(N=27) were analyzed. The test group of animals (N=17) were taken in the region contaminated by the power plants of Kosovo in Obiliq, while the snails of control group were from another region of Kosovo – Ferizaj, which is unaffected by industrial pollution and is far away from power plants. The investigation results have shown that the concentration of the cholesterol and total protein in the hemolyph of snails of control group were significantly higher P<0.001. Whereas, concentration of glucose was also significantly higher P<0.01 but with a lower rate than two abovementioned parameters compared with the snails of the polluted region. Statistical results were calculated using software MINITAB 16. The investigation shows that the Garden snail can serve as bio-indicator, whereas the changing of the hemolymph chemistry as marker for the biochemical indication of the environmental pollution effects. Keywords: Helix pomatia L., hemolymh, glucose, cholesterol, total proteins Introduction Environmental pollution in Kosovo has arisen at high level. The causes of this pollution are different, as: uncontrolled coal exploitation for Power Plants, mineral resources of Pb, Zn, Cr, obsolete technology, inadequate and unprofessional use of agrochemicals, food additives, dense traffic of old cars with incomplete combustion of fuel, without catalyzators, which release toxic gases, aerosols, cancerogenous benzopyren, large and uncontrolled urbanization, lack of water treatment plants, lack of sanitary landfills, etc. (Adrović F., 1997). Due to its proximity to the Power Plants and other above-mentioned problems, Pristina region is considered among the most polluted areas in Kosovo. Therefore, compared to other European countries, Kosovo ranks in the tenth’s position of the countries with the higher degree of pollution (WHO, 2002). In economic and mining aspect, coal, which represents one of the main natural fuel for generating electricity in Kosovo dominates compared to other minerals (98%). According a pre-calculation, lignite reserves in Kosovo brought about 14.3 billion tons, enough to produce electricity for the next 100 years, (Zeqiri, 1984). When the lignite of medium quality burned in power plants with 200MW capacity and 6300 tons of coal daily consumption, if the electro-filters work normally, every day in the atmosphere released 382 tons of S0 2 , 60 tons of NOx, 1.4 tons of CO as well as large quantities of ash particle (250 tons within 24 h, especially at night and weekends
