Abstract: Sediment bioaccumulation potential evaluations can be improved by a two-level approach. Chemical analysis of sediment interpreted using phase-activity considerations in first-level evaluations would serve as a screen to separate sediments having low potential for bioaccumulation of neutral chemicals from those having high potential. Level-II evaluation, if considered necessary, could then be accomplished using established biological methods to refine the evaluation made in Level-I. 11 refs.
