Study on metal concentrations in water of Bukit Merah Lake
was conducted in April 2009. Fifteen sampling stations were chosen and surface water samples for
metals determination were collected. Some water quality parameters such as temperature,
conductivity, dissolved oxygen, pH, and water hardness were determined at each station. Eleven
metals i.e. cadmium, zinc, lead, copper, nickel, ion, cobalt, aluminium, barium, cromium dan
manganese were determined in water samples. Results show that in general metals concentration
were lower than maximum concentrations allowed by Malaysian and international standards in
protecting aquatic life except for Fe and Al. For water quality parameters, study showed that all
parameters are in natural concentration range (class I) according to National Water Quality
Standard (NWQS Malaysia) except for dissolved oxygen and pH at some sampling stations especially
at east side of the lake which were influenced by natural and anthropogenic factors.
