Dokl Biol Sci. 2001, 380: 499-501. Full text: http://www.scribd.com/doc/50526301/1-The-Hazard-of-a-Two-Level-Synergism-DBN; Abstract: Ostroumov S.A. The hazard of a two-level synergism of synecological summation of anthropogenic effects. - Doklady Biological Sciences, 2001, Volume 380, Numbers 1-6, p. 499-501. The author identified a new type of ecological hazard of anthropogenic impact (using chemical pollution as an example), which he proposed to term “synecological summation” or “synergistic summation” of anthropogenic effects on organisms of two adjacent trophic levels. In the paper, the hazard was found that even relatively mild influences on organisms of two adjacent trophic levels may eventually produce a synergistic, pronounced and definitely undesirable effect that will lead to an abnormal increase in the abundance of organisms of one of the trophic levels. The concrete examples of synergism were found when anthropogenic impacts affected organisms of two adjacent trophic levels (bivalves and algae). Negative effects (inhibition of water filtration) were described of the action of synthetic detergent Vesna (1 mg/l) on oysters Crassostrea gigas, detergent IXI (10 mg/l) on mussels Mytilus galloprovincialis, and detergent Tide-Lemon (50 mg/l) on M. galloprovincialis. The danger of simultaneous influence of contamination of environment (e.g., by detergents) on organisms of the two trophic levels may occur when the polluting chemicals produce effects on algae and bivalves that are filter-feeders.

The synecological approach to the problem of eutrophication. Ostroumov S.A. Dokl. Biol. Sci. 2001, 381: 559-562. PMID: 12918433 [PubMed - indexed for MEDLINE] Abstract: A new approach to combat eutrophication. The author suggests a new component of the measures against eutrophication: reducing the input of the pollutants that weaken the potential of the filter-feeders for removing phytoplankton (algae, cyanobacteria). Among new facts: the liquid detergent Fairy 2 mg/L inhibited filtration by the bivalve filter-feeders Mytilus galloprovincialis within 2-23 min (22.5 ºС) after addition.

In recent years, the importance of the problem of eutrophication of various aquatic ecosystems has been progressively increasing [1–3]. According to the survey of the trophic status of inland waters in 23 states performed by the United States Environment Protection Agency (EPA), eutrophic, mesotrophic, and oligotrophic lakes account for 45, 26, and 12% of the total number of lakes, respectively (the trophic status of 17% lakes was identified as “uncertain”) [3]. The eutrophication index of inland waters in some European countries (e.g., the Netherlands) is about 300, which is substantially higher than the desired level (about 100) and the level of stability (about 80) [2]. Eutrophication aggravates the problem of insufficient availability of water to people worldwide. According to the Global Accord estimates [4], the availability of water is expected to decline significantly in the foreseeable future in many countries. For example, from 1990 to 2025, the availability of water (m 3 per capita) in Algeria will decline from 750 to 380; in Kenya, from 590 to 190; in Libya, from 160 to 60; in Israel, from 470 to 310; and in Jordan, from 260 to 80. The current knowledge on the anthropogenic impact on aquatic organisms should be used to solve the problem of eutrophication. The role of nutrient substances in water eutrophication and possible approaches to reduction of the inflow of nutrient substances to water have been the main subjects of ecological studies on eutrophication thus far [1, 2]. Although these aspects of water eutrophication remain very important, they do not cover the entire spectrum of approaches to the problem. The goal of this work was to consider analytical approaches to the problem of eutrophication and to formulate a dualistic (two-component) approach to its solution. Based on the current ecological knowledge (including our own data and their analysis reported in [5–11]), a two-component solution of the problem of eutrophication is thought to be valid if two factors of phytoplankton abundance in water are taken into account. These factors are the availability of nutrient substances and phytoplankton elimination by organisms of the next trophic level. The two factors provide a methodological basis of the two-component approach to the problem of eutrophication. According to this approach, these factors can be used to control the ecological situation in water. The first component is the availability of nutrient substances in water. Reducing the rate of the inflow of biogenic substances to water can change the ecological state of the system. This well-understood method is widely used in practice [1, 2]. The second component of this approach concerns biological mechanisms of elimination of phytoplankton cells from water. These mechanisms include the filtration activity of

