Description:
This paper synthesizes several presentations on the use of indicators in elological risk assessments for persistent, bioaccumulative toxicants (PBTs). The presentations were organized around two chemical case studies: 1) mercury, and 2) compounds that exhibit an Ah-receptor based mode-of-action. Presenters summarized the current practice of ecological risk assessment for these compounds and described research on known or suspected impacts. In addition, this paper addresses three special topics that apply broadly to all PBTs: 1) the convergence of ecological assessment and ecological risk assessment, 2) integration of ecological and human health risk assessment, and 3) risk assessments for population-level effects.
