Abstract:
It is clear that there are relatively few data available on the effect of particulate copper on aquatic communities in either rivers or estuaries, most information being on the effect of soluble copper in the water column. Furthermore, up to the year 1984 at least, no study appears to have defined sediment quality criteria for individual toxicants in fresh-water (Cairns et al., 1984). More recently, however, standards have been proposed based on the 'equilibrium partitioning approach' whereby the concentration of copper in the interstitial water is restricted to the concentration that would be acceptable in the overlying water (Pavlou, 1987); for example, a safe level of 68 mg Cu/kg is proposed, based upon an organic carbon content of 2% and is similar to historical limits of 250-50 mg Cu/kg developed for the Great Lakes.
The related, and relevant subject of the chemistry of copper in sediments and in the overlying water has already been discussed elsewhere in detail, e.g. by Hunt (1982) and Salomans (1987) and is, therefore, not dealt with here, although it is referred to in passing. Suffice it to say that the biological effects of copper in sediment hinge upon the bio-availability of the metal and that this is not readily amenable to direct measurement other than by measuring the responses of the organisms involved; the problem has been recently reviewed (Campbell et al., 1988).
The approach adopted in this report is to present a critical summary of each paper in turn and to draw the more general conclusions later. Unless otherwise stated, concentrations of copper are expressed as mg Cu/kg dry weight in both sediment and organisms.
