Abstract

Although composite chemical analyses, such as total petroleum hydrocarbonsand total metals, are often used to assess the extent of contamination at an industrial site, it is difficult to relate chemical analyses to the environmental and toxicological effects of soil contamination. Since toxicity is related to contaminant bioavailability and solubility, identification andquantification of leachable contaminants should provide an indication of the environmental hazard of the site contaminants. Experiments were performed to determine the leachability and toxicity of contaminants from a flare pit soil which was extensively contaminated with hydrocarbons, metals and salt. Toxicity bioassays included earthworm mortality (Lumbricus terrestris),seed germination and root elongation (Lactuca sativa and Panicum miliaceumL.), algal growth inhibition (Selenastrum capricornutum) and bacterial luminescence inhibition (Pseudomonas fluorescens). Although this soil would require remediation according to chemically based soil criteria, neither the contaminated soil nor leachate generated from the contaminated soil were particularly toxic.
