What is considered perhaps the northwest's most valuable natural resource will be the primary focus for hundreds of environmental science professionals as they convene for the Fourth Society of Environmental Toxicology and Chemistry World Congress conference in Portland this November.

Among the events designed to exchange ideas and present research will be an Interactive Poster Session entitled, Investigations of the Columbia River and Estuary led by several Pacific Northwest National Laboratory scientists. On Thursday, November 18, PNNL will deliver presentations addressing river research:

• Dredge entrainment of Dungeness crab in the Columbia River Estuary Greg Williams, PNNL's Marine Research Operations, Sequim, WA, will address loss estimates of Dungeness crab as a result of ongoing maintenance dredging and proposed deepening of the Columbia River Estuary navigation channel. This research also has an adaptive management focus that involves developing models that relate crab entrainment rates to seasonal patterns of bottom salinity, and which may yield dredging strategies that reduce these losses.

• Screening Columbia and Willamette River Sediments for CYP1A-Inducing Compounds with a Biomarker Assay (EPA 4425) Jack Anderson, PNNL's Sequim Marine Research Operations, Sequim, WA, will report on the results found by sampling Columbia River and Willamette River sediments. While most samples revealed background or low-levels of toxic compounds, some of the Willamette sediments showed elevated levels where biological effects would be expected.

• Assessments of onsite ecological impacts of legacy materials from the Hanford Site, Washington State during the 21st century Brett Tiller, Pacific Northwest National Laboratory Scientist, reports how the Department of Energy is assessing the health of biota that inhabit the Hanford Site in southeastern Washington State.
