Includes bibliographical references (pages 8-9). "A qualitative/semi-quantitative direct sediment toxicity testing procedure (DSTTP) using the Toxi-Chromotest kit was developed. This DSTTP has advantages over many other toxicity bioassays in that it is simple, quick, and inexpensive. It does not require any instrumentation and can be easily applied under field conditions. The DSTTP measures the available toxicants of the test sediments, suspended sediments, soil and any other solid wastes without altering the original characteristics of the samples as occurs in extraction and concentration procedures"--Abstract.
