The Characteristics of Naphthalene and Phenanthrene as Polycyclic Aromatic Hydrocarbons (PAH) Compounds in the Marine Sediment of Tanjung Bayang Beach in Makassar

Abstract

This research is an exploratory study that aims to determine the levels of naphthalene and phenanthrene PAH compounds and the level of pollution contained in the marine sediments of The Tanjung Bayang Makassar Beach. The steps of this study include sample preparation, extraction using the socletation method with n-hexane: dichloromethane solvent, fractionation using Chromatography Column Flash (CCF) methods and determination of naphthalene and phenanthrene levels using the HPLC instrument. The results of the PAH fraction in the form of yellow powder were identified using HPLC by comparing the retention time of the standard chromatogram of naphthalene and phenanthrene with of the chromatogram sample. In this study, the concentration of naphthalene and phenanthrene PAH compounds was observed in three stations coded as TB1, TB2 and TB3. TB1 Station has the highest PAH level where the naphthalene content reaches 165.5450 ppm and phenanthrene content is 934.3698 ppm with a total content of 1099.9148 ppm. TB2 Station has the lowest PAH with 85.4858 ppm naphthalene level and phenanthrene at 509.0401 ppm with a total of 594.5259 ppm. TB3 station is at 120.8489 ppm naphthalene level and phenanthrene levels of 693.9341 ppm with the total levels of 814.7832 ppm. The marine sediments PAH content in Tanjung Bayang Makassar Beach is at moderate-high pollution levels.
