Comparative Flux Estimation Study of Methane and Carbon Dioxide between Unmanaged and Managed Landfill Sites of Udaipur, Rajasthan

Priyanka Dwivedi, Nidhi Rai and Uduebor Micheal*

Landfill sites are grabbing the attention due to the noxious emission of green house gases (GHG’s) into theatmosphere. This is anthropogenic emission source holds third position in the world. The present emission flux studyof methane and carbon dioxide was done in two landfill sites situated outside the city of Udaipur, Rajasthan. Theextensive field monitoring was done for a period of two years i.e. from Jan.2018 to Dec.2019 at Titardi and Balechhalandfill sites by using protocol as mentioned in IPCC, 2006 guidelines for static flux chamber method. The chamberwas connected with respective CO2 and CH4 analyzers for direct measurement that records in concentration (ppm)over time (sec.) on heterogeneous surface area of these two sites. The emissions flux rate was ranging not beignored so, needs proper attention either to mitigate its detrimental effects or utilized as a source of energy for othersectors. No one had chosen these two sites (BLS & TLS) earlier for the measurement of GHG fluxes so, forms asthe first report. This intensive field study will help in diminishing vulnerabilities in the estimation of CO2 and CH4fluxes. The leachate analysis is needed to be done further for assessing the environmental threats as a goodresearch scope in these sites.
