HEAVY METALS IN WATER AND SEDIMENT FROM LIWAGU RIVER AND MANSAHABAN RIVER AT RANAU SABAH

The Liwagu River is one of the most reliable river systems in Ranau which had experienced a mudflows event due to massive landslide of Mount Kinabalu. The aim of this study is to determine the water quality and compare the level of heavy metals in water and sediment of the Liwagu River and a non-impacted mudflows of Mansahaban River. Water and sediment were collected from four sampling stations on each river. Water samples were filtered with 0.45 μm membrane filter and acidified to pH<2 and conducted by means of ICP-OES while AAS was used for sediment analysis prior to aqua regia digestion... Mehr ...
