    Assessment of methane emission and oxidation at Air Hitam Landfill site cover soil in wet tropical climate
    (Springer, 2013) Mohammed F. M. Abushammala; Noor Ezlin Ahmad Basri; Rahmah Elfithri
    Methane (CH4) emissions and oxidation were measured at the Air Hitam sanitary landfill in Malaysia and were modeled using the Intergovernmental Panel on Climate Change waste model to estimate the CH4 generation rate constant, k. The emissions were measured at several locations using a fabricated static flux chamber. A combination of gas concentrations in soil profiles and surface CH4 and carbon dioxide (CO2) emissions at four monitoring locations were used to estimate the CH4 oxidation capacity. The temporal variations in CH4 and CO2 emissions were also investigated in this study.

    Empirical gas emission and oxidation measurement at cover soil of dumping site: example from Malaysia
    (Springer, 2013) Mohammed F. M. Abushammala; Noor Ezlin Ahmad Basri; Hassan Basri; Abdul Amir H. Kadhum; Ahmed Hussein El-Shafie
    Methane (CH4) is one of the most relevant greenhouse gases and it has a global warming potential 25 times greater than that of carbon dioxide (CO2), risking human health and the environment. Microbial CH4 oxidation in landfill cover soils may constitute a means of controlling CH4 emissions. The study was intended to quantify CH4 and CO2 emissions rates at the Sungai Sedu open dumping landfill during the dry season, characterize their spatial and temporal variations, and measure the CH4 oxidation associated with the landfill cover soil using a homemade static flux chamber.
