Heavy metal concentrations in deep-sea sediments collected from Kuril Basin (Sea of Okhotsk) and Kuril-Kamchatka Trench area were analyzed. For the Kuril Basin, a geochemical natural background of these elements was identified based on a dated core. The results showed enrichment by heavy metals due to natural factors in the study area. All heavy metals showed a low ecological risk; thus, the potential ecological risk of the study area was also low.

The review considers the complex of non-radiation factors that could affect the liquidators of the Chernobyl accident: the demographic, social and professional group heterogeneity to warrant differentiation of risk, the effects of heavy metals, 'hot particles', chemicals, psychogenic stress, social dislocation in the post-perestroika period, alcohol abuse, smoking, and the effect of screening. All these factors tend to have a significant intensity, unlike the radiation exposure for the majority of subjects. It is concluded that the increased frequency and severity of some large socially significant pathologies in contingent liquidators may be due to a unique set of predominantly non-radiation factors associated, however, with a particular radiation accident.

The control of exposure to welding fumes is increasing importance in promoting a healthy, safe and productive work environment. This study is a case-control design, random study was conducted among welder (56 subjects) and non welder (39 subjects) with more than 1 years experience in the same job task in an automotive parts manufactory within the industrial area at Cikarang in 2013. All subjects were completed physical examination, informed consent and questionnaire. Blood heavy metals were determined by Inductively-Coupled Plasma Mass Spectrometry (ICP-MS). Whole blood iron, manganese, chromium and lead in welder were higher than non-welder, but not different for aluminum, nickel and cadmium. In welder, chromium and manganese correlated with smoking status, cadmium correlated with age and smoking status. In multivariate analysis, wholeblood cadmium correlates with age and smoking status.

Heavy metal pollution is one of the most important environmental problems today. Biosorption is an innovative tech- nology that employs biological materials to accumulate heavy metals from waste water through metabolic process or physicochemi- cal pathways of uptake. Even though several physical and chemical methods are available for removal of heavy metals, currently many biological materials such as bacteria, algae, yeasts and fungi have been widely used due to their good performance, low cost and large quantity of availability. The aim of the present study is to explore the biosorption of toxic heavy metals, Cr(VI), Cr(III), Pb(II) and Cd(II) by algal biomass obtained from algae Sargassum wightii (brown) and Caulerpa racemosa (green). Biosorption of algal biomass was found to be biomass concentration- and pH-dependent, while the maximal biosorption was found at pH 5.0 and with the metal concentration of 100 mgL-1 . Sargassum wightii showed the maximal metal biosorption at the biomass concentration of 25 g L-1 , followed by Caulerpa racemosa with the maximal biosorption at 30 gL-1 . Sargassum wightii showed 78% biosorption of Cr(VI), Cr(III), Pb(II) and Cd(II) ions. Caulerpa racemosa exhibited 85% biosorption of Cd(II) and Cr(VI), and 50% biosorption of Cr(III) and Pb(II). The results of our study suggest that seaweed biomass can be used efficiently for biosorption of heavy metals.

ABSTRACT: Microelements were measured in the biogenic detritus that accumulated over 8 months in the aquatic microcosms with Viviparus viviparus and Ceratophyllum demersum. Their concentrations were measured using atomic absorption spectroscopy (AAS). The concentrations decreased in the order: Fe > Mn > Zn > Cu > Pb > As > Co > Cd > Cr. Following the addition of the metals (Co, Fe, Mn, Zn, Cu, Cd, Cr) into the water of the microcosm, those metals were found in the sedimented detritus at concentrations higher than in the control. The most pronounced increase was found for Co (the increase by the factor of over 13), and for Cr (the increase by the factor of over 100). The new data confirm the recent theory of the polyfunctional role of the biota in water quality control and water self-purification (Doklady Biological Sciences, 2004, Vol. 396, p. 206-211), and contribute to the scientific basis for remediation of aquatic ecosystems.

