Abstract
The objective of the project was to investigate the effect of long term exposure to low concentrations of trace elements leaching from a nearshore reclamation site containing fly ash from coal fired power plants codisposed with fly ash and bottom ash from municipal incinerators on single species and multispecies systems of organisms. Populations of mussels, eelgrass, zoobenthos in sediment cores and test panels were exposed in a flow through system with natural sea water (9 0/00 salinity) and 6 dilutions of water from a fly ash lagoon (ranging from 2-1000 times). During exposure periods of 30 weeks, respectively 2 weeks for mussels and eelgrass, there was a direct relationship between the water concentration and the accumulation of cadmium, but this was not the case for chromium. The growth of mussels, eelgrass and the qualitative and quantitative development of the macrozoobenthos in the sediment cores was not related to the concentration of trace elements tested. The conclusions are supported by results of field monitoring of mussels and macrofauna inside and outside a fly ash lagoon. On the basis of the project and results of the ongoing monitoring in the field it is concluded that disposal in a nearshore reclamation site may

Biomonitoring is necessary for detecting trace elements at low levels. Mussels and eelgrass are suitable organisms for long term (month) respectively short term (weeks) monitoring. (au) 24 refs.}
