“…Louis and others, 2004;Orem and Increased precipitation intensity and frequency of storm events are likely to lead to increased mercury inputs to aquatic systems (Krabbenhoft and Sunderland, 2013). Also, extreme dry periods punctuated by large rainfall events will likely increase methylmercury production in many settings (Monson, 2009;Orem and others, 2011).…”

The quality of our nation's waters : mercury in the nation's streams-levels, trends, and implications / by Dennis A. Wentz, Mark E. Brigham, Lia C. Chasar, Michelle A. Lutz, and David P. Krabbenhoft. ForewordThe United States has made major investments in assessing, managing, regulating, and conserving natural resources, such as water, minerals, soil, and timber. Sustaining the quality of the Nation's water resources and the health of our ecosystems depends on the availability of sound water-resources data and information to develop effective, science-based policies. Effective management of water resources also brings more certainty and efficiency to important economic sectors. Taken together, these actions lead to immediate and long-term economic, social, and environmental benefits that make a difference to the lives of millions of people.The U.S. Geological Survey (USGS) is committed to providing the Nation with reliable scientific information that helps to enhance and protect the overall quality of life and that facilitates effective management of water, biological, energy, and mineral resources (http://www.usgs.gov). Information on water resources is critical to ensuring long-term availability of water that is safe for drinking and recreation, and that is suitable for industry, irrigation, and fish and wildlife. Population growth and increasing demands for water make the availability of water, measured in terms of quantity and quality, essential to the long-term sustainability of our communities and ecosystems.Mercury is a pervasive contaminant of streams and lakes, and has resulted in fish consumption advisories in all 50 States. The current report, "Mercury in the Nation's Streams-Levels, Trends, and Implications," presents a summary of results from USGS investigations conducted since the late 1990s on the sources, occurrence, trends, transport, and bioaccumulation of mercury in stream ecosystems. The report draws from studies conducted by several USGS Programs, including the National WaterQuality Assessment, Toxics Substances Hydrology, and National Research Programs. This report is one of a series of publications, The Quality of Our Nation's Waters, which describe major findings of the USGS on...

“…In the midwest, most of the samples were collected during the late 1980s and 1990s, whereas most of the samples in the southeast were collected during the late 1990s and early 2000s. Monson (2009) reported downward trends for Hg concentrations in northern pike and walleye fromMinnesota lakes before the mid-1990s, followed by upward trends after the mid-1990s. Statewide trends, 1996Statewide trends, -2005 Fish Hg data, aggregated by state and by species, were also evaluated from 1996 to 2005 for comparison with wet Hg deposition during the same period (Table 4).…”

A national dataset on concentrations of mercury in fish, compiled mainly from state and federal monitoring programs, was used to evaluate trends in mercury (Hg) in fish from US rivers and lakes. Trends were analyzed on data aggregated by site and by state, using samples of the same fish species and tissue type, and using fish (1996)(1997)(1998)(1999)(2000)(2001)(2002)(2003)(2004)(2005) were compared to wet Hg deposition data from the Mercury Deposition Network (MDN) over the same period. Downward trends in Hg concentrations in fish from data collected during 1969-1987 exceeded upward trends by a ratio of 6 to 1. Declining Hg accumulation rates in sediment and peat cores reported by many studies during the 1970s and 1980s correspond with the period when the most downward trends in fish Hg concentrations occurred. Downward Hg trends in both sediment cores and fish were also consistent with the implementation of stricter regulatory controls of direct releases of Hg to the atmosphere and surface waters during the same period. The southeastern USA had more upward Hg trends in fish than other regions for both site and state aggregated data. Upward Hg trends in fish from the southeastern USA were associated with increases in wet deposition in the region and may be attributed to a greater influence of global atmospheric Hg emissions in the southeastern USA. No significant trends were found in 62% of the fish species from six states from 1996 to 2005. A lack of Hg trends in fish in the more recent data was consistent with the lack of trends in wet Hg deposition at MDN 176 Environ Monit Assess (2011) 175:175-191 sites and with relatively constant global emissions during the same time period. Although few significant trends were observed in the more recent Hg concentrations in fish, it is anticipated that Hg concentrations in fish will respond to changes in atmospheric Hg deposition, however, the magnitude and timing of the response is uncertain.

“…Indeed, pH remained stable in most lakes, and increased in relatively few lakes, in Ontario, Quebec, Nova Scotia, and Newfoundland during the 1990s, perhaps requiring decades before pH increases in most lakes (e.g., Kemp 1999, Clair et al 2002, Jefferies et al 2003a. Similarly, methylmercury concentrations increased in fish and loons in widely scattered eastern locations between the mid-1990s and mid-2000s (Madsen and Stern 2007, Monson 2009, Rasmussen et al 2007, Wyn et al 2010.…”

“…In addition, methylmercury concentrations are increasing in some locations because of multiple interacting factors that cause methylmercury to increase even though mercury deposition and acid precipitation have declined (Watras and Morrison 2008). For example, methylmercury increased in fish between the mid-1990s and mid-2000s in Wisconsin, Minnesota, and Nova Scotia (Madsen and Stern 2007, Monson 2009, Rasmussen et al 2007, Wyn et al 2010 and mercury increased in Common Loons from 2002 to 2010 in Wisconsin (Meyer et al 2011). Similarly, pH increased in relatively few lakes in eastern Canada during the 1990s, despite concurrent reductions in acid emissions, partly because the acid neutralizing capacity of most lakes remained insufficient to buffer acid inputs (Doka et al 2003, Jefferies et al 2003a.…”

ABSTRACT. Reproductive success of Common Loons (Gavia immer) is a powerful indicator of aquatic ecosystem health, especially in relation to mercury and acid precipitation. We examined relationships between Common Loon reproductive success and longitude, year, lake area, and pH across southern Canada using data collected from 1992 to 2010 by participants in Bird Studies Canada's Canadian Lakes Loon Survey. Our goal was to indirectly describe the health of lakes in southern Canada with respect to mercury and acid precipitation. The overall model-predicted number of six-week-old young per pair per year was 0.59 (95% confidence limits: 0.56-0.62). Six-week-old young per pair per year decreased by 0.19 from west-to-east (−127° to −52° longitude), decreased by 0.14 between 1992 and 2010, increased by 0.22 as lake area increased from 10 to 3000 ha, and increased by 0.43 as acidity decreased from pH 5 to 9. The relationships were likely linked to acid-and temperature-mediated exposure to methylmercury and/or acid-induced reductions in forage fish. The temporal decrease