Библиогр. 39 назв. Изучали протекающее во времени снижение концентраций тяжелых металлов (Pb, Cd, Zn, Cu) в воде экспериментальных экосистем (микрокосмов) с элодеей Elodea canadensis. Концентрации тяжелых металлов (Pb, Cd, Zn, Cu) в воде экспериментальных микрокосмов измеряли методом инверсионной вольтамперометрии. В микрокосмах инкубировали элодею Elodea canadensis. Концентрация свинца, кадмия и других металлов после инкубации с элодеей значительно уменьшилась. Впервые получены убедительные доказательства того, что измеряемые этим методом концентрации металлов (Pb, Cd, Zn, Cu) в микрокосмах с макрофитами Elodea canadensis снижались значительно быстрее, чем в контрольных микрокосмах без макрофитов, что доказывает новый аспект фиторемедиационного потенциала элодеи.

The synecological approach to the problem of eutrophication. - Doklady Biological Sciences, Vol. 381, 2001, p. 559–562. http://scipeople.com/uploads/materials/4389/Danbio6_2001v381n5.E.eutrophication.pdf [Translated from Doklady Akademii Nauk (DAN), Vol. 381, No. 5, 2001, p. 709–712. Russian Text] ISSN 0012-4966. DOI 10.1023/A:1013378505630. The author proposed a new solution to the problem of eutrophication. This new vision is based on a synecological approach. In the paper, the author proposes a new two-component solution in order to protect the aquatic ecosystem from eutrophication. First, it is essential to reduce the input of nutrients. Second, it is equally important to reduce the input of the pollutants which weaken the potential of the ecosystem for removing the biomass of phytoplankton by filter-feeders. Those pollutants include surfactants, detergents, and some other compounds. Because synecology is one of key approaches in our analysis, this concept of counteracting eutrophication can be called a synecological solution to the problem. New experimental results: the detergent ‘Fairy’ inhibited the filtration rate of mussels Mytilus galloprovincialis; this complements the earlier data of the author on how detergents affect filter-feeders. --KEY WORDS: danger, chemical pollution, hazards, xenobiotics, synthetic, surface-active agents, surfactants, laundry detergents, heavy metals, mixtures, eutrophication, water filtration, clearance rate, invertebrates, pellets, filter-feeders, suspension feeders, bivalves, mollusks, rotifers, mussels, Mytilus, edulis, galloprovincialis, Crassostrea gigas, Dreissena, Unio, phytoplankton, zooplankton, algae, Daphnia, aquatic, ecosystems, sustainable, use, water resources, environmental safety, control, pollution, new, approach, solving, man-made reservoirs. --Остроумов С.А. Синэкологические основы решения проблемы эвтрофирования // Доклады академии наук (ДАН). 2001. том 381. № 5. С.709-712. Видение автором нового решения проблемы эвтрофирования основывается на синэкологическом подходе. Автор предлагает новый подход - двухкомпонентное решение в целях защиты водных экосистем от эвтрофирования. Оба компонента в равной степени важны и должны реализовываться (применяться на практике) одновременно. Во-первых, необходимо снизить поступление биогенов. Во-вторых, равным образом важно снизить поступление поллютантов, которые ослабляют потенциальную способность экосистем удалять биомассу фитопланктона благодаря активности фильтраторов. Эти поллютанты включают в себя поверхностно-активные вещества, детергенты и некоторые другие. Детергент Fairy ингибировал фильтрационную активность мидий Mytilus galloprovincialis, что дополняет ранее полученные данные автора о том, как детергенты воздействуют на фильтраторов. Поскольку синэкология – один из ключевых подходов в нашем анализе проблемы, эта концепция противодействия эвтрофирования может быть названа синэкологическим решением проблемы. --Ключевые слова: опасность химического загрязнения, ксенобиотики, синтетические поверхностно-активные вещества (ПАВ), детергенты, синтетические моющие средства (СМС), тяжелые металлы, смесевые препараты, эвтрофикация, фильтрация воды, беспозвоночные, пеллеты, фильтраторы, двустворчатые моллюски, коловратки, мидии, Mytilus edulis, Mytilus galloprovincialis, Сrassostrea gigas, Dreissena, Unio, фитопланктон, зоопланктон, Daphnia, водные экосистемы, устойчивое использование водных ресурсов, экологическая безопасность, борьба с загрязнением и эвтрофикацией, новый подход к решению проблемы.
