis subcapitata), the duckweed Lemna minor, and the crustaceans Thamnocephalus platyurus and Daphnia magna. On the basis of the results obtained, the sensitivity of plant species and problems concerning the interpretation of the phytotoxicity data are discussed. The data indicated that the sensitivities of crustaceans and plant species both to individual contaminants and to mixtures are unpredictable and that there is no reason to consider plant species less sensitive than animal species. Lemna minor is more sensitive than Selenastrum capricornutum. With colored samples, duckweed is preferable for toxicity testing. To raise the predictive utility of the phytotoxicity data, it is recommended that natural water be used in the test procedure. © 2004 Wiley Periodicals, Inc. Environ Toxicol 19: 425–428, 2004.
