Polychaete Worms Increase the Bioavailability of Mercury in Coastal Regions
Tom Sizmur, Nelson O’Driscoll, and João Canário
18 July 2013
Volume 14 Issue 7
Coast RegionsWorms that create burrows in coastal sediments can increase the bioavailability of mercury and methylmercury to other organisms. This is the result reported in a new ET&C Feature Article that presents a study carried out by researchers at Acadia University on the Bay of Fundy mudflats, home to the highest tidal amplitude on Earth. The worms engineer their environment by creating burrows, resulting in a network of microhabitats with altered sediment geochemistry. The sediment in these burrows contains about 50% more available mercury and methylmercury than sediment containing no worms.

chemistryBenign by Design—Replacing Toxic Chemicals
Hans Peter Arp, Knut Breivik and Steven Droge
Finding innovative ways for the next generation of industrial chemicals to be environmentally benign or beneficial was the focus of scientists, industry representatives and regulators attending the SETAC Glasgow session on toxic chemical replacement. This session was focused on innovation that would lead to ways of avoiding future pollution. Arguably, this approach is underrepresented within the SETAC community, where a large focus is on identifying problems with contaminants, rather than avoiding them.

fishMisled by Pollutants: The Infochemical Effect—Aquatic and Terrestrial Ecotoxicology
Ursula Klaschka and Ruediger Berghahn
Aquatic organisms use sophisticated, highly specific and dynamic chemical communication systems. They use these systems, which are driven by “infochemicals,” to orient themselves, detect prey and predators and attract sexual partners. There is strong evidence that anthropogenic compounds may interfere with the chemical communication of organisms in the environment. This effect is called the "Infochemical Effect."

Landscape Landscape Ecotoxicology and Spatially Explicit Risk Assessment
Andreas Focks, Paul van den Brink, Melissa Reed and Mikhail Beketov
Natural ecosystems are often characterised by a high spatial and temporal variability (e.g., patch dynamics) that strongly influences ecological processes and can modify the exposure and effects of toxicants on organisms. While the spatial dimension has gained increasing attention in the exposure assessments in recent years, the effects assessment still largely ignores these aspects despite its relevance for realistic prediction and assessment of effects.

oyster catcher Modelling and Empirical Approaches for Improving the Ecological Realism of Ecotoxicology
Valery Forbes, Virginie Ducrot and Annemette Palmqvist
It is often said that there is not enough ecology in ecotoxicology and that this lack can have unfortunate consequences for environmental risk assessment. In this session, held at the SETAC Europe meeting in Glasgow, we explored how ecological realities influence the fate and effects of chemicals in the environment and the consequences of such for ecological risk assessment.

light bulbClosing the Gap between Academic Research and Regulatory Risk Assessment of Chemicals
Marlene Ågerstrand, Mary Sorensen, José Tarazona and Christina Rudén
There is a need for regulators and researchers to meet and discuss how they can collaborate in order to improve the current risk assessment process. SETAC provides an important platform for such discussions, as was evidenced by the high level of pre-workshop registration.

PNW Chapter membersRegional Spotlight: SETAC North America’s Pacific Northwest Chapter
Maggie Dutch
The Pacific Northwest Chapter (PNW) of SETAC North America hosted their very successful 22nd annual regional chapter meeting in Spokane, Washington, in April. The meeting theme was mining toxicity, a topic relevant to the industrial legacy of eastern Washington, Northern Idaho and Montana and included a tour of historic mining sites with discussion on remediation.

Trina von StackelbergParticipate in the SETAC Global Science Committee
Trina von Stackelberg
The SETAC Global Science Committee enjoys participation from the different geographic units, professional affiliations and expertise found across our diverse membership. It is important to have this diversity represented, particularly with respect to the geographic units, in order to ensure that all viewpoints are adequately captured when it comes time to review Pellston and other workshops, make recommendations for writing and reviewing Technical Issue Papers and provide comments on other issues as requested by the World Council and others.
