Report on how mercury (Hg) was examined in top-predator fish, bed sediment, and water from streams that spanned regional and national gradients of Hg source strength and other factors thought to influence methylmercury bioaccum. Sampled settings include stream basins that were agr¿l, urbanized, undeveloped, and mined. Predator fish were targeted for collection, and composited samples of fish were analyzed for total Hg (THg), as most of the Hg found in fish tissue is MeHg. Samples of bed sediment and stream water were analyzed for THg, MeHg, and characteristics thought to affect Hg methylation, such as loss-on-ignition and acid-volatile sulfide in bed sediment, and pH, dissolved organic carbon, and dissolved sulfate in water.

Download Mercury and the Everglades. A Synthesis and Model for Complex Ecosystem Restoration Book in PDF, ePub and Kindle
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.

Download Preparing for the Third Decade of the National Water-Quality Assessment Program Book in PDF, ePub and Kindle
The first two decades of the U.S. Geological Survey's National Water Quality Assessment (NAWQA) Program have provided a successful and useful assessment of U.S. water-quality conditions, how they have changed over time, and how natural features and human activities have affected those conditions. Now, planning is underway for the third decade (Cycle 3) of the Program outlined in the Science Plan, with challenges including ensuring that the NAWQA remain a national program in the face of declining resources, balancing new activities against long-term studies, and maintaining focus amidst numerous and competing stakeholder demands. The Science Plan for Cycle 3 articulates a forward-thinking vision for NAWQA science over the next decade, building on the previous cycles' data, experience, and products. Preparing for the Third Decade (Cycle 3) of the National Water-Quality Assessment (NAWQA) Program explains the national needs outlined in the plan, NAWQA's need to emphasize collaboration with other USGS and external programs, other federal agencies, state and local governments, and the private sector.
