[16] p. NWRI contribution ; no. 86-174 Digitized edition from print [produced by Environment and Climate Change Canada]. Includes bibliographical references. "The suitability of a variety of biochemical, microbiological and bioassay tests to become part of a battery of test procedures to identify degraded or degrading sediments and waterbodies are evaluated in this report. Data were obtained from 40 river (Detroit and Niagara) and inshore Lake Erie sampling sites. These data indicate that microbial population, biochemical or bioassay tests performed independently do not provide realistic estimates of priority concern areas and that the battery approach is necessary"--Abstract.
