Banten Bay is end of stream for a few rivers from Banten mainland where many manufactures and petrochemical industries are built. This may give environmental pressure of water quality of the bay due to pollutant input, such as Polycyclic Aromatic Hydrocarbons (PAHs). This study is to identify those pollutants and determine their total concentration and distribution in sediments. Surface sediment samples were collected in four zones: inner coastline within the bay, middle bay, coastline off the bay and outer of the Bay in April 2016. PAH components were extracted and measured using a gas chromatography-mass spectrometry. Levels of total PAHs in sediments in inner coastline within the bay ranged between 0.381-2.654 ppm with an average of 1.288 ppm, middle of the bay ranged between 0.747-1.762 ppm with an average of 1.198 ppm, outer of the bay ranged between 0.192-1.394 ppm with an average of 0.921 ppm, and east coast of the bay ranged between 0.191-1.394 ppm and an average of 0.778 ppm. The levels of total PAH contamination is apparently lower than those of PAH threshold in sediments (i.e. 4.5 ppm).Keywords: PAHs (Polycyclic Aromatic Hydrocarbons), Banten Bay Teluk Banten merupakan muara dari beberapa sungai di daratan utama Banten yang sebagian besar berupa kawasan industri dan kegiatan lain sekitar laut. Kondisi ini berpotensi memberikan tekanan terhadap kualitas perairan Teluk Banten karena masukan bahan pencemar diantaranya senyawa Polisiklik Aromatik Hidrokarbon (PAH). Penelitian ini bertujuan mengidentifikasi PAH dan menentukan konsentrasi total dan distribusinya di sedimen. Pengambilan sampel sedimen permukaan pada April 2016 diempat zona: zona pantai bagian dalam teluk, bagian tengah teluk, pantai bagian luar teluk, dan bagian luar teluk. Konsentrasi PAH diukur menggunakan alat kromatografi gas spektrometer massa (GCMS). Konsentrasi total PAH dalam sedimen pantai bagian dalam berkisar antara 0,381-2,654 ppm dengan rata-rata sebesar 1,288 ppm. Bagian tengah teluk berkisar antara 0,747-1,762 ppm dengan rata-rata sebesar 1,198 ppm, bagian luar teluk antara 0,192-1,394 ppm dengan rata-rata sebesar 0,921 ppm dan pantai bagian timur teluk antara 0,191-1,394 ppm dengan rata-rata sebesar 0,778 ppm. Level pencemaran total PAH di perairan Teluk Banten dalam sedimen mengindikasikan masih lebih rendah dari standar bakumutu PAH dalam sedimen yaitu 4,5 ppm.Kata kunci: PAH (Polisiklik Aromatik Hidrokarbon), Teluk Banten

Background. Polycyclic aromatic hydrocarbons (PAHs) are toxic contaminants and pose health risks to humans and the ecosystem due to their persistence in the environment. Objectives. This study determined the concentrations of PAHs in sediment, two species of fish (Drepane africana and Pomadasys jubelini), crabs (Callinectes amnicola) and shrimps (Penaeus notialis) around the Atlas Cove jetty, Lagos, Nigeria. Methods. Polycyclic aromatic hydrocarbons were extracted from fish, shrimp, and crabs that were purchased from local fishermen. Sediments were collected at five locations impacted by ship movement and cargo offloading around the Atlas Cove jetty during the period of June to August 2016, using standard methods. Potential toxicity of PAHs in the sediments on the surrounding aquatic organisms was assessed. The PAHs were analyzed using gas chromatography-mass spectrometry. Human health risk assessment was calculated from biota using dietary daily intake and carcinogenic potencies of individual PAH concentrations. Results. A total of 17 PAH congeners were detected in sediment samples and ten were detected in biota samples. Concentrations of total PAHs obtained in sediment and fish samples ranged from 2.15 - 36.46 mg/kg and 11.89 - 71.06 mg/kg, respectively. The total PAHs concentration pattern follow the order of P. notialis > C. amnicola > P. jubelini (whole) > D. africana (whole) > D. africana (fillet) > P. jubelini (fillet) > sediment. Concentrations of total PAHs were higher in whole fish than in fillet samples (muscle) in both fish species. High values of PAHs were recorded in the dietary intake (0.10 - 2.33 mg/kg body weight/day) of the organisms. Toxic equivalent quotient values (0.01 to 0.10 mg/kg) were observed to be higher than the screening values (0.0014 to 0.0599 mg/kg). In the muscle of Drepane africana and Pomadasys jubelini, splitting and atrophy of the muscle bundles were observed. Conclusions. The concentrations of PAHs in analyzed sediment and organisms were higher than the maximum permissible limit of the United State Environmental Protection Agency (USEPA). Most of the detected PAHs were of petrogenic origin, which is an indication that anthropogenic activities were influencing PAH concentrations. Competing Interests.

