Earlier, the author published two books (including 'Introduction to Biochemical Ecology', Moscow University Press, 1986) and some papers, in which he described the conceptual foundations of a new scientific discipline — biochemical ecology. The lines of research on biochemical ecology included studies of the role of chemical substances in interorganismal interactions, in communication and regulation of supraorganismal systems.

Another part of biochemical ecology concerns studies of the fate and transformation of external chemical substances when they interact with the organisms. Both natural and man-made compounds are within the focus of biochemical ecology. The basic concepts of biochemical ecology include two concepts and terms that were suggested by the author, namely ecological chemomediators and ecological chemoregulators. They were suggested by S.A.Ostroumov and since then, they have already been included accepted as part of modern ecological concepts and are used in modern ecological literature. Application of biochemical ecology to aquatic ecosystems creates the basis for development of biochemical hydrobiology.

Basics of the molecular-ecological mechanism of water quality formation and water self-purification На фото: Basics of the molecular-ecological mechanism of water quality formation and water self-purification, автор: ar55

Water self-purification is an important example of ecosystem services. This function of aquatic ecosystems is necessary for sustainable development, and for sustainable use of aquatic resources (water resources), as well for environmental safety.
The analysis made by the author in a published paper (Ostroumov, 2008) showed that aquatic ecosystem (both marine and freshwater one) features a multi-component
molecular-ecological mechanism for upgrading water quality. In other words, it is a multi-component, multi-process biomachinery for water quality formation and self-purification. The biomachinery includes the following items: (1) sources of energy for self-purification mechanisms, (2) the major taxa of living organisms as components of the biomachinery; (3) the biomachinery contains the functional blocks that perform functions of filters, mills, and pumps.
Experiments that the author carried out demonstrated how several types of chemical pollutants may produce damage to this delicate and very useful biomachinery which makes water clean. The experiments demonstrated that some chemical pollutants decreased important and useful functions of aquatic invertebrate animals which contribute to purification of water. We have found that the chemical pollutant as diverse as synthetic surfactants, detergents, salts of Cd, Cu, Pb, Hg, Co, Ti, V (Na3VO4 •12 H2O), and oil hydrocarbons inhibited water filtration by bivalve molluscs, the marine mussels (the Latin name of the mussels: Mytilus galloprovincialis).
One of the practical conclusions is that we now see another aspect of important hazard from the low, sublethal concentrations of the chemicals that pollute the aquatic environment. Not only death of aquatic organisms, but also even a decrease of their functional activity in polluted aquatic ecosystems poses some danger and risk to the water system. The potential hazard of those low levels of the chemical pollutants is that the potential of the ecosystem to purify water will be decreased. As a final result, in future we may have water of worse quality.
This may be of interest to scientists and specialists in the following fields: aquatic ecology, water science, environmental toxicology and chemistry, ecotoxicology, and water resource management.

NEW SOLUTIONS TO COMBAT POLLUTION, ALGAL BLOOM, EUTROPHICATION: ARTICLE: Inhibitory analysis of top-down control: new keys to studying eutrophication, algal blooms, and water self-purification // Hydrobiologia. 2002. vol. 469. P.117-129. 8 tables. Bibliogr. 71 refs. [Top-down control is an important type of interspecies interactions in food webs. It is especially important for aquatic ecosystems. Phytoplankton grazers contribute to the top-down control of phytoplankton populations. This article is focused on the role of benthic suspension-feeders (filter - feeders) in the control of plankton populations as a result of water filtering and the removal of suspended matter (including the cells of plankton) from the water column. New data on the inhibitory effects of synthetic surfactants and detergents on benthic filter-feeders (freshwater mussels Unio tumidus, U. pictorum, marine mussels Mytilus galloprovincialis, M. edulis, and oysters Crassostrea gigas) are presented and discussed. Importance and efficiency of that approach to the problems of eutrophication and water self-purification is pointed out. The chemical pollution may pose a threat to the natural top-down control of phytoplankton and water self-purification processes. The latter are an important prerequisite for sustainable use of aquatic resources. Surfactant SDS at a concentration of 0.5 mg/L inhibited water filtration by Crassostrea gigas, at a concentration of 1.7 mg/L suppressed the filtering activity of M. galloprovincialis, at that of 1-5 mg/L decreased water filtration by M. edulis. The non-ionic surfactant Triton X-100 (TX100) at a concentration of 0.5-5 mg/L induced a sharp slowdown in water filtration by M. edulis, at 1 and 5 mg/L it caused a decrease in the filtration rate by the freshwater bivalve Unio tumidus. The cationic surfactant TDTMA at 1-2 mg/L constrained the filtering activity of the freshwater bivalve Unio pictorum. 4 detergents (6.7-50 mg/L) hindered the filtration by M. galloprovincialis. 3 detergents (1-30 mg/L) slowed down the clearance rate during water filtration by Crassostrea gigas. The shampoo AHC (Avon Herbal Care) at concentrations 5-60 mg/L arrested the filtration by M. galloprovincialis.

