“…However, large variations in population densities are common between areas (Perus & Bonsdorff 2004). This variation should be taken into consideration when interpreting the results, since bioturbation intensity has been positively correlated with both size and abundance of infauna (Reible et al 1996, Sandnes et al 2000.Input of labile OM can increase the mobilisation of contaminants from the sediment surface. This may be the result of a combined effect of increased animal feeding and bioturbation activity, and a high diagenetic release due to OM degradation.…”

This experimental study examined the interactive effects of bioturbation and settling organic matter (OM) on the fate (burial and remobilisation) of 2 surface-deposited contaminants in Baltic Sea sediment: the metal Cd and a hydrophobic organic pollutant, the flame retardant BDE-99. Three macrofaunal species with diverse feeding and bioturbation strategies were used: the amphipod Monoporeia affinis, the clam Macoma balthica and the polychaete Marenzelleria spp. Radiolabelled contaminants were added to the sediment surface in association with 3 different OM types: (1) phytoplankton, (2) terrestrial lignin and (3) Baltic sediment. Bioturbation by all species increased the retention of both contaminants in the sediment, most effectively M. affinis and M. balthica. A decoupled transport of Cd and BDE-99 by Marenzelleria was observed. Generally, Marenzelleria buried the highest amount of Cd into the sediment but also caused the highest remobilisation to the water, indicating an effective transport of (soluble) Cd over the sediment -water interface via bioirrigation. Lack of the highly hydrophobic and mainly particle-associated BDE-99 below the sediment surface suggests that Marenzelleria caused no significant particle mixing. The addition of various OM types significantly affected the distribution of Cd, but not of BDE-99. There was an interactive effect between bioturbation (species) and OM type, generally showing an increased burial and release of Cd when associated with phytoplankton in the presence of Marenzelleria. Our results emphasise the importance of understanding the complex interactions between ecological (e.g. infaunal feeding and bioturbation activities) and physiochemical processes (contaminant speciation and sorption kinetics) when assessing the fate of contaminants in aquatic ecosystems.

Bioirrigation, on the other hand, increases the flux of solutes, i.e. dissolved compounds in the pore water and over the sediment -water interface (Aller & Aller 1998). The partitioning of a contaminant between the solid and water phase in sediments depends on the contaminant's inherent properties and the biogeochemical state of the sediment. Hydrophobic organic contaminants (HOCs) preferentially adsorb to particulate OM in sediments, and their distribution between phases generally can be calculated based on the physiochemical properties of the compound, such as water solubility and lipophilicity, and the amount of OM in the sediment (Schwarzenbach et al. 2003). The partitioning of metals is strongly affected by the sediment chemical environment, such as pH, redox conditions and the presence of other chemical species (Chapman et al. 1998).

“…Bioturbation by conveyor-belt feeders is achieved by the continuous movement of buried sediment particles to the surface through ingestion and defecation processes, resulting in considerable amounts of contaminants being transported to the sedimentwater interface (Green and Chandler, 1994;Karickhoff and Morris, 1985;Koelmans and Jonker, 2011;Reible et al, 1996). For instance, the presence of Tubificid oligochaetes in sediment increased HOC concentrations in overlying water 4-6 folds (Karickhoff and Morris, 1985).…”

“…Additionally, the activities of organisms also affect the fate, transport, and bioavailability of sediment-associated contaminants (Green and Chandler, 1994;Reible et al, 1996;Thibodeaux and Bierman, 2003). Oligochaetes have been frequently used as the model organisms to study bioturbation, as they have been noted as organisms that highly contribute to the bioturbation in freshwater systems (Bosworth and Thibodeaux, 1990;Thibodeaux and Bierman, 2003).…”

“…Accordingly, the sludge conveyed to the settling pond is usually removed once a year, which means that the sludge might be subjected for a long period not only to resuspension and/or hydrolysis by bacteria, but also to other biological activities such as bioturbation. Bioturbation carried out by benthic organisms (such as chironomid laravaes or tubificid worms) is defined as the sediment processing by animals during burrowing, sediment ingestion/defecation, tube building and biodeposition (Reible et al, 1996). As a result of bioturbation the sediment particles and pore water is subjected to a vertical and horizontal movement that leads to the mixing of upper sediment surface (Robins et al, 1979;Robins, 1982).…”
