Abstract
Granulated fly ash, one of recycled material, has been used as covering sands to improve sediment quality in enclosed coastal areas of Chugoku District. In the present study, in addition to reveal heavy metal contents of granulated fly ash, safety of the materials was examined using snails and bivalves in both laboratory experiments and field experiments. In the all experiments, bioaccumulation of heavy metals was not observed. Further, the heavy metal accumulation was lower in the body of animals used in the experiments than those sold in market. It was concluded that granulated fly ash is safety recycle material in terms of heavy metals for benthic animals.
