Digitized edition from print [produced by Environment and Climate Change Canada]. Includes bibliographical references (pages 13-15). "Procedures for the extraction of sediments, suspended sediments or suspended particulates for toxicity and genotixicity studies are becoming increasingly more complicated, time consuming and expensive. The original concept of using short-term bioassays was to quickly, efficiently and inexpensively test water, sediments, and suspended sediments for toxicant/genotoxicant responses, in order that samples could be prioritized for the more costly chemical analyses. In this report we describe an extremely simple procedure, the direct sediment test procedure (DSTP) which can be used with the Toxi-chromotest and SOS-Chromotest to test sediments or suspended sediments/particulates for the presence of toxicants or genotoxicants"--Management perspective.
