A book was published on some contemporary issues of ecology, pollution of aquatic environment, and man-made impact of a relatively poorly studied group of chemical pollutants, detergents. The book was entitled:
Biological Effects of Surfactants. 
The domestic and industrial use of surfactants is widespread and affects the biosphere of the entire world by running into local watercourses. With important and growing repercussions for the food chain and the ecosystem, synthetic surfactants and detergents in the biosphere are of growing concern to environmental agencies, governments, and environmentalists around the world, and a detailed look at the impact of these compounds is long overdue. Biological Effects of Surfactants examines the effects of all types of surfactants, including anionic, non-ionic, and cationic surfactants, on a wide range of organisms, such as bacteria, algae, higher plants, and invertebrates. **

Question: which new aspects of environmental hazards from chemicals were identified in the book and other concomitant publications of the same author (S.A. Ostroumov)?
Answer: Several new types of environmental hazards from chemical pollution were identified in the book and in some other publications of the same author. One of those hazards is a risk of damage to natural processes of ecological remediation. Those processes lead to water self-purification in natural aquatic ecosystems (both freshwater and marine aquatic ecosystems). We published a special paper that is focused on this issue. See:
Ostroumov S.A. Identification of a new type of ecological hazard of chemicals: inhibition of processes of ecological remediation. Doklady Biological Sciences. 2002. 385: 377-379.

Question. Using chemicals that act as inhibitors of activities of enzymes was very productive in biochemistry. Is it possible to use chemicals that inhibit functions of organisms in ecosystems in order to get more information on ecological mechanisms?

Answer: yes, it is possible, and it was shown both in the book and in a special paper of the same author. The function inhibited was water filtration by freshwater and marine bivalves. The chemicals that inhibited this function were surfactants and detergents. See the paper:
**  Inhibitory analysis of regulatory interactions in trophic webs.- Doklady Biological Sciences, 2001, Vol. 377, p. 139–141. (Translated from Doklady Akademii Nauk, 2000, Vol. 375, No. 6, p. 847–849).
Full text: http://www.scribd.com/doc/45911405:
ABSTRACT: In the paper, the author proposed a new approach to analyze the key ecological issue, the interactions between organisms in ecosystems. The new methodology proposed is inhibitory analysis. The author applied this approach to analyze trophic chains: the top–down control of plankton by benthic filter-feeders. This control, as the author’s experiments have shown, might be removed by chemical inhibitors (the latter may enter the ecosystem as pollutants). As an example, the author gives the results of his experiments on how surfactants [tetradecyltrimethylammonium bromide (TDTMA)], and synthetic detergents inhibited the control of plankton (algae Monochrystis lutheri) by marine mussels Mytilus galloprovincialis. The method was successfully applied to innovatively analyze the factors that are among reasons of eutrophication. Among new facts: the cationic surfactant TDTMA 1 mg/L inhibited the filtration rate of juveniles of marine bivalves Mytilus galloprovincialis, and the removal of cells of the algae Monochrysis lutheri from water (50 min, 26˚C)].

Question: in the book, the author discovered that detergents and surfactants inhibit the feeding activity of bivalves. This in turn leads to inhibition of the production of pellets by bivaqlves. In turn, it leads to inhibition of biogeochemical flows of chemical elements that are present in the pellets. Is something analogous found with other types of mollusks, say, gastropod mollusks?

Answer: yes, the same author did found some analogous response with gastropod mollusks, namely the mollusk Lymnaea stagnalis. It was analyzed both in the book and in the paper:

ABSTRACT:   New data on coupling of geochemical and ecological (hydrobiological) processes. The role of freshwater mollusks Lymnaea stagnalis   in the flows of chemical elements in the biosphere was studied by detecting the elemental composition and amount of pellets produced by the mollusks.  For the first time, the following was quantitatively studied: the elemental composition (C, N, P, Si, Al) of pellets formed by mollusks Lymnaea stagnalis feeding on the leaves of higher plants Nuphar lutea and Taraxacum officinale; the amount (wet weight, dry weight) of pellets formed by L. stagnalis feeding on the leaves of N. lutea and T. officinale; the transfer of matter and chemical elements (C, N, P, Si, Al)  with pellets of freshwater bivalves (unionids Unio sp., etc.) per unit biomass of mollusks and per unit area of the ecosystem of the river; the transfer of matter and chemical elements (C, N, P, Si, Al) with pellets of L. stagnalis per unit biomass of mollusks and per unit area of the ecosystem of the pond. Synthetic surfactants ТDТМА 2 mg/l, SDS 1-2 mg/l, detergent Tide-Lemon 75 mg/l inhibited the trophic activity of L. stagnalis.

Question. Given the fact that you studied mollusks and presented lots of new information about how useful they are in your book, can you offer some new things on how to protect the populations of mollusks from decline and extinction?

