| Summary: | The concentrations of toxic metals were determined in estuary and freshwater zones from
Kuantan River basin. Water samples were collected from the surface and bottom layers of nine
sampling stations, from the downstream of the estuary towards the upstream along the mainstream
drainage channel, traversing past the city center and industries of Kuantan city. The general
physico-chemical parameters (salinity, temperature, pH and dissolved oxygen) and concentration
of total dissolved metals, Cadmium (Cd), Chromium (Cr) and Lead (Pb)were measured during dry
season (May and June 2012) and wet season (September and October 2012). Metal concentration
was determined using Inductively Coupled Plasma Mass Spectrometry (ICP-MS).Metal
concentrations ranged from 0.299 - 1.815µg/Lfor Cr, undetectable to 0.034µg/L for Cd and 4.697
– 16.017µg/L for Pb, respectively. The present measurements can be used as a baseline data for
any future monitoring and comparison of trace metals distribution in the Kuantan River. |
