Environmental Toxicology is a welcome addition to the Cambridge University Press Environmental Chemistry Series. The inclusion of a textbook on toxicology in a series devoted to environmental chemistry might, at first glance, appear surprising. However, as will become evident to the reader, the authors have approached their topic in a truly interdisciplinary manner, with environmental chemistry playing a prominent role in their analysis. Environmental toxicology is a young and dynamic science, as pointed out by the authors in their welcome historical perspective of its development over the past 30+ years. One of the inevitable consequences of the rapid evolution of this area of science has been the scarcity of useful textbooks. Several multiauthored books have appeared in recent years, usually consisting of specialised chapters written by researchers familiar with a specific area of environmental toxicology.
