Characterization of the dissolved organic matter present in the water of the Bío-Bío river, VIII Region of Chile
(Sociedad Chilena Química, 2016)
The dissolved organic matter in rivers has different origin and its composition can vary both by natural conditions and the anthropic activity that takes place near rivers. This mobile fraction of the organic matter is ...
Determination of mercury methylation potential in the presence of peat organic matter
(2013-08-01)
Methylmercury (MeHg) is a neurotoxin pollutant that accumulates in organisms and biomagnifies along the trophic chain. It is formed by the transfer of a methyl group to inorganic mercury (Hg). This transformation, termed ...