ARTICLE: Polyfunctional role of biodiversity in processes leading to water purification: current conceptualizations and concluding remarks // Hydrobiologia. 2002. v. 469 (1-3): P.203-204. Bibliogr. 8 refs. ISSN 0018-8158 (Print) 1573-5117 (Online). [Selected elements of a new vision of the role of biodiversity in water purification and maintaining the natural purification potential of ecosystems, elements of the theory of water self-purification. 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].

. Biological filtering and ecological machinery for self-purification and bioremediation in aquatic ecosystems: towards a holistic view // Rivista di Biologia / Biology Forum. 1998. 91: 247-258. According to one of the approaches to the definition of criteria for the phenomenon of life, the key attribute is the ability of the system for some self-regulating and self-supporting. Part of such holistic functions of aquatic ecosystems as self-regulating and self-supporting is their cleaning the water via a multitude of various mechanisms. The goal of this paper is to present some fundamental elements of the theory of ecosystem self-purification which emphasizes the importance of the four functional biological filters that are instrumental in purification and upgrading the quality of water in aquatic ecosystems. These functional filters are: (1) direct water filtering by aquatic organisms that are filter-feeders; (2) the filter (represented mainly by communities of aquatic plants/periphyton) which prevents input of pollutants and biogenic elements (N, P) from land into water bodies; (3) the filter (represented by benthic organisms) which prevents re-entry of pollutants and biogenic elements from the bottom sediments into the water; (4) the filter (represented by microorganisms attached to particles which are suspended in the water) that provides microbiological treatment of water column. New experimental data by the author reveal the role of man-made effects on the ecological machinery which purifies water. The analysis and discussion lead to the holistic theory of the natural process of bioremediation of aquatic ecosystems. [An innovative analysis of the role of organisms in water filtration in ecosystems. Water filtration is a key component of ecological biomachinery for maintaining the natural purification potential of ecosystems. Among new facts: the synthetic surfactant SDS 1 mg/L inhibited filtration (35-95 min, 16°С) of bivalve Mytilus edulis and the removal of the cells of algae Isochrysis galbana from water. Amount of cells that stayed in water unfiltered after 95 min, was 3 times as much as the amount of cells in the control without SDS].

(Translated from DAN, V.396, No.1, 2004, p.136–141). Basic elements are formulated for a qualitative theory of the 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.

АННОТАЦИЯ [Книга] Уровни охраны живой природы. М.: Наука, 1985. 176 с., ил. Библиогр.: с.169-172. [Совместно: Яблоков А.В., С.А.Остроумов.] Усл. печ.л. 9,24. Уч.-изд. л. 10,0. Отв. ред. академик Н. Г. Хрущев. http://scipeople.com/publication/99117/; Детально разработан предложенный в работе тех же авторов (Яблоков, Остроумов, 1983) принцип анализа проблем охраны живой природы и сохранения биоразнообразия по уровням организации живых систем. Впервые сформулирована система аксиом охраны живой природы, изложены особенности вклада основных биологических дисциплин в научные основы охраны живой природы.
В книге «Уровни охраны живой природы» (1985) и в предыдущей книге тех же авторов (Охрана живой природы, 1983) новый концептуальный подход – основанный на рассмотрении уровней организации живых систем - был использован для систематизации данных о антропогенного воздействиях на биосферу. В книгах (Яблоков, Остроумов, 1983, 1985; 1991) разработаны некоторые концепции, которые помогли организовать и классифицировать - с использованием логичной и современной системы - большой объем фактической информации об охране живой природе, о сохранении биоразнообразия и устойчивом использовании живых (биологических) ресурсов. В этих книгах новый научный подход был использован для того, чтобы классифицировать и систематизировать разнообразные и разобщенные ранее фактические данные о современных антропогенных воздействиях на биосферу. Этим подходом, как отмечалось выше, был анализ по уровням организации живых систем. Согласно этому подходу, следующие уровни организации живых систем рассматриваются в качестве основы для систематизации данных об антропогенном воздействии на биоту: 1. Молекулярно-генетический уровень; 2. Уровень организмов и онтогенеза; 3. Уровень популяций и видов; 4. Уровень экосистем и биосферы. Этот подход, как отмечалось, оказался эффективным в систематизации широкой и разнообразной информации об антропогенных воздействиях на живую природу (на биоту и живые ресурсы). Упомянутый подход вносит вклад в то, что большой объем фактической информации об антропогенных воздействиях и нарушениях в биосфере сводится в логическую и современную систему, что важно для учебного процесса. Цитируемые книги используются в обучении студентов в области охраны природы, экологии и других научных дисциплин.

