It is very difficult to estimate the hazardous effects of toxicants because they interact each other in additive, synergistic, and antagonistic ways. Bioassay is an approaching method for toxicity evaluation of actual or potential danger in hazardous wastes. This study is to evaluate the susceptibility of 3 water fleas and luminescent bacteria Photobacterium Phosphoreum to heavy metals. The toxcity test is performed against 7 heavy metals. For water fleas, Hg shows the highest toxicity and Fe shows the lowest toxicity by the 24 or 48 hour LC_(50). For luminescent bacteria, by the 5min EC_(50) Hg is more toxic than any other metals. M. macrosopa and D. psittacea have a good reproductivity in the laboratory and show the possibility as an aquatic toxicity test organism.
