From 1860 to 1890, approximately 7 100 metric tons of metallic mercury (Hg) were released into the Carson River-Lahontan Reservoir watershed as a by-product of Comstock Lode silver (Ag) and gold (Au) ore refining. Present-day Hg contamination is most severe in mine tailings, where total Hg concentrations can exceed several hundred µg/g. Hg-laden tailings were also dumped directly into the Carson River, and were subsequently transported downstream into the Lahontan Reservoir and the Stillwater… 

Simulation of mercury transport and fate in the Carson River, Nevada

In 1991 the US EPA designated the Carson River as part of a Superfund site due to its high level of mercury contamination. Water column total mercury concentrations have been observed as high as 61 m

Mercury biogeochemistry in the Idrija river, Slovenia, from above the mine into the Gulf of Trieste.

Increases in total Hg and MeHg in the estuary demonstrate the remobilization of Hg, presumably as HgS dissolution and recycling, and high Hg levels persist into the Gulf.

Mercury in surface waters of three mine-dominated river systems: Idrija River, Slovenia; Carson River, Nevada; and Madeira River, Brazilian Amazon

This paper investigates the aqueous geochemistry of mercury (Hg) in three aquatic systems impacted by either past or present mining activities. The Idrija River in Slovenia flows near the Idrija

Redistribution of Mercury from Contaminated Lake Sediments of Clear Lake, California

Mining operations conducted at the Sulphur Bank Mercury Mine at Clear Lake, California, from 1872–1957, together with acid mine drainage since abandonment, deposited ca. 100 metric tons of mercury

Mercury concentrations and loads in a large river system tributary to San Francisco Bay, California, USA

During infrequent large floods, HgT concentrations relative to SSC were approximately twice as high as observed during smaller floods, indicating the transport of more Hg-contaminated particles during high discharge events.



Effect of Point and Diffuse Source Loadings on Mercury Concentrations in the Wabigoon River: Evidence of a Seasonally Varying Sediment–Water Partition

Ten years after major mercury loadings from a chlor-alkalai plant were sharply reduced, mercury levels in the surface sediments, water, and suspended sediments of the Wabigoon River downstream of

Mercury in swedish forest soils and waters — Assessment of critical load

As a result of air pollution, the content of Hg in fish has significantly increased in a large part of Scandinavia and North America. In this paper, the occurence and fluxes of Hg in Swedish forest

Mercury Hazards to Fish, Wildlife, and Invertebrates: A Synoptic Review

SUMMARY Available literature on the ecological and toxicological aspects of mercury (Hg) in the environment, with special reference to fish and wildlife resources, is reviewed and summarized.

Seasonal variability in the Mercury speciation of Onondaga Lake (New York)

Dissolved and particulate Hg speciation was determined on four occasions in the Spring to Fall interval of 1989, at three depths of the water column of Onondaga Lake, New York; an urban system in

Atmospheric Emission and Plant Uptake of Mercury from Agricultural Soils near the Almadén Mercury Mine

Surface soils collected near the Almaden, Spain, mercury mine reflected increasing concentrations of mercury (Hg) with proximity to the mine due to weathered mineral deposits and to atmospheric

Mercury in the surface water of Swedish forest lakes —concentrations, speciation and controlling factors

Concentrations of total Hg and five operationally defined Hg species were determined in the surface water of 25 Swedish forest lakes of different type. Regional and seasonal variations were studied

Compartmentalization of mercury in biotic components of terrestrial flood plain ecosystems adjacent to the South River AT Waynesboro, VA

Aquatic Hg contamination extending more than 200 km along the South River, South Fork of the Shenandoah River, and Shenandoah River in western VA has been recognized since 1977. Flooding has


Mercury, which is transported globally by atmospheric pathways to remote aquatic environments, is a ubiquitous contaminant at very low (nanograms Hg per liter) aqueous concentrations. Until recently,

Water Column Methylmercury in the Wabigoon/English River–Lake System: Factors Controlling Concentrations, Speciation, and Net Production

Ten years after major releases of inorganic mercury from a chloralkalai plant were sharply reduced, methylmercury (MeHg) levels remain markedly elevated in waters in most of the Wabigoon River system
