The relationship between the microbial methylation of mercury and the microbial activities in sediments and water collected from the estuary of Bilbao (North of Spain) was studied in three different sampling points and in two different seasons. Three different cultures were prepared with a sediment slurry to distinguish

Abstract. The effects of freshwater sediment components such as kaolinite, montmorillonite and birnessite (?-MnO2) on the biomethylation of mercury(II) in a synthetic growth medium (M-IIY) were assessed. Additions of kaolinite or montmorillonite to media containing mercuriC nitrate [Hg(NO3)2; 12 ?g Hg ml?1] had no
Centuries ago a tablespoonful of quicksilver was used to treat constipation.25 It arguably repre- sents one of the first uses of gravity in medicine. Among humans, the sole source of exposure to methyl mercury is the consumption of fish and sea mammals. Methyl mercury is produced environ- mentally by biomethylation of the
molecular and therapeutic perspective from studies that suggest that mercury is neurotoxic metal with diverse effects on lead to neural destruction and degenerative disease, mercury vapor exposure from dental amalgam has been demonstrated to . Methyl mercury is produced environmentally by biomethylation of the.
In this article we have shown how oxidation-reduction conditions can be correlated with biomethylation processes. In recent years we have been able to establish biogeochemical cycles for mercury and arsenic. We can now formulate a biogeochemical cycle for tin in some detail. The biomethylation of tin is interesting in two
