International audience; Abstr act Methylation and demethylation represent major transformation pathways regulating the net production of methylmercury (MMHg). Very few studies have documented Hg reactivity and transformation in extreme high-altitude

International audience; Periphyton relevance for methylmercury (MeHg) production and accumulation are now well known in aquatic ecosystems. Sulfate-reducing bacteria and other microbial groups were identified as the main MeHg producers, but the effec

Sulfate-Reducing Bacteria in Floating Macrophyte Rhizospheres from an Amazonian Floodplain Lake in Bolivia and Their Association with Hg Methylation

Autor: L. Alanoca, Volga Iñiguez, Marc Roulet, Darío Achá, Samanta Sanchez, Jean Remy Davée Guimarães, Ruddy Luna

Publikováno v: Applied and Environmental Microbiology. 71:7531-7535

Five subgroups of sulfate-reducing bacteria (SRB) were detected by PCR in three macrophyte rhizospheres (Polygonum densiflorum, Hymenachne donacifolia, and Ludwigia helminthorriza) and three subgroups in Eichhornia crassipes from La Granja, a floodpl

Sources of mercury in surface waters of the Upper Madeira erosive basins, Bolivia

Autor: L. Maurice-Bourgoin, P. Vauchel, L. Alanoca, P. Fraizy

The human activities impact on the mercury (Hg) distribution in the Amazon waters is still discussed but very few information regarding the Hg sources from the highly turbid Andean headwaters have been published. The annual load of suspended sediment
