  • 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 ...

  • Biological effects of contaminants on marine organisms: the contribution of biotechnology

    One aspect of ecotoxicology concerns the effects of contaminants. Work on this area in the marine field is recent but useful for numerous applications, such as toxicological tests, the evaluation of organism response and the development of networks for the measurement of pollutant effects. In this context, the contribution of biotechnologies and technical advances in modern biology is important. ...

  • 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 ...


  • Marine crude oil transport – global voyage losses

    Paul Harrison, Consultant to the HMC-4A Marine Oil Transportation Database Committee, presents latest findings from analysis of the 2013 data on marine crude oil transport. The Energy Institute (EI) HMC- 4A Marine Oil Transportation Database Committee has been collecting and analysing worldwide oil shipping data for over 20 years and meets twice a year. The 2013 autumn meeting was held in Rio de ...

  • Marine hydrogeology: recent accomplishments and future opportunities

    Marine hydrogeology is a broad-ranging scientific discipline involving the exploration of fluid–rock interactions below the seafloor. Studies have been conducted at seafloor spreading centers, mid-plate locations, and in plate- and continental-margin environments. Although many seafloor locations are remote, there are aspects of marine systems that make them uniquely suited for hydrologic ...

  • 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 ...

  • Marine phanerogams as a tool in the evaluation of marine trace-metal contamination: an example from the Mediterranean

    New ways of evaluating the quality of the coastal marine environment in a practical, dependable and cost-efficient manner are continually sought. It would thus appear of some value to make use of bioindicator species that reflect both the average levels and the temporal variations of contaminants at a given site. Owing to their extensive distribution in the littoral zone and the ecological ...

  • 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 ...
