Sulfate simulation of mercury methylation in freshwater sediments
Article Abstract:
The increase in the rates of of transformation of inorganic mercury to methylmercury due to an increase in sulfate levels in freshwater ecosystems is studied. Anoxic sediment slurries and lake water above above intact sediment cores were subjected to experimental additions of sulfate. The linkage between mercury methylation in freshwater sediments and sulfate reduction was established.

Marine bacterial degradation of brominated methanes
Article Abstract:
Bacteria found in seawater is not able to completely degrade brominated methanes, which are produced by sources such as marine algae. The bacteria is able to degrade dibromomethane, but it is not as successful in degrading bromoform. However, this degradation of dibromomethane is inhibited by the presence of nitrifiers and methanotrophs.
