Technological systems become organized by commands from outside, as when human intentions lead to the building of structures or machines. But many nat ural systems become structured by their own internal processes: these are the self organizing systems, and the emergence of order within them is a complex phe nomenon that intrigues scientists from all disciplines. Unfortunately, complexity is ill-defined. Global explanatory constructs, such as cybernetics or general sys tems theory, which were intended to cope with complexity, produced instead a grandiosity that has now, mercifully, run its course and died. Most of us have become wary of proposals for an "integrated, systems approach" to complex matters; yet we must come to grips with complexity some how. Now is a good time to reexamine complex systems to determine whether or not various scientific specialties can discover common principles or properties in them. If they do, then a fresh, multidisciplinary attack on the difficulties would be a valid scientific task. Believing that complexity is a proper scientific issue, and that self-organizing systems are the foremost example, R. Tomovic, Z. Damjanovic, and I arranged a conference (August 26-September 1, 1979) in Dubrovnik, Yugoslavia, to address self-organizing systems. We invited 30 participants from seven countries. Included were biologists, geologists, physicists, chemists, mathematicians, bio physicists, and control engineers. Participants were asked not to bring manu scripts, but, rather, to present positions on an assigned topic. Any writing would be done after the conference, when the writers could benefit from their experi ences there.

As society has become increasingly aware of the potential threats to human health due to exposures to toxic chemicals in the environment and the workplace and in consumer products, it has placed increased demands upon the still-fledgling science of toxicology. As is often the case when science is called upon to supply firm answers when pertinent information and fundamental knowledge are lack ing, both the scientific and the social issues become confused and new tensions develop. One of the major purposes of this book is to focus on those aspects of the science of toxicology that pertain most to social issues-namely, analysis of risk for purposes of human health protection. Although it is apparent that the discipline of toxicology is not yet prepared to provide firm answers to many questions concerning human risk, it is important that the rigorously derived information be used in the most objective and logical way to yield the closest approximation to the truth. This book is designed to sup ply as much guidance for such tasks as is permitted by the current state of our knowledge. Its emphasis is thus placed on interpretation of toxicity data (broadly defined) for assessing risks to human health. In this way, it differs from other basic toxicology texts, most of which emphasize methods for performing studies or describe various toxicological endpoints and classes of toxic agents.
