Analysis of heavy metals in fluvial sediments affected by coal spill waters in Lampuuk Beach, Aceh Province, Indonesia

Coal spill in Lampuuk waters in July 2018 had released some heavy metals into the waters in form of dissolved ions. They werethen partially absorbed in the bed and affected the fluvial sediments. The objective of the research was to analyse the heavy metals; Mn, Pb, Cu and Cd content in fluvial sediments affected by coal spill water in Lampuuk, Aceh Province, Indonesia.The fluvial sediments from five stations of Lampuuk beach were collected in December 2018 and analyzed using Atomic Absorption Spectrophotometer (AAS), then resulted that lead (Pb) and manganese (Mn) contained in the samples, ranged from 10.14 to 15.91 and 60.25 to 98.78 mg/Kg, respectively, while copper (Cu) and Cadmium (Cd) were undetected. Based on the regulation of ANZECC (2000), lead content in the sediment was still under the threshold, but manganese was exceeded the threshold.
