The ever-increasing release of harmful agents due to human
activities has led in some areas of the world to heavy pollution.
In order to protect human health and the environment, environmental
standards that shall limit the release and the concentration of
those toxic agents in the environment and hence the exposure to it
have to be established. The related assessment and decision-making
procedures have to be based on solid scientific data about the
effects and mechanisms of these agents as well as on ethical,
social and economic aspects. For risk evaluation, the knowledge of
the dose response curve is an essential prerequisite. Dose
responses without a threshold dose are most critical in this
connection. Such dose responses are assumed for mutagenic and
carcinogenic effects, which, therefore, dominate also the
discussion in this book. In the environmentally important low dose
range, risk estimation can only be achieved by extrapolation from
higher doses with measurable effects. The extrapolation is
accompanied with uncertainties which makes risk evaluation as well
as risk communication frequently problematic. In order to ensure
rational efficient and fair decisions beyond a sound scientific
assessment the dialogue between disciplines, with the affected
people and with the general public is necessary. In this book, the
whole range of relevant and essential aspects of risk evaluation
and standard setting is addressed. Starting with the ethical
foundations, the sound analysis of recent scientific findings sets
the frame for further reflections by theory of cognition,
psychosocial sciences, and jurisprudence. The authors end up with
concluding recommendations for coping with the recentproblems of
standard setting in the field of environmentally relevant low
doses. The book is designed to a readership of scientists,
legislators, administrators, and the interested public.
