Abstract
Cities are major contributors to greenhouse gas emissions due to a high density of urbanization, numerous industrial centers, concentrated breeding of chickens, pigs and intensive agricultural activity. These anthropic GHG sources overlap to the endogenous sources of methane related to peat degradation hosted in the test site, Pliocene and Holocene sediments or to dispersion from buried methane deposits that characterize the outermost, NE-verging fronts of the Northern Apennines. Demonstrative activities were carried out in an area with a high density of abandoned wells used before 1962 for the extraction of methane, whose emission contributions are currently unknown. Air quality monitoring and soil gas monitoring system for methane and radon gas, at 10cm and 1m depth was the main purpose of this paper. Measurements have been taken for radon concentrations with a Durridge RAD7 Company, Inc., USA instrument. It was used for atmosphere and soil gas monitoring system three Biogas ETG (Etg Risorse e Tecnologia, Italy) instruments, with a nondispersive infrared sensor (NDIR) CH4 gas sensor. The measurements started in March 2016 and continued in July-August-September 2016, to determine methane and radon gas concentrations, their distribution and to understand the relationship among gases and atmospheric conditions. What distinguishes this study from those conducted at other gas storage site is the methodology used, the monitoring system was done in the same time in the atmosphere and at different depths into the soil (10 cm and 1m depth) to understand the differences of methane gas concentration between atmosphere and soil.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
