“…Lipophilic contaminants are mainly bound to the organic and fine fraction of the sediments, which is also the fraction of the sediment selected by sediment-feeding organisms [17,18]. Sediment characteristics will have had some influence also.…”

In order to assess the importance of the mode of feeding for the bioaccumulation of contaminants from sediments, three marine benthic invertebrates, with different feeding habits, were exposed to contaminated sediments in outdoor mesocosms. Residue analyses were carried out for several polychlorinated biphenyls and polycyclic aromatic hydrocarbons after exposure periods of 60 to 140 days. It was shown that sediment ingestion is a major uptake route for the sediment‐feeding lugworm, Arenicola marina, and for the facultative deposit‐feeding baltic tellin, Macoma balthica. Residues in the filter‐feeding mussel, Mytilus edulis, appeared to be independent of contaminant concentrations in the sediment. The difference between deposit and filter‐feeding bivalves was confirmed in experiments involving the baltic tellin, with differences in the food availability in the overlying water. A simple linear regression model was used to describe contaminant concentrations in sediment‐feeding invertebrates as a function of concentrations in sediment. A correction for the accumulation from water was made by subtracting the concentrations in filter feeders. It was concluded that chemical equilibrium partitioning alone is not sufficient for the assessment of the risks of contaminated sediments to sediment‐feeding invertebrates, but that feeding habits should also be considered.

“…Organisms that ingest contaminated sediment may assimilate contaminants from ingested sediment Lee et al 1990;Landrum and Robbins 1990). In this sense, benthos have the important function of removing contaminants from storage in sediment and introducing contaminants into the food chain (Reynoldson 1987;Baudo and Muntau 1990).…”

“…This indicates that mussels at the deep site with lower food availability concentrate PCBs more, probably by feeding on particulate matter with a higher PCB content compared with the SPM, which is reflected in the slightly higher sum PCBi concentrations in the mussel faeces compared with the SPM. Food selection has earlier been suggested to increase contaminant exposure to depositfeeding bivalves (Lee et al 1990) and sediment-feeding oligochaetes (Klump et al 1987). This feeding behaviour of the mussels will also increase the biodeposition rate of PCBs relative to the gross sedimentation rate.…”

Biodeposits of the blue m.usse1 bfyWus edulis and pelagic and near-bed settling particulate matter were collected in situ over a 1 yr period in a coastal area of the Northern Baltic proper. The amounts of carbon and PCBs (polychlorinated biphenyls) in the collected biodeposits were compared to those in pelagic and near-bed settling material and rates of carbon and PCB biodeposition by mussels were estimated. The filter-feeding activity and subsequent release of faecal matter by the mussels increased gross sedimentation of carbon to benthos by 45% if compared to areas with no mussels. By selectively feeding on particles rich in organic carbon the mussels also concentrated associated contaminants and thereby increased gross sedimentation of PCBs by 5 0 " ' . This suggests that mussel biodeposition will enhance the availabil~ty of PCBs to benthic deposit feeders Livlng in or in the vicinity of mussel beds. Extrapolahon of the experimental results to the total Swedish coastal zone of the Baltic proper indicates that mussel biodeposition is responsible for a significant part of PCB net sedirnentation, i e. 17 % or 96 kg yr-' Consequently, even when seen from a large geographical scale, mussels are important modifiers of PCB cycling by directing considerable amounts of PCBs towards the benthic food web and thereby influencing the retention time of these and probably many other contaminants in the coastal zone. It is also likely that changes in mussel biornass, for example owing to shifts in primary production or salinity, w~ll markedly affect the transport and fate of contaminants in the Baltic Sea.
