Polycyclic Aromatic Hydrocarbons (PAHs) are polycyclic
aromatic organic compounds that are toxic to humans and aquatic organisms. This
research aims to determine the pollution level of PAH compounds in seawater and
sediment at the estuary of Cimandiri River, Pelabuhan Ratu. This research was
conducted in April 2017. Seawater and sediment samples were taken using a water
sampler and sediment grab sampler at 15 research stations. The concentration
and types of PAHs compounds were determined by using a Gas Chromatography-Mass
Spectrometer, and PAH origin with individual ratios diagnostic. The results
showed the total PAH concentration in seawater ranged from 0.0001-0.0117 ppb
and in sediment ranged from 0.001-0.003 ppm. These values are still in line
with the criteria of the seawater and sediment quality guidelines. The PAH
types were dominated by the low molecular weight PAHs, particularly
naphthalene. The results of the diagnostic analysis of individual PAH ratios
indicated that PAHs in seawater were derived from various sources such as
petroleum, petroleum, and organic matter combustion, meanwhile, the source of
PAHs in sediment cannot be identified because many PAH compounds with high
molecular weight are not detected.
Because many PAH high molecule weight compounds are not detected.
