| description | The mining and processing of gold traditionally give effect to the
environment pollution. Mercury waste of processing gold is thrown open place up
to the river and accumulated at the estuaries. The characteristic of the high
toxicity of mercury can result in imbalance waters ecosystems. This research aims
to know the mercury content of mudskipper, water, and sediment in the estuaries
Sekotong West Lombok.
Fish sampling was done directly with nets used techniques Seine net,
while getting water samples used gallons and sediment samples used Dredge at
estuaries of Selodong, Blongas, Pelangan, Tembowong Gawah, Pundak, and
Sekotong. Measuring environmental parameters was done in five estuaries
covering sediments and water temperature, salinity, pH of sediment and the water,
DO, COD, and BOD. Samples of fish which were fixed, water and sediment were
tested by mercury content in laboratory of LPPT UGM. Mercury content of the
data obtained was analyzed comparatively by mercury standard according to
Environment ministry decision No. 51/2004, decision of Ditjend POM
No.03725/B/SK/VII 1998 and Indonesian government�s regulation No. 18 Year
1999.
The results indicate the presence of mercury pollution that exceed the
threshold quality standard. Spatially highest content of mercury in the water was
Blongas estuary with an average of 0.003627 ppm and the lowest at the TGP
estuary with an average of 0.00026 ppm. The highest content of mercury in
sediments was Pelangan estuary with an average 1.797 ppm and the lowest was
Selodong estuary with an average of 0.567835 ppm. The highest content of
mercury in fish was Blongas estuary 2.781128 ppm and the lowest was Sekotong
estuary with an average 0.366298 ppm. Temporally with the highest mercury
content of water in 2009 was Blongas estuary of 0.00694 ppm, and in 2011 was
Sekotong estuary of 0.00181 ppm. The highest mercury content of the sediment in
2009 was Pelangan estuary at 3.48 ppm and in 2011 was Sekotong estuary of
2.05767 ppm. The average of mercury highest content in fish in 2009 was
4.380425 ppm and in 2011 was 2.0105 ppm. |