Hydrobiologia, 2002, vol. 469, p. 117-129; Auteur(s) / Author(s): OSTROUMOV S. A. (1) ; Résumé / Abstract: 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. The paper is focused on the role of benthic filter feeders in the control of plankton populations as a result of water filtering and the removal of cells of plankton from the water column. New data on the inhibitory effects of surfactants and detergents on benthic filter-feeders (Unio tumidus, U. pictorum, Mytilus galloprovincialis, M. edulis and Crassostrea gigas) are presented and discussed. Importance and efficiency of that approach to the problems of eutrophication and water self-purification is pointed out. Chemical pollution may pose a threat to the natural top-down control of phytoplankton and water self-purification process. The latter is considered an important prerequisite for sustainable use of aquatic resources. Hydrobiologia ISSN 0018-8158 CODEN HYDRB8 2002, vol. 469 (208 p.)

Impact of Dam Construction on Water Quality and Water Self-Purification Capacity of the Lancang River, China. - Water resources management; 2009, vol. 23, no. 9, pp. 1763-1780; GUOLIANG WEI (1 2) ; ZHIFENG YANG (1) ; BAOSHAN CUI (1) ; BING LI (2) ; HE CHEN (1) ; JUNHONG BAI (1) ; SHIKUI DONG (1) ; Affiliation(s) du ou des auteurs / Author(s) Affiliation(s): (1) State Key Laboratory of Water Environment Simulation, School of Environment, Beijing Normal University, Beijing 100875, CHINE; (2) Nuclear and Radiation Safety Centre, State Environmental Protection Administration, Beijing 100088, CHINE; Résumé / Abstract: Along with the sequent completion of Manwan and Dachaoshan Dam, the river continuum of the middle and lower reaches of the Lancang River was separated into three types of segments: reservoir, below-dam segment and downstream flowing segment. The long-term series of water quality and river flow data over 20 years were analyzed in order to study the impact of dam construction and operation on water quality and water self-purification capacity of these different river segments. From pre-dam period to the first 7 years after Manwan Dam had been accomplished, the water quality of Manwan Reservoir became worse due to the accumulation of pollutants, and then to the next 5 years the water quality became better in virtue of the water self-purification of the reservoir. The cooperative operation of Manwan and Dachaoshan Dam had cumulatively positive impacts on water quality of their below-dam segment but no impacts on that of downstream flowing segment. From pre-dam period to the first 7 years after the closure of Manwan Dam, the water self-purification capacity of Xiaowan―Manwan segment for BODS, CODMn and NH3― N decreased. Also, the water self-purification capacity of Manwan―Dachaoshan segment for BOD5 and CODMn decreased but for NH3―N increased. However, the water self-purification capacity of Jinghong―Ganlanba segment changed contrary to Manwan―Dachaoshan segment. In general, the construction of Manwan Dam negatively affected the water self-purification capacity of reservoir and below-dam segment but impose little impact on that of downstream flowing segment. This study suggested that it is necessary to pay attention to the effect of complicated temporal and spatial characteristics of dam on aquatic ecosystem.

Because effluent-dominated and dependent water bodies have previously received limited scientific study, we reviewed select contemporary topics associated with water quality of ephemeral streams receiving effluent flows. Our findings indicate that these ecosystems present numerous challenges to aquatic scientists and water resources managers, including: 1) appropriate ecosystems or upstream conditions used reference sites in biomonitoring are difficult to locate or do not exist; 2) water quality criteria, particularly for metals, are dramatically influenced by unique site-specific stream and land use conditions; 3) effluent-dominated streams represent worse-case scenarios for evaluating and predicting aquatic responses to emerging contaminants (e.g., pharmaceuticals and personal care products); 4) low-flow and drought conditions often preclude effective biomonitoring and water quality interpretation, or skew ambient assessment results; 5) chemical-physical water quality parameters (e.g., dissolved oxygen, conductivity, temperature) are dramatically altered by effluent and stormwater characteristics; and 6) beneficial reuse of reclaimed effluent waters potentially conflict with sustainability of ecological integrity. Subsequently, we recommend several water quality research priorities for effluentdominated water bodies.

Lake water is used for drinking purpose by 14 million people who live in the Shiga, Kyoto and Osaka prefecture. The water quality of the lake varies with the geographical features of the lakeside and other characteristics such as reed field, sandy, planty and rocky shores. These shores serve as an important natural purification system to protect the lake from water pollution and eutrophication that is becoming a serious concern. In water of this time we estimate cations (Ca, Mg, Na and K), anions also (HCO3, SO4, Cl).
