Middle Caspian influence on water quality of North Caspian

The distribution of heavy metals in water, sediments and pore waters of the North and Middle Caspian has been analyzed. It is shown that the development of recovery processes at border bottom sediments - bottom water near the continental slope of the Middle Caspian Sea could lead to removal of heavy metals in the water body and may cause secondary pollution of the North Caspian. This is confirmed by the distribution of Mn in free and pore waters of the Northern and Middle Caspian within the period 1994-1995.

Keywords: Caspian Sea, heavy metals, pore and gravitationalwater, secondary pollution

Qualimetry methods for laboratory results analysis

Spread in quantitative characteristics of water quality often exceeds their average value, with measurement error being comparable with the scatter, and the error caused by insufficient sample size being comparable with accuracy. Under these circumstances, interpretation of the results of laboratory research requires the use of such methods asqualimetry, which include intervalnonparametric and parametric estimation based on the mathematical tool of the theory of tolerance intervals. Method for probability estimation of controlled parameters exceedance for water risk assessment has been developed. The method has been tested in order to fix an acceptable level of risk, and to establish trust-based business relations on water servicemarket. Recommendations to limit the uncertainty of the results of water quality assessmentmanagement have been made.

Cu2+ and Ni2+ sorption by anion exchange resins based on epoxide derivates of aromatic amines and polyethyleneimines

Sorption of Cu2+ and Ni2+ ions has been studied by classical polarography method by polyfunctional anion exchangers based on epoxy derivatives of aromatic amines and polyethyleneimine. They are proved to have high kinetic and sorption characteristics, and are superior in absorptive capacity. The removal efficiency of Cu2+ and Ni2+ ions from sulfate solutions containing 0,1 g /l of metal is 92-99%.

Keywords: anion exchangers, copper (II)ions, nickel (II) ions, sorption

Zooplankton changes in the long profile of Hrazdan river, Armenia

The changes in zooplankton of Hrazdanriver in the long profile, within the period May – October 2006 at 3 stations have been studied. There are 25 species of invertebrates, of which two species of rotifers, 13 of cladocerans and 10 of copepods. The highest species diversity of zooplankton was observed from river’s outletdown to the city Yerevan, the mouth area was characterized by poor species diversity of zooplankton, biomass uniformity as well as an increase in the proportion of invertebrates, producing food from the surface of the substrate.The main dominating factors of zooplankton have been determined.

Artificial aquatic ecosystems as elements of environmental design

In the production of the human environment, as a rule, most acutely jars with the natural environment. It is advisable to introduce the term "ecological design of production" and detailed elaboration of this aspect. Artificial aquatic ecosystems - bioponds may serve as one of the objects of ecological design. At the same time bioponds cannot be only an aesthetic function of objects of ecological design, but also directly improve process performance.
