Approbation data of the innovative CLEANSOIL technology of soil purification after oil pollution are given. Drainage pipes filled with an adsorbent with microorganisms placed in the soil are used. It is revealed that the content of hydrocarbons under the technological constructions (metal columns and reservoirs) rises in comparison with the open oil-polluted areas. It is shown that the oil is destroyed quicker under the constructions versus in the open areas. The microorganisms better assimilate the n-alkanes with C14 chains than the C32–40 hydrocarbons. The application of a combined technology based on the sorption and reduction of the hydrocarbons by microorganisms makes it possible to quickly reduce the soil pollution by oil products without the soil cover’s disturbance.  相似文献

During summer and autumn of 2008–2010 in the north and middle taiga, measurements of methane emissions from different types of wetland landscapes in Khanty-Mansi and Yamalo-Nenets Autonomous Okrugs were made by the static chamber method. Total methane emission from West-Siberian northern and middle taiga mires is estimated at 550 and 530 kt C-CH4 per year.  相似文献

The methane emission from typical bog landscapes of the West Siberian subtaiga was studied in the summer-autumn of 2007?C2010. The lowest specific fluxes (the median value is 0.08 mg C-CH4/m2 per h) were recorded from ryams (raised bogs with dwarf shrub-sphagnum associations). From the ridges of the ridge-pool complexes, the fluxes were estimated at 0.49 mg C-CH4/m2 per h; from the oligotrophic hollows, eutrophic bogs, floating lake mats, and mesotrophic quaking bogs, they were estimated at 2.68, 3.36, 4.53, and 4.98 mg C-CH4/m2 per h, respectively. The maximal flux was determined from the lakes (the median is 17.98 mg C-CH4/m2 per h). The regional assessment of the methane flux from the bogs of Western Siberia (2.93 Tg C-CH4/yr) was obtained on the basis of the authors?? and literature data.  相似文献
