Abstract
The water of Belawan Sea have a wealth of marine resources that are quite important to supporting the economy surrounding communities. This study aims to measure the content of heavy metals lead, Pb (sediment and white shrimp) and how much heavy metal of lead is accumulated by white shrimp (Penaeus merguiensis) from sediments. Lead, Pb of heavy metals in white shrimp and sediments were analyzed by using Atomic Absorption Spectrophotometer (AAS). The results showed that the average concentration of Pb heavy metals in sediments was found of 5,90-6,78 mg / kg, when the average concentration range of Pb heavy metals in white shrimp was found of 0,014-0,089 mg / kg, while the average accumulation of heavy metals Pb in white shrimp from sediments was found the value of 0,0075. The bioaccumulation value categorized was lower because the value was found below than 1. Penaeus merguiensis indicator of organisms can be used in measuring exposure to heavy metal Pb in water.
