Critical research needs include definition of thresholds for adverse health effects and how these thresholds vary with exposure concentration and duration. Such data would be valuable for affirming AEGL values. Additionally, the mode of dimethylhydrazine toxicity is not fully understood and, therefore, research providing insight into the underlying mechanism(s) of dimethylhydrazine toxicity would reduce current uncertainties in quantitative health risk issues. 

This disastrous consequence comes about because intellectuals in less developed countries (LDCs), far from treating the preoccupations of the residents of economically developed countries as affectations of the very rich, adopt these same worries. Craven and Stewart provide an instructive analysis of risk issues in France and the francophone African state of Burkina Faso.1 The medical, environmental, geographical, and political problems of Burkina Faso are radically different from those in France, but intellectuals in Burkina Faso and college students in France responded similarly to questions about risk. In fact, intellectuals in Burkina Faso had borrowed concerns relevant only to France, and their opinions were reflected in the national media. Thus,...

Risk issues are often emotional. They are contentious. Disagreement is often deep and fierce. This is not surprising, given that how we perceive and respond to risk is, at its core, nothing less than survival. The perception of and response to danger is a powerful and fundamental driver of human behavior, thought, and emotion. [22]... 

In the winter of 1995 we gathered thirty experts in an Amsterdam hotel to get to the bottom of the fundamental misunderstandings over chemical risk regulation. Half of the experts were natural scientists working on chemical risk issues toxicologists,... 

How difficult risk cotiununication might be, depends on the complexity of the risk issues to be handled [3] ... 

New methods of inter-active ways of debating issues, including perceived costs and benefits of specific measures must also be developed and fed into policy decisions. Discussions and decisions in the context of risk issues are interdisciplinary and must be tackled across boundaries of expertise for an intensive exchange of ideas. Risk communicators should be aware of and remember the different risk perspectives and take them into account in Iheir risk communication efforts. 

The history of technology reveals that safety and risk issues have often been handled with a mixture of attitudes and approaches, including consideration of the following (Sorensen, 1982). 

The channel of communication is also an important variable in the communication process. Survey researchers have examined the relative credibility of various channels, including print media, radio and television, magazines, and advertising, and have found differences in the degree of trust people have in each. These differences depend not only on the class of channel but also on the specific representative of that class. For example, coverage of a risk issue in a local newspaper may be viewed differently from stories on the same issue in the national press. 

The scope of the report should reflect the interests and information needs of the intended target audience(s). For example, investors will likely be most interested in a report that covers a company s entire operations and focuses on key financial risk issues. Local residents will likely prefer to see information presented at the facility level, allowing them to consider the performance of their local facility relative to other facilities owned by the company. 

Haber, Lynne has more than 12 years of experience in applying risk assessment methods in evaluating the toxicity, toxicokinetics, and mode of action of chemicals. Her current interests are in the application of mechanistic information in risk assessment and in methods for extending the dose-response curve to low doses. Other current work includes research on children s risk issues, consideration of mode of action in cancer risk assessment, incorporating data on polymorphisms into risk assessment, and development of scientifically based occupational exposure limits. 

As a final point we need to focus attention on a critically important risk issue that has been entirely neglected in this book, and that is only beginning to draw the attention it deserves. Our concern in this book has been focused on the effects on human health of exposures to environmental chemicals. We have not discussed how these chemicals may damage non-human life forms and even the inanimate environment (e.g., the ozone layer). This is an immense topic about which information is limited, but which could, in the long term, be more important in several respects than the topic of this book. An associate of mine has remarked that, somehow, the E has been taken out of EPA, suggesting that the agency has devoted much more attention to human health protection than to environmental protection. The lack...

Each of these principles thus expands a regulatory agency s discretionary authority to adopt common sense solutions to the difficult safety/risk issues that it faces.
