Book Description
Erich W. Bretthauer, Chairman of the Exposure and Hazard Assessment Working Group U. s. Environmental Protection Agency Washington, D. C. The efforts of the Exposure and Hazard Assessment Working Group were focused on the exchange of information on a variety of topics including research projects, regulations/statutes, analytical laboratories, and methods of exposure/risk assessment involving CDDs and CDFs. It was evident to the leaders of the Working Group that several of the knowledge voids had to be addressed on a fundamental level before expanded efforts could be made. Several questions needed to be answered: • Who has done research on this topic, and what do the data indicate? • Who is performing research now, and what are their capabilities? • How are other nations addressing this problem, and do they have legislative mandates in place? • Is there a general consensus on the topic? The members of the Working Group believed that these questions could be answered by surveying the major participants in the field of interest. Three principal survey efforts were performed by the Working Group, which collected information on research, regulations/statutes, and analytical laboratories from each of the participating nations. In addition to answering these fundamental questions, these efforts also fulfilled the major objectives of the entire Pilot Study. The collection, analysis, and distribution of information on research projects, regulations/statutes, and analytical laboratories were very useful efforts in helping to fill some of the basic knowledge voids.

Book Description
This book originated in a series of cross-disciplinary conversations in the years 1984-1990 between the editor, who is a physician-researcher involved in clinical and laboratory research, and a dioxin toxicologist. During the years in which the conversations took place, an extraordinary amount of new scientific literature was published related to dioxins, defined for purposes of this text as the chlorinated dibenzo-p-dioxins, dibenzofurans, polychlorinated biphe nyls (PCB's) and other compounds that are structurally and toxicologically similar to 2,3,7,8-tetrachlorodibenzo-p-dioxin (2,3,7 ,8-TCDD), the most extensively studied and most toxic of this group of chemicals. Dioxins also began to interest not only chemists and toxicologists, but also specialists from diverse disciplines such as wildlife and environmental science, immunology, neuroscience,public health, epidemiology, med icine, government, law, sociology, and journalism. Specialists from such varied disciplines, while familiar with their own literature, frequently did not have time to follow the dioxin literature outside their specialty area. In addition, each specialty had unique knowledge, methods, and perspectives. Cross disciplinary conversation was necessary, but all too frequently, specialists from the various disciplines did not speak the same language, resulting in misunderstanding.

Book Description
For almost four decades, controversy has surrounded the tactical use of herbicides in Southeast Asia by the United States military. Few environmental or occupational health issues have received the sustained international attention that has been focused on Agent Orange, the major tactical herbicide deployed in Southern Vietnam. With the opening and establishment of normal relations between the United States and the Socialist Republic of Vietnam in 1995, the time has come for a thorough re-examination of the military use of Agent Orange and other "tactical herbicides" in Southern Vietnam, and the subsequent actions that have been taking place since their use in Vietnam. The United States Department of Defense has had the major role in all military operations involving the use of tactical herbicides, including that of Agent Orange. This included the Department's purchase, shipment and tactical use of herbicides in Vietnam, its role in the disposition of Agent Orange after Vietnam, its role in conducting long-term epidemiological investigations of the men of Operation RANCH HAND, and its sponsorship of ecological and environmental fate studies. This book was commissioned by The Office of the Deputy Under Secretary of Defense (Installations and Environment) with the intent of providing documentation of the knowledge on the history, use, disposition and environmental fate of Agent Orange and its associated dioxin.

Book Description
By 1971 analytical scientists at Dow had good reason to believe that questions about "dioxin" (2,3,7,8-dibenzo-p-dioxin) had been appropriately addressed. This molecule had been identified as an unwanted trace contaminant in 2,4,5-trichlorophenol and its derivatives; synthesized and analytical standards prepared; characterized by all the known measurement techniques; and controlled in Dow products by newly developed analytical methods of confirmed integrity at levels 10 times lower than deemed necessary by Dow toxicologists. Thus we had not only fulfilled all the requirements of government agencies, we had gone the extra mile. No other product contaminant had been treated so rigorously. There was no doubt that Dow products were safe when used as directed. Once again we had proven that molecules could be successfully managed. Although there was already some noise decrying this conclusion, we were totally unprepared to weather the brouhaha which developed. "Dioxin" appeared to be a molecule that created fear and caused people to do strange (unscientific) things. Was it more than just a molecule? We now turned our attention to measuring the amount of "dioxin" in the environment. We were well prepared to develop methodology to do this. We had state-of-the-art equipment and some of the best chromatographers and mass spectroscopists in the world. We were confident we could find and measure "dioxin" (if present) in any matrix of interest at appropriate detection levels. Then we could determine how the dioxin got there and discover ways to completely control and manage the presence and movement of this molecule in the environment. This was our perception! This perception was reinforced by the merger of Dow analytical laboratories. For the first time powerful measurement tools would be under the same management as the separation systems. This created many opportunities for spectroscopists, chromatographers and instrument development folks to do extraordinary things together. The resulting laboratory, consisting of almost 200 technical people, was managed by a technical director and a technical manager. I was named technical manager, a position without a job description. We were not, however, positioned to communicate effectively with the world outside Dow. Those of us working in trace analysis had neither published much nor attended many scientific meetings outside the company. We had not honed either our writing or speaking skills. So our papers were rejected and we were seldom heard speaking. This took some years to correct as we didn't immediately recognize that we needed to have credibility with our peers in academia, government and other industry. In spite of this naivety on my part, I soon found myself serving on committees, task forces and study groups both within Dow and with government agencies in the United States and Canada. Immediately it became apparent to me that the integrity of analytical data at trace levels was a major problem. Different laboratories used different principles in the interpretation of signals. Consensus on data interpretation needed to be reached. But of even greater importance was the need to communicate with journalists. Each encounter with peers and others interested in "dioxin" became a great adventure filled with fun. Often these meetings were humorous, always challenging, sometimes testy scientists from industry always were portrayed as biased and even incompetent. So, "dioxin" appeared to cause people to do strange things. By means of anecdotal stories and essays this book attempts to convey the principal scientific and philosophical lessons learned, as well as reveal the astonishing behavior of those contributing to the frustration, agony and elation experienced by this industrial analytical chemist. Among the surprising lessons learned are: 1. Fear can create big business. 2. In a "crisis" situation, even
