Heavy metals and polycyclic aromatic hydrocarbons compounds (PAHs) are compounds that can cause environmental pollution. One of the environment that can be polluted is the sea, especially in its sediment. The pollution caused from heavy metals and PAH are dangerous for the survival of human beings and other living creatures. Therefore, the development of methods to determine heavy metals and PAHs in marine sediment is done. The examined heavy metals are Cu, Ni, Pb, Cd and Cr; while PAH that examined are naphtalene, phenantrene and anthracene. The sample used in this research was taken from the Marunda’s beach, North Jakarta. The methods used to analyze heavy metals are external standard method, and standard addition method with atomic absorption spectroscopy (AAS) using the principle of flame.
