Abstract

A literature review of sediment bioassessment was conducted as the first step in the development of a more standardized and ecologically sound test procedure for evaluating sediment quality. Based on the review, the authors concluded that 1) a standardized laboratory bioassessment test should consist of flowthrough exposure of at least 10 days duration using more than one aquatic organism including at least an infaunal benthic invertebrate and a fish species. 2) Before adoption of a laboratory sediment bioassessment procedure, the laboratory results should be evaluated by comparison with field conditions. 3) Most current sediment bioassessment regulatory tests measure acute toxicity or bioaccumulation. Development of tests to evaluate chronic, sublethal effects is needed.
