This book will present a detailed analysis of how some current ecological risk assessment (ERA) studies fall short of their intended mark. It will discuss the limitations of these studies and explain how sometimes their premises are fundamentally flawed, thus producing data that is not particularly useful. The analysis will explain that learning from past mistakes coupled with a willingness to experiment outside of the conventional studies, can lead to numerous new and useful studies that can make for significant gains in ERA. The new studies presented in the book will be strategically grouped, facilitating readers locating those that relate to their individual areas of expertise.
