Oil Spills: The Exxon Valdez and other Environmental Impacts
This virtual issue from on the 1989 oil spill of the Exxon Valdez in Prince William Sound, Alaska is being published by SETAC/Wiley-Blackwell as a resource to enhance informed decision-making in the public and private sectors on the environmental effects of the 20 April 2010 oil spill in the Gulf of Mexico.

Managing and Responding to Oil Spills
IEAM brings together a selection of peer-reviewed articles previously published and still relevant to scientists and other respondents to the 20 April 2010 oil spill in the Gulf of Mexico. These articles exemplify the application of science in environmental decision-making, management, and sound approaches to environmental problem solving.

Characterization of Polycyclic Aromatic Hydrocarbon Bioavailability in Estuarine Sediments using Thin-Film Extraction
Christopher J. Golding, Frank A.P.C. Gobas, and Gavin F. Birch
It is well documented that the bioavailability of hydrophobic organic chemicals (HOCs) can vary substantially among sediments. This makes risk assessments based on total sediment concentrations problematic. The present study investigates the application of thin-film solid-phase extraction to measure bioavailable concentrations of phenanthrene i...

The threshold of toxicological concern (TTC) concept proposes that an exposure threshold value can be derived for chemicals, below which no significant risk to human health or the environment is expected. This concept goes further than setting acceptable exposure levels for individual chemicals, because it attempts to set a de minimis value for chemicals, including those of unknown toxicity, by taking the chemical's structure or mode of action (MOA) into consideration. This study examines the use of the TTC concern concept for endocrine active substances (EAS) with an estrogenic MOA. A case study formed the basis for a workshop of regulatory, industry and academic scientists held to discuss the use of the TTC in aquatic environmental risk assessment. The feasibility and acceptability, general advantages and disadvantages, and the specific issues that need to be considered when applying the TTC concept for EAS in risk assessment were addressed. Issues surrounding the statistical approaches used to derive TTCs were also discussed. This study presents discussion points and consensus findings of the workshop.