—Principles of the theory of the ecological mechanism of water self-purification based on multiple
functions of the biota in freshwater and marine ecosystems are formulated. In developing this theory, the results
of the author’s experiments with filtering hydrobionts have been used. These results indicate that the water selfpurification
mechanism is vulnerable to the impact of some pollutants and, in particular, surfactants. Conclusions
drawn on the basis of the theory have practical significance for biodiversity conservation and for the sustainable
use of the biological resources of aquatic ecosystems.

This is the first time it was shown that the nanoparticles of gold (Au) in substantial amount bind to the living biomass of the aquatic macrophyte, Ceratophyllum demersum. The concentrations of Au were measured in the samples of the phytomass using neutron activation analysis (NAA). As a result of the binding and/or immobilization of the nanoparticles, the amount of Au in the samples of the phytomass increased manifold (by a factor of 430) above the background level of gold in the plant tissues. The increase was by two orders of magnitude. The new data added some new information to the modern vision of the multifunctional role of the biota in the migration of elements in aquatic ecosystems. Also, the result added some new information to the studies of interactions of Au with organisms that may contribute to new biotechnologies.

Аннотация : Исследования экологии живых организмов ведут к более глубокому пониманию сложнейших процессов функционирования биосферы Земли. Человечество пока далеко даже от попыток установить с ней гармоничные отношения.
Между тем постоянно нарастающие масштабы разрушения техногенной цивилизацией природных комплексов требуют революционных подходов к их сохранению.
Вот почему важно изучать существующие взаимосвязи и взаимодействия живых организмов. Одну из важнейших ролей в этом "оркестре" играют многочисленные беспозвоночные, фильтрующие воду и тем очищающие ее. В какой степени на эту их способность влияют химические вещества-загрязнители?

Из текста: «указанные в данной статье исследования вносят вклад в расшифровку такой концепции [аппарата биосферы]» (стр. 35-36); «… раздробленность биосферы на множестов индивидуальных особей создает предпосылки для специализации и распределения между ними функций, полезных для нее в целом» (с.36); «нарушение фильтрации воды беспозвоночными создает новый вид опасности для стабильности климата планеты»; «В результате мы лучше видим, с одной стороны, детали аппарата биосферы, а с другой – интегрированность организмов в единое целое»; «В практическом плане один из итогов состоит в построении более адекватной системы критериев оценки степени опасности антропогенных воздействий, в выявлении новых ее видов. Это нарушение связей между организмами, а также их функций, полезных для поддержания чистоты воды» (с.36). Translated into English: Biological filters are an important part of the biosphere // Science in Russia. 2009. No. 2. P. 30-36. ISSN 0869-7078. Abstract: Studies of ecology of living organisms lead to a more profound understanding of the intricate processes of the Earth’s biosphere functioning. The mankind is still far from establishing harmonious relations with it. However, permanently progressing destruction of natural complexes by the technogenic civilization necessitates some new revolutionary approaches to their preservation. That is why it is so important to study the relationships and interactions between living organisms. One of the most important roles in this “orchestra” is played by numerous invertebrates which filter the water and improve water quality. To what degree chemical pollutants modify their capacity to do this vital ecosystems service?
