Note
It is our hope that the chapters we have compiled in this book accurately reflect the state of the science of toxicology of marine mammals as the field crosses the bridge into the twenty-first century. This is an area of research that will most likely make its major future advances through the applications of multidisciplinary and interdisciplinary approaches that are often international in scope. This is because of the complexity of the challenges posed to the study of the effects of high numbers of chemical substances in long-lived and wide-ranging mammals of the seas and large inland waters.
