Influence of suspended solids on bioavailability of hexachlorobenzene and lindane to the deposit-feeding marine bivalve, Abra nitida (Mueller)
It is well-known that suspended solids in water adsorb hydrophobic pollutants, thereby decreasing the bioavailability of the compounds to aquatic organisms which do not use the particles as food. It is also known that hydrophobic pollutants deposited in sediments usually have a low bioavailability. The relative contribution of water and sediment respectively to bioaccumulation of hydrophobic pollutants has been discussed in many papers based on field data, but the conclusions are uncertain. However, very few studies have been performed under controlled conditions in the laboratory on how the bioaccumulation of such compounds dissolved in the water is changed by adsorption to particles when these particles are used as food by the organism. This has now been investigated using the deposit-feeding bivalve Abra nitida which was exposed to hexachlorobenzene and lindane by means of a new method for dosing of hydrophobic compounds to a continuous flow system in long term tests.