AbstractThere are numerous sources of chemical pollutants which can impact the mangrove ecosystem through adjacent waters, industrial and sewage discharges and air depositions. Polycyclic aromatic hydrocarbons (PAHs) are semi volatile ubiquitous anthropogenic pollutants detected in all environmental compartments. In the monitoring framework for the mangrove ecosystem along the Red Sea coast of Saudi Arabia, nine mangrove stands were examined for the accumulation of PAHs. Polycyclic aromatic hydrocarbons were measured using Gas Chromatography-Mass Spectrometry (GC-MS). The mean values detected for total PAHs in sediments, roots and leaf were 2.98, 8.57 and 23.43 ng/g respectively. The trend of the total PAHs concentration in all sites showed the descending order: leaf > roots > sediments. Beside the sandy nature of the sediments, the presences of all stands in remote areas fare from the direct anthropogenic effects lead to these relative low values. PAH bio-concentration factors for leaf are two to three magnitudes higher than that in roots, suggesting atmosphere deposition /leaf uptake mechanism in addition to the sediment/root mechanism. The diagnostic ratios revealed that the sources of PAHs are mainly pyrogenic.

Degradation of polycyclic aromatic hydrocarbons (PAHs) and microbial quantity were investigated in aged PAHs-contaminated soil in a pot experiment with regrass and alfalfa. After 60 days germination the concentration of total PAHs in soil decreased by 37.57% and 38.41% with the treatment of ryegrass-microbe agent and alfalfa-microbe agent. The processes of ryegrass and alfalfa were 18.72% and 19.34%. The root system promoted the quantity of microbe and the microbial agent was benefit for the PAHs degrading microbe. And there was significant positive correlation between the number of PAHs degrading microorganisms and the removal rate of PAHs in the soil.

Objective: As part of our program to investigate the possible role of environmental pollutants in the incidence of breast cancer in India, we conducted for the first time a hospital based case-control study where blood polycyclic aromatic hydrocarbons (PAHs) levels were determined in women suffering from benign and malignant breast lesions, and compared with those of disease free controls drawn from similar socioeconomic environment residing in and around New Delhi, India. Material & Methods: Anthracene, phenanthrene, fluoranthene, naphthalene, pyrene, benzo (a) pyrene, benzo (k) fluoranthene and dibenzo (a,h) anthracene were determined by HPLC-FD. Results: Level of total PAHs in control, benign and malignant groups (30 numbers in each) were 142.05 ± 50.84, 185.99 ± 61.97 and 200.74 ± 55.05 μg / L respectively. Mean levels of naphthalene, phenanthrene, pyrene and benzo (k) fluoranthene were higher in both malignant and benign groups than in control but the difference was not statistically significant. Of the total PAHs, 3–ringed compounds were found much higher (89%) in controls than in benign (52%) and malignant groups (54%). However, the percentage sum of 2, 4 and 5-ringed PAHs were much higher in malignant (46%) and benign (48%) groups when compared with those of controls (11%). Conclusion: Results of the present study indicate that higher levels of PAHs (especially non-carcinogenic), though statistically non-significant, were present in cases with benign and malignant breast lesions than in those of controls.
