The purpose of this book is to assess, evaluate, and give guidance on
the role of elemental speciation and speciation analysis in human health
hazard and risk assessment. The book is directed at risk assessors and
regulators to emphasize the importance of consideration of speciation in
their deliberations. To date, this issue has not been a part of most
hazard and risk assessments. Further aims of the publication are to
encourage the analysis of speciation of elements to increase knowledge
on the effect of speciation on mode of action and to increase
understanding of health effects.
