dc.description.abstract | Metals and other minerals commonly found in fresh water and sea water,
although the amount is very limited. Heavy metals into the waters will pollute the
sea. One suspected of marine life will be affected due to degradation of water and
sediment in coastal environments is shellfish. This study aims to quantify the
amount of lead concentrations of heavy metals in water, sediment, body shells
(Anadara Granosa) and heavy metals analyzed the correlation between water,
sediment and shellfish .
This study conducted in June-August in 2013 in the waters of Belawan
Beach, Village Deli Chart, District of Medan Belawan, North Sumatra Province.
point stations observed were three stations. Parameters measured were water
physicochemical parameters and heavy metal concentrations of lead in the water
column, sediment, and shellfish are then analyzed using atomic absorption
spectrophotometer (AAS).
The results of research on water showed heavy metal concentrations of lead
ranged between 0.64 to 0.91 mg / L. while lead concentrations in sediments ranged
from 60.78 to 71.56 and lead concentrations in mussels ranged from 10.48 to 12.03
mg / kg. These results indicate that water, sediment, and shellfish contaminated
with heavy metals lead already on the beach Belawan. | en_US |