Answer: Yes, the new steps towards protecting populations of mollusks were suggested by the author of the book in  a special paper:
** System of principles for protecting the biogeocenotic function and biodiversity of filter-feeders. — DAN. 2002. V. 383. No. 5. P. 710-714.  Full text: http://www.scribd.com/doc/45911862;

Bibliogr.15 refs.  In Russ., translated into English: System of principles for conservation of the biogeocenotic function and the biodiversity of filter-feeders.- Doklady Biological Sciences. 2002 (March). 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).].

Bibliogr.15. ISSN 0012-4966.

ABSTRACT:. In the paper, a new discovery is reported  of a new type of negative impact of pollutants on the biosphere, as a result of inhibition of water filtration by filter-feeders / suspension feeders. The water filtration and associated removal of suspended matter from water is part of migration of matter. As V.I. Vernadsky stressed, organisms are the mediators of “biogenic migration of atoms in the biosphere”. This migration is partly implemented in the framework of pelagial–benthal coupling via the activity of filter-feeders, which remove the organic suspended matter from water and excrete pellets. The tables contains the following data: the average percentage of assimilated (16-90%) and non-assimilated (10-84%) food matter for 15 large taxa of invertebrates (Table 1); potassium bichromate inhibited water filtration by mussels Mytilus galloprovincialis (Table 2); surfactants, detergents, pesticides inhibited filtration by filter-feeders, marine and freshwater bivalves and rotifers (Table 3). A prediction was made: "Further research and experimental studies are expected to provide new evidence that sublethal concentrations of chemical pollutants induce a significant decrease in the filtration capacity of freshwater and marine filter feeders" (p.129). "The uncoupling process considered above is an anthropogenic violation of two basic laws (empirical rules or biogeochemical principles) of the biosphere functioning: (1) biogenic migration of atoms of chemical elements in the biosphere always tends toward its maximum expression; (2) on the geological time scale, the evolution of species gives rise to the forms of life that are stable in the biosphere, and is so directed that the biogenic migration of atoms in the biosphere increases" (p.129).]; DOI10.1023/A:1015385723150; https://www.researchgate.net/file.FileLoader.html?key=d988acb599e121964c48114374a87e8d;www.springerlink.com/index/28V23JBFADL1Y100.pdf;

The level-block approach to the analysis of ecological hazards of anthropogenic effects on the biota (the new conceptualization proposed by the author). Some fundamental principles that characterize the pivotal roles of the biodiversity of filter-feeders in ecosystems. Among those roles are: (1) the role of ecological repair of water quality, (2) the role of contributing to reliability and stability of the functioning of the ecosystem, (3) the role of contributing to creation of habitat heterogeneity, (4) the role of contributing to acceleration of migration of chemical elements. It is an important feature of the biomachinery of filter-feeders that it removes from water various particles of a very broad range of sizes. Another important principle is that the amount of the organic matter filtered out of water is larger than the amount assimilated so that a significant part of the removed material serves no useful function to the organism of the filter-feeder, but serves a beneficial function to some other species and to the ecosystem as a whole. The new experiments by the author additionally demonstrated a vulnerability of the filtration activity of filter feeders (e.g. bivalves and rotifers) to some   xenobiotics (tetradecyltrymethylammonium bromide, heavy metals and some others). The inhibition of the filtration activity of filter-feeders may lead to the situation previously described as that of an ecological impairment of the second type.

Question: In the book, you have studied organisms that filter water. Among them, you studied the organisms that live at the bottom of lakes, streams and seas. Did you study some other organisms which live in the water column?

Answer: yes, we studied those organisms. We studied zooplankton. We made experiments with representatives of the two major groups of zooplankton. Those groups are rotifers (Rotifera) and crustaceans (Cladocera). A typical crustacean species of zooplankton is Daphnia magna. Recently, we did some successful experiments with Daphnia magna. The results of those new experiments were in accord with the results of our previous experiments with mollusks. The new experiments with Daphnia magna are reported by us in the paper (see below):-

Question: You identified some new problems, some new hazards from chemical pollutants. Can you offer some solutions to those problems?

Answer: I am very happy to answer that we really can offer some solutions. We explored some aquatic vegetation  - some species of aquatic plants. Those species of aquatic plants are our hope. Those aquatic plants can be used as the basis of innovative technology to make water clean. This innovative technology is called phytotechnology, or phytoremediation. We recently published a series of papers on phytoremediation. This work was done together with a graduate student, Elena Solomonova. An example of a paper that we published with her is given below:

Abstract: Macrophytes are important components of ecosystems and participate in the purification of water, which contributes to the sustainability of water quality. This is especially important in conditions of pollution of water bodies and water streams. Surfactants constitute an important class of pollutants. Therefore, further investigation and clarification of the facts concerning the interaction of plants and various surfactants 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 macrophytes, the pondweed Potamogeton crispus L. When the effects of the anionic surfactant sodium dodecyl sulphate on the aquatic macrophytes Potamogeton crispus L. were studied, it was found that the 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). DOI:10.3103/S0096392507040074;
