The processes of thermal eutrophication of the cooling reservoirs of the Smolensk and Kursk nuclear power plants (NPP) were studied. Data characterizing changes in the concentrations of inorganic forms of nitrogen and phosphates in water during its heating in the NPP cooling system were obtained. Different aspects of the effect of heated water on the production–destruction processes are discussed. The conditions under which the intensity of thermal eutrophication can substantially increase were determined. 相似文献

We studied the organochemical distribution of saturated hydrocarbons in organic matter of mudstones of the Vendian Marna Formation in the Sayan-adjacent Biryusa area. The formation is composed of glacial, glacio-alluvial, and lacustrine deposits.In the fraction of saturated hydrocarbons in chloroform extracts (bitumoids), a homologous series of earlier unknown 2,7-dimethyl alkanes has been identified, with molecules having the even number of carbon atoms prevailing. The possible sources of such abundant biomarkers are considered. 相似文献
