A mercury-cell chlor-alkali plant operated 50 years in Ka?tela Bay (situated in the middle of eastern Adriatic coast) near the town of Split. Even after 28 years the abundant cell house is still a hazardous source of the total gaseous mercury. Measured concentrations in the air (2.1 ? 9.6 ?g m-3) could possibly present Hg-pollution of 9 km distant source of Jadro River. This source is used as a drinking water supply for the town of Split. The aim of the work was to find how far mercury is transported. Total mercur...

The increased vulnerability of the aquatic landscapes of Subarctic of the European part of Russia to anthropogenic impact is a consequence of natural conditions and its geographical location. In this regard, the study of small rivers and their catchments which are remote from the direct influence of the industrial and residential zones is of particular interest to researchers, since they can be considered as background areas of the Subarctic. One of these rivers is Kyanda flowing into the Onega Bay of the White Se...

The article presents the materials of long-term research conducted from 2004, in the mouth area of the Northern Dvina River. The program of researches included determination of concentrations of mercury in the water, covering about 150 km of the river length. We also analyzed such parameters of water as pH, Eh, oxygen content, salinity. A long observation period allowed us to trace the peculiarities of the changes of mercury content in water, which was the aim of the present work. Previously the authors determined...

The adsorption excretion of Hg, As, and Cu ions from aqueous solutions at 22±0.5°C on zeolite (Sokirnitskoe deposit, Transcarpathia) and smectite clay (Kamalinskoye deposit, Krasnoyarsk region) were studied. The adsorption processes were studied in the static regime at pH?2. Parameters such as, the time of equilibrium establishment, the ratio "sorbent - solution" were selected experimentally. All samples were filtered through a 0.2 ?m membrane using syringes. The samples for Hg were selected strictly in teflon dis...
