ABSTRACT

Observation of heavy metal content in sea water at Aquatic Situbondo was conducted in
March-April 2010. Heavy metals studied are Pb, Cd and Hg. This observation has to do with pollution
in coastal waters Situbondo. This observation was done in peiaran Situbondo (7 stations) and samples
of farmed fish, grouper in floating net cages. Results showed the mean Pb levels in all study sites
ranged between 0.0018-0.0032 ppm. The highest mean Pb levels were found near the coast that is
0.0032 ppm, still in accordance with the Threshold Limit Value (NAV for the benefit of marine life
that is at 0008 ppm. Analysis of lead content in fish flesh and gills 1.3625 ppm 0.2298 ppm. The
average Cd concentration in all study sites is ranged from 0.0012 to 0.0019 ppm or <2 ppb value is
still in the Threshold Limit Value (NAV) for a range of marine interests of the Cd concentration is
0001 ppm or 1 ppb. Groupers are cultured in floating net cage (cage) of results analysis of Cd
content in fish flesh ranged from 0.1113 to 0.2049 ppm and gills ranged from 0.0528 to 0.0956
ppm. The average Hg concentration at all study sites is 0.001 to 0.0015 ppm. Concentration is
relatively low and not harmful to aquatic biota, especially fish. TLV is 0001 ppm Hg for marine
biota. The content of Hg in fish flesh ranged from 0.0043 to 0.0068 ppm and Grouper in the gills of
grouper ranged 0.0019 to 0.0038 ppm. It can be concluded that the heavy metal content (Pb, Cd,
and Hg) in water samples and fish in the waters Situbondo grouper aquaculture is still in accordance
with the threshold value (NAV), which ditatapkan by KNLH, 2004 for the benefit of marine life.
