As part of the Third National Health and Nutrition Evaluation Survey (NHANES 111), the Environmental Health Laboratory Sciences Division of the National Center for Environmental Health, Centers for Disease Control, will be analyzing human blood samples for trichloroethylene and other volatile organic compounds. These data will give an indication of the frequency of occurrence and background levels of these compounds in the general population.

For those of you who are not going on in a science career, passing the AP chemistry exam may fulfill the laboratory science requirement at the college, thus making more time available for you to take other courses. 

The author is deeply grateful to the editor of Annals of Clinical and Laboratory Science for granting permission to reprint from the author s article (N3) Figs. 1 to 5 and Tables 1 and 2, and to freely adapt from the text. The author is extremely grateful to Ms. Carol Perello for her painstaking and excellent secretarial support and to Dr. Herbert Spiegel for the opportunity provided to write this article. 

The Environmental Health Laboratory Sciences Division of the Center for Environmental Health and Injury Control, Centers for Disease Control, is developing methods for the analysis of bromomethane and other volatile organic compounds in blood. These methods use purge and trap methodology and magnetic mass spectrometry which gives detection limits in the low parts per trillion range.

This volume marks the first issue of a biannual publication for the Advances in Clinical Chemistry series. Starting this year, the series will be published twice a year to keep the readership abreast of the rapid changes and latest developments in clinical chemistry, clinical laboratory science, and laboratory diagnostics. 

I hope the readership will enjoy the first volume of 2005 and actively use it. As always, I warmly welcome comments and solicit participation in keeping subsequent volumes of the Advances in Clinical Chemistry series in the forefront of clinical laboratory sciences. 

Dr. Randolph earned a bachelor of science degree in chemistry and biology from Wayland College in Texas. He also holds a Ph.D. in experimental pathology from the Bowman Gray School of Medicine at Wake Forest University in Winston-Salem, North Carolina. He was introduced to his scientific career in clinical laboratory science at the Armed Forces Academy of Health Sciences, San Antonio, Texas during a 4-year tour of duty in the U.S. Army between 1972 and 1976.
