As rising levels of mercury in the environment pose an increasing threat of toxicity to humans and wildlife, several laws already call for industries to reduce mercury emissions at the source. Ecosystem Responses to Mercury Contamination: Indicators of Change outlines the infrastructure and methods needed to measure, monitor, and regulate the conce

"Mercury deposition and contamination is widespread and well documented, and it continues to be a public-health concern for certain sectors of the global human population in both developed and developing countries. This edited volume focuses on integrating the diverse sciences involved in the process of mercury cycling in the environment--from the atmosphere, through terrestrial and aquatic food webs, and human populations--to develop a comprehensive perspective on this important environmental pollutant. Using a systems-level approach, this book provides recommendations on mercury remediation, risk communication, education, and monitoring. In response to a growing need for understanding the cycling of this ubiquitous pollutant, the science of mercury has grown rapidly, expanding into several interdisciplinary fields and encompassing such disparate academic and scientific disciplines as biogeochemistry, economics, sociology, public health, decision sciences, physics, global change, and mathematics. Only recently have scientists really begun to establish more holistic approaches to studying mercury pollution, giving rise to investigations that have furthered the integration of a multi-tiered approach, especially by using chemistry, biology, and human health sciences collectively. The study of mercury pollution has produced a variety of contributions to domestic and international policies related to the management of mercury in the environment"-- Provided by publisher.

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.

Anthropogenic emissions of mercury into the atmosphere have increased mercury deposition that, in turn, has led to a large legacy of mercury accumulation in terrestrial ecosystems and increased mercury contamination of surface waters. Despite efforts to control anthropogenic emissions of mercury, it is possible that release of mercury historically deposited to forests and wetlands will moderate the recovery of aquatic ecosystems. This research examined the biogeochemical cycling of mercury in different wetland types in the Adirondack region of New York and in a forested headwater catchment during snowmelt at the Hubbard Brook Experimental Forest (HBEF) in the White Mountains of New Hampshire. Mercury pool size varied across the upland-wetland interface, among wetland types, across individual wetland transects, and along depth profiles in soils of forests and wetlands of the Adirondack region. In mineral horizons of uplands and shallow peat riparian wetlands, mercury was strongly correlated with carbon (p=0.002, r2=0.73), and nitrogen (p0.001, r2=0.82), but not sulfur. In contrast, there was a strong correlation between mercury and sulfur in peat of headwater wetlands (p
