In this study, the distribution and source identification of sedimentary PAHs from 13 rivers running through Jakarta City were investigated. Freeze-dried sediment samples were extracted by pressurized fluid extraction and purified by two-step of column chromatography. PAHs were identified and quantified by gas chromatography-mass spectrometry (GC-MS). High concentrations of PAHs, ranging from 1992 to 17635 ng/g-dw, were observed at all sampling locations. Ratios of alkylated PAHs to parent PAHs exhibited both petrogenic and pyrogenic signatures with predominantly petrogenic inputs. High hopanne concentrations (4238-40375 ng/g dry sediment) supported the petrogenic input to Jakarta’s rivers. The high concentration of PAHs is indicator for organic micropollutant in the aquatic urban environment in Jakarta that may have the potential to cause adverse effect to the environment.

This study investigated the occurrence of polycyclic aromatic hydrocarbons (PAHs) in water and sediment samples collected along the harbour line, Mumbai, India. The ∑PAHs quantified in water and sediment samples were ranged from 8.66 ng/L to 46.74 ng/L and from 2608 ng/g to 134134 ng/g dry wt., respectively. Significantly high concentration of ∑PAHs was found in water samples of Sewri and sediment samples of Mahul (P<0.05). PAH concentrations detected in the present study were several folds higher than the existing sediment quality criteria suggested by various statutory agencies. The PAH composition patterns in water and sediments suggest the dominance of high molecular weight compounds and indicate important pyrolytic and petrogenic sources. The occurrence of PAHs in the marine environment has attracted the attention of the scientific community as these compounds are frequently detected in seawater and sediments at increasing levels and can have adverse health effects on marine organisms and humans. PAH concentrations detected at Sewri-Mahul site were sufficiently high to pose a risk to marine organisms if they are exposed continuously to this concentration. Hence, continuous monitoring of the ecosystem is highly warranted.

<p>The concentrations of 23 polycyclic aromatic hydrocarbons (PAHs; 16 parent and 7 alkylated PAHs) in 113 surface marine sediment samples, 13 on-land sediment samples and 8 subsampled push cores retrieved from the Canadian Arctic Archipelago (CAA) were calculated. PAHs were extracted via accelerated solvent extraction (ASE) and quantified via gas chromatography-mass spectrometry (GC-MS). The sums of the concentrations 16 PAHs in the surface sediments ranged from 7.8 to 247.7 ng g<sup>-1</sup> (dry weight [dw]) basis). The PAH inputs to the sediments have remained constant during the last century and agree with the results obtained for the surface sediments. Diagnostic ratios indicated that the PAHs in the CAA mainly originate from natural petrogenic sources, with some pyrogenic sources. Temporal trends did not indicate major source shifts and largely indicated petrogenic inputs. Overall, the sediments retrieved from the CAA have low PAH concentrations that are mainly natural.</p>

This report presents the development an highly sensitive, stable and reliable OCs analyzing method with GC/MS (gas chromatography/mass spectrometry) and results of OCs (organochlorines) levels in sediments of Thivai River basin. The method recovery ranges from 72% to 129% and meets the requirement for OCs analyzing. 18 composite sediment samples were taken from 18 sites along Thivai river basin from upstream (Formosa Plant sewer mouth –  Lo Ren canal) to downstream (confluence of Thi Vai and Go Gia rivers). The analytical results show that OCs concentration in Thi Vai river sediment (max 1.73 ng/g dry weight) is not higher than those of the reference sites and other river basins in Vietnam and in the world.

Abstract Three methods for the extraction of polycyclic aromatic hydrocarbons (PAHs) from zebra mussels (Dreissena polymorpha) sampled from Hamilton Harbour were compared. Replicate freeze-dried mussel tissue samples were extracted using acid digestion, tissue homogenization (mechanical extraction) and ultra-sonication. Each extract was submitted to a cleanup procedure (alumina chro-matography and Sephadex LH20 gel chromatography), followed by analysis using gas chromatography-mass spectrometry (GC-MS). The three extraction methods were equally efficient, based on a statistical comparison of mean concentrations of individual PAHs. Mussel extracts, when subjected to bioassays with Salmonella typhimurium strain YG1029 (TA100-like) in the presence of an exogenous metabolic activation system (S9), exhibited significant mutagenic responses; these responses varied with the PAH content of the mussel extracts. Sources of PAHs in mussel extracts were determined by examining the profiles of sulfur-containing polycyclic aromatic compounds (thia-arenes). Comparison of the ratios of certain thia-arenes with ratios in source samples enabled identification of vehicular emissions and coal tar-contaminated sediment as two sources of PAH contamination in Hamilton Harbour.

