dc.description.abstractHistorical accumulation of heavy metals in landfills has caused an increased leaching in groundwater all around the world. The elevated concentration of heavy metals in groundwater can cause environmental problems in most of the surrounding areas. The main objectives of this study are to determine the concentration of metal ions (Ni, Cr and Cd) in the groundwater of Pulau Burung landfill located within Byram Forest Reserve at 5º 24'N, 100º 24'E in Penang, Malaysia, to study the biosorption of Trichoderma sp. on nickel, cadmium and chromium in the contaminated groundwater, identify the changes in the functional groups of Trichoderma sp. before and after treatment and its applicability on adsorption isotherms models to determine its biosorption capacity. In this research, monthly samplings of the groundwater within the site were conducted from May to December 2008 and analyzed for the concentrations of heavy metals using AAS. Studies on the fungal, Trichoderma sp. on its cell structure and morphology were performed using Transmission Electron Microscope (TEM) and Scanning Electron Microscope (SEM). Biosorption studies on Ni, Cd, and Cr by fungi (Trichoderma sp.) using Freundlich and Langmuir adsorption isotherms together with the treatment on raw contaminated groundwater from PBLS is used to assess its ability to adsorb the heavy metals. Finally, biosorption using Trichoderma sp. is used to treat the raw contaminated groundwater and a Fourier Transform Infra Red Test on the fungus was carried out before and after the treatment of the groundwater to identify the functional groups. Findings through the analysis of the groundwater showed presence of pollutants containing heavy metals with higher accumulation during mid year from May till August 2008 and started to plummet slowly until the end of the year.en_US
