A Computerized Procedure for Predicting Plant Uptake of Heavy Metals from Contaminated Freshwater Dredged Material

Abstract : The Decisionmaking Framework (DMF) developed by Peddicord et al. (in preparation) provides a framework for evaluating sediments before dredging. This framework is made up of several modules, one of which is the plant bioassay for materials proposed for upland or wetland placement. Like the DMF, the plant bioassay module is based on tiered testing. Tier I Is a computer simulation based on chemical extraction of test and reference sediments; Tier II is an actual laboratory/greenhouse plant bioassay. The purpose of this note is to briefly describe development and use of the computer simulation on a personal computer (PC).
