Muara Sungai Musi dan Pulau Payung adalah kawasan bagian hilir Sungai Musi yang menerima banyak masukan limbah dan bahan pencemar akibat aktifitas di sepanjang aliran sungai. Polisiklik aromatik hidrokarbon (PAH) adalah salah satu komponen pencemar organik yang keberadaannya mengancam kehidupan biota perairan. Penelitian ini bertujuan untuk mengidentifikasi keberadaan senyawa PAH pada sampel air laut dan sedimen yang berasal dari Muara Sungai Musi dan sekitar Pulau Payung. Pengambilan sampel dilakukan pada bulan Juli 2019. Contoh air laut diambil dengan water sampler pada 5 stasiun penelitian dan contoh sedimen diambil menggunakan ekman grab pada 8 stasiun penelitian. Kadar PAH dianalisa dengan High Performance Liquid Chromatography (HPLC), cara kerja merujuk pada APHA (2017) 6440 B divalidasi. Hasil penelitian menunjukkan bahwa kandungan PAH total dalam sampel air Muara Sungai Musi dan sekitar Pulau Payung berkisar antara batas minimum deteksi alat (<0,004)-0,0,62 ppb. Adapun kandungan PAH total dalam sampel sedimen berkisar antara 11,92-558,41 ppb. Secara keseluruhan terlihat bahwa kandungan PAH dalam sampel air dan sedimen yang berasal dari Sungai Musi dan sekitar Pulau Payung masih aman bagi organisme. Musi River Estuary and Payung Island are the downstream areas of the Musi River which receive a lot of inputs of waste and pollutants due to activities along the river flow. Polycyclic aromatic hydrocarbons (PAHs) is one component of organic pollutants which dangerous for the aquatic organism. This study aims to identify the PAHs compounds in seawater and sediment samples from the Musi River Estuary and around Payung Island. Sampling was carried out in July 2019. Seawater samples were taken with a water sampler and sediment samples were taken using ekman grab at 7 research stations. PAH levels were analyzed by High Performance Liquid Chromatography (HPLC), the method refers to APHA (2017) 6440 B. The results showed that the PAH content in the Muara River Musi water samples and around Payung Island ranged from under detection limit(<0,004)-0.62 ppb. The PAH content in sediment samples ranged from 11.92-558.41 ppb. Overall PAHs content in water and sediment samples from the Musi River and around Payung Island are still good for the aquatic organism.

Abstract Background Polycyclic aromatic hydrocarbons (PAHs) have attracted worldwide attention due to their carcinogenic, teratogenic and mutagenic effects, environmental persistence and bioaccumulation characteristics. Therefore, the sensitive, reliable and rapid detection of PAHs in sediment is of great importance. Objective To develop a high-performance liquid chromatography (HPLC) with fluorescence and ultraviolet detection after QuEChERS treatment for simultaneous determination of 16 U.S. Environmental Protection Agency priority PAHs in sediment samples. Methods The samples were ultrasonically extracted with acetone and then the supernatant was purified with a modified QuEChERS method. After centrifugation, the supernatant was injected into the HPLC system for analysis. The separation was accomplished on a ZORBAX Eclipse PAH column (150 × 4.6 mm, 3.5 μm) and the column temperature was set at 30 °C. The flow rate of the mobile phase consisting of water and acetonitrile in gradient elution mode was fixed at 0.9 mL/min. Detection was conducted on an ultraviolet detector and a fluorescence detector simultaneously. The qualitative analysis was based on retention time and the quantification was based on standard curves. Results Under the optimal conditions, this method showed good linearities in the range of 10–200 μg/L with correlation coefficients greater than 0.9993. The method had the limits of detection (LODs) ranging from 0.00108 to 0.314 ng/g. The mean recoveries ranged from 78.4 to 117% with the intra-day and inter-day relative standard deviations (RSDs) of 0.592–10.7 and 1.01–13.0%, respectively. The proposed method was successfully applied to the detection of 16 PAHs in sediment samples collected from the Funan River in Chengdu, China with the total contents of 431 to 2143 ng/g·dw. Conclusions The established method is simple, rapid, environment-friendly and cost- effective. It can be applied to the analysis of 16 PAHs in sediment samples. Highlights A method of QuEChERS with ultrasound-assisted extraction combined with HPLC has been established for the analysis of 16 PAHs in sediment samples and the proposed method has been successfully applied to the analysis PAHs in real sediment samples.

A sensitive and fast method was developed to quantitatively analyse the six polycyclic aromatic hydrocarbons (fluoranthene (FLT), benzo[b]fluoranthene (BbF), benzo[k]fluoranthene (BkF), benzo[a]pyrene (Bap), benzo[ghi]perylene (BghiP) and indeno[1,2,3-cd]pyrene (INPY)) by high performance liquid chromatography (UPLC) coupling with tandem mass spectrometry (MS/MS). Chromatographic separation was performed on a Waters Acquity UPLCTM BEHC18 column (1.7 μm, 2.1 mm × 50 mm). A 0.2 μm precolumn filter was used to protect the analytical column. Mobile phase A was acetonitrile containing 0.5% toluene. Mobile phase B was water. Linearity of detection was in the range of 1–100 μg L−1; LOD of 5 PAHs were lower than 0.1 μg L−1; LOQ were 0.2 μg L−1 except for benzo[k]fluoranthene. The LOD and the LOQ of benzo[k]fluoranthene were respectively 0.1 μg L−1 and 0.8 μg L−1. Wastewater samples collected from two wastewater treatment plants were determined using this method respectively. Recovery of all compounds varied from 67.8 ± 10.6% to 113.2 ± 7.2%. In comparison with the existing methods, this rapid method saves time and solvent and improves instrument sample throughput by 2–5 fold.
