Speciation and bioavailability of mercury in well-mixed estuarine sediments
Despite regulations controlling anthropogenic mercury sources in North America, high levels of mercury in coastal fish and shellfish are an ongoing problem in Maritime Canada and the Northeastern United States. This study presents sediment core data from a macrotidal estuary located at the mouth of the Bay of Fundy showing stratigraphic profiles of total and methylmercury concentrations and pot...
متن کاملInfluence of bioturbation by Hediste diversicolor on mercury fluxes from estuarine sediments: a mesocosms laboratory experiment.
Mercury, with its reactive forms being the most deleterious for the trophic chains, has been identified as a major pollutant in a few confined bodies of the coastal zone. Due to feeding, burrowing, and bioirrigation activities, infauna are known to play a crucial role in the biogeochemical processes of contaminants. The main goal of the present study is to evaluate the effects of Hediste divers...
متن کاملVolatilization of mercury under acidic conditions from mercury-polluted soil by a mercury-resistant Acidithiobacillus ferrooxidans SUG 2-2.
Volatilization of mercury under acidic conditions from soil polluted with mercuric chloride (1.5 mg Hg/kg soil) was studied with resting cells of a mercury-resistant strain, Acidithiobacillus ferrooxidans SUG 2-2. When resting cells of SUG 2-2 (0.01 mg of protein) were incubated for 10 d at 30 degrees C in 20 ml of 1.6 mM sulfuric acid (pH 2.5) with ferrous sulfate (3%) and mercury-polluted soi...
متن کاملDistribution of mercury in the upper sediments from a polluted area (Ria de aveiro, Portugal).
It is well known that chlor-alkali industries using mercury as a cathode are an important source of this heavy metal to aquatic environments. Once discharged into rivers, lakes or coastal waters, mercury accumulates in sediments and in the aquatic food web (Gonzalez, 1991). Both elemental mercury and its compounds are noxious to all living organisms, and are bioaccumulative and persistent. Meta...
متن کامل, Jr . MERCURY IN SEDIMENTS
In recent years, the Coastal Water Research Project has conducted surveys of the distribution of certain trace substances in sediments around the major municipal wastewater outfalls off southern California. Because of high levels of heavy metals found in sediments near Los Angeles County Sanitation Districts outfall system off Whites Point in 1970, detailed surveys of the Palos Verdes shelf wer...
