Toxicity of a synthetic chemical, aquatic pollutant (surfactant, sodium dodecyl sulphate, SDS ), to higher plant, aquatic macrophyte Potamogeton was discovered and studied. First paper to report toxicity of the surfactants SDS to aquatic plant Potamogeton. Also, non-lethal concentrations of SDS were found. Information on both toxic and non-toxic concentrations of SDS to aquatic plants has scientific value and practical importance.

MORE INFORMATION:
First paper to report toxic and non-toxic concentrations of the anionic synthetic surfactant, sodium dodecyl sulphate, to an aquatic higher plant species.
Synthetic surfactants are an underestimated class of pollutants that enter aquatic environments. This is the first paper to report the results of experiments on how sodium dodecyl sulphate (SDS) affects aquatic higher plant (macrophyte), Potamogeton crispus. As a result, phytotoxicity to this plant was discovered. Also, concentrations of this chemical that are non-toxic were also established.
**
The new effects of the anionic surfactant sodium dodecyl suplphate on the aquatic macrophyte Potamogeton crispus L. were studied in this paper. Concentrations of 83–133 mg/l caused fragmentation of the stems of plants. The tolerance of the plants to the negative effects of the surfactant was higher in the spring (April) than in the autumn (September).

* Addition to the abstract:
* Macrophytes are important components of ecosystems and participate in the purification of water and support its quality (McCutcheon and Schnoor, 2003; Wetzel, 2001). This is especially important in conditions of pollution of water bodies and water courses. Surfactants constitute a class of pollutants. The ecological danger of surfactants is still insufficiently investigated and analyzed. On the one hand, there are numerous publications on various bioeffects and disturbances of the structure and function of organisms under the action of synthetic surfactants (Davydov et al., 1997; Ostroumov, 2001, 2005, 2006). On the other hand, some authors do not qualify surfactants as major pollutants (Moore and Ramamoorthy, 1984) and believe that, ecologically, they are not highly dangerous for aquatic ecosystems (Fendinger et al., 1994). On the basis of studies of the effect of surfactants and surfactant-containing mixtures and the elucidation and comparison of the tolerance of organisms belonging to different taxa, it was suggested to use angiospermous plants for phytoremediation (Ostroumov, 2001). In this aspect, further investigation and clarification of the facts concerning the interaction of plants and various xenobiotics are necessary. The present paper presents the results of investigations of the effect of various concentrations of aqueous solutions of the anionic surfactant sodium dodecyl sulphate (SDS) on the viability of the aquatic macrophyte pondweed Potamogeton crispus L.
