(E,Z)‐2‐bromo‐1‐(2,4‐dichlorophenyl)vinyl bis[ethyl‐2H5] phosphate ([2H10]bromfenvinphos), a regiospecifically deuterium‐labelled pesticide, was synthesized in two steps starting from [2H6]ethanol, phosphorus trichloride and 2,4‐dichlorophenacylidene bromide, and fully characterized. The deuterated biologically active bromfenvinphos is an important compound for the advancement of environmental degradation testing and some mass spectrometric studies.

“…The aquatic monitoring system allows us to avoid some formalization inherent in the physical and chemical assessment of the degree of technogenic pollution, and in combination with the latter, it brings closer the solution of the problem of environmental quality management. Adequate monitoring of ecosystems is based on the use of functional (for example, bio-productivity, ows of substances) and structural (composition of communities, number of species, their biomass) biological parameters (Gilyarov 1986).…”

Fish and fish tissue are effective bioindicators due to their sensitivity to pollution and are frequently used for assessing aquatic ecosystem health. Establishing baseline metal concentrations in freshwater fish tissues within aquatic ecosystems is important prior to establishing industrial activities to help determine potential future industrial impacts. Historically, North-Eastern European Russia has been an area with relatively low levels of industrial development and is still in pristine condition. In this region the noise to background ratio for industrial contaminants may be disproportionately high. This study measured baseline metal concentrations in freshwater fish tissues collected from three study sites (Bolshoi Patok, Maly Patok and Kara River) in North-Eastern European Russia as bioindicators for overall aquatic ecosystem health. Seven fish species including European Grayling, Arctic Char, Whitefish, Perch, Pike, Roach, and Peled over a five-year period between 2000 to 2005. Fish tissue samples were analyzed for Copper (Cu), Lead (Pb), Cadmium (Cd), and Zinc (Zn) metal concentrations. Metal concentrations measured in fish tissues in this study compared favourably to remote sites in Alaska in the US and Slovenia. Despite small variation between sampling sites, metal concentrations were relatively low and considered in pristine condition. Metal concentrations measured in fish tissues in this study represent baseline conditions which will be important to compare against using monitoring programs should the region experience future industrial development.