The environmental quality along Aden coasts is affected by the anthropogenic pressure of Aden city. Field work has been carried out to investigate the occurrence of petroleum pollution along these coasts. To determine the status of aliphatic hydrocarbon (AH) (n-C10 to n-C34) and polycyclic aromatic hydrocarbon (PAH) pollution in surface sediments, twenty seven surface sediment samples were collected in July and December 2014 and March 2015 and analysed for AHs and PAHs by using gas chromatography–mass spectrometry (GC-MS) to determine their levels and sources. Concentrations of AHs ranged from 6.25 µg/g at station 5 (Goldmoor) to 41.05 µg/g at station 7 (Al Ghadir coast) with an average of 16.49 µg/g. Concentrations of PAHs were in the range between 0.37 µg/g at station 5 (Goldmoor) and 16.30 µg/g at station 9 (Oil Harbor) with an average of 7.38 µg/g. The study showed that the levels of petroleum hydrocarbons (PHs) in coastal sediments are low and within the allowed limits. The major sources of the pollution were petrogenic in origin, based on the indices of AHs and PAHs. This pollution is a result of localized oil operations and/or heavy ship traffic in the Gulf of Aden. The results will be used to assess the ecosystem quality. Environmental control is recommended to reduce the marine pollution of Aden coasts.

Tempe is a fermented soybean food that is globally renowned for its high protein content. Methods of preparing tempe vary worldwide, and include soaking in vinegar before fermentation. This study aimed to determine the effects of soaking in vinegar by metabolome analysis, gas chromatography/mass spectrometry, and sensory attribute evaluation. Vinegar affected metabolism during tempe fermentation, which led to altered metabolite profiles in the final product. We validated the metabolite profiles of two types of tempe using triangle tests and rate-all-that-apply (RATA) tests, which revealed that the sensory attributes of a golden-brown color, ammonia smell, pleasant smell, salty flavor, and acceptance significantly differed (p < 0.05) between the two types of tempe. A high concentration of specific amino acids in the control tempe explained a strong ammonia smell, saltiness, and darker golden-brown sensory attributes. Tempe soaked in vinegar contained high concentrations of metabolites associated with a roasted aroma and cooked meat. In conclusion, most RATA panelists who were being introduced to tempe preferred that soaked in vinegar to the control that was not.

This study aimed to evaluate the capability of horizontal subsurface flow constructed wetlands (HSFCWs) in treating contaminated wastewater with a high concentration of polycyclic aromatic hydrocarbons (PAHs) (Phenanthrene, Pyrene, and Benzo[a]Pyrene), using two plants, namely Phragmites and Vetiver. The investigated parameters were (1) PAHs uptake by the plants, (2) PAHs removal efficiencies, (3) accumulated PAHs in the soil of CWs, (4) shoot/root concentration factor, (5) translocation factor, and (6) PAHs correlation to lipid contains in the plants. During the treatment period, the results showed that the highest concentration of Phenanthrene in the shoot and the root systems of Phragmites, was 229.3 and 192 μg/g; Pyrene was 69.1 and 59.2 µg/g; and Benzo[a]Pyrene 25.1 and 20.2 µg/g, respectively. Meanwhile, in the Vetiver shoot and root systems were Phenanthrene 87.5 and 64.1 µg/g; Pyrene 63.2 and 42.1 µg/g; and Benzo[a]Pyrene 21.3 and 27.3 µg/g, respectively. The removal rates of Phenanthrene, Pyrene, and Benzo[a]Pyrene (PAHs compounds) by the CW planted with Phragmites were found to be 83%, 71%, and 81%, respectively, while the removal rates by CW planted with Vetiver were found to be 67%, 66%, and 73%, respectively. Moreover, the removal rates by unplanted CW were found to be 62%, 58%, and 55%, respectively. The results indicated that the HSFCW planted with Phragmites has an effective pathway to remove high concentrations of PAHs.
