The Core Group's recommendations were adopted at the Fourth Session of GEMSI (Curacao, 25-31 March 1982), and it was further decided that, to increase the cost effectiveness of the proposed six-month activity noted above, a detailed report would be given on the results obtained during the preliminary period with respect to identification of individual PCB components by gas chromatography and gas chromatography-mass spectrometry as well as to the distribution of individual components between solution and particulate matter. This is the subject of this publication. The methods described here are also appropriate for the estimation of several other halogenated hydrocarbons in seawater. Some of these compounds appear in the same fraction as PCB (e.g. penta- and hexa-chlorobenzene); for the estimation of more polar components, additional GC-ECD analyses are required. The extracts needed for this purpose require only relatively small additional steps in the separation procedures.

This book provides a risk-based framework for developing and implementing strategies to manage PCB-contaminated sediments at sites around the country. The framework has seven stages, beginning with problem definition, continuing through assessment of risks and management options, and ending with an evaluation of the success of the management strategy. At the center of the framework is continuous and active involvement of all affected parties-particularly communities-in the development, implementation, and evaluation of the management strategy. A Risk-Management Strategy for PCB-Contaminated Sediments emphasizes the need to consider all risks at a contaminated site, not just human health and ecological effects, but also the social, cultural, and economic impacts. Given the controversy that has arisen at many PCB-contaminated sites, this book provides a consistent, yet flexible, approach for dealing with the many issues associated with assessing and managing the risks at Superfund and other contaminated sites.
