Sediment-water fluxes of mercury in Lavaca Bay, Texas

Article Abstract:

Using two testing methods, researchers analyzed mercury levels in the sediment of Lavaca Bay. Between 1966 and 1979, Lavaca Bay was contaminated with mercury from an Alcoa plant. The site was put on the EPA superfund list in March of 1994. Both interstitial pore water gradients and benthic flux chamber deployments showed that mercury deposition increased during dark periods at a rate higher than daylight periods. The exact reason for this is uncertain, but may be due to microbes that migrate relative to the amount of light, or an unidentified chemical process.

Investigation of porewater sampling methods for mercury and methylmercury

Article Abstract:

Researchers from the United States compared several methods of extracting porewater in estuarine sediments such as centrifugation, sediment filtration, dialysis and whole core squeezing for total mercury and for methylmercury.

Constructing a solution to a mercurial problem

Article Abstract:

The U.S. Department of Energy is constructing an artificial wetland at the Savanah River Site in South Carolina. The man-made marshland can provide data as to how it can eliminate mercury from surface water.
