“…2). This is a significant factor in the dynamic CH 4 balance at a site and is often neglected in assessment studies (e.g., Peer et al, 1993). A reduction of 1% (v/v) in CH 4 concentration (assuming in this case the volume and pressure of the landfill remains constant) would require 14 g CH 4 m À3 moving out of the gas-filled porosity, or 6 kg CH 4 for a 20 · 20 · 10 m cell (assuming a gas-filled porosity of 0.20).…”

“…There are some reports on quantification of methane flux from landfills (Jones and Nedwell 1993;Nozheikov et al 1993). The estimation in these reports on the global contribution of landfill methane has been based on calculations of deposited amounts of waste and their estimated degradation rates (Peer et al 1993). Bhide (1998) had reported total methane flux from Indian cities as 0.33 Tg/y.…”

In this study, an attempt has been made to study methane flux and quantification of heavy metals from Municipal Solid Waste (MSW) landfill areas of selected cities in India. During the period of study, the average value of methane flux was estimated from these landfill areas varied from 146-454 mg/m2/h. Methane emission from landfill is of serious environmental global concern as it accounts for approximately 15 percentages of current Greenhouse gas emissions. It has been estimated that methane emission, from landfill areas in the world, in next two decades would be same as that what is emitted from paddy fields presently. Besides, the estimation of methane flux, quantification of some heavy metals was conducted to analyse the suitability of using MSW as compost. The average values for metals were observed to be both within the range of USEPA and Indian standards for MSW disposal in landfill areas and to be used as compost respectively.

“…Emissions from landfills are affected by numerous environmental and technical variables, including temperature, soil moisture, and CH 4 concentration within the landfill; the amount, organic composition, and age of the waste; and the thickness of the overlying layer. (Bogner and Spokas, 1993;Peer et al, 1993;Czepiel et al, 1996). Emissions from landfills, wastewater, and manure collection lagoons can be reduced by trapping the methane before it is released to the atmosphere, and either flaring it or using it as an energy source.…”

Methane (CH 4 ) is the most abundant organic trace gas in the atmosphere. In the distant past, variations in natural sources of methane were responsible for trends in atmospheric methane levels recorded in ice cores. Since the 1700s, rapidly growing human activities, particularly in the areas of agriculture, fossil fuel use, and waste disposal, have more than doubled methane emissions. Atmospheric methane concentrations have increased by a factor of 2 -3 in response to this increase, and continue to rise. These increasing concentrations have raised concern due to their potential effects on atmospheric chemistry and climate. Methane is important to both tropospheric and stratospheric chemistry, significantly affecting levels of ozone, water vapor, the hydroxyl radical, and numerous other compounds. In addition, methane is currently the second most important greenhouse gas emitted from human activities. On a per molecule basis, it is much more effective a greenhouse gas than additional CO 2 . In this review, we examine past trends in the concentration of methane in the atmosphere, the sources and sinks that determine its growth rate, and the factors that will affect its growth rate in the future. We also present current understanding of the effects of methane on atmospheric chemistry, and examine the direct and indirect impacts of atmospheric methane on climate. D
