“…A general characteristic of bioestimation was given in [5] (Table 1). This paper gives the main groups and individual factors that affect the process of water puri fication; lists the bioestimators, i.e., the hydrobiologi cal characteristics changes in which indicate to the impact of appropriate factor; the last column gives typical rehabilitation recommendations used to develop necessary measures in accordance with the revealed disturbances in the process.…”

“…Diagnos tic studies should be carried out at the stage of quality formation with the aim to timely interfere in the pathological process, prevent the deterioration of quality characteristics, optimize the restoration mea sures-all those problems can be solved with the use of bioestimation. A generalized characteristic of bioesti mation, a new method for the control of water purifi cation, is given in [5] along with its comparison with bioindication, the well known method of water qual ity control. The process of biotic water self purification in a natural water body, as well as the biological treatment of wastewaters is governed by numerous physical, chemical, or mechanical factors, but it is implemented aquatic biota, primarily, organotrophic bacteria.…”

Examples are given of the application of bioestimation-a conceptually new hydrobiological method used to control the process of water quality formation. This paper is the continuation of the paper "Bioestimation: A New Method for the Control of Water Self Purification Process and Its Comparison with Bioindication". The experience in the use of bioestimation in water bodies with different use type, size, salin ity, flowage, and geographic position confirmed its universal character, information value, promptness, and the possibility to limit the volume of sample to be sent to 10-20 cm 3 , thus simplifying the field works. Each significant factor, which affects the self purification process, is identified independently, since the bioestima tors reflecting it are biotically independent; their number varies depending only on changes in the environ mental factors that are external with respect to the community of environmental factors. Bioestimation shows prognostic properties, since it makes it possible to prevent water quality deterioration and to restore the nor mal course of water self purification at the stage of its quality formation. The use of bioestimation will extend the positive anthropogenic impact on water bodies.

“…Accumulation of heavy metals in organisms of different taxonomic groups, as well as behavioral responses of hydrobionts to the presence of heavy metal ions, have been quite well investigated (Vasil'kov 2005;Klishko et al 2007;Mosharov et al 2009). Years of field and experimental research showed that toxic heavy metals, such as cadmium, lead, mercury, copper and zinc are among the most significant pollution actors in marine environments and should be a priority for further investigation (Vasil'kov 2005;Nikitina et al 2009;Rudneva 1995). Ecologica Montenegrina 14: 109-118 (2017) This journal is available online at: www.biotaxa.org/em Being one of the enzyme-substrate components of the internal biophysical cycles, bioluminescence system of the plankton can be affected by exposure to environmental toxicants (Tokarev et al 2016).…”

Investigations were conducted in the Department of biophysical ecology of Kovalevsky IMBR of RAS in September - October of 2013 and 2015. The body length of the gathered for experiments ctenophores was 35 – 40 mm. Characteristics of the ctenophores light emission were studied under the mechanical and chemical stimulations, with the usage of laboratory complex “Svet”. The following HM salts: Cu2S04, ZnCl2, PbCl2 and HgCl2 in different concentrations were used in our experiments. The just-caught samples, contained in the clean marine water were used as a control. The exposition time was 1, 3 and 24 hours under the temperature of 21 ± 2°C. The investigations results have shown considerable variability of the ctenophore luminosity characteristics in dependence of metal concentration and exposition duration. It was stated that minimal concentrations of cooper, zinc and mercury stimulates ctenophores bioluminescence and the high ones inhibit. The alien ctenophore luminescence inhibition was registered under the lead activity under all investigated concentrations. We can place investigated metals as following: Zn < Cu < Hg < Pb, according to the force of the toxic influence on the ctenophore bioluminescence. Thus, alien ctenophore bioluminescence parameters can serve as a sensitive express-indicator of the resistance degree to the heavy metals impact and be the expressive index of the marine environment regional pollution.
