Contributors Sought for Book on Emergency Toxicology Interested individuals are invited to participate in the production of a special volume entitled "Selected Methods of Emergency Toxicology" to be published by the American Association for Clinical Chemistry. The book will describe analytical methods for detecting or quantifying toxic substances in biological fluids and tissues under urgent circumstances. Chapters have already been planned for a number of analytes. However, suggestions are welcome for additional drugs which are likely to be encountered clinically, which may on occasion produce emergency situations, and for which there are adequate analytical methods. Each analytical method must be an established one, fully described in the chemical and medical literature. The method should be optimal in terms of reliability and accuracy; ease and rapidity of performance and selectivity are additional desirable characteristics.
Participants are being sought to write chapters or evaluate methods. "Evaluation" means actually carrying out the analysis in a laboratory under realistic conditions with the objective of finding out how well the method works. Two or three evaluators are required for each method. For further information, interested persons should contact Christopher S. Frings, editor-in-chief, Cunningham Pathology Associates, 1025 South 18th St., Birmingham, Ala. 35256, 205933-8221, or Willard R. Faulkner, coeditor, Suite 607 Medical Arts Building, Vanderbilt University Medical Center, Nashville, Tenn. 37212; 615322-4277.
Award. The award, given annually for significant contributions to chromatography theory, instrumentation, or applications, will be presented at the 1984 Pittsburgh Conference on Analytical Chemistry and Applied Spectroscopy. Nominations accompanied by a brief bibliography and list of accomplishments related to chromatography should be submitted by June 15 to: Bernadene J. Sliwinski, USDA, ARS, Eastern Regional Research Center, 600 East Mermaid Lane, Wyndmoor, Pa. 19118.
Meetings The following meetings are newly listed in ANALYTICAL CHEMISTRY. Other 1983 meetings are listed in the January through April issues.
Suffet to Receive Environmental Science Award Irwin H. Suffet will be presented with the 1983 F. J. Zimmermann Award in Environmental Science at the 17th ACS Great Lakes Regional Meeting to be held June 1-3 in St. Paul, Minn. Suffet, professor of chemistry and environmental science at Drexel University, is being cited for his work on the development of methods for the purification of domestic water supplies. The F. J. Zimmermann Award, consisting of $1000 and a plaque, is given annually in recognition of scientific work having a significant impact on the protection of the environment. It is sponsored by the Central Wisconsin section of the American Chemical Society and Zimpro, Inc., a subsidiary of Sterling Drug.
