Development of methods and hardware for monitoring of water ecosystems state

Article preview

A complex of express optical methods and apparatuses has been developed that make it possible to measure a wide class of hydrobiological, hydrophysical and hydrochemical characteristics of water bodies. An original complex of sorption-spectroscopic techniques for determination of toxicants in natural waters using methods of solid phase spectroscopy (diffuse reflection spectroscopy, luminescence spectroscopy, solid phase spectrophotometry), atomic spectroscopy (atomic absorption spectroscopy and atomic emission spectroscopy with luminescence spectroscopy spectroscopy), atomic spectroscopy (atomic absorption spectroscopy and atomic emission spectroscopy with luminescence spectroscopy spectroscopy) and various other methods were developed. SR), chromatographic (ion chromatography) methods, On the basis of such multidisciplinary systems of rapid assessment of ecological condition and functioning of ecosystems, quality of surface waters the analytical, hardware and information support for monitoring and control of the quality of the natural environment was created.

Investigations of correlations between phytoplankton physiological state and fluorescence response using its maximum and stationary parameters

Article preview

The effect of heavy metal salts on the maximum and steady-state fluorescence intensity of algae was investigated. Different influence of copper, manganese and cobalt ions on these parameters was shown. The photosynthetic activity coefficient (PAC) calculated on the basis of these parameters correlates with the concentration of heavy metal salts and physiological state of algae. It was found that natural phytoplankton in polluted areas has a lower CFA value than in ecologically clean areas.
