description Measurement CO2 fluxes from antropic source: Municipal final disposition site, Gualeguaychú, Entre Ríos. Direct measurement of surface CO2 emissions (CO2 fluxes) represents an effective tool to estimate the contribution of greenhouse gases to atmosphere from individual sources. In this work, the authors report the first results of surface CO2 fluxes from a waste municipal final disposition site in Gualeguaychú, Entre Ríos. It was applied the accumulation chamber method which was calibrated in laboratory before the land measurements. Three surveys at different scale sample were carried out (25, 50 y 100 m). Soil CO2 fluxes range from 5 to 331 g/m2 day. Using statistical analysis three different populations were distinguished (background soil gases and anomalous values) and the total gas emissions from the site was calculated. The soil CO2, CH4, O2 and N2 concentrations, the time and depth emplacement of waste, the materials no compacted and meteorological conditions, suggest that the site had passed all waste biodegradation phases. Actually, it could be at final stage. The δ13C of soil CO2 (-34,2‰ y -17,6‰) as the dissolved inorganic carbon (DIC) and the δ13C of DIC (-12‰ a -0,6‰) of groundwater samples show that actual process oscillate between aerobic and anaerobic oxidation phases.
