OPTIONS FOR SEDIMENT TIEs – THE STATE OF THE SCIENCE
Abstract:Laboratory Toxicity Identification Evaluation (TIE) studies are designed to characterize and identify the constituent(s) toxic to aquatic life. For sediments, this can have application in risk assessments of contaminated sites and in assigning remediation liability. A key component of such assessments often involves determining the role of natural toxicants in the observed toxicity. USEPA TIE methodologies for effluents have been available since the late 1980s. However, TIE protocols for sediment-associated toxicants, particularly whole sediments, are much less established than TIE methods for effluents. This poster reviews the state-of-the-science in sediment toxicant identification, highlights notable research, and provides insight into what the EPA sediment TIE manual will contain when it is released in 2005.
