This book is the final installation in a three-volume series synthesizing 30 years of mercury research in the Florida Everglades. The first part of this book evaluates the occurrence of trends in both biota mercury concentrations and atmospheric mercury deposition. Through both empirical and deterministic analyses, the likely drivers of biota trends are identified. These analyses help lay the predicate for devising an overall strategy to mitigate and manage the Everglades mercury problem. The book concludes with a model analysis of the likely benefits and uncertainty attendant with implementing the leading candidate strategy for best reducing the Everglades mercury problem.
