Mercury and the Everglades. A Synthesis and Model for Complex Ecosystem Restoration, 1st ed. 2019
Volume II – Aquatic Mercury Cycling and Bioaccumulation in the Everglades

This book integrates 30 years of mercury research in the Florida Everglades to inform scientists and policy makers. The Everglades is an iconic ecosystem by virtue of its expanse; diversity of biota; and multiple international designations. Despite this, the Everglades has been subjected to multiple threats including: habitat loss, hydrologic alterations, invasive species and altered water quality.  Less well recognized as a threat to Everglades human use and wildlife populations is the toxic metal, mercury.  

 

The first half of Volume II focuses on biogeochemistry and factors unique to the Everglades that make it extraordinarily susceptible to mercury methylation following its deposition: warm subtropical climate, shallow depth, high levels of dissolved organic matter, sulfate contamination, nutrient enrichment and sediment redox conditions (for review of atmospheric mercury deposition significance, see Vol. I). The second half of Volume II answers the ?so what? question ? why biomagnification of the methylmercury produced in the Everglades is a threat to the health of top predators including humans.  The results of the synthesis presented in Volume II suggest that the mercury problem in the Florida Everglades is one of the worst in the world due to its areal extent and the degree of risk to ecological receptors and humans.

Darren Rumbold is a Professor of Marine Science and Director of the Coastal Watershed Institute at Florida Gulf Coast University (FGCU). He earned a BA in Chemistry and a BS and MS in Biology from Florida Atlantic University. He completed his Ph.D. in the Department of Marine Biology and Fisheries at University of Miami’s Rosenstiel School of Marine and Atmospheric Science in 1996. In 1997, he was awarded a U.S. EPA Environmental Science & Engineering Fellowship at the National Center for Environmental Assessment in Washington, DC. From 1998-2006, he served as Senior- and, later, Lead Scientist with South Florida Water Management District (SFWMD) overseeing a program to learn the influential factors controlling mercury biogeochemistry, fate and effects in the Everglades. During his tenure, he served as Module lead under the Comprehensive Everglades Restoration Plan (CERP) coordinating efforts of state and federal agencies working on mercury. He also served as Technicallead for the Water Quality Team of the Southwest Florida Feasibility Study. In 2006, Dr. Rumbold joined the faculty of FGCU where he mentors students in taking a landscape-scale approach in assessing impacts of high-volume, freshwater discharges and the transport and fate of nutrients, mercury and other toxicants transported through the coastal watershed. As principal investigator (PI) or co-PI, he has secured millions in extramural funding for research; most recently, up to $4.1 million to provide ecological and environmental scientific support, on an as-needed basis, to the SFWMD.
