“…Dated depth profiles of Hg in sediment cores show changes in Hg accumulation rates over time that correlate well with documented Hg utilization and environmental releases and have been shown to be an accurate record of changes in external loading (Krabbenhoft et al 2007;Lockhart et al 2000;Lamborg et al 2002;Pirrone et al 1998;Engstrom and Swain 1997). Declining Hg accumulation rates in lake sediments and bog peat have been reported for many areas of the USA from 1970 through 1990 (Norton et al 1997;Engstrom and Swain 1997;Balogh et al 1999;Lorey and Driscoll 1999;Kamman and Engstrom 2002;Van Metre et al 2004;Perry et al 2005;Mahler et al 2006). These declining Hg accumulation rates have been at least partially attributed to improved wastewa-ter treatment, stricter regulatory controls on discharges to air and surface waters, and reductions in industrial use of Hg during the 1960s and 1970s.…”

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.

“…However, the large, relatively short-duration 1960s peak (10-15 y), suggests a major "point" source(s) rather than the Missouri-reservoir dilution effect or the continental-scale changes in atmospheric emissions of Hg from stationary sources implicated in Hg trends observed in most lake-sediment cores (Engstrom and Swain, 1997). Most lakes that are affected by non-point sources of Hg show a common pattern of gradually increasing concentrations (or loadings) (Perry et al, 2005;Engstrom et al, 2007;Muir et al, 2009). However, sediment cores collected from a few urban lakes show historical Hg patterns similar to Lake Whittington, where Hg concentrations increase and peak in the 1960s and 1970s and then decrease thereafter (Engstrom et al, 2007;Blumentritt et al, 2013).…”

“…An increase in heavy metal concentration is frequently mistaken for an increase in heavy metal flux, while it may be equally well explained by a decrease in the total sedimentation rate. Perry et al (2005) present a thorough analysis of sediment accumulation rate effects in relation to lake sediment Hg records.…”

Since the first studies reporting recent stratigraphic changes of metal concentration in lake sediments, many hundreds of studies have been published in the peer-reviewed literature. It is an impossible task to do justice to all of these works here; instead we: (1) examine recent methodological advances and place these in the context of the historical development of the discipline; and (2) explore the various purposes to which such methods have been applied. Such a historical emphasis may appear in conflict with the needs of a review of new approaches; however, this is not in fact the case for two main reasons. First, most new advances supplement rather than replace traditional methods, such that a thorough understanding of the practical and theoretical issues impacting these is still essential for reliable interpretation of palaeolimnological data. Second, while many of the new methods purport to circumvent problems, they achieve this only under favourable conditions, not dissimilar to the conditions that influence the earlier methods, so the same lesson must be learned anyway. Consequently, we use this historical narrative to address the fundamentals of the discipline.The chapter comprises two main parts; methodology and applications. The methodological section has three subsections: (1) Introduction to processes controlling natural variations in metal fluxes and concentrations in lake sediments; (2) Measurement of metal concentrations in sediments; (3) Calculation of enrichment or fluxes from sediment metal concentration data.There are four main applications subsections focusing on the value of lake sediment records of metals derived from mining or industry. They are: (1) Geochronological markers in sediments providing chronology for other research goals; (2) Lake sediment heavy metal records to quantify pollution loading histories, or to
