The subject of this volume--uncertainties in risk assessment and
management--reflects an important theme in health, safety, and
environ mental decision making. MOst technological hazards are
characterized by substantial uncertainty. Recent examples include
nuclear waste disposal, acid rain, asbestos in schools, carcinogens
in food, and hazardous waste. realing with such uncertainty is
arguably the most difficult and challeng ing task facing risk
assessors and managers today. Four primary sources of uncertainty
in risk assessment and management can be identified: (1)
uncertainties about definitions; (2) uncertainties about scientific
facts; (3) uncertainties about risk perceptions and atti tudes; and
(4) uncertainties about values. Uncertainties about definitions
derive primarily from disagreements about the meaning and
interpretation of key concepts, such as probability. Uncertainties
about scientific facts derive primarily from disagreements about
failure modes, the probability and magnitude of adverse health or
environmental consequences, cause and effect relationships,
dose-response relationships, and exposure patterns. Uncertainties
about risk perceptions and attitudes derive primarily from
disagreements about what constitutes a significant or acceptable
level of risk. Uncertainties about values derive primarily from
disagreements about the desirability or worth of alternative risk
management actions or conse quences. The papers in this volume
address each of these sources of uncertainty from a variety of
perspectives. Reflecting the broad scope of risk assess ment and
risk management research, the papers include contributions from
safety engineers, epidemiologists, toxicologists, chemists,
biostatisticians, biologists, decision analysts, economists,
psychologists, political scien tists, sociologists, ethicists, and
lawyers.
