bioindication

The work investigated the effect of encapsulated mineral fertilizers on the growth and development of plants for 45 days. As a mineral fertilizer, nitroammophoska was used, which was encapsulated by a shell of different compositions: sample KD1 – a mixture of polystyrene, lignin, and carbon; sample KD2 – a mixture of polystyrene, lignin, and zeolite. The bioindication method was used to determine the effect of encapsulated mineral fertilizers on plant growth kinetics.

These studies were conducted to test the hypothesis that sewage sludge from Lviv municipal wastewater treatment plants (LMWWTP) facilities can be used to create a substrate that can be used for biological reclamation. The qualitative composition of sewage sludge from Lviv municipal wastewater treatment plants is determined. The study of bioindication of a mixture of sludge with dark gray soil was carried out in two stages, which showed a significant difference between fresh and settled sludge. Possible conditions for the use of sludge in the substrate are presented.

The aim of the work is to improve the method and means of multispectral measurement of the content of unsuitable chemical plant protection products in aqueous media using bioindication on phytoplankton. The article analyzes the errors of indirect measurements and the reliability of the control of the concentration of pesticides using the developed means of environmental monitoring of integral parameters of pollution of water bodies

Monitoring of the environmental condition of the natural surface water bodies in northern and northeastern parts of Lviv region was conducted. The investigated water bodies belong to the Western Bug river basin and Baltic Sea basin. The monitoring was conducted by using bioindication, microbiological methods and physicochemical analysis. The most polluted rivers and sources of pollution were defined. Solutions to the environmental pollution problem were proposed. Здійснено моніторинг екологічного стану природних водойм північної та північно- східної частин Львівської області.

In this article the environmental monitoring of the natural water bodies based on qualitative and quantitative analysis of bioindicative organisms were conducted. Approbation of the sampling methods, techniques and laboratory analysis of biological objects from natural ecosystems were carried out. The next biological objects have been analyzed: periphyton from rocky and stony coasts, algae and meiofaunal organisms (Nematoda, Harpacticoida, Cladocera, Rotifera), and macrobenthos freshwater river-living organisms. Main influences and distribution dependences were found.

The purpose of this work is to improve the ecological state of water bodies and coastal area of the “Enerhoharant” LLC company by implementing a series of environmental measures based on research of their ecosystems and environmental-economic assessment that will enable largely to solve the problem of optimal use of natural resources for the recreational purposes.
