  • Trace metal status in marine biological samples: a review

    The literature on trace metal status in marine biological samples is reviewed, taking into account the importance of the subject. Marine organisms accumulate trace metals to body concentrations well above those in seawater. Different marine organisms differ significantly in accumulated tissue and total body concentrations of heavy metals. The present literature survey indicates that more than 26 ...

  • The analysis of polycyclic aromatic hydrocarbons in marine samples

    Polycyclic aromatic hydrocarbons (PAH) have been determined in marine samples for many years, but have only rarely been included in either national or international monitoring programmes. PAH can arise in the environment from natural sources, oil and petroleum products and combustion processes. Although oil spills influence PAH concentrations in local areas, the major sources of PAH are ...

  • Application of passive sampling for measuring dissolved concentrations of organic contaminants in the water column at 3 marine superfund sites

    Currently, there is an effort under way to encourage remedial project managers at contaminated sites to use passive sampling to collect freely dissolved concentrations (Cfree) of hydrophobic organic contaminants to improve site assessments. The objective of the present study was to evaluate the use of passive sampling for measuring water column Cfree for several hydrophobic organic ...

  • A New Microbial Contact Assay for Marine Sediments

    The number of microbiological contact tests for marine sediments is low, although microorganisms enable a rapid screening and monitoring of sediment quality and a high resolution of hazard assessment. As no single biotest can provide reliable answers concerning the potential hazard of environmental samples, a combination of bioassays needs to be applied to serve this purpose. In order to cover ...


  • Determination of Clay Size Fraction of Marine Clays

    This technical note describes a study on the effect of different dispersing agents and the quantity of same on the grain-size distribution and in particular the percentage of clay size. The results confirm that the existing practice of using 100 mL of standard dispersing agent, viz. sodium hexametaphosphate and sodium carbonate solution, is suitable for marine clays also. The clay size fraction ...

  • Measurement of TOC in High-Salt Sample

    The quantity of organic matter in seawater is important in the research and monitoring of marine pollution as an indicator of organic pollution. The salt content in seawater is typically about 3.5 %, but using the Shimadzu total organic carbon analyzer, it is possible to measure the TOC directly without dilution or other pretreatment procedures. Here, we introduce an example of measurement of ...

  • Interviews: Ken Buesseler, Researcher into marine discharges at Fukushima

    We as scientists do have a responsibility and I hope to be able to contribute in some way“ Ken Buesseler, researcher at the Wood Hoods Oceanographic Institute is investigating the radioactivity leaked from the Fukushima nuclear power station, initially from data facilitated by the TEPCO (Tokyo Electric Power Company) and then from samples gathered in situ. He believes that official bodies ...

  • Characterising and identifying toxicants in marine waters: a review of marine toxicity identification evaluations (TIEs)

    One impact of human activity is contamination of the world’s oceans with toxic pollutants. Marine toxicity identification evaluation (TIE) technology provides an approach for characterising and identifying the causes of toxicity in aqueous and sediment samples. This review describes the evolution and use of marine TIEs since their initial development approximately fifteen years ago. Currently, 30 ...

  • Speciation of butyltin compounds in marine sediments and sea-shells by HG/GC/QFAAS

    After optimisation of sample pretreatment and determination procedures, butyltin compounds were determined in selected marine sediments and biota using the hydride generation/gas chromatography/quartz furnace atomic absorption spectrometry method. Butyltins were detected in all surface sediment samples of Arcachon Bay, though at widely different concentrations (from a few ng g-1 in remote areas ...

  • Detection and phylogenetic analysis of hepatitis A virus and norovirus in marine recreational waters of Mexico

    An investigation was conducted to determine hepatitis A virus (HAV) and norovirus (NV) presence in marine recreational waters (MRWs) from two Mexican tourists beaches (Altata and Mazatlan), located at the northwestern state of Sinaloa, Mexico. Also, Binary Logistic Regression (BLR) analyses were conducted between physicochemical parameters (temperature, turbidity and salinity) and viral organisms ...

  • The inter-tidal zone is the pathway of input of enterococci to a subtropical recreational marine beach

    Efforts were made to evaluate the source of enterococci levels at a recreational beach. Four monitoring efforts were implemented which included tidal studies, hourly sampling, runoff sampling, and spatially intensive sediment sampling. Spatially intensive sediment sampling indicated that enterococci concentrations consistently decreased away from the inter-tidal zone, both seaward and landward. ...

  • Marine specimen banking: archive and pollution control for the 21st century

    The oceans have in the past been extensively used as disposal sites for various kinds of waste. The world ocean – being the final sink for many natural and anthropogenic substances – is a "labile" ecosystem, which is and has for a long time been the focal point of extensive interdisciplinary research. Measurements of heavy metals and a suite of various chemical compounds in the marine ...

  • Contaminants of emerging concern in municipal wastewater effluents and marine receiving water

    The occurrence and concentrations of contaminants of emerging concern (CECs) were investigated in municipal effluents and in marine receiving water. Final effluent from four large publicly owned treatment works (POTWs) and seawater collected near the respective POTW outfall discharges and a reference station were collected quarterly over one year and analyzed for 56 CECs. Several CECs were ...

  • Laboratory Properties of a Soft Marine Clay Reinforced with Woven and Nonwoven Geotextiles

    This paper is concerned with the laboratory properties of a geotextile-reinforced compacted soft marine deposit with respect to its compaction, compressive strength, and time-dependent settlement characteristics. Two different geotextiles, namely, Polyfelt TS-500 (nonwoven) and Cardon SG PP 150 (woven) have been investigated. It was observed from the experimental study that a nonwoven geotextile ...

  • Marine sediment components: identification and dispersal assessed by diffuse reflectance spectrophotometry

    Analysis of deep-sea sediments presents a number of exceptional challenges. Generally, the amount of material available is small and has to be shared among investigators. Also, deep-sea sediment contains a diverse range of components from a variety of sources including lithogenous, biogenous and hydrogenous. Finally, large number of samples is frequently analysed making rapid analysis a ...
