** The goal of this study was to test whether the synthetic anionic surfactant sodium dodecyl sulfate, SDS, has an inhibitory effect on the ability of the planktonic filter-feeder, daphnia 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.
** CONCLUSION. It is the first time that it was demonstrated that the synthetic surfactant SDS decreased the rate of water filtration by the planktonic crustaceans D. magna.

It was discovered that plant biomass help towards restoration the water quality in the system which was polluted with a synthetic surfactant. Addition of sodium dodecylsulphate (SDS) to water rapidly changed the surface tension of water in the microcosm. 

The measurements demonstrated that the surface tension of water in the microcosm with the macrophyte OST1 restored to the level which was close to that of pure water within less than three days. As soon as after 46-h incubation of the system containing the plant phytomass, the surface tension increased significantly and reached that of distilled water. In the variants with water without plant phytomass, restoration of the normal surface tension was much longer (about 17 days). 

The results demonstrated an accelerated restoration of the normal surface tension which was typical of pure water in those systems that contained SDS in the presence of the phytomass of the macrophyte OST1. This is consistent with the conclusion that the macrophyte accelerates the disappearance of the surfactant from water. The results contribute new information to the scientific basis for water phytoremediation, innovative technology for water treatment and purification.

INFORMATION ON THIS SUBSTANCE (SOURCE: WIKIPEDIA):

Applications

SDS is mainly used in detergents for laundry with many cleaning applications.[5] SDS is a highly effective surfactantand is used in any task requiring the removal of oily stains and residues. For example, it is found in higher concentrations with industrial products including engine degreasers, floor cleaners, and car wash soaps. It is found in toothpastes, shampoos, shaving creams, and bubble bath formulations in part for its thickening effect and its ability to create a lather.[6] Pepsodent toothpaste at one time used the name "Irium" for its sodium lauryl sulfate ingredient.
Other names of the chemical: Sodium dodecyl sulfate, 
Sodium monododecyl sulfate; Sodium lauryl sulfate (SLS); Sodium monolauryl sulfate; Sodium dodecanesulfate; 
SDS = SLS;

It is a high production volume chemical (i.e., annual production and/or importation volumes above 1 million pounds in the United States).

Health and Safety Information on the Chemical


Acute Toxicity
Acute toxicity data in the rat show that SLS (=SDS) is harmful by the oral route (LD50 1200 mg/kg bw), and data in the rabbit and guinea pig show it is harmful by the dermal route (LD50 = ~600 mg/kg bw and >1200 mg/kg bw respectively).

Irritation
SLS (=SDS) is a skin and eye irritant in rabbits, and skin irritation has been observed in clinical studies in humans. Indeed in the human 4-hour patch test for irritation, SLS is used at 20% as a positive control to identify substances or preparations that would be on the borderlinefor classification as irritant. SLS is also reported  o irritate the respiratory tract.

Sensitisation
No data on skin sensitisation is available in these reviews. However, since OECD Test Guideline methodology for guinea pig skin sensitization predictive tests requires application of 10% SLS at induction to create local irritation for those test materials with no skin irritation potential, it is highly unlikely that SLS (=SDS) is a skin sensitiser as this could create concerns over potential cross sensitisation reactions at challenge with the test material.

Effects from Repeated Exposure
Oral (gavage) repeat exposure studies in rats showed the primary effect of SLS (=SDS) to be local irritation of the gastro-intestinal tract, with no effects seen at the 100 mg/kg bw/day dose level.

Genotoxicity
SLS was negative in an Ames (bacterial mutation) test, a gene mutation and sister chromatid exchange test in mammalian cells, as well as in an in vivo micronucleus assay in mice. The negative results from in vitro and in vivo studies indicate SLS does not interact with DNA.

Carcinogenicity
In the only carcinogenicity study available, SLS was not carcinogenic in Beagle dogs, though the short study duration and limited details provided limit the significance that can be attached to the data.

Reproductive Toxicity
No effect on fertility was seen in a study in male mice administered 100 mg/kg bw/day SLS, or on epididymal sperm in male mice administered SLS at a dose producing systemic toxicity: 1000 mg/kg bw/day. In developmental toxicity studies in the mouse and rabbit using doses of 0.2 to 600 mg/kg bw/day, total resorption of foetuses, increased litter loss and/or abortion were seen at 600 mg/kg bw/day in the presence of severe maternal toxicity. At 300 mg/kg bw/day no developmental toxicity was seen, though slight to moderate maternal toxicity was observed. Therefore, SLS is not considered a developmental toxicant, as the developmental effects seen were a secondary non-specific consequence of severe maternal toxicity.

