Two methods for bioassay of toxic metals were used to analyze landfarm soil bioremediation treatments for petroleum hydrocarbons. The MetPLATE{sup TM} is based on enzyme inhibition in a mutant strain of E. coli by bioavailable metals. The Microtox{sup TM} assay measures the light output of the bioluminescent marine bacteria Photobacterium phosphoreum before and after exposure to a water soluble sample. The effective concentration for 50% was determined for fractions extracted by methylene chloride after 5 and 15 minutes exposure time. In both cases, the toxicity appeared to increase because the decreasing effective concentration means less sample causes the same response. MetPLATE showed an increase in toxicity of the samples before the toxicity decreased on day 187. A treatment with nutrients and Permeox appeared to have the least metals toxicity.
