Explanation of methodology (some details on the choice of the biological species and chemicals to study). Why the great pond snail and freshwater mussels were studied in this reseach project: they are among the most common benthic species of invertebrates in water habitats of Eurasia. Their biomass is one of the biggest, or just the biggest, among aquatic invertebrates in Eurasia and other parts of the world. Why the plant species, Nuphar lutea (Yellow Water-lily) , was used in this research project: it is one of the most common aquatic plant species in the freshwater habitats of Eurasia. Why the plant species, Taraxacum officinale, was used in this research project: it is a common laboratory practice to feed the great pond snail with leaves of this higher plant. Why the synthetic surfactants ТDТМА (tetradecyltrimethylammonium bromide) and SDS (sodium dodecyl sulfate) were used: they are representatives of the two major classes of synthetic surfactants, namely, cationic surfactants, and anionic surfactants. These two chemicals were studied in many other publications of Dr. Sergei Ostroumov, so that lots of data to compare toxic effects of these chemicals on organisms are available. A detailed explanation of methodology was also published in the book Biological Effects of Surfactants (Ostroumov, 2005, https://www.researchgate.net/publication/200637626)

Comment on the biological species that were studied in this paper: the great pond snail is a species of large air-breathing freshwater snail, an aquatic pulmonate gastropod mollusk in the family Lymnaeidae. Range Description: A widespread species distributed in Asia (central, north and south and southeast), north America, north Africa and New Zealand. The great pond snail has a shiny yellowish brown shell.
Nuphar lutea (Yellow Water-lily) is an aquatic plant of the family Nymphaeaceae, native to temperate regions of Europe, northwest Africa, and western Asia.
Unio is a genus of medium-sized freshwater mussels, aquatic bivalve mollusks in the family Unionidae, the river mussels. Unio is the type genus of the family Unionidae. About this family: The range of distribution for this family is world-wide. It is at its most diverse in North America, with about 297 recognised taxa, but China and Southeast Asia also support very diverse faunas. Freshwater mussels occupy a wide range of habitats, but most often occupy lotic waters, i.e. flowing water such as rivers, streams and creeks.

Explanation of terminology: pellets are the particles of the undigested organic matter (mainly biomass of undigested food) that the aquatic mollusks (snails and freshwater mussels) excrete so that these mollusks function as engines that drive the transfer of a significant amount of the organic matter through aqautic ecosystems.