Health and Safety Information on Formulations Containing Sodium Lauryl Sulfate


Information on formulations containing SLS at final tested concentrations ranging from 0.21 to 26% is available from studies for acute oral toxicity, and skin and eye irritation in animals, along with skin irritation and sensitisation clinical studies in humans. Together, these data support the findings on SLS that the chemical is of moderate acute oral toxicity, and irritant to the skin and eye in both animals and humans.

ABSTRACT.
Ostroumov S.A. Imbalance of factors providing control of unicellular plankton populations exposed to anthropogenic impact. - Doklady Biological Sciences, 2001. Vol. 379, P. 341-343. 4 tables. Bibliogr.12 refs. (Translated from DAN 2001. Vol. 379. P.136-138). ISSN 0012-4966 (Print) 1608-3105 (Online). PMID: 12918370 [PubMed - indexed for MEDLINE].
New concepts and new facts on aquatic organisms:
Innovative analysis of the factors that create environmental balance as related to plankton, which in turn is relevant to proper management of water resources, and water quality sustainability.The paper presents and analyzes new experimental data on the effects of chemical pollution of aquatic medium on the abundance of unicellular plankton organisms. The following 6 types of effects of filter-feeders and chemical pollutants [surfactants and detergents (mixtures)] on phytoplankton organisms were found (examples were given in this paper in Tab.2): (1) Inhibition of growth (and abundance); (2) Growth stimulation in the presence of surfactants and detergents; (3) Decrease in abundance as a result of elimination of plankton cells from water by the freshwater mollusks Unio tumidus and rotifers; (4) Abundance decrease as a result of water filtration by the marine mollusks Mytilus edulis, M. galloprovincialis, and Crassostrea gigas; (5) Decrease in the efficiency of cell elimination from water caused by the TX-100-induced (5 mg/l) inhibition of the filtration activity of the freshwater mollusks (freshwater mussels) Unio tumidus; (6) Decrease in the efficiency of cell elimination from water as a result of inhibition of the filtration activity of the marine mollusks Mytilus galloprovincialis and Crassostrea gigas induced by surfactants and Avon Herbal Care (hair shampoo). A new parameter and formula were suggested: the efficiency of cell elimination from water, ECE. The following maximum values of ECE were found (at the concentrations of the chemical, mg/l, in brackets): (1) Detergent OMO, Unio tumidus, 186.7 (50); (2) Detergent Losk-Universal, Mytilus galloprovincialis, 551.7 (7); (3) Detergent Tide-Lemon, Mytilus galloprovincialis, 206.9 (50); (4) Detergent IXI, M. galloprovincialis, 157.8 (10); (5) Detergent Deni-Automat, Crassostrea gigas, 10 800.0 (30); (6) Detergent Lanza, Crassostrea gigas, 261.7 (20); (7) Detergent Vesna-Delikat, Crassostrea gigas, 200.0 (1); The tables in the paper: Factors of regulation of unicellular plankton abundance (Tab.1); effects of surfactants and detergents on phytoplankton abundance (Tab.2); 7 detergents inhibit filtration of 3 species of marine and freshwater molluscs (Tab.3); Mytilus galloprovincialis eliminates from water the cells of Saccharomyces cerevisiae and algae Pavlova lutheri = M. lutheri as a result of filtration (comparing the 2 processes at the same time, Tab. 4). ** CONCLUSIONS. The results obtained in this work demonstrated and proved that certain pollutants might cause a substantial imbalance of the factors controlling unicellular plankton populations. Direct and indirect (mediated by organisms-consumers) effects of certain surfactant-containing mixtures on unicellular plankton could sum with each other, giving rise to mutual amplification. This may cause a complete imbalance of the system. The conclusions made in this work may be applied to unicellular plankton of both marine and freshwater ecosystems, including ecosystems subjected to eutrophication. The results contribute to issues of environmental safety and resource use sustainability.

