KANDUNGAN LOGAM BERAT TEMBAGA (Cu) PADA SIPUT MERAH (Cerithidea sp) DI PERAIRAN LAUT DUMAI PROVINSI RIAU
Abstract: Conducted a study to
determine the concentration of heavy metals copper ( Cu ) on the Red Snail (Cerithidea
sp) on Sea waters Dumai conducted in May and June 2011. The method used was a
survey method , in which the station is purposive determination of systematic
sampling at three observation stations . The main parameters measured were cu
metal content in sea water , sediments and Cerithidea sp and the level of
accumulation of heavy metals Cu . While supporters of the parameters are
temperature , brightness , salinity , pH , dissolved oxygen , organic matter
content and the type of substrate . Heavy metal concentrations of Cu were
analyzed using AAS ( Atomic Absorption Spectrophotometer ). The data were
analyzed descriptions. The results showed Cu concentrations of heavy metals in
sea water range from 0.102 ppm - 0.175 ppm. Cu content of heavy metals in
sediments ranged from 1.323 ppm - 3.631 ppm. While the concentration of Cu on
Cerithidea sp ranged from 1.264 ppm - 2.592 ppm. Cu concentration of heavy
metals in marine waters Dumai has passed the threshold for sea water quality,
while the heavy metal concentrations of Cu in Cerithidea sp has not passed the
threshold. Biological value of Cu concentration factor on Cerithidea sp ranged
from 12.3 to 19.3. This shows the level of accumulation of heavy metals Cu is
low.
