Article
Patterns of bioaccumulation of polychlorinated biphenyls (PCB) by chironomid larvae (Chironomus riparius Meigen) were studied under laboratory conditions. Larvae were maintained for 20 days, separately in two batches of natural bottom sediments sampled from Rybinsk Reservoir (Russia), each differing in PCB content (425.6 µg / kg or 24.8 µg / kg dry...

Long-term dynamics of the aquatic toxicity was studied in the Rybinsk Reservoir. According to the biotesting, the Volga and Sheksna reaches were the most polluted areas, which were exposed to household and industrial wastewater, as well as to the diffuse runoff from agricultural land and major highways. The relationships between the parameters of t...
Article
Full-text available
It is shown that the number of deformations of mouthpart structures of larvae Chironomus riparius reflects the potential danger of contaminated bottom sediments and can serve as a good biomarker when monitoring the ecological status of freshwater ecosystems. The method of quantification of the deformation rate of hard-chitinized structures (mentum...

Abstract: The book generalizesthe results of the integrated monitoring of the ecosystem and special studies in the Rybinsk Reservoir during the years of its existence with a particular emphasis on the period of the last 15 years. The work highlights fundamental problems of hydrobiology and ecology, and the relationships between the long-term dynami...
Article
The levels of metal content and toxicity have been determined in bottom sediments of water bodies in Central and South Vietnam. It is found that the concentration of metals (As, Cr, Cu, Hg, Ni, Pb, and Zn) exceed the value of the abundance of elements in the Earth’s crust, which may be associated with geochemical features of the province. Acute tox...
Article
Full-text available
The effect of lethal and sub-lethal concentrations of lanthanum on the survival, growth and reproductive parameters of cladoceran Ceriodaphnia affinis in acute and chronic experiments are presented.
Article
Full-text available
The effect of titanium dioxide (anatase and rutile isoforms) nanoparticle suspensions on the biological parameters of some freshwater animals of various systematic statuses has been studied. The most sensitive are Ceriodaphnia affinis Lillijeborg, 1862; the most resistant are zebra fish Danio rerio Hamilton-Buchanan, 1822. Anatase in concentrations...
Article
Deformations of hard-chitinized mouthpart structures (mentum and mandibles) in larvae of the genus Chironomus affected by organic pollution have been studied. A system for the quantitative assessment of these structures has been developed. Indices for the severity of mental and mandibular deformation have been calculated. They allow one to determin...
Article
Full-text available
An ecotoxicological assessment is given to the state of small lakes in specially protected natural areas in Northwestern and Central European Russia, which suffer from aerotechnogenic acidification. The toxicity of water and bottom sediments is shown to increase with decreasing water pH. The most sensitive characteristics of aquatic organisms in di...
Article
Data on the effects of various forms of zinc compounds on the biological parameters of freshwater animals (Ceriodaphnia affinis Lillijeborg, 1862; Chironomus riparius Meigen, 1804; and Brachydanio rerio Hamilton-Buchanan, 1822) are presented. Crustacean Ceriodaphnia affinis is the most sensitive test object studied.
Article
The effect of sublethal concentrations of the fine-dispersed (cluster) silver on morphometric characteristics and reproduction of the planktonic crustacean Ceriodaphnia affinis was studied. In the freshwater ecosystems changes of the population number and fertility of crustaceans, which serve as food supply for other aquatic organisms, can negative...
Article
Data on the effect of nano- and microparticles of cerium and titanium dioxides and zinc oxide on the survival rate and reproduction of nanoflagellates and ceriodaphnia are given. The inhibitory effect of metal oxide nanoparticles on nanoflagellates Bodo saltans Ehrenberg manifested itself in a decrease in their population after 3–4 days of exposure...
Article
Full-text available
The toxicity of bottom sediments (BSs) from different parts of the Rybinsk Reservoir has been determined by biotesting. Neither acute nor chronic toxicity are detected for ceriodaphnia Ceriodaphnia affinis Lillijeborg in tests with water extracts of sediments from all the investigated stations. The relative number of Chironomus riparius Meigen larv...
Article
Main regularities of different mercury compounds accumulation by planktonic Crustacean Ceriodaphnia affinis have been studied in experiment. Sublethal concentrations of mercury compounds were contained either in medium or in food. Peculiarities of their impact on animals depending on pathway of income into the organisms have been revealed.
Article
The effects of various mercury chloride (HgCl2) concentrations associated with bottom sediments on mercury accumulation in chironomid larvae and the modifications of morphofunctional parameters (mortality, growth, and structure of the mouth apparatus) have been studied. It was shown that, upon exposure, the larvae accumulated mercury in amounts exc...
Article
The physicochemical, toxicological, and teratological properties of bottom sediments in Karelian lakes (Vuontelenjarvi, Suojarvi, Venderskoe, and Chuchjarvi) and Kondopoga Bay of Lake Onega are studied. Bioassay results testify to a high toxicity of bottom sediments in heavily acidified lakes (with the water pH of 5.5 and lower).
Article
Bioassay methods are used to assess the toxicity of bottom sediments in the main watercourses of the Selenga River basin and Lake Orog in Mongolia. Toxic bottom sediments are found in a brook in the region of the Erdenet Mining and Concentration Complex, as well as in the Eroo and Bukhlyn rivers, which experience the effect of intense gold mining....
Article
Changes in the levels of mercury in the fish inhabiting the water reservoirs of Russia were studied after cooking it in a variety of ways (boiling for different time periods, roasting, and smoking). To have a general idea of the impact of various procedures for cooking the fish on its mercury amount, the authors measured mercury concentrations in s...
Article
Statistical methods of data analysis have been used to study the correlation between the benthic characteristics and the geochemical and toxicological characteristics of bottom sediments of the small river of Sestra. As shown, a relatively wide scope of biological and chemical data is needed to assess the quality of bottom sediments of the Sestra R...
