Environmental pollution is one of the most serious threats to the future health of our planet. A wide and ever increasing range of chemicals from industry, agriculture, medicine and a host of other sources continue to contribute to the earth’s chemical load. Governments have encountered great difficulties responding to the crucial and immediate need for effective management.

This book aims to bridge the gap between ecotoxicology and limnology. The intended readers of the book are water managers, policy makers with a scientific background as well as researchers/advisors in the area of water management. The book provides an ecotoxicological perspective on lake management and describes eutrophication of shallow, temperate lakes. It surveys the influence of toxic substances (e.g., agricultural pesticides) on the aquatic ecosystem, especially the relation between algae and daphnids. The message of the book is that nutrients such as phosphorus are not the only important factor in explaining and managing eutrophication: toxic disturbance of to-down control is also an important factor to be considered. The results of extensive studies and experiments (some unpublished) on lake eutrophication are presented in this book.

The science of ecotoxicology and the practice of ecological risk assessment are evolving rapidly. Ecotoxicology as a subject area came into prominence in the 1960s after the publication of Rachel Carson’s book on the impact of pesticides on the environment. The rise of public and scientific concern for the effects of chemical pollutants on the environment in the 1960s and 1970s led to the development of the discipline of ecotoxicology, a science that takes into account the effects of chemicals in the context of ecology. Until the early 1980s, in spite of public concern and interest among scientists, the assessment of ecological risks associated with natural or synthetic pollutants was not considered a priority issue by most government. However, as the years passed, a better understanding of the importance of ecotoxicology emerged and with it, in some countries, the progressive formalization of an ecological risk assessment process. Ecological risk assessment is a conceptual tool for organizing and analyzing data and information to evaluate the likelihood that one or more stressors are causing or will cause adverse ecological effects. Ecological risk assessment allows risk managers to consider available scientific information when selecting a course of action, in addition to other factors that may affect their decision (e. g. , social, legal, political, or economic). Ecological risk assessment includes three phases (problem formulation, analysis, and risk characterization).
