Kandungan Logam Berat Pb pada Air, Sedimen, dan Kerang Darah (Anadara granosa) di Pantai Belawan, Provinsi Sumatera Utara

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.
