This book is derived from a symposium sponsored by the American Chemical Society (ACS) Division of Environmental Chemistry. "Environmental Chemistry: Emphasis on E P A Research and E P A Sponsored Research," which was organized for the A C S National Meeting in Washington, D.C., August 2 0 24, 2000. The goal of the symposium was to highlight this U.S. Environmental Protection Agency (EPA) research and to foster the exchange of information among research groups. Papers were solicited with a call for papers, as well as direct contacts with grantees. The identification of E P A research goals is guided by Goal 8 of the 1993 Government Performance and Results Act, to apply sound science for improved understanding of environmental risk, along with state-of-the-art scientific knowledge and methods to detect, abate, and avoid environmental problems. Increased availability of environmental measurements and models for extending these data permit assessing environmental exposures and potential risks posed by contaminants, particularly to children. How these goals are expressed each year with respect to internal research and new grant solicitations reflects both long term, as well as new priorities that arise, given the demands placed upon a regulatory agency. The symposium consisted of 32 oral presentations in 5 half-day sessions, and an evening poster session with 15 additional papers. The structure of the symposium followed from the major topics identified in the original call for 1

papers, and a need to divide these up accordingly. The oral presentation sessions were entitled: Soil/Sediment: Fate and Transport: Parts 1 and 2; Atmospheric Fate and Transport; Environmental Impacts and Monitoring; and Remediation: New Methodologies. The poster session included papers specifically requested to be posters, as well as those outside the scope of these major topics. Following the symposium, the A C S Division of Environmental Chemistry encouraged Robert L . Lipnick to develop the presented papers as an A C S Symposium Series volume. Three of the symposium participants (Robert L . Mason, Margaret L . Phillips, and Charles U . Pittman, Jr.) agreed to participate as editors, each applying specific expertise to papers derived from symposium sessions in which their oral presentations were given. With this approach, a book proposal was reviewed and approved by the A C S Books Department. Pittman has expertise in chemical remediation treatments and organic chemistry. Mason has expertise in the fate and transport of inorganic chemicals, and especially heavy metals, in the atmosphere and in aquatic systems. Phillips' research interests focus on human exposure assessment. Lipnick has expertise in the correlation of chemical structure with physicochemical properties, quatitative structure-activity relationship (QSAR), and molecular mechanism of toxic action. Chapters were recruited from the symposium's oral presentations and from poster presentations, as well as from specialized authorities to fill gaps. In structuring the book the chapters derived from the sessions Soil/Sediment: Fate and Transport: Parts 1 and 2 as well as Atmospheric Fate and Transport were grouped together, organizing the book into the following three sections: (1) Fate and Transport in Soil/Sediment, Waters, and Air; (2) Environmental Impacts and Monitoring; and (3) Remediation, reflecting the original session themes. Within each section of the book, the chapters were arranged first by environmental medium (soil/sediment, waters, air, and biota), with chapters addressing transport between media being placed in intermediate sequence. Secondly, chapters are ordered by breadth of focus, from more general to more specific; and thirdly, by placing chapters on inorganic species before chapters on organic species. In a few cases the chapter has been assigned to a section that doesn't correspond to the session in which the original presentation occurred, because the focus of the chapter differed from the presentation. No single book could ever capture the breadth of E P A ' s research interests and technical regulatory concerns about chemicals in the environment. This is a vast, ever evolving mixture of topics. However, this volume provides a representative sampling of current topics and conveys a sense of recent progress and future directions in the field of environmental science.
