Mercury Mitigation Management Strategies and Likely Outcomes

This chapter examines the suite of major perturbations impacting the Everglades that have direct or indirect connections to mercury (Hg) cycling and trophic transfer leading to unacceptably high biota Hg concentrations and considers the likely efficacy of

Preface

If you want to grab the world and run it I see that you will not succeed. The world is a spiritual vessel, which can’t be controlled—Lao Tzu1

This book is the culmination of more than a 4-year effort to synthesize essentially 30 years of research into the mercury (Hg) problem in the Everglades. For Hg to enter food webs in aquatic ecosystems such as the Everglades, two things are required: first, of course, is a source of Hg; second is that the Hg in the aquatic ecosystem needs to be either present as or converted to the methylated form. Once Hg is methylated, it can enter the base of aquatic food web and then increasingly bioaccumulate by trophic transfer. This biogeochemical cycling of Hg is compl
