“…This reflected the high PAHs input from terrestrial activities. This is also found in the Luan River estuary, Hai River estuary, and Zhangweixin River estuary (Yan et al, 2016), Teluk Jakarta (Ahmad, 2012), Mahakam river (Hadibarata et al, 2019) where the concentration value at rivers and estuaries / bays are affected by differences in organic pollutant input from the activities above them such as commercial, residential and industrial activities. High concentrations in the sea on sediment, which are close to river estuaries such as Mbr, Sdf and TjP as well as at pond locations, namely Mbr and Krp, indicate that the estuary is an area that accumulates PAHs.…”

“…High concentrations in the sea on sediment, which are close to river estuaries such as Mbr, Sdf and TjP as well as at pond locations, namely Mbr and Krp, indicate that the estuary is an area that accumulates PAHs. The concentration of PAHs in water in Tarakan City river is still smaller than that of Dalian river , Luan, Hai, and Zhangweixin rivers (Yan et al, 2016) (Table 7.). In seawater, there were lower levels than in Pearl River estuary (Niu et al, 2018), Liaodong Bay , Coastal area of Dalian , and Coastal Alexandria (Ahmed et al, 2017).…”

“…Anthropogenic activities such as waste or oil spills containing PAHs, industrial waste, urban runoff which are discharged directly into the aquatic environment, emissions from the atmosphere such as petroleum refineries, industrial incinerators, and burning agricultural land also pose a contributing factor (Neff, 1979). The presence and concentration of PAHs in aquatic ecosystems often correlate with industrial discharge, spills, atmospheric deposition, and fuel combustion (Yan et al, 2016). From the literature study, land-based activities constitute PAHs sources in the coastal waters of Tarakan City.…”

PAHs are mutagenic and carcinogenic agents that influence the coastal water of Tarakan City. This study aims to determine the concentration, type, and distribution of PAHs in waters and sediments of rivers, seawater, and brackish ponds, and their potential sources. Fourteen samples of water and sediment from selected stations obtained 14 types of PAHs priority (USEPA). Analysis using GC-MS Type Thermo Trace 1310 single quadrupole Mass Spectrometer, using Coulum melting silica column (coulumn fused silica) DB5 MS with a length of 30 m, a diameter of 0.32 mm inline. The concentration in sediments at river locations ranges from 0.72-352.84, between 1.23-606.74 in the sea, and brackish ponds 0.08-2858.88 ng.g-1. On the waters ranged from 42.46-160.25 µg.L-1, in the sea 7.95-167.55 µg.L-1 and ponds 7.63-151.60 µg.L-1. The concentration level in rivers and seas is small and in the ponds is small-very high. The concentration on water at the river site was observed to increase from upstream to downstream. Meanwhile in sediment was higher in the upstream decreased towards the middle of river and increased in downstream/estuary area. The concentration in the Tarakan coastal environment signifies the potential hazards to the environment. Components Nap, Fla, Pyr, Chr, and BaP are types that are often identified. Furthermore, two, four and five rings of PAHs were shown to dominate in water and sediment, with the major rings present in both river and brackish pond. The PAHs were both petrogenic and pyrolytic sources from land base sources that were possibly derived from the Pamusian river.

“…The sources of PAHs are broadly categorized into three types: pyrogenic-derived from the incomplete combustion; petrogenic-caused by the petroleum sources; and diagenic-derived from plant materials and precursors (Zakaria et al 2002). PAHs comprised of two to six fused aromatic rings in which PAH compounds with two and three rings (low molecular weight) have a significant acute toxicity, whereas some of the PAH compounds with more than three rings (high molecular weight) are carcinogenic (Yan et al 2016, Yin et al 2015. Due to low volatility and low water solubility, PAHs in marine environment tend to accumulate in finegrained sediments and suspended particles, which eventually impact benthic organisms.…”

Formation of oil-suspended sediment aggregates (OSAs) is believed to be one of the natural cleaning processes in the marine environment. In this study, we have investigated the formation processes of OSAs under different mixing periods (continuous mixing and with the addition of sediments in between), oil-sediment ratios (1:1, 1:2 and 2:1) and crude oils (Arabian Light (AL), Kuwait (KW) and Murban (MB)). The results revealed that size of OSAs significantly increased (up to ≈ 1.41 mm) with the addition of sediments. Aggregates (total 36) were extracted for n-alkanes and polycyclic aromatic hydrocarbons to quantify and assess their weathering and toxic levels. The maximum n-alkane depletion was 84% (111-02), 94% (212-02) and 84% (321-02) and PAH depletion was ≈ 72% (111-02), 79% (212-02) and 81% (311-03) for the OSAs of AL, KW and MB crude oils, respectively, for the different samples considered, indicating that n-alkanes were depleted relatively higher than the PAHs. The highest depletion of both n-alkane and PAHs has occurred in OSAs of 10-h continuous mixing. The depletion of both n-alkane and PAHs reduced after the addition of sediments, however, escalated the growth of OSAs, resulting in bigger size OSAs. The concentration of PAHs of all 36 OSAs is greater than 5000 ng/g, indicating very high PAH pollution. Though the formation of OSAs helps in cleaning the spill sites, the carcinogenic threat to the marine ecosystem caused by these OSAs cannot be ignored.

“…Such effects are depend on point and non-point sources of apportionment, bioavailability when pollutant reaches the environment matrices, their environment fate, the ability of the organisms to accumulate and metabolize various hydrocarbons that may lead to alteration of survival and reproduction rate in the environment. The long-term effects of petroleum hydrocarbons in the may result in noticeable ecological changes such as possible impairment of fisheries resources (Yan, Liu, Shi, You, & Cao, 2016) and changes in microbial community structure (Nayar, Goh, & Chou, 2004;Syakti et al, 2006).…”

As maritime fulcrum nation, in Indonesia, marine environmental analytical chemistry field is still under developed. So that why, this review paper aims to provide basic understanding of the use some molecular diagnostic indices using n-alkanes indexes and polycyclic aromatic hydrocarbons (PAHs) diagnostic ratios to estimate the source of apportionment of the hydrocarbons contamination and origin. The n-alkane chromatograms were then used to characterize the predominance of petrogenic or biogenic either terrestrial or aquatic. Furthermore, characterization allowed to discriminate riverine versus marine input. The occurrence of a broad unresolved complex mixture can be an evidence of biodegraded petroleum residues. For aromatic compounds, the prevalence of petrogenic, pyrolitic, and combustion-derived can be easily plotted by using isomers ratio calculation. This paper thus provides useful information on the hydrocarbon contamination origin, especially in marine sediments. Further researches should be undertaken in order to validate the use of molecular diagnostic ratio with isotopic approach.
