River algae affecting mercury pollution at Superfund site

From Science Daily:

“Dartmouth scientists and their colleagues have found that periphyton — a community of algae, bacteria and other natural material living on submerged surfaces — is helping to transform mercury pollution from a Superfund site along a New Hampshire river into a more toxic form of the metal.  The study also found lower than anticipated levels of methylmercury in crayfish, mayflies and small fish downstream from the former chemical plant along the Androscoggin River in Berlin, N.H., despite elevated methylmercury in the sediment, water and periphyton.  The results, which shed light on mercury dynamics within rivers and their food webs, appear in the journal Environmental Toxicology & Chemistry. … “