Vol. 383: 147-150. Bibliogr. 15 refs. ISSN 0012-4966 (Print) 1608-3105 (Online). Distributed by Springer, orderdept@springer-sbm.com. ** ABSTRACT: As a result of the author’s studies of filter-feeders (DAN, 1998, Vol. 362, P. 574-576; DAN, 2001, Vol. 378, P. 283-285), it is clear that the filtering activity of populations of filter-feeders in natural habitats might be significantly reduced if the concentrations of some pollutants reach certain levels. The role of filter-feeders as factors of water purification in ecosystems is so important that their inhibition is a danger for the entire ecosystem. The author emphasizes that not only the biodiversity of filter-feeders but also their level of functional (filtration) activity is to be protected. In order to do so, the author suggested establishing a new type of protected areas whose main purpose is to protect functionally active populations of filter-feeders, including bivalves and other organisms. Those protected areas could be named hydrobiological (some variants: biofiltering, or malacological) reserves (some variants: refuges, sanctuaries, etc.). The author formulated 5 principles of nature conservation requirements in malacological and hydrobiological reserves (Tabl. 3). Among them is principle 2, "conservation of filtration activity of organisms and populations". The paper contains data on how 5 detergents (1-50 mg/L) inhibited the filtration activity of Unio tumidus, Mytilus galloprovincialis, Crassostrea gigas (Tabl. 2); on effects on the efficiency of elimination (EEE) of suspended matter from water were measured (Tabl. 2); on the number of days (0.3 – 10) needed to filter the volume of aquatic (freshwater and marine) ecosystem by the local bivalves (a review of data from literature) (Tabl. 1). "I suggest that the existing system of protected terrestrial and water areas should be supplemented with special sites intended to conserve populations of filter-feeders. In addition to biodiversity conservation, these populations should be conserved because they fulfill a very important biogeocenotic function of water filtration and purification" (p.149). "The system of five principles…is proposed to provide an ecological basis of the environment conservation conditions at these sites (malacological and hydrobiological reserves)" (p.149).].

Abstract: Changes in the concentrations of the four heavy metals in the water of experimental systems were studied. Using the method of inversion voltamperometry, the concentrations of the heavy metals Cu, Zn, Cd, Pb were measured in the water of the experimental microcosms. Aquatic macrophytes Ceratophyllum demersum were incubated in the microcosms. The measured concentrations of all four heavy metals decreased in the microcosms with the macrophytes much faster than in the control microcosms without any aquatic plants. The new results complement the previous data on the phytoremediation potential of aquatic plants.  The new facts proved that  Ceratophyllum demersum  is a potent tool to clean water and to remove heavy metals. This is the first time the phytoremediation potential (for the mixture of metals) of this wide-spread species  was discovered. The plant removed the toxic metals cadmium, lead, copper, zinc (Cd, Pb, Cu, Zn) from water with great efficiency. As a result, water quality improved dramatically with a prospect of new technology.

ABSTRACT: 
Study of biogenic migration of the chemical elements is an important line of the biosphere research [1–8]. Biogenic migration of the elements in aquatic ecosystems, both freshwater and saltwater ones, is important for water self- purification and water quality formation [9–11]. Data on element accumulation and binding by aquatic organisms, including macrophytes, are necessary for analyzing the organisms’ important role in biogenic migration of the elements in aquatic ecosystems. There were no published data on the gold (Au) content in Ceratophyllum demersum L. and on interaction between Au nanoparticles and aquatic macrophytes. The goal of this work was to study the immobilization of Au nanoparticles added to the water medium of microcosms in the presence of macrophyte C. demersum L. This study was the first to determine the concentration of Au and some other elements in C. demersum phytomass after incubation in microcosms containing Au nanosize particles (NSPs). Results of the experiments: (1) the first data have been obtained that demonstrate that a significant amount of Au NSPs may bind to live phytomass of an aquatic plant, C. demersum. As a result of binding and/or immobilization, the content of Au was greater than the background level by a factor of 430.3; (2) modification of NSPs with a protein (immunoglobulin) had no effect on the NSP immobilization by macrophytes. The results contribute to understanding the role of these organisms in biogenic migration of elements. These data enable us to estimate the participation of phytomass of the studied macrophyte species in element concentration (as exemplified by Au) in an aquatic system.

System of elements of the theory of biotic maintaining the natural purification potential of ecosystems. Basic elements are formulated for a qualitative theory of the multifunctional (polyfunctional) role of the biota in improving water quality and doing self-purification of water in aquatic ecosystems. The elements of the theory covers the following: sources of energy for the mechanisms of water self-purification; the main functional blocks of the system of self-purification; the system of the main processes that are involved; the analysis of the degree of participation of the main large taxa; the reliability of the mechanisms of water self-purification; regulation of the processes; the response of the mechanisms of water self-purification towards the external influences (man-made impacts, pollution); and some conclusions relevant to the practice of environment protection. In support of the theory, the results are given of the author's experiments which demonstrated the ability of some pollutants (surfactants, detergents, and some others) to inhibit the water filtration activity of marine filter-feeders, namely, the bivalve mollusks Mytilus galloprovincialis, Mytilus edulis, and Crassostrea gigas.
