Abstract
Multi-media/multi-trophic level bioassays have been proposed to determine the extent and severity of environmental contamination at hazardous waste sites. Comparative toxicological profiles for algae, daphnia, earthworms, microbes, mixed sewage and plants; wheat 'Stephens', lettuce, butter crunch, radish, 'Cherry Belle', red clover, 'Kenland', and cucumber, 'Spartan Valor' are presented for selected heavy metals, herbicides and insecticides. Specific chemical EC50 values are presented for each test organism. Differences in standard deviations were compared between each individual test organism, as well as for the chemical subgroup assayed. Algae and daphnia are the most sensitive test organisms to heavy metals and insecticides followed in order of decreasing sensitivity by Microtox, DO depletion rate, seed germination and earthworms. Differences in toxicity of 2,4-D chemical formulations and commercial sources of insecticides were observed with algae and daphnia tests.
