The Impact

The aim. The aim of the work was to study the indicators of spermatogenesis in the lake frog, Pelophylax ridibundus (Pallas, 1771), in the zone of the influence of emissions from the Burshtyn Thermal Power Plant (TPP). Materials and methods. Urinal sperm and testes samples were taken from male frogs under conditions of anthropogenic pollution (Burshtyn industrial area). Such parameters as sperm concentration in ejaculate, the number of live spermatozoa, total amount of actively mobile forms, and percentage of spermatozoa with progressive motion were determined by calculations in the hemocytometer. Testis samples were processed for routine histological method. The diameter of seminiferous tubules and histological abnormalities were studied. Results. Studies have revealed that near the Burshtyn TPP industrial site, the sperm concentration in the sperm sample and the total number of motile spermatozoa of the lake frogs significantly decreased. The number of dead spermatozoa increases. Amphibians from polluted sites had histological abnormalities in testes such as dilation of the seminiferous tubules with sparse sperm. At the same time, the diameter of the seminiferous tubules in the animals from polluted site significantly decreased. Conclusions. The impact of the emissions from the Burshtyn thermal power plant has an expressive reprotoxic effect that is manifested by depressive changes in testes tissue and gametes. The reproductive system of the lake frog is quite sensitive to environmental pollution. Sperm parameters and histological changes in testes are informative biomarkers and can be used for bioindication of technogenically transformed territories

The study involves evaluation of quality of groundwater and soil near the Thermal power plant located in Udupi District, Karnataka, India based on seasonal variation. 24 samples of ground water and soil were collected during Pre-Monsoon, Post- Monsoon and Monsoon Seasons from the places which are surrounding the Thermal Power plant. Collected Ground water samples were tested for detection of various heavy metal concentrations such as Ni, Fe, Mn, Cr, and Pb and soil samples were detected for Ni, Fe, Mn, Cr, Pb, Cd and Co. Collected soil samples were sieved according to different Standard sieve size. After sieving, soil samples were digested using tri-acids (Nitric Acid, Hydrogen peroxide and Concentrated Hydrochloric acid). Both Ground water and Soil samples were analysed for heavy metal contamination by using Atomic Absorptive Spectrometry. From the results obtained for Pre-Monsoon, Post-Monsoon and Monsoon Season it showed that concentration of heavy metals in the samples were exceeding the permissible limit prescribed by WHO and BIS. Hence preliminary treatment should be done before discharging in to Ash ponds.

The Impact

The main sources of thermal energy for the heat supply of cities and settlements are fuel-based thermal power plants and boilers. The article provides an analysis of the energy balance of a power plant in connection with the need to minimize the cost of fuel and electricity for heat supply. New analytical expressions comprehensively characterizing the efficiency of a power plant are developed. The analytical assessment of the impact of energy costs for the boiler needs on the energy balance of thermal power plant is made; methods for constructing schemes of the energy balance of thermal power plant and assessment of fuel efficiency in the boiler are designed. Attention is paid to errors arising from the use of the calculated values of air suction in the gas path of the boiler, and not the actual ones. Therefore, it is proposed to change the method of measuring heat loss with flue gases in order to eliminate or reduce the effect of air suction on the measurement results, taking into account the part of the flue gas heat received by the air in the air heater and returned to the boiler through the burner. The methods increasing accuracy of calculations of energy efficiency of the technological processes which are key in the centralized heat supply of the cities and settlements are developed.
