Monomethylmercury formation, the neurotoxic form of mercury, is mainly linked to anaerobic microbial activity. In order to assess the relative contribution of several microbial compartments (biofilms, raw water and sediment) we evaluated methylation of samples from ponds of temperate area (Lorraine, France) and from subarctic ponds (Nunavik, Quebec). Biofilms were not found to specifically promote mercury methylation, whereas sediment emerges as the main compartment involved in mercury methylation. The formation of methylmercury is positively linked to the temperature and to nutrients. Thus, by increasing the open water period, the water temperature and of the microbial activity, current climate changes may turn these ponds in preferential ...
