1 Introduction
The polycyclic aromatic hydrocarbons (PAHs) are pollutants of concern due to their persistence in the marine ecosystem, thus it can cause long term adverse effect to the marine life (
Elias et al., 2007). These organic contaminants are resistant to degradation, can remain in the environment for long periods, and have the potential to cause adverse environmental effects. Some of them are susceptible to dispersion on a global scale because they are semivolatile, move between the atmosphere and the Earth's surface in repeated, temperature-driven cycles of deposition and volatilisation (
Wania and Mackay, 1996). Persistent organic pollutants (POPs) like PAHs, are truly multimedia contaminants which occur in all parts of the environment: atmosphere, inland and sea waters, remote/far away from industrial activities (
Neff, 1979). In general, PAHs are occurred in all parts of the environment: atmosphere, water, sediments, soils and vegetation (
Wild and Jones, 1995;
Wania and Mackay, 1996) not only from places close to industrial areas, but also in remote/far away from industrial activities. PAHs are formed through natural and anthropogenic processes (
Boehm, 2006), for example biosynthesis, diagenesis of organic materials that produce fossil fuel, and incomplete combustion of organic materials (
Neff, 1979). According to
Nikolaou et al (2009), there are three sources of PAHs: (1) Petrogenic PAHs, including petroleum, with its products such as crude oils, (2) Biogenic PAHs, from biological process or early step of diagenesis on marine sediment (i.e. perylene), (3) Pyrogenic PAHs, from fuel combustion (petroleum and coal) and wood.
PAHs diagenesis is produced naturally when the organic material deposited on the sediment. PAHs which is produced relatively faster (day up to year) at low temperature (< 70℃) occur on condition with depletion of oxygen and microorganisms involvement such as bacteria. This process is recognized as aromatization reaction and produce aromatic biomarker that was found in the new sediment. The initial diagenesis product is perylene with 5 rings PAHs. Perylene usually found in the river sediment, pond and the sea, where there is an oxygen depletion (
Boehm, 2006). Organic material diagenesis from the diatom and plant material are source of perylene in anoxic sediment of the sea (
Venkatesan, 1998;
Boehm, 2006).
Tolosa et al (2009) reported that in the Cienfuegos Bay, Cuba, perylene (PAHs natural) was found over in the estuarine areas of Damuji and Salado rivers. PAHs produced in the early diagenesis with a simple biology precursor only include some of PAHs, so that, it differentiated between multispecies complex of PAHs petrogenic and pyrogenic (
Boehm, 2006). The objective of the research was to study preliminary analyses concentration of Polycyclic Aromatic Hydrocarbon (PAHs) in the sediments and milkfish (
Chanos chanos, Forskal) at Marunda and Blanakan ponds, Indonesia. The results of study will give information regarding with the PAHs contribution in human activity in the environment.

3 Discussions
3.1 PAHs in Marunda and Blanakan sediments
In Marunda and Blanakan ponds, the components of PAHs consisted of non-branched or non-alkylated PAHs. PAHs that were detected composed of 2, 3 and 4 benzena ring. It showed that sediment at Marunda ponds were already contaminated with petroleum and pyrogenic PAHs resulting from fuel combustion (
Zhang et al., 2004;
Boehm, 2006;
Bouloubassi et al., 2006). The PAHs compounds detected in Marunda and Blanakan ponds were compounds that considered as primary pollutant according to US EPA (
Boehm, 2006).
The contamination of petroleum at Marunda ponds (located closed to Jakarta Bay), occured because Jakarta Bay is used as cross-nation transportation for fishermen boats, ships and tanker from many offshore rig’s companies under Pertamina Authority of Kepulauan Seribu (
Salim, 2000). Oil contamination can reach to the coastal/land areas through the tides action of seawater. In addition, it was also caused by human activities such as the use of leaded gasoline for their vehicles and oil/lubricant that are discharged to the sea. Moreover, industrial activities also contribute for the contamination. Range of total PAHs concentrations in Marunda sediment were lower compared to the result obtained by
Zhang et al (2004) at surface sediment on mangrove areas of Deep Bay, China. The range of PAHs found were 238 ng/g up to 726 ng/g dry weight. On the other hand,
Gogou et al (2000) found that concentration of PAHs total at sediments of Cretan Sea were 14.7 ng/g up to 161.5 ng/g. This showed that concentration of total PAHs in Marunda ponds were between concentration found in China and Cretan Sea.
