“…On the other hand, during long-term contact between PAHs and sediment particles, PAHs become tightly bound to organic phases in the sediment, reducing their bioavailability (Neff 2002). Levels of BCF confirm that those PAHs that present logKow values of 5-6 show the highest accumulation potential as reported in previous studies (Kaag et al 1997;kaag et al 1998;Rust et al 2004a).…”

“…Uptake of hydrophobic compounds from ingested material has been reported as a major contributor to an animal's total body burden of toxicants (Kaag et al 1996;Kaag et al 1998;Penry and Weston 1998;Selck et al 2003). Also bioaccumulation studies have shown that lugworms accumulate organic contaminants to higher concentrations than filter feeding animals (Kaag et al 1997).…”

The present study was conducted to evaluate a sediment toxicity and bioavailability test with the polychaete Arenicola marina as a potential tool to assess sediments contaminated by oil spills. A bioassay using the lugworm Arenicola marina was carried out in order to determine toxicity and bioaccumulation associated with the contaminants present in the fuel oil extracted from a sank tanker. After 10 and 21 days of exposure to sediments with different proportions of fuel oil (0.5, 1, 2, 4 and 8%) polychaetes were sampled to determine the mortality and the levels of individual PAHs in the organisms. During the experiment, mortality was recorded and the concentration (percentage of fuel oil) that provokes the mortality of the 50% of the Arenicola marina population exposed was calculated for both sampling dates (LC50(10) = 6.4%; LC50(21) = 2.4%). Bioaccumulation was mainly produced for fluoranthene, pyrene, benzo(b)fluoranthene and benzo(k)fluoranthene, whereas phenantrene and anthracene where initially accumulated and then metabolized. The results obtained in the present study suggest Arenicola marina can be a suitable species for assessing PAHs toxicity and bioaccumulation as part of oil spill management.

“…Different pollution gradients are known to exist along the Western Scheldt, with increasing levels of heavy metals and volatile compounds toward the canal of Ghent-Terneuzen and the harbor of Antwerp, suggesting high inputs of anthropogenic discharges into the aquatic ecosystem through this river system [2,23,24]. In a previous study about the Western Scheldt, a PFOS pollution gradient in liver of bib (Trisopterus luscus) and plaice (Pleuronectes platessa) has been suggested [20].…”

Over the past decades little research has been conducted on the environmental behavior and effects of fluorinated organochemicals (FOCs). Recently it has been reported that perfluorooctane sulfonic acid (PFOS) is occurring worldwide. Little is known about the PFOS levels in organisms originating from the southern North Sea and the Western Scheldt estuary. In this study, we determined, for the first time, the PFOS-exposure levels in Crangon crangon, Carcinus maenas, and Asterias rubens from these ecosystems. Concentrations on a wet-weight basis in soft tissues of shrimp, crab, and starfish ranged from 19 to 520 ng/g, from 24 to 877 ng/g, and from 9 to 176 ng/g, respectively. These results show the existence of a PFOS pollution gradient in organisms along the Western Scheldt estuary, with the highest concentrations near Antwerp. The range of PFOS levels in shrimp and crab are slightly higher in coastal regions compared with sampling sites in open water. This study shows widespread distribution of PFOS in the Belgian and Dutch marine and estuarine environment at rather high concentrations.

“…In the laboratory, all biota samples were placed overnight in filtered freshwater without sediment to empty gut, without eliminating hydrophobic contaminants. The following morning, all animals were blotted dry and stored at −20 • C before further processing [20,21]. Information on shellfish length, weight and lipid content is given in Table 1.…”
