In the presence of this aquatic, submerged, free-floating higher plant (rigid hornwort) in water system, it was discovered that a decrease in concentrations of the four heavy metals (cadmium; copper; lead; zinc; Cu, Zn, Cd, and Pb) in the water medium accelerated. The aquatic macrophytes served as a factor to speed up the water purification (decontamination) process in the aquatic system. The method for measuring the heavy metals was stripping voltammetry.

https://www.researchgate.net/publication/216175249; The goal of this study was to test whether the surfactant SDS has an inhibitory effect on the ability of the planktonic filter-feeder Daphnia magna to remove phytoplankton from water during their filtration activity. Daphnia were kept under laboratory conditions in vessels and fed with phytoplankton: the green algae Scenedesmus quadricauda (Turp.) Breb. After filtration for 6–24 h in the presence of SDS at concentrations 5 and 10 mg/l, the abundance of S. quadricauda cells in water was higher than in the control. At the lower SDS concentrations (0.1, 0.5, and 1 mg/l), differences in the abundance of algal cells relative to the control were observed after 3 h of incubation and disappeared after 6–24 h of incubation. The calculation of the mean rate of algae removal by daphnia showed that this parameter decreased within the first 3 h after the beginning of incubation in the presence of SDS.- A fragment of the text of the article:Many species of planktonic and benthic invertebrates are active filter-feeders. The filtration activity of aquatic organisms is of great importance for the functioning of ecosystems [1‐3]. It was shown earlier that surfactant sodium dodecylsulfate (SDS) inhibits the filtration activity of Mytilus edulis, M. galloprovincialis , and some other aquatic filter-feeders [4‐15], which is manifested in a decreased removal of ...

00032 Ispani mires - the sound of frogs on unidentified potamogeton natans PelophylaxPublished: 2011/07/12Channel: MarcelInGeorgie- Effects of three surfactants on the filtration rates by marine mussels were studied. The xenobiotics tested represented anionic, cationic and non-ionic surfactants (tetradecyltrimethylammonium bromide, a representative of a class of cationic surfactants; sodium dodecyl sulphate, a representative of anionic alkyl sulfates; and Triton X-100, a representative of non-ionic hydroxyethylated alkyl phenols). All three surfactants inhibited the clearance ...

- Suspension-feeders are found in both pelagic and benthic systems. They function as an important part of an ecosystem's biomachinery that maintains water quality in aquatic systems. They remove suspended matter and excrete faeces, pseudofaeces and dissolved inorganic materials that contribute to nutrient cycling between the water column and the benthic habitats. Suspension-feeders are a key part of ...