PAHs compounds that were detected in Blanakan ponds probably derived from agricultural activities that discharge their wastes to Cilamaya River closed to Blanakan ponds. Other source is coming from fishermen boat using leaded gasoline. Value range of total PAHs concentrations in Blanakan sediment obtained at concentrations lower than obtained by
Hu et al (2010) that ranged from 140.6~300.7 ng/g on sediments of Bohai Bay, North China.
Based on statistical analysis, it seemed that in both locations Marunda and Blanakan ponds there were no differences on PAHs concentration. Even though, Blanakan ponds were far away from industrial area, but there are housings and agricultural activities (paddy fields, horticulture and aquaculture). According to
Neff (1979), persistent organic pollutants (POPs) like PAHs, are truly multimedia contaminants which occur in all parts of the environment: atmosphere, inland and sea waters, sediments, soils and vegetation (
Wild and Jones, 1995;
Wania and Mackay, 1996) not only from places closed to industrial areas, but also ones in remote/far away from industrial activities.
3.2 PAHs in the meat and gills Chanos chanos in Marunda and Blanakan
Components with the highest concentrations of total PAHs in the meat and gills of Milkfish in Marunda is Naphthalene. Naphthalene characterized by abenzene ring number 2. This suggests that the meat and gills of Milkfish in Marunda mainly contaminated by petroleum (
Zhang et al., 2004;
Boehm, 2006;
Bouloubassi et al., 2006). Milkfish meat have also been detected by the component PAHs with number of benzene rings 3 and 4, which are derived from petrogenik and pyrogenik. This indicates the influence of high human activity around the location of the research, such as residential, agricultural, industrial and ship activity in the sea.
Concentrations of total PAHs in fish obtained in Marunda generally still low when compared to other research. Other studies have shown that it contains total PAHs in various biota as found by
Tolosa et al (2005) in the gulf of Oman and the fish
Ephinephelus coioides (the orange-spotter grouper) with a concentration range of 11.8~115 ng/g and
Lethrinus nebulosus (Spangled Emperor) with a concentration range of 5.60~43.4 ng/g.
Manan et al (2011) also found concentrations of total PAHs in aquaculture fish (red fish,
Lutjanus erythropterus; grouper,
Epinephelus areolatus and
Mycteroperca tigris, promfret,
Pampus argentius) at Straits of Malacca, Malaysia ranged 130.26~9610.31 ng/g.
4 Data and Methods
4.1 Sampling time and location
Sediment samples collection was carried out using Ekman Grab in January-March 2012, at Marunda Ponds, North Jakarta and Blanakan, Subang, West Java (Figure 3). Only 5~10 cm of sediment surface taken for PAH analysis. Fish samples were collected from each pond using fish net. Sediments and fishes collected from the field location were wrapped with aluminium foil and kept at –20℃ until further analysis. Sampling locations were determined using Global Positioning System (GPS).

4.2 Extraction and fractionation
Samples of sediment and fish were freeze dried to eliminate water content. Approximately 10 g dry weight of sediment was weighted in a glass beaker. Sample was added into the soxhlet apparatus and surrogated with Naphtalene-D8 for recovery assessment. The samples were extracted using 250 mL (50:50 v/v) mixture of dichloromethane (DCM) and hexane. After 18 hours extraction, the extracted samples were evaporated under vacuum until 1 mL using rotary evaporator. About 1 mL of extracted sample was fractioned into subfraction using silica-alumina column with 10 g of silica gel, 10 g of alumina, and about 1 cm height of sodium sulphate anhydrous. Hexane (50 mL) was eluted, pass through into the silica-alumina column to elute aliphatic (C
12–C
34) fraction followed by the 40 ml mixture of DCM and hexane (50:50 v/v) to elute the PAHs fraction. Internal standards of Acenaphthene D8 and Penanthrene D8 were added, the samples were injected to GC-MS (
Prartono and Wolff, 1998;
Elias et al., 2007).
4.3 Gas chromatography-mass spectroscopy (GC-MS) analysis
The PAHs fractions were analysed using GC-MS model Shimadzu QP5000 with selective ion monitoring mode. PAHs fraction were injected into the GC-MS by using DB-5 silica capillary column (30m × 0.25 mm i.d.; 0.25 μm filmed thickness). The column oven temperature was heated to 50℃ for 1 minute, maintained at 25℃/minute up to 195℃ held for 1.5 minutes, rise up 8℃/minutes up to 265℃, rise up 20℃/minutes up to 315℃ held for 5 minutes. Helium gas was used as a carrier gas with flow rate at 1.2 mL/min. The PAHs identification and quantification was based on ion fragmentation and retention time compared to of that the internal PAHs standard.
