“…The importance of understanding sedimentation patterns in estuaries when evaluating the distribution of contaminants is underscored by research on sediment contamination conducted in estuary and river systems with known contamination issues (Olsen et al, 1978(Olsen et al, , 1993Ankley et al, 1992;Steuer et al, 1995;Hirschberg et al, 1996). The sedimentation characteristics we observed in our three study reaches are likely related to numerous physical, chemical and biological factors that can affect estuarine sedimentary processes and patterns (Olsen et al, 1978).…”

• We modeled sedimentation patterns in three reaches in the Columbia River Estuary.• Sediment transport model is used to guide bottom sediment sample allocation.• Organic carbon levels are correlated with predicted sedimentation patterns.• Sediment contaminants are correlated with predicted sedimentation patterns.• Longitudinal contaminant trends comport to trends in resident bird and fish tissues. While previous studies have documented contaminants in fish, sediments, water, and wildlife, few specifics are known about the spatial distribution of contaminants in the Columbia River Estuary (CRE). Our study goal was to characterize sediment contaminant detections and concentrations in reaches of the CRE that were concurrently being sampled to assess contaminants in water, invertebrates, fish, and osprey (Pandion haliaetus) eggs. Our objectives were to develop a survey design based on sedimentation characteristics and then assess whether sediment grain size, total organic carbon (TOC), and contaminant concentrations and detections varied between areas with different sedimentation characteristics. We used a sediment transport model to predict sedimentation characteristics of three 16 km river reaches in the CRE. We then compartmentalized the modeled change in bed mass after a two week simulation to define sampling strata with depositional, stable, or erosional conditions. We collected and analyzed bottom sediments to assess whether substrate composition, organic matter composition, and contaminant concentrations and detections varied among strata within and between the reaches. We observed differences in grain size fractions between strata within and between reaches. We found that the fine sediment fraction was positively correlated with TOC. Contaminant concentrations were statistically different between depositional vs. erosional strata for the industrial compounds, personal care products and polycyclic aromatic hydrocarbons class (Indus-PCP-PAH). We also observed significant differences between strata in the number of detections of Indus-PCP-PAH (depositional vs. erosional; stable vs. erosional) and for the flame retardants, polychlorinated biphenyls, and pesticides class (depositional vs. erosional, depositional vs. stable). When we estimated mean contaminant concentrations by reach, we observed higher contaminant concentrations in the furthest downstream reach with a decreasing trend in the two upstream reaches. Contaminant survey designs that account for sedimentation characteristics could increase the probability that sampling is allocated to areas likely to be contaminated. a b s t r a c t a r t i c l e i n f oPublished by Elsevier B.V.

“…An elutriate sediment toxicity test, designed to detect the release of chemical contaminants from the sediment suspended in the water column, provides a better measure of the amount of a substance that is exchanged between the sediment and the aqueous phase [29,30]. Cheung et al [31] suggested that the elutriate sediment toxicity test provides a better measure of the bioavailable substances in the sediment.…”

h i g h l i g h t s• Yeast bioassays were used to evaluate the TR disrupting activities of the sediments.• The organic extracts showed TR antagonistic activities.• The elutriates also significantly antagonized the TR.• The causes of toxicity in the elutriates appear to be partly related to the heavy metals. a r t i c l e i n f o a b s t r a c tIn the present study, yeast bioassays were used to evaluate and characterize the thyroid receptor (TR) disrupting activities of the organic extracts and elutriates of the sediments from the Guanting Reservoir, Beijing, China. An accelerated solvent extraction was used to separate the organic extracts, which were subjected to a yeast bioassay. The organic extracts could affect thyroid hormone signaling by decreasing the binding of the thyroid hormone. The TR antagonistic activity equivalents (TEQ bio ) referring to amiodarone hydrochloride were calculated and the observed TEQ bio-organic extracts ranged from 25.4 ± 3.7 to 176.9 ± 18.0 g/g. Elutriate toxicity tests using the modified yeast bioassay revealed that the elutriates also significantly antagonized the TR, with the TEQ bio-elutriates ranging from N.D. to 7.8 ± 0.8 g/L. To characterize the toxic compounds, elutriates were extracted by using a C18 cartridge or treated with ethylenediaminetetraacetic acid (EDTA, 30 mg/L). The results suggested that the addition of EDTA eliminated over 74.3% of the total effects, and the chemical analysis revealed that heavy metals, some of which exhibited TR disrupting potency, for example Zn and Cd, were detectable with higher concentrations in the elutriates. Thus, the cause(s) of toxicity in the elutriate appear to be partly related to the heavy metals.

“…This approach thus combines the potential cause (chemistry) with the effect (biology) of degradation resulting from sediment pollution . A more comprehensive, integrated assessment of sediment toxicity has been recently done in the Great Lakes (Ankley et al ., 1992) . It included (1) analysis of benthic community structure, (2) determination of bulk sediment and pore water toxicity to microbial, invertebrate and vertebrate species, (3) identification of specific sediment toxicants, (4) evaluation of the presence of carcinogenic and/or mutagenic compounds in the sediments via microbial and fish assays, (5) determination of possible toxic and/or teratogenic effects of sediment contamination on avian populations, and (6) risk assessement for several contaminants of specific concern in the sediments and associated biota .…”

Benthic metazoans play a key role as test organisms in toxicity analyses of aquatic ecosystems . This report gives an overview of the species of benthic metazoans used for the assessment of toxicity in freshwater and marine sediments, as well as of the criteria relevant to the choice between test species and procedures . The main applications of these organisms are mono-species bioassays, test-batteries, analyses of benthic communities and bioaccumulation studies . Sediment toxicity assays, including acute and chronic exposures, have been developed for nematodes, insects, oligochaetes, polychaetes, crustaceans, molluscs and echinoderms . At least 30 species of freshwater and 71 species of marine and estuarine benthic metazoans have thus far been used in sediment toxicity bioassays . Although aquatic pollution is a world-wide problem, most sediment toxicity bioassays have been developed for organisms native to Europe and North America . The most common bioassay endpoints are mortality, development, growth and behavioural responses . The value of genetic, biochemical, physiological and pathological responses as toxicity endpoints is currently being investigated . The quest for additional test species and protocols is still a worthwhile endeavour in sediment ecotoxicology . Abstract 215Introduction 215
