 abstract={The results of investigation on the amount and chemical composition of biogas emitted from bottom sediments of polluted Dzierżno Duże dam reservoir have been presented. The bottom sediments could be a resource of considerable quantity of biogas, e.g. methane. The dilution of methane in water is similar to that of oxygen. The presence of methane dissolved in the water deteriorates environmental conditions. The quantity of biogas depending on temperature ranged from 2 to 12 dm3/m2*d. The biggest singular grow exist in the water temperature 10-15°C. Chemical composition for biogas is dependent on the temperature. Along with the water temperature growth from 7 to 24°C, participation of methane in the biogas increased from 73% to 85%, and the participation of nitrogen from 3.9% to 22.47%. The participation of carbon dioxide decreased from 22% to 4.5%. The heterogeneous process of biogas emission arc running in the kinetic and diffusion area is dependent on temperature. In the low temperature the progress of the process is controlled by the speed of biochemical reaction. The progress of the diffusion process grows in a high temperature, and in the range of 15-24° C the processes is controlled by diffusion of substrates and products of reaction.},
