The results of studying the concentrations and component composition of hydrocarbons and associated oxidized hydrophobic compounds in water bodies with different degrees of oil product pollution are given. It is shown that the role of biogenic hydrocarbons in the assessment of oil pollution of freshwater bodies, especially those having high biological productivity, can be quite significant. Such assessment requires the examination of their genesis by using the proposed gas-chromatographic and luminescent criteria. The most informative object for observations in the identification of oil and biogenic hydrocarbons for the assessment of chronic oil pollution of freshwater bodies is bottom sediment. 相似文献

Based on analyzing long-term (1968–2010) national monitoring data from Rosgidromet and other agencies as well as on research results for the Lower-Don and Kuban’ river basins, we identified observation posts on water bodies with a stably high pollution level and gave a characterization of the spatiotemporal tendencies of its changes. Long-term changes in water quality are exemplified by an alternation of periods of increasing and declining pollution; its level showed a decrease from the period 1980–1990 to the end of the last decade. 相似文献

The results of assessments of the water community state with allowance for a chronic character of pollution with heavy metal
compounds are presented based on the analysis of the long-term hydrochemical and hydrobiological information of the State
Service of Observations over water bodies of the Kola North. Characteristic signs of changes in quantitative and qualitative
indicators of phyto-and zooplankton development relative to the concentration level of nickel and copper compounds and other
pollutants are noted. 相似文献

Underflooding of different extent was recorded in 133 populated localities in southern Rostov oblast, among which 4 such localities are always partly underflooded, and 77 localities suffer underflooding during spring floods and freshets. Minimal estimates show that the area of the territories underflooded every year and only in wet years is 282 km2 or 19% of the total built-up area in the southern Rostov oblast. Technogenic factors were found to dominate as the causes of underflooding in the majority of the populated localities. However, natural or slightly disturbed subsoil water regime is typical of the built-up territories in the southern Rostov oblast, where it implies annual periodicity of level variations with a peak in spring and a minimum in autumn. 相似文献

The structure of hydrobiocenosis communities in Lena River mouth area is studied. The qualitative and quantitative development
characteristics of bacterio-, phyto-, zooplankton, and zoobenthos communities of aquatic organisms in this part of the river
are examined. The state and structure of hydrobiocenosis suggest that the mouth area of the river functions under moderate
pollution of the aqueous medium. 相似文献

The discharge of organic and biogenic substances by Russian rivers into the Baltic, Black, Azov, and Caspian seas and into
Lake Baikal, as well as their anthropogenic component, and trends in variations in the runoff of ingredients are evaluated
for individual periods in 1981–2000. 相似文献

This report gives the conceptual approaches to the development of the theory of the formation of natural water composition
in view of the primary properties of aquatic ecosystems: the “principle of uncertainty” in the estimation of the conditions,
the “continuity” of the changes proceeding, and the “plurality” of water’s natural structure and components (biotic and abiotic),
as well as their interaction processes. The importance and features of each of these basical criteria for characterizing the
conditions of an aquatic ecosystems are substantiated in theory. 相似文献
