Kandungan senyawa polisiklik aromatik hidrokarbon dalam air laut dan sedimen di Teluk Lampung

Abstract

Polycyclic Aromatic Hydrocarbons (PAH) are polycyclic aromatic organic compounds that are toxic to humans and aquatic organisms. This research aims to determine the level of pollution of PAH compounds in seawater and sediments in Lampung Bay, Lampung. This research was conducted by survey method in November 2018. Sediments and seawater samples were taken using water and sediment sampling equipment. Sediment and seawater samples were taken at three and two research stations. The levels and types of PAH compounds were determined by using Gas Mass Spectrometry Chromatography and their sources using individual ratio diagnostic methods. The results showed that the levels of PAH total in seawater ranged 295,587-331,133 ppb, this level is relatively high and has passed the threshold values set by the Decision Letter of the Office of the State Minister of Environment No 51, 2004 for marine biota protection, while in the sediments range 51.481-62.448 ppb, this level is relatively small and still in accordance with the criteria for marine life. The results of individual ratios diagnosis analysis indicate that PAHs in seawater and sediment come from various sources, namely petroleum, burning of petroleum and burning of organic matter.
