How to Implement and Profit from a Successful Laboratory Automation Program
EnviroSolutions Consulting, Inc.
172 Camelot Way, #20198
Jasper, GA 30143

Donald G. Patterson Jr. earned his BA degree from the University of Northern Colorado and his Ph.D. in Organic Chemistry from Arizona State University. Following three years of post-doctorate research with Professor Carl Djerassi at Stanford University, he joined the Toxicology Branch at the Centers for Disease Control and Prevention (CDC) in 1979. He was a member of the Senior Biomedical Research Service within the Organic Analytical Toxicology Branch within the Division of Laboratory Sciences at CDC until his recent retirement after 29 years of U.S. Government service. He is currently President of EnviroSolutions Consulting, Inc. and his current interests include the development and application of new and novel methods for sensitive, specific, fast, and accurate quantitative analysis for environmentally significant compounds in human tissues. These human biomonitoring methods generally involve the use of rapid automated sample preparation coupled with isotope-dilution high resolution mass spectrometry and various other techniques; such as multidimensional comprehensive gas chromatography (GCxGC). The goal of this research is to dramatically increase the laboratory throughput and sensitivity; thereby reducing the cost of large scale human exposure assessment for epidemiologic studies designed to assess any potential human health effects from exposure to environmentally significant chemicals. He has authored and co-authored more than 370 journal articles as well as 10 book chapters.

Bert van Bavel is a professor in analytical chemistry at the MTM Research Center at the Örebro University in Sweden . After receiving his master degree at the University of Amsterdam, he received a PhD from the Umeå University, he spent time working in the US as a senior scientist at STL and two periods as a guest professor at the Kyoto University and Shimadzu Techno Research. He is currently head of MTMs analytical laboratory including the dioxin lab. He is the co-author of more than 200 publications in environmental chemistry and organises each year one of the largest QA/QC programs on dioxin analysis. His research interest cover all from the analysis of dioxins and traditional chlorinated POPs, brominated flame retardants to perfluorinated compounds. Professor Bert van Bavel is one of the experts for UNEP leading laboratory inspections to assess existing capacity and capacity building needs to analyse POPs in developing countries.

Multi-residue Extraction and Clean Up of Pesticides and POPs in Dried Botanicals Using PLE
US Food and Drug Administration, Office for Regulatory Science          
College Park, MD 20740

For the past 15 years he has served as an expert on dioxins and related compounds for the US Food and Administration’s Center for Food Safety and Applied Nutrition. Current recent interests include the automation for POPs analysis and method development for pesticides and POPs in fruits, vegetables and dietary supplements with full scan high resolution mass spectrometry.  Prior to FDA, he worked for the California EPA on environmental health investigations of dioxins, PCBs and metals involving aquatic systems and farm animals. He has authored 30 research articles, book chapters and reviews. He received a MPH in Environmental Health Sciences at U. C. Berkeley 1991 and a MS in Chemistry in 1978 from U. C. San Diego.

Automation in Dioxin Analysis   
RIKILT-Institute of Food Safety
The Netherlands

Wim (W.A.) Traag, started his professional career at the Rijkszuivelstation in Leiden in 1973 and works at RIKILT since 1977. He is currently a senior scientist on pesticides, contaminants and mycotoxins and the project manager for the development of mass spectrometric methods of analysis for organic contaminants in feedstuffs and food. He has been involved in dioxin analysis since 1990 and was actively involved in all major incidents related to dioxins in the food chain, starting with the problems around the MWIs near Rotterdam, and later the citrus pulp incident, the Belgian affair (first samples analyzed at RIKILT). He participated in the EU-DIFFERENCE project dealing with the validation of new analytical methods for dioxins and the development of reference materials. Since 2004 he is project manager of the rapid alert system of RIKILT as part of the service level agreement between RIKILT and the Government.

Historical Evolution and Lessons Learned for Automated High Throughput Sample Preparation of Biological Matrices
Centers for Disease Control and Prevention
Atlanta, GA

For more than twenty years, Wayman Turner has served as Chief of the Dioxin and Persistent Organic Pollutants (DOXPOPs) Laboratory, Organic Analytical Toxicology Branch (OAT), Division of Laboratory Science (DLS), National Center for Environmental Health (NCEH), Atlanta, GA.  The DOXPOPs Laboratory performs: (1) sample preparation of human specimens using high-throughput automated sample cleanup and enrichment techniques, (2) ultra-trace quantification of over 150 persistent environmental toxicants using high-resolution gas chromatography and isotope-dilution high-resolution mass spectrometry (HRGC/ID-HRMS) technology and (3) data handling, quality assurance/ quality control (QA/QC) and data reporting.  These analytical measurements are performed in support of numerous large-scale epidemiological and health effects studies on various populations from around the world potentially exposed to 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) and other polychlorinated dibenzo-p-dioxins (PCDDs), dibenzofurans (PCDFs), biphenyls (PCBs), persistent organochlorine pesticides (OCs), polychlorinated naphthalenes (PCNs), polybrominated diphenylethers (PBDEs) and polybrominated dioxins and furans (PBDDs/PBDFs).  Wayman Turner continues to be actively involved in research and development of new “state-of-the art” analytical methods to accurately measure ultra-trace levels of environmental toxicants in human specimens.
