This short course is intended for risk
assessors who are already familiar with ecological risk assessment guidance and
procedures. It is designed to provide a comprehensive overview of available
techniques and is composed of three segments: 1) field surveys for ecological
characterization and biomonitoring, 2) field sampling and assessment of
bioaccumulation, and 3) laboratory and field-testing methods. Within each
section, why a particular tool is chosen, what information it provides, what its
cost is, how the information can be used, and whether the information can be
used to answer more than one question in the site investigation will be
discussed. The background, development, and current state of the art for each
technique will be presented, with at least one third of each session devoted to
problem solving and case examples to illustrate a tool's utility and regulatory
acceptance. To provide a balance in perspective, instructors will include
representatives from both the industrial and regulatory sectors. Designed for
advanced scientists who are, or will be involved in developing field-sampling
plans for ecological risk assessments, this course is to provide an advanced
level overview of techniques available to generate data for ecological risk
assessments.
