Abstract |
This research was conducted to assess the water quality and the
contamination of heavy metals in water, sediment, fish, and frogs, as
well as bioaccumulation factors (BAFs) in fish and frogs around the
gold mine area. The water samples were analyzed for water quality
(temperature, pH, and dissolved oxygen). The samples were analyzed
for heavy metals by inductively coupled plasma optical emission
spectrometry. The water quality was within the standard. The
concentrations of heavy metals, including As, Cr, Cd, Pb, Ni, Zn, Fe, Mn,
and Cu, in water and sediment samples were measured. Three species
of fish were collected: Rasbora tornieri, Brachydanio albolineata, and
Systomus rubripinnis. The mean heavy metal concentrations of fish
were as follows: Fe>Zn>Mn>Cr>Ni>Cu>As>Pb>Cd. The As, Cr, and
Pb concentrations in all the fish species exceeded the standard levels.
Five species of frogs were collected: Kaloula pulchra, Microhyla
heymonsi, Fejervarya limnocharis, Hoplobatrachus rugulosus, and
Microhyla pulchra. The mean heavy metal concentrations of frog were
as follows: Fe>Cu>Mn>Zn>Cr>Ni>Pb>Cd>As. The Cr, Cd, and Cu
concentrations exceeded the standard levels. The BAFs in fish were
in order of Cr>Zn>Ni>Cu>Pb>Fe>Cd>As. The BAFs in frogs were
Cr>Zn>Ni>Cu>Fe>Pb>Cd>As. The accumulation of heavy metals
was higher in the sediment than in the water. Many aquatic organisms
take up heavy metals directly from the environment around the gold
mine. |
