Alternative Ecological Risk Assessment

In Alternative Ecological Risk Assessment the author, Lawrence V. Tannenbaum, provides a critical review of current practices in the ecological risk assessment field and proposes alternatives that are supported by established science and keen observation. It is hoped that this approach will pave the way to a greater understanding of what appropriate and useful ecological assessment for contaminated sites should entail. He demonstrates that in most cases current practices do not provide for an assessment of ecological risk, and moreover, that endeavoring to assess ecological risk is actually an unnecessary undertaking at conventional hazardous waste sites. (He states, for example, that the concept of scale is often ignored by practitioners, questions why animals like deer are routinely assessed at 5-acre sites, and challenges the ecotoxicology data currently used.)

The book is aimed at students and professionals in the fields of environmental science, ecology, ecotoxicology, and health risk assessment.

Lawrence Tannenbaum (United States Public Health Command, Aberdeen Proving Ground, Maryland, USA) is a certified senior ecologist and a full-time health risk assessor working for the U.S. Army, with a previous (Superfund Program) history at the U.S. Environmental Protection Agency. He is the inventor of a patented ecological assessment field-truthing method, and is an associate editor of a Society of Environmental Toxicology and Chemistry journal.
